Abstract

Five controlled vocabularies currently used for content representation in collections of non art moving images were examined to determine their level of conceptual compatibility. Methods borrowed from previous research in the area of indexing language compatibility were used. Quantitative data and qualitative observations allowed us to estimate more precisely and realistically the actual degree of conceptual redundancy in these indexing languages. It was found that the conceptual overlap is high enough to justify the pursuit of research and development work an a common basic indexing and access language that could be used to name objects, events, categories of persons, and relations most frequently depicted in non art moving image collections.

Abstract

This paper examines whether a concept's hierarchical level affects the likelihood of its universality across schemes for knowledge representation and knowledge organization. Empirical data an equivalents are drawn from a bilingual thesaurus, a pair of biomedical vocabularies, and two ontologies. Conceptual equivalence across resources occurs significantly more often at the basic level than at subordinate or superordinate levels. Attempts to integrate knowledge representation or knowledge organization tools should concentrate an establishing equivalences at the basic level. 1. Rationale The degree of success attainable in the integration of multiple knowledge representation systems or knowledge organization schemes is constrained by limitations an the universality of human conceptual systems. For example, human languages do not all lexicalize the same set of concepts; nor do they structure (quasi-)equivalent concepts in the same relational patterns (Riesthuis, 2001). As a consequence, even multilingual thesauri designed from the outset from the perspective of multiple languages may routinely include situations where corresponding terms are not truly equivalent (Hudon, 1997, 2001). Intuitively, where inexactness and partialness in equivalence mappings across knowledge representation schemes and knowledge organizations schemes exist, a more difficult retrieval scenario arises than where equivalence mappings reflect full and exact conceptual matches. The question we address in this paper is whether a concept's hierarchical level af ects the likelihood of its universality/full equivalence across schemes for knowledge representation and knowledge organization. Cognitive science research has shown that one particular hierarchical level-called the basic level--enjoys a privileged status (Brown, 1958; Rosch et al., 1976). Our underlying hypothesis is that concepts at the basic level (e.g., apple, shoe, chair) are more likely to match across knowledge representation schemes and knowledge organization schemes than concepts at the superordinate (e.g., fruit, footwear, furniture) or subordinate (e.g., Granny Smith, sneaker, recliner) levels. This hypothesis is consistent with ethnobiological data showing that folk classifications of flora are more likely to agree at the basic level than at superordinate or subordinate levels (Berlin, 1992).

Abstract

Results of a project focusing on six Web-based collections in education. Our analysis of homegrown classification structures considers three dimensions. "Structure" is described through quantitative data (e.g. Number of main categories, Number of hierarchical levels, etc.). "Logic" concentrates on two aspects of the subdividing process: division principle, and type of hierarchical relation. "Semantics" relates to concepts and their representation in the form of terms. In our sample, the classification structures are hierarchical, not overly complex and not very specific. The choice, arrangement and sequence of classes are logical. Conceptual and terminological inconsistencies are due to significant gaps in conceptual coverage and lack of terminological control.
