- Abstract
- Purpose - The purpose of this paper is to introduce a new similarity method to gauge the differences between two subject hierarchical structures. Design/methodology/approach - In the proposed similarity measure, nodes on two hierarchical structures are projected onto a two-dimensional space, respectively, and both structural similarity and subject similarity of nodes are considered in the similarity between the two hierarchical structures. The extent to which the structural similarity impacts on the similarity can be controlled by adjusting a parameter. An experiment was conducted to evaluate soundness of the measure. Eight experts whose research interests were information retrieval and information organization participated in the study. Results from the new measure were compared with results from the experts. Findings - The evaluation shows strong correlations between the results from the new method and the results from the experts. It suggests that the similarity method achieved satisfactory results. Practical implications - Hierarchical structures that are found in subject directories, taxonomies, classification systems, and other classificatory structures play an extremely important role in information organization and information representation. Measuring the similarity between two subject hierarchical structures allows an accurate overarching understanding of the degree to which the two hierarchical structures are similar. Originality/value - Both structural similarity and subject similarity of nodes were considered in the proposed similarity method, and the extent to which the structural similarity impacts on the similarity can be adjusted. In addition, a new evaluation method for a hierarchical structure similarity was presented.

- Abstract
- The different points of views an knowledge representation and organization from various research communities reflect underlying philosophies and paradigms in these communities. This paper reviews differences and relations in knowledge representation and organization and generalizes four paradigms-integrative and disintegrative pragmatism and integrative and disintegrative epistemologism. Examples such as classification, XML schemas, and ontologies are compared based an how they specify concepts, build data models, and encode knowledge organization structures. 1. Introduction Knowledge representation (KR) is a term that several research communities use to refer to somewhat different aspects of the same research area. The artificial intelligence (AI) community considers KR as simply "something to do with writing down, in some language or communications medium, descriptions or pictures that correspond in some salient way to the world or a state of the world" (Duce & Ringland, 1988, p. 3). It emphasizes the ways in which knowledge can be encoded in a computer program (Bench-Capon, 1990). For the library and information science (LIS) community, KR is literally the synonym of knowledge organization, i.e., KR is referred to as the process of organizing knowledge into classifications, thesauri, or subject heading lists. KR has another meaning in LIS: it "encompasses every type and method of indexing, abstracting, cataloguing, classification, records management, bibliography and the creation of textual or bibliographic databases for information retrieval" (Anderson, 1996, p. 336). Adding the social dimension to knowledge organization, Hjoerland (1997) states that knowledge is a part of human activities and tied to the division of labor in society, which should be the primary organization of knowledge. Knowledge organization in LIS is secondary or derived, because knowledge is organized in learned institutions and publications. These different points of views an KR suggest that an essential difference in the understanding of KR between both AI and LIS lies in the source of representationwhether KR targets human activities or derivatives (knowledge produced) from human activities. This difference also decides their difference in purpose-in AI KR is mainly computer-application oriented or pragmatic and the result of representation is used to support decisions an human activities, while in LIS KR is conceptually oriented or abstract and the result of representation is used for access to derivatives from human activities.

- Abstract
- Based on the works of Aristotle, Ramon Lull, I. Kant and the experiences with relationships published in the works of S.R. Ranganathan, E.de Grolier, J. Mills, J.C. Costello, E. Wall, R. Pagès, A. Leroy, P. Braffort, M. Kervégant, J.C. Gardin and J. Farradane, categories and relationships were collected, analyzed, grouped and classified in a triadic way so that a scheme resulted by which 120 relationships could be defined and identified by their positions and their codes. The exercise was meant to create and supply a tool for the replacement of the non-significant relation symbol, the colon, in the UDC by a letter code which could express the actual relationship contained in a classificatory statement. Examples for their application illustrate different cases occuring

- Abstract
- All classifications are based on ideologies and Dewey is marked by its author's origins in 19th century North America. Subsequent revisions indicate changed ways of understanding the world. Section 157 (psycho-pathology) is now included with 616.89 (mental troubles), reflecting the move to a genetic-based approach.

- Abstract
- Reports results of a comparative study of 3 classification schemes: LCC, DDC and NLM Classification to determine their effectiveness in classifying materials on health insurance. Examined 2 hypotheses: that there would be no differences in the scatter of the 3 classification schemes; and that there would be overlap between all 3 schemes but no difference in the classes into which the subject was placed. There was subject scatter in all 3 classification schemes and litlle overlap between the 3 systems

- Abstract
- The idea of sameness is used to gather material in classifications. However, it is also used to separate what is different. Sameness and difference as guiding principles of classification seem obvious but are actually fundamental characteristics specifically related to Western culture. Sameness is not a singular factor, but has the potential to represent multiple characteristics or facets. This article explores the ramifications of which characteristics are used to define classifications and in what order. It explains the primacy of division by discipline, its origins in Western philosophy, and the cultural specificity that results. The Dewey Decimal Classification is used as an example throughout.

- Abstract
- This is the fourth in a series of papers on classification based on phenomena instead of disciplines. Together with types, levels and facets that have been discussed in the previous parts, themes and rhemes are further structural components of such a classification. In a statement or in a longer document, a base theme and several particular themes can be identified. Base theme should be cited first in a classmark, followed by particular themes, each with its own facets. In some cases, rhemes can also be expressed, that is new information provided about a theme, converting an abstract statement ("wolves, affected by cervids") into a claim that some thing actually occurs ("wolves are affected by cervids"). In the Integrative Levels Classification rhemes can be expressed by special deictic classes, including those for actual specimens, anaphoras, unknown values, conjunctions and spans, whole universe, anthropocentric favoured classes, and favoured host classes. These features, together with rules for pronounciation, make a classification of phenomena a true language, that may be suitable for many uses.

- Abstract
- This paper surveys classification research literature, discusses various classification theories, and shows that the focus has traditionally been an establishing a scientific foundation for classification research. This paper argues that a shift has taken place, and suggests that contemporary classification research focus an contextual information as the guide for the design and construction of classification schemes.

- Abstract
- A fascinating, broad-ranging article about classification, knowledge, and how they relate. Hierarchies, trees, paradigms (a two-dimensional classification that can look something like a spreadsheet), and facets are covered, with descriptions of how they work and how they can be used for knowledge discovery and creation. Kwasnick outlines how to make a faceted classification: choose facets, develop facets, analyze entities using the facets, and make a citation order. Facets are useful for many reasons: they do not require complete knowledge of the entire body of material; they are hospitable, flexible, and expressive; they do not require a rigid background theory; they can mix theoretical structures and models; and they allow users to view things from many perspectives. Facets do have faults: it can be hard to pick the right ones; it is hard to show relations between them; and it is difficult to visualize them. The coverage of the other methods is equally thorough and there is much to consider for anyone putting a classification on the web.
