Anti-Developmental Biases in Thesaurus Design

A somewhat abridged version appears in Fred W. Riggs (Ed.): The CONTA Conference: Proceedings of the Conference on Conceptual and Terminological Analysis in the Social Sciences.

A number of biases seem to manifest themselves frequently in the process of thesaurus construction. These biases are inherently anti-developmental, introduce distortions into the design process and constitute obstacles to social development. The effect of these biases is particularly serious in the social science domain.

This is a preliminary investigation, intended to open up discussion. The supporting arguments and evidence are not presented here, although they form part of the argument of several earlier papers (1,2,3,4,5).

Bias 1: Static Bias Associated with Noun Categories

Most thesauri are concerned solely with ordering nouns or objects (called 'subjects'). The position of the noun in the schemes may be affected by an adjectival qualifier, but the emphasis remains nevertheless on bounded objects (even if they are abstract). The result of the use of any such Thesaurus is therefore necessarily static - a static assemblage of nouns.

This point is argued by Burger in a paper for this conference (6) a theoretical physicist David Bohm has explored the same question from 1 own perspective:

    "In chapter 2 we go into the role of language in bringing about fragmentation of thought. it is pointed out that the subject-verb-object structure of modern languages implies that all action arises in a separate subject, and acts either on a separate object. or else reflexive on itself. This pervasive structure leads in the whole of life to a function that divides the totality of existence into separate entities, which are considered to be essentially fixed and static in their nature. i then inquire whether it is possible to experiment with new language forms in which the basic role will be given to the verb rather than the noun. Such forms will have as their content a series of action that flow and merge into each other, without sharp separation or breaks. Thus, both in form and in content, the language will be in harmony with the unbroken flowing movement of existence as a whole. (7, p. XII).
The fundamental characteristic of development is change and movement. The essential problem of development is how to initiate and guide development and render it self-controlling as a social process.

Can thesauri, using essentially static categories, adequately order information relevant to development? Clearly static schemes have a role to play but given the essential challenge of the development dynamic, are not other types of thesauri also required to safeguard and highlight this dynamism?

Should not complementary thesauri be designed using verbs (processes) as categories. and emphasizing the relationship between such processess? it is not sufficient to argue that the noun  "development" implies a "development process" or "to develop". A noun signifies a process deprived of its essential dynamic.

Thesauri using "to develop" as a term would raise many interesting questions, which the static development" at present obscures. The widespread failure of "development" and the prevalence of "maldevelopment" may at least partly be due to a failure to order information in a more dynamic mode.

Bias 2: Low-Context Bias Associated with Western Science

Given the striking contribution of the Western world to the ordering of knowledge in recent centuries, it is easy to forget that there are other approaches to ordering reality which have been favoured in the past, continue to have their advocates, and which may be significant for the future. The scientific method has even been considered a by-product of the indo-European language group. But there are other language groups, especially in the highly populated developing countries. it is too easily assumed that a thesaurus, meaningfully structured to the Western mind, in an adequate vehicle for knowledge for users in non-Western cultures for whom other dimensions may be of greater significance.

David Bohm clarifies the subtle anti-developmental consequences of this bias an follows:

    "As indicated earlier, one of the major defects of the ordinary mode of using language is just its general implication that it is not restricting the world view in any way at all, and that in any case questions of world view have to do only with one's own particular philosophy, rather than with the content and function of our language, or with the way in which we tend to experience the overall reality in which we live. By thus making us believe that our world view is only a relatively unimportant matter, perhaps involving mainly one's personal taste or choice, the ordinary mode of language leads us to fall to give attention to the actual function of the divisive world view that pervades this mode. so that the automatic and habitual operation of our thought and language is then able to project these divisions (in the manner discussed earlier) as if they were actual fragmentary breaks in the nature of  "what is". It is thus essential to be aware of the world view implied in each form of language, and to be watchful and alert, to be ready to see when this world view ceases to fit actual observation and experience. as these are extended beyond certain limits." (7, pp. 46-7)
Whorf and others stress the manner in which languages pre-order reality in unexpected ways. Anthropologist Edward T Hall notes that:

    Also a review of the historical development of taxonomy of living things reveals that, paradoxically, the more Western man classifies, the less useful are his classificatory systems. Folk taxonomies and scientific taxonomies are examples of high-and low-context systems respectively ... modern classification methods provide man with a lot of information that is difficult to integrate into a usable, intelligible pattern. This is a classic example of low-context information. ... The classification system cannot handle the vast numbers now involved. A new paradigm is clearly needed. ... Whichever way we Westerners turn, we find ourselves deeply preoccupied with specifics, to the exclusion of everything else. ... The questions that must be answered are: Where do we go for the overview? Who is putting things together? Who are the experts in high context Integrative systems? Who knows how to make the type of observations necessary to build integrative systems of thought that will tell us where we stand" (8, pp. 122- 123).
Elsewhere Hall notes: "Therefore, as things become more complex, as they inevitably must with fast-evolving, low-context systems, it eventually becomes necessary to turn life and institutions around and move toward the greater stability of the high-context part of the scale as a way of dealing with information overload" (8, p.103).

The effective imposition of indo-European classification schemes on other cultures may therefore not only do violence to their cultural perspectives but may also obstruct both communication to those cultures (knowledge transfer) and communication from them (of the high-context variety rare in Western knowledge systems).

How can high and low-context dimensions be blended together in a development-oriented thesaurus?

Bias 3: Pattern Conservation Bias

Thesauri are usually designed with "spare positions" at which new sub-categories can be added. The healthy "evolution" of the thesaurus over time is then seen as the gradual filling up of these positions. Serious problems arise when there are no longer any spare positions available for new subcategories. Various "fudging" techniques are then used to "squeeze them in".

At no point is there any question of changing the fundamental pattern around which the thesaurus is built. Thesauri are assumed to grow by extension of a pre-defined pattern and not by transformation of that pattern. This conservative bias is a definite obstacle to conceptual advance whenever interdisciplinary subjects become fashionable (e.g. development, environment)

This bias is itself protected and reinforced by the manner in which resources are invested in the documentation systems based on the untransformable thesaurus. The consequence is that if a new pattern appears desirable, an alternative thesaurus has to be designed (usually within a different institutional context, as in the case of UNESCO/SPINES). The new thesaurus, however, tends also to be built with the same pattern conserving bias.

Users are thus confronted with a set of unrelated thesauri whose advocates are seldom concerned by the lack of relationship between them. (This gives rise to what might be called the "politics of the thesauri arena"). This bias is therefore a guarantee of discontinuity and of inter-thesauri hubris - both of which undermine the effective mobilization of conceptual resources for development.

Bias 4: Dysfunctional Bias

Most thesauri are of necessity (given the manual processing tradition) fairly simple structures. They are merely an evolutionary step beyond the list. The main concern is to be able to store and retrieve reasonably wellidentified documents. Unfortunately, this design philosophy is insensitive to functional relationships between the phenomena thus encoded. The fact, for example, that mercury may penetrate through food chains to affect seriously the survival of a bird species is not something that such a thesaurus is designed to highlight (especially in the case of a specialized thesaurus for
chemical compounds). A response might be that this is not the purpose of a thesaurus and that, properly coded, documents reflecting the mercury/ bird relationship could be retrieved.

Whilst this might indeed be the case -- if the user knew how (or why) to phrase the correct question -- there is a major difference between a thesaurus designed to highlight (or even "foresee") such relationships, and one which simply "absorbs" the relevant document and "observes" the relationship. Such relationships are vital to understanding the development process.

Bias 5: Insensitivity to thesaurus implications

Although few would argue that the universe is organized into the categories reflected in a given thesaurus, unfortunately many users are poorly served by the mechanistic category assemblages characteristic of existing thesauri. Because thesauri are the prime concern of high-volume documentation systems, it is easy to forget the needs of those who want information directly relevant to development. Such users may be misled by the structure of existing thesauri and their simplified versions. Or, frustrated by the lack of a relevant thesaurus, they may well have to design their own -- however primitive.

The irresponsibility of those skilled in thesaurus design may be seen in their lack of concern for the following user needs:

    (a) Bookshop layout: Major bookshops, faced with the volume of books, are now reduced to displaying books linearly within a few sections and relying on retrieval by author. There are no non-linear aids to retrieval other than point-of-sale advertising of fashionable items. Sale of books in mass marketing environments ensures the absence of qualified assistants to provide non-linear retrieval advice.
    (b) Agenda design: The link is seldom made between thesaurus design and the construction of an agenda, despite the major importance of the latter for action planning. it is highly probable that many agendas are "bad* thesauri, and many thesauri constitute "bad" agendas (even in development agencies).

    (c) Curricula design: Consider the relation between thesaurus design and the elaboration of a curriculum for a school or university. Despite the developmental significance of curricula, it is highly probable that many curricula are "bad" thesauri, and many thesauri constitute 'bad'

    (d) Organization charts: The organization chart of any institution, including governments, is in effect a thesaurus of action responsibilities. Again it is. highly probable that many such charts do not benefit from the skills of thesaurus construction, and that many thesauri are a poor foundation for the structuring of organizational responsibilities, in response to development issues. This problem also extends to planning and policy formulation. Many thesauri may simply reinforce bad policymaking.

In each of the above examples there is a sense in which the operational context could constitute a 'bad' thesaurus - the "medium becomes the message"-- however good the thesauri used in documentation systems may seem to be.

Bias 6: Avoidance of Top-of-Hierarchy issues

Most of the effort in thesaurus construction is directed to clarify problems within some domains. Little effort, by contrast, is directed toward clarifying relationships between the major hierarchies within which this effort is made. The identification of what constitutes the "top of the hierarchy" appears to be an empirical process influenced by:

  • the pre-determined priorities of the institution commissioning a thesaurus design,
  • the number of digits available in the first position of any code by which the hierarchy is to be ordered,
  • the traditional divisions of the universe which the thesaurus reflects in an essentially passive explanatory mode.
 From this perspective, it is astounding to note the lack of significant difference between the earliest recorded groupings of knowledge some 3000 years ago (9, 10) and recent thesauri such as those generated by UNESCO (11) or the UN Inter-Organization Board for information Systems (12).

From a structural viewpoint there is little to distinguish between them, since both ancient and modern groupings take the form of lists or trees whose mathematical description is very similar. The lack of innovation and experiment is to be contrasted with the extraordinary structural variety in the attempts over the last two centuries to move beyond the original lists of chemical elements (13). Some exceptions are noted below.

From a content viewpoint, there have of course been many innovations. But what remains implicit in thesaurus design is the basis on which major groupings, such as "religion" or "art" are included, downgraded or excluded from a thesaurus which is concerned with "economic and social development".

How is the presence of "art" as one major grouping, to be justified in a thesaurus which contains "science"? How are other major groupings to be recognized? What does the historical development of thesaurus construction reveal about blind-spots in the selection of major domains? On what theoretical ground is it possible to stand in order to predict current blind-spots which might be of vital significance to the development process?

To answer such questions, a functionally-oriented awareness is required. What is it in the way a social group functions which determines the way that group cuts up the field of its perception (and then proceeds to reinforce the subdivision by institutionalizing it In various ways)? Avoiding such questions ensures that any thesaurus will not serve well one or more cultures of this highly diversified planet.

Bias 7: Preference for Adaptive "Maintenance" Thesauri

A recent UNESCO-endorsed report of the Club of Rome entitled No Limits to Learning (14) stresses the importance for society of 'innovative learning" as contrasted with the traditional forms of "maintenance" or "adaptive" learning - particularly if humanity is to preserve and develop its heritage through the present combination of crises.

In this light, it is fair to state that most thesauri are adapted, after the fact, in response to new issues. Every attempt is made to fit new issues into old frameworks which failed to highlight the last crises. New thesauri when the are designed are generally uncreative compromises between the faults of existing thesauri. They do not breakthrough to a new level of significance. it is therefore not surprising that society is ill-equippped to marshall its resources in response to previously unforeseen crises in the development process.

Bias 8: Investment in Rigid, Anti-Experimental Systems

Thesauri tend to be designed in one of two ways, possibly with some overlap between them:

  • the framework is conceived, and existing items are fitted into it, before using the scheme in practice ("top-down"),
  • sample lists of items used in practice, usually by different institutions, are grouped together experimentally for comment and revision ("bottom-up").
Both approaches are maintained completely separate from on-going use of any documentation system by real users. If, and when, the resulting thesaurus is implemented in practice it is difficult to set further experimentation (for several years at least) because of the heavy cost of any such changes. institutions become "locked" into a rapidly aging thesaurus.

The problem seems to lie in the failure to separate control of: (a) documents, (b) document location ("shelf") numbers, (c) machine-readable document (bibliographic) descriptions, (d) thesaurus terms, (e) thesaurus term references (e.g. a "line number" as in a word processor file), (f) classification codes, and (g) classification schemes.

An alternative approach, entirely feasible using computers, is to work with a variable classification code. This is possible if the code (f) is not permanently attached to the document description (c). By using the reference number (e), the code (f) attributed to a thesaurus term (d) can be modified at any time. This means that alternative schemes of classification codes (f) can be envisaged so that the thesaurus terms (d) can be regrouped and edited experimentally and -- whenever desired - the document description (c) can be reordered by computer according to the revised scheme. From a computer viewpoint, this is best done using a permanent document number (b). Clearly there is no reason why a preferred "universal" scheme of codes should not be part of the computer programme "library" of ways of ordering the terms, and in fact several such schemes could be available, without preventing experiments on alternative thesaurus designs. Changing an item in the thesaurus does not therefore involve the usual high cost of physically re-indexing a large number of documents, but only the computer processing cost of changing the classification code linked (electronically) to the "address" of the document.

Such an alternative has already been used by the author to regroup, 3,100 international organizations in terms of their 81,000 links to member countries (15). The country code can be varied to order the information in terms of alternative regional groupings of countries. The same procedure in being used to regroup some 10,000 internationally-oriented bodies by subject [applied from 1982 in the Yearbook of International Organizations, Vol 3. (16). Whilst at this stage the depth of indexing may be unsatisfactory for some purposes, the ability to refine and experiment with the classification scheme introduces a much needed dynamic element Into such endeavours. Clearly such an approach has the additional advantage of providing a more realistic educational tool for those learning about some aspects of the problems of thesaurus design.

Bias 9: Depersonalized Portrayal of Thesauri

Thesauri tend to be portrayed as abstract structures from which subjective personal elements have been eliminated. To ensure implementation, the design of thesauri is limited to a small elite (whose professional status benefits in consequence). In fact, however, as any debate among such elites quickly demonstrates, thesauri are highly personal constructs and (as social acts) can engender very emotional responses. Even from a purely logical point of view, as Francisco Varela demonstrates: "In contrast with what is commonly assumed, a description, when carefully inspected, reveals the properties of the observer" (17). A thesaurus is a description which characterizes the designer (or the designing institutions).

If thesauri embody personal, ideological, cultural, and operational biases in this way, this should be more clearly stated (e.g. in the introduction to any UNESCO thesaurus) together with the implications of that statement. But it also follows that much greater emphasis should be placed on arranging for each user to enjoy the creative advantages of personalizing the thesaurus through which s/he wishes to perceive any data set.

This is especially true given the developmental significance of tramforming one's own thesaurus, as one's perspective matures, rather than being imprisoned in some institutionalized construct -- depersonalization has never enhanced the innovative responses needed at this time. The computer possibilities for doing this have been noted above.

Bias 10: Concealment of Contradictions

The essence of the dramatic situation faced by humanity at this time lies in the conflict between laudable concerns such as economic production and environmental quality, or between communication and the preservation of the uniqueness of different cultures, etc. Whether such polarites are viewed as inherently contradictory or as vitally complementary matters less than the fact that this dynamic feature is totally absent as a structural dimension of thesauri design. The unfortunate exception is that some institutionally inspired thesauri are designed to exclude particular poles when the institution is an advocate of the opposing complementary.

This is especially unfortunate when the institution is obliged to alternate between the polar positions (as in the case of public agencies in a 2-party governmental system).

It is useful to speculate on the advantages of designing into thesauri, not only dyadic, but also triadic, complementarities and those corresponding to greater numbers of set elements (4).

Bias 11: Concealment of Values

In the ongoing debate as to whether science, and especially social science, can be "value-free". it is easy to assume that thesauri (if nothing else) are free of inbuilt value orientations. However, as has been implied above, this is far from true. In fact each decision in the design of a thesaurus is influenced by a set of values which is never rendered explicit (except in the structure of the thesaurus itself). Expressed somewhat differently:

    "it is all too easy for the person who is in full command of a particular behavioural system, such as language (or a thesaurus), to confuse what he can do with a given system, with the unstated rules governing the way the system operates" (Hall, 8, p.88).
When thesauri are compared in this light, some strange emphases become apparent. Subject fields which are included in one thesaurus will be strongly compressed, expanded, or excluded in others, for reasons which are far from obvious. An institutional thesaurus is in fact one of the best indicators of the prejudices of an organization.

This situation cannot be avoided, but a more creative response is possible if a user can "personalize" the thesaurus by expanding, collapsing or reallocating categories at will (as suggested under Bias 8), and then to compare them with those of alternative value perspectives. It is even useful to reflect on the possibility of computer generated "distorsion indicators" (when a user suppresses all environmental categories from an industry thesaurus, for example).

Why is it that no thesauri have been produced with values as categories -- or were these the "celestial" frameworks of the medieval period which are made to appear ridiculous by the currently fashionable noun frameworks? As suggested above, modern value thesauri should be possible and would seem to be a vital support for development as an essentially value governed process - and a corrective to some present excesses. On this point, Hall states:

    "In English, when a man says, 'It rained last night', there is no way of knowing how he arrived at that conclusion, or if he is even telling the truth, whereas a Hopi cannot talk about the rain at all without signifying the nature of his relatedness to the event -- firsthand experience, inference, or hearsay" (8, p.87).
A thesaurus using the simple category "rain" would presumable be meaningless to a Hopi. Experience suggests that increasingly the use of categories like "development" are relatively meaningless unless the values associated with it are rendered explicit.

Bias 12: Preference for Simplistic List Structures

As noted above, most thesauri are a form of nested list structures which is one of the most simple structurees in the range explored by man, both in the arts and in the sciences. One response to this has been to abandon, more or less completely, dependence on a thesaurus in favour of associative structures.

This possibility is encouraged by the power of computer text analysis on data bases, which leave it to the user to order the data into any hierarchies desired - a form of conceptual "anarchy" in reaction to the "imperialism" of list structures. A list does not order the relationships between its elements except in relation to nested sublists or in the case of a list in series form. This does not imply that such relationships are lacking, merely that they cannot be reflected in the list form. Note that a list is. in fact a series of "points", but it is not necessary to conceive of it as such. The points could be represented as areas on a surface. It is only in the matrix that the manner in which the total area is cut up becomes explicit.

An advocated by Ingetraut Dahlberg (18), for example, the matrix is an important step beyond the list. It is important because of the extra dimension of order imposed upon the categories. It is worth noting that a first attempt at this which bears a remarkable structural resemblance to one form of the periodic table of chemical elements (13) seems to have been a renaissance "Torre della Sapienza" (19).

As noted in an earlier paper (20, p.292):

    "The cells of a matrix may be thought of as subareas of the area representing the totality that the matrix attempts to reflect. The subareas are, of course, positioned with respect ---to column and row commonalities. It is now interesting to ask why the area is bounded in such a limiting manner, for the rectangular or square form is one of the simplest. It provides a (paned) "'window" through which the totality may be perceived. But it raises questions about the "wall" in which the window is set and the position of the observer in relation to the observed on the other side of the window.

    Now to the extent that the matrix is complete in its coverage, there really should not be any "wall". The matrix should in such cases in effect "wrap around" the observer; all is window and nothing is implicit, unexplicated, or excluded. If this is not so, then the wall should be conceived as wrapping around the observer, possibly with other windows corresponding to other partial views of the external totality to which the observer may turn his attention. From this point of view the conventional two-dimensional matrix raises the question of the conceptual significance of crossing the encompassing boundary. it seems irrational and unmeaningful because the wall is unrecognized. There is almost a flavor of danger of "falling over the edge", as sailors feared with the early 'flat earth' models. "

If it is assumed that the matrix is complete, then it should be possible to represent it without such an arbitrary external boundary. if the external boundary is eliminated, then the matrix takes the form of a closed surface "wrapped around" the observer. The Torre della Sapienza mentioned above was in fact associated with the unique study room of Francesco di Medici in which each surface represented a category (although not necessarily a noun) (21). But by what procedure can a two- dimensional matrix be so transformed and to what does it give rise?

Again referring to the earlier paper (20, pp. 292-3):

     "Consider a two-by-two matrix. The simplest symmetrical figure that retains the same number of areas is the tetrahedron. it provides four "windows" on the external universe for any observer positioned within. The continuity of surface area of the three dimensional figure emphasizes any functional continuity between the aspects associated with the individual subareas or facets (the "panes"). But at the same time. it draws attention to the discontinuities between the areas associated with the edges. They are not smooth transitions but are marked by sharp angles. It may then be asked (if reality is continuous in contrast to our conceptions thereof) whether such a representation suggests others that would reflect a lesser degree of discontinuity between aspects. And indeed there are, for the greater the number of symmetrically disposed surface areas ("panes"), the larger the angle between adjacent areas and the closer the approximation to a continuous surface namely, a spheroid.
    However, the greater the number of distinct areas (whatever they signify), the more difficult it is to comprehend the totality with any precision. The patterning of the surface area may be readily scanned, but it is only through the "distorted discontinuities" of the simpler and most unspherical figures that it may be grasped to any degree (e.g., those corresponding to the simpler matrixes). A compromise may be considered, however. Even a tetrahedron may be projected onto a circumscribed sphere. This cuts up the surface of the sphere into four (sphericallly) triangular areas. More complex figures would, of course, result in more complex patterns on the surface of the sphere."
The challenge is to maintain continuity, but the discontinulties between extant conceptual frameworks suggest that any such goal is idealistic. "Disturbing" factors, and an indicator of conceptual dynamics, are: unequal cell development, gaps, and unrecognized zones (i.e. "wall space" within which the original matrixes were set).

Further investigation of the possibility of introducing non-linear curvature into the traditionally planar preoccupations of thesaurus design could well provide clues to a new level of macro-ordering which is hospitable to a variety of linearlplanar thesauri but nevertheless establishes valuable links between them.

Bias 13: Exclusion of Uncodeable Dimensions

It is easy to argue that thesaurus design should be restricted in a concern for categories which can be embodied in an extended list structure. But, given the present vigorous discussion about right and left-hemisphere approaches to knowledge, it is legitimate to ask whether such thesauri are not simply artefacts of the left-hemisphere analytical mind, and as such are functionally incomplete. This however begs the question as to how righthemisphere holistic dimensions are to be introduced, without doing violence both to their very nature and to the preservation of the distinctions vital to the hard-won achievements of left-hemisphere thought.

It has been assumed that this is not possible because of the inherently analytic nature of the thesaurus structure. But as the previous section suggests, macro-ordering possiblitities may be introduced which give a holistic dimension. The question is whether these must necessarily be linear (left-hemisphere analytical) forms of ordering or whether non-linear (right-hemisphere) forms can be introduced. Such a step would do much to retrieve thesauri from their somewhat isolated "archival" function in society, as well as establishing a bridge to the vital philosophical concern for the integrative, paradoxical, non-rational relationship between complementaries and opposites. In this connection, it is much to be regretted that one of the most reknowned Eastern philosophers concerned with this matter, namely Lao Tse, did not also leave a record of his reflections as keeper of the Chinese imperial archives in the sixth century B.C.

In the light of earlier arguments (4), it may be possible to introduce such new dimensions at the macro-level so that they do not affect the analytical detail which is the present focus of thesaurus design. it is possible that thesauri will reach a new threshold of maturity and relevance to human and social development once this is achieved.

Bias 14: Mechanistic Concept of Thesaurus integration

Current approaches to thesaurus integration are overly simplistic given the range of structures which man has now explored conceptually.

As argued in an earlier paper (23): there are two extremes in the conventional approach to "integration":

  • "agglomerative": in this case alternative thesauri are conceived as co-existing in such a way that their incompatible features do not result in undesirable conflict between them,
  • "fusion": in this case, deliberate efforts are made to reconcile the apparentl incompatible features of the thesauri, such that a new transcendent thesaurus emerges to replace them. This may be achieved by excluding some thesauri which cannot be incorporated in this way. Fusion may only be "house tidying" with compatible thesauri.
The first approach tends to be unsatisfactory in an increasingly complex society in which undesirable conflict does result from incompatibilitles between thesauri. The second tends to be unsatisfactory, either because of conflict arising from what is excluded, or because such fusion is quickly perceived as a constraint on further development if the thesaurus is successfully implemented. The more successful it is, the more its proponents will resist any further reconceptualization. They do not acknowledge their limitations, the need for their limitations, and the need for their eventual demise. They are conceived as a "final solution" detached from the processes which brought them (temporarily) into being.

Much richer approaches to thesaurus integration emerge from, and are necessitated by, such varied domains as ecosystem integration, "oscillatory" integration in multi-party political systems, education, strategy, etc. Any organic form of integration which matches the dynamism of real-world phi nomena is perhaps necessarily oscillatory. Surprisingly, perhaps, there in fact much to be learnt from the theory and philosophy of music as guide to further investigation.It is refreshing to note how this possibility emerges from reflections on the non-Western 4,000 year-old chanted hymn of the Rg Veda of the indian tradition. A careful exploration of this wor by a philosopher, Antonio de Nicolas (24), using the non-Boolean logic of quantum mechanics (25) opens up valuable approaches to integration. The unique feature of the approach is that it is grounded in tone and the shifting relationships between tones. it is through the pattern of musical tone that the significance of the Rg Veda is found.

    "Therefore, from a linguistic and cultural perspective, we have to be aware that we are dealing with a language where tonal. and arithmetical relations establish the epistemological invariances ... Language grounded in music is grounded thereby on context dependency; any tone can have any possible relation to other tones, and the shift from one tone to another, which alone makes melody possible, Is a shift in perspective which the singer himself embodies. Any perspective (tone) must be "sacrificed" for a new one to come into being; the song is a radical activity which requires innovation while maintaining continuity, and the "world" is the creation of the singer, who shares Its dimensions with the song" (24, p.57)

Of the greatest interest is the link made by de Nicolas with P.A. Heelan's concern with "The logic of changing classificatory frameworks" (25) in terms of the conceptual freedom of quantum logic -- which is in complete contrast to the essentially mechanistic structure of conventional thesauri. It is difficult to imagine that significant breakthroughs would not emerge from investigation of such leads in terms of thesaurus design.


This paper is necessarily far from complete but hopefully will prove a stimulus for discussion.

The biases identified are an attempt to give form to the underlying concern that thesaurus design is at present largely counter-productive in terms of the development of society, especially in the manner in which it reinforces, rather than alleviates, the trend towards social fragmentation. As David Bohm indicates:

    "As has been indicated, however, men who are guided by such a fragmentary self-world view cannot, in the long run, do other than to try in their actions to break themselves and the world into piecess, corresponding to their general mode of thinking. Since, in the first instance, fragmentation is an attempt to extend the analysis of the world into separate parts beyond the domain in which to do this is apprpriate, it is in effect an attempt to divide what is really indivisible. In the next step such an attempt will lead us also to try to unite what is not really unitable. This can be seen especially clearly In terms of groupings of people in society (political, economic, religious, etc). The very act of forming such a group tends to create a sense of division and separation of the members from the rest of the world but, because the members are really connected with the whole, this cannot work. Each member has in fact a somewhat different connection, and sooner or later this shows itself an a difference between him and other members of the group. Whenever men divide themselves from the whole of society and attempt to unite by identification within a group It is clear that the group must eventually develop internal strife, which leads to a breakdown of its unity. Likewise when men try to separate some aspect of nature in their practical, technical work, a at~ state of contradiction and disunity will develop. The same sort of thing will happen to the individual when he tries to separate himself from society. True unity in the individual and between man and nature as wen as between man and man can arise only in a form of action that does not attempt to fragment the whole of reality" (7, pp. 15-16)
Although primarily concerned with order as opposed to classification, Bohm's work may be usefully seen as going a step beyond that of Heelan (25) and C A Hooker (26), since all three are concerned with the implications of advances in theoretical physics. Such investigations go to the root of the question of the relationship between a thesaurus as a conceptually ordered whole and the nature of the whole which is supposedly ordered by it. This relationship can be considered irreleveant except when the thesaurus is supposed to facilitate the development of the whole. as is the case in society. in such circumstances, the degree of integration or wholeness of the thesaurus is crucial to its effectiveness. Following Bohm, if perceived reality can be considered as in essence a set of forms in an underlying universal movement or process, then how can knowledge be considered in the same manner? (7, p.xii). And does not such isomorphism have implications for thesaurus design?

Only a view of knowledge as an integral part of the total flux of processes may lead to a more harmonious and orderly approach to life as a whole rather than a static and fragmentary view, which does not treat knowledge as a process, and which splits knowledge off from the rest of reality (7, p.63). The latter view brings about a thoroughgoing confusion that tends to permeate every phase of life, and ultimately makes Impossible the solution of individual and social problems (7, p.27). it may well be asked whether those involved in thesaurus design sense any responsibilitly for reflecting the dynamic wholeness of reality, as opposed to providing an efficient "warehouse parts-list'"of its currently recognized components.

Would it not be beneficial to consider the need for, and the possibility of, totally different kinds of thesaurus design philosophy which would reconcile (in a creative, dynamic manner) the relationship between structured and associative approaches to ordering knowledge? The paper is also a plea
to enrich such investigations with insights from non-Western design in the traditional libraries of China and Japan? (cf.27).

Finally an apology for a basic inconsistency In this paper: Since the list of biases constitutes a primitive thesaurus, it would have been preferable (given the argument of this paper) to structure each bias as a verb in order to shift the whole discussion into a more dynamic mode.
