1973
Other Initiatives toward a Concept Inventory- / - Originally appeared in 1973 as part of Toward a Concept Inventory Concept coding schemesThere have been many attempts at isolating and classifying elements of meaning at the root of complex concepts. De Grolier (41) notes that methods and the need for them have been regularly discovered and rediscovered since the time of Leibniz or even earlier. He then states:
De Grolier has summarized the work on classification around the world but only a few initiatives seem to be directly related to this project. Usually the work has been directed towards solving a classification problem in some particular field, which strongly influences the design of the scheme. The following, noted by de Grolier, are of more direct relevance:
2. The ADMINS systemWork has been in progress for some years at the M.I.T. Center for International Studies on the development of very general systems for time shared computer data management (44). An item of data is treated as a sequence of categories of information in n-adic relations applied to a specific entity. N-adic data descriptions for social science propositional inventories are noted as being quite complicated, e.g. 'violence' is 'power' over 'power' over 'well-being'. The ADMINS system makes use of a "calculus of relations" for stating the derivation of a new relation that draws on those already existing, and which yields a new relational record between particular entities. It is in the structuring of the programming language around the relational record and in achieving intimate interaction with many storage levels that this system differs from most procedure languages. 3. Citation indexingThe citation indexing method described by Eugene Garfield (and implemented in the form of the Science Citation Index and the recently initiated Social Science Citation Index) is of great interest to this project if the focus on documents can be replaced by a focus on concepts (45). The traditional philosophy of classification system design implies that individual entities (usually documents) can be treated as though they were independent of one another. This basic fallacy not only results in the loss of important informational links, but it is basically inefficient. Little or no effort is made to establish a possible relationship between the entity being classified and the entities already classified. There are exceptions to this rule, but generally the building-block development of human knowledge is not perceptibly reflected in traditional classification systems. In conventional word indexing systems, the indexers cannot afford the time to establish linkages between concepts. Each addition to the body of knowledge is treated as one of a series of independent events, like molecules of a gas. But the literature is not an "ideal gas" - the molecules interact. Similarly, the body of knowledge, partly embodied in the literature, is composed of highly interrelated elements. It is a heavily cross-linked network. The clearly-visible linkages are those ordinarily provided by authors in the form of explicit citations. Less clearly seen are implicit references as in eponyms and neologisms. Almost invisible linkages exist in the natural language expressions which obscure the relationships, especially to an unskilled observer. Conventional bibliography is essentially a simple listing or inventory of publications which disregards most of the interrelationships between the items in the inventory. In contrast, citation indexing integrates this necessary and useful listing in a huge graph or network. In this graph, each entity (in this case documents) is a node or vertex in a huge multi-dimensional network. BY analogy, this model of the literature (which Garfield considers to be equivalent to man's knowledge) is like a large road map in which the cities and towns share varying degrees of connectivitv. Even the smallest hamlets are nodes on the citation map of science. Garfield refers to previous work of his on this type of historical map (46). The powerful technique illustrated by Figure 7 is reproduced from one of his papers (45). Since each document is an "event" and bears a date, a graphical history may be displayed, but with the important advantage of being able to show the interrelationships among events. This is a legitimate starting point for the historian. There is clearly no technical obstacle to handling conceptual entities in the same manner as documents. This would clearly be of value to both the historical and educational model types. Garfield himself refers to the possibility of having such graphs displayed directly onto a computer-controlled TV screen or plotted onto graph paper by a plotting device. Computers currently plot such graphs on standard line printers as output from the commonly-used PERT programs. Garfield is only concerned with the time or historical dimension as a means of sequencing entities, and only with the citation relationship between such entities. There is no reason, however, why other dimensions and relationships should not be used: geographical, educational, logical, etc., corresponding in fact to more of the model-types listed in an earlier heading. 4. Subject Classification SchemesThere are a wide variety of subject classification schemes for document handling. The Universal Decimal Classification and Dewey systems have become widely used but many other systems exist for specialized subject areas. The most recent international review of these schemes in the UNISIST Study
of the feasibility of a world science information system has this comment to
make:
As the UNISIST extract above acknowledges, UDC is one amongst many classification schemes which are in competition. The tendency for different classifying groups to favour different category breakdowns should be contained and facilitated within an information system and not left to deteriorate into sordid squabbles which do not recognize the value to knowledge advance of alternative views, and a continuing effort at reconceptualization, restructuring and redefinition of knowledge. Also of interest is the UN/OECD Aligned List of Descriptors which has now been developed into a "macrothesaurus". This is primarily oriented around mission-focused topics which emerge in the work of the major intergovernmental agencies concerned with economic and social development. From the perspective of this proposal, the following operations have been blurred together:
When terms are dropped, the reverse procedure affecting the structure of the list must be followed. Each of these steps involves operational and intellectual difficulties which tend to slow down and resist modification. In addition, the List makes great efforts to be flexible by being termoriented. To do this it has had to avoid hierarchical classification of any depth. This choice is not in the interests of those users who need a "deep" classification structure. Originally (1967-68) it was intended that UNISIST should cover the basic natural sciences but arguments were put forward for the inclusion of technology "or at least some of its branches, especially medicine, agriculture, building and construction". Ultimately, "the position of the ICSU/Unesco Central Committee was that UNISIST should devote its primary effort to the basic sciences ... and at the same time be sympathetic to a progressive inclusion of the applied and engineering sciences - and eventually the social sciences - on an equal footing with the former" (UNISIST Report, p. 135-6). No time scale was given. The special problems of social sciences are ignored in this vague intention to broaden UNISIST. Whilst the latter may prove to be a dramatic success in the field of the natural sciences, it is questionable whether the same techniques can be successfully applied to the social sciences without doing violence to the process by which the latter develop. In the natural sciences, invariants in the objective world are represented
by signs which can in most cases be directly and unambiguously attached to the
object in question, to the satisfaction of the natural science community. The
sign for the object and the conceptualization of it are intimately and unambiguously
related. Another sign in another language may be used but the rules of transformation
are clear (the natural language verbiage is another matter, but is less significant).
It is a case of "one sign, one concept, one object". It is therefore possible
to infer that knowledge transfer tends to accompany information transfer. (This
inference may however be very dangerous in the case of non-Indo-European language
users, for whom the "objective" nature of the world may appear less significant).
But any extension of the world science information system, as it is conceived,
to the social sciences would only be of superficial significance if the above
distinctions were not reflected in the design of the system. This is because
in the social sciences, most of the debate concerns the relation between perceptual
invariants detected (by the consensus of a group), signs (selected by the group)
and the associated conceptual meaning - as has been recently pointed out by
Jean Piaget (47):
The natural sciences are therefore primarily interested in the debate on the,
usually tangible, content of categories (which are considered to be relatively
permanent), and the dynamic lies in subdividing the categories and discovering
relationships between their content. Whereas the social sciences, unable to
latch onto an unambiguous content, are primarily interested in the categories
themselves and their interrelationships, and the dynamic lies in reformulating,
reshaping, and regrouping the system of categories in an effort to get closer
to the content. Both natural and social science have conceptual parsimony as
a criterion, whereas the "sciences humaines" are interested in multiplying the
number of possible concepts and increasing their variety. It is clear that the
natural sciences could easily adjust to an arbitrary permanent category hierarchy,
whereas the social sciences would be straight-jacketed and ill-served by
any such system. 5. Concept Dictionaries The outstanding importance of dictionaries in the modern world explains why
some lexicographers are dissatisfied with the mechanical method of arranging
words in alphabetical order, and would prefer to classify them according to
the concepts which they express. One would be mistaken in believing that this
is a recent trend, since one finds tentative systematic vocabularies at Babylon
in the third millennium before Christ. 6. "World Problems" IdentificationThe author is currently engaged in a project co-sponsored by the Union of International Associations, Mankind 2000 and the Center for Integrative Studies. This is an attempt to identify, "register" and describe worldwide problems with a view to the publication of a Yearbook of World Problems (51). (Work to date has established that there might be some 2000-5000). The approach is similar in philosophy to that proposed here for concepts. Classification of problems is seen as a second and distinct phase. A crude model is being used to facilitate data collection. Two other models will be used to plot problem interrelationships. It is hoped to be able to map and plot problem networks. |
