- Abstract
- Document representations for text classification are typically based on the classical Bag-Of-Words paradigm. This approach comes with deficiencies that motivate the integration of features on a higher semantic level than single words. In this paper we propose an enhancement of the classical document representation through concepts extracted from background knowledge. Boosting is used for actual classification. Experimental evaluations on two well known text corpora support our approach through consistent improvement of the results.

- Abstract
- Discusses the importance of classificatory language and research, and identifies major trends in classification development. Looks at ways of testing the quality of representation in classification systems, highlighting a number of basic research fronts. Notes efforts towards the development of a science of classification, beginning with those of Ranganathan. Examines the problems of keeping classification schemes up to date, and the usefulness of classification theory in knowledge organization. Also discusses categorization at generic levels; developments and objectives in the teaching and learning of classification; and future directions for classification research

- Abstract
- A new document representation model is presented in this paper. This model is based on the idea of representing a document by two or more pictures of the document taken from different perspectives. It is shown that by applying the stereo representation model, enhanced textual retrieval performance is achieved because the new model improves the capability of capturing individual features of the document. Experiments have been conducted on two standard corpora, TIME and ADI, using the standard term vector method and the latent semantic indexing (LSI) method based upon both the stereo representation model and the traditional representation model. Statistical t-tests on the experimental results have convincingly illustrated that these methods achieve significant improvements in retrieval performances with the stereo representation model over those with the traditional representation model.

- Abstract
- This paper presents an abstract formalization of the notion of "facets". Facets are relational structures of units, relations and other facets selected for a certain purpose. Facets can be used to structure large knowledge representation systems into a hierarchical arrangement of consistent and independent subsystems (facets) that facilitate flexibility and combinations of different viewpoints or aspects. This paper describes the basic notions, facet characteristics and construction mechanisms. It then explicates the theory in an example of a faceted information retrieval system (FaIR)

- Abstract
- This paper describes to construct faceted ontologies for domain modeling. Building upon the faceted theory of S.R. Ranganathan (1967), the paper intends to address the faceted classification approach applied to build domain ontologies. As classificatory ontologies are employed to represent the relationships of entities and objects on the web, the faceted approach helps to analyze domain representation in an effective way for modeling. Based on this perspective, an ontology of the music domain has been analyzed that would serve as a case study.

- Abstract
- Semantic networks produced from human data have statistical properties that cannot be easily captured by spatial representations. We explore a probabilistic approach to semantic representation that explicitly models the probability with which words occurin diffrent contexts, and hence captures the probabilistic relationships between words. We show that this representation has statistical properties consistent with the large-scale structure of semantic networks constructed by humans, and trace the origins of these properties.

- Abstract
- An important role of an information system is to provide a representation of a universe of discourse, which reflects its structure and behaviour. An equally imprtant function is to support communication within an organization by structuring and coordinating the actions performed by the organization's agents. In many systems development methods, these different roles are not explicitely separated. Representation techniques appropriate for one role are uncritically applied to another. Proposes a unifying framework based on speech act theory, which reconciles the representation and communication roles of information systems. In particular, shows how communication can be modelled by means of discourses, which are viewed as sequences of events

- Abstract
- The general concern of Bazerman's book Shaping Written Knowledge. The Genre and Activity of the Experimental Article in Science is written knowledge as it is produced by the academy. Bazerman discusses in particular the rhetoric, communicative, and epistemological issues of written knowledge. The article discusses these themes in a library and information science (LIS) perspective in terms of their implications for LIS research. For several reasons, it is argued that this way of scrutinizing into written knowledge ought to be of special interest to LIS research. As an example of a particular field of research in LIS, the article discusses the relationship between indexing theory and written knowledge. Bazerman analyzes written knowledge from a literary point of view. Among other things, it is argued that indexing theory can be seen as part of literary theory in that some of the questions raised by the latter are also raised in indexing theory. Furthermore, it is put forward that the indexer can be considered an author. The indexer produces a text, the document representation, which is the text the user actually meets in the first place. That way, the producer of a document representation is to some extent responsible for the quality of the documents indexed. Having discussed this relationship between written knowledge and LIS research in general and indexing theory in particular, it is concluded that LIS research ought to head toward more humanistic oriented research traditions, if the line of research presented by Bazerman should be considered useful for LIS

- Abstract
- Purpose - The purpose of this paper is to explore the basics of semiotic analysis and concept theory that represent two dominant approaches to knowledge representation, and explore how these approaches are fruitful for knowledge organization. Design/methodology/approach - In particular the semiotic theory formulated by the American philosopher C.S. Peirce and the concept theory formulated by Ingetraut Dahlberg are investigated. The paper compares the differences and similarities between these two theories of knowledge representation. Findings - The semiotic model is a general and unrestricted model of signs and Dahlberg's model is thought from the perspective and demand of better knowledge organization system (KOS) development. It is found that Dahlberg's concept model provides a detailed method for analyzing and representing concepts in a KOS, where semiotics provides the philosophical context for representation. Originality/value - This paper is the first to combine theories of knowledge representation, semiotic and concept theory, within the context of knowledge organization.

- Abstract
- In relation to indexing, one of the chief implications of cognitive epistemology is the necessity for redefining knowledge representation concepts for information filing and retrieval purposes. Such a redefinition involves abandoning the traditional, hierarchical, closed-structure classification model. Considers the following in detail: a semiotic critique of classification principles; Ranganathan's classification theory; Ranganathan and cognitive epistemology; and some reflections on the DDC and the Bliss Bibliographic Classification

- Abstract
- Ontologies may be considered knowledge organization systems since the elements interact in a consistent conceptual structure. Theories of the representation of knowledge domains produce models that include definition, representation units, and semantic relationships that are essential for structuring such domain models. A realist viewpoint is proposed to enhance domain ontologies, as definitions provide structure that reveals not only ontological commitment but also relationships between unit representations.

- Abstract
- This paper is based on the project work carries out by the authors at DRTC. Knowledge representation models are used in building intelligent systems for problem solving. The paper discusses, a frame based knowledge representation model built for automatic indexing. The system assigns POPSI indicators and produces subject strings for titles. The results are given in appendices
