Abstract

An important aspect of information retrieval systems is domain independence, where the subject of the information is not restricted to certain domains of knowledge. This should be able to represent any topic and although the text representation does not involve any semantic knowledge, lexical and syntactic analysis of the text allows the representation to remain domain independent. Reports research at Dublin City University, Ireland, which concentrates on the lexical and syntactic levels of natural language analysis and describes a domain independent automatic information retrieval system which accesses a very large database of newspaper text from the Wall Street Journal. The system represents the text in the form of syntax trees, and these trees are used in the matching process. Reports early results from the stuyd

Abstract

Describes correspondence between linguistics and information retrieval. Notes relevant ideas of linguistics which are useful for information retrieval, particularly at the levels of semantics and syntax. Demonstrates that the conceptual model of Ranganathan based on canons, postulates and pronciples contains the principles expressed by other scholars in the field of information retrieval. Implements Ranganathan's conceptual models in information retrieval tools, using PRECIS as an example. Concludes the Ranganathan models contain all the germinal ideas to meet the challenges of modern technology

Abstract

A method (HICLAS, DeBoeck & Rosenberg, 1988) for studying the internal structure of semantic concepts is presented. The proposed method reveals the internal structure of the extension as well as the intesion of a concept, together with a correspondence relation that shows the mutual dependence of both structures. Its use is illustrated with the analysis of simple concepts (e.g. sports) and conjunctive concepts (e.g. birds that are also pets). The underlying structure that is revealed can be interpreted as a differentiation of the simple concepts studied and for conjunctive concepts the proposed method is able to extract non-inherited and emergent features (Hampton, 1988)

Abstract

Argumentation consists of representation of the basic structuralist concepts of language/semiotic as a two-level form, as a form of expression and here especially form of content, and of application of these concepts to the phenomena of the representation of the contents of documents. On the basis of argumentation the paper questions the notion of "organizing knowledge", is it, or in what sense it is possible to organize knowledge. The paper bings out some reservations to viewing content representation as organizing knowledge in a strong sense and suggests that instead could be used a notion of (meta)documentation, characterized as communication concerning documents

Abstract

Discusses the importance of the theories and principles of linguistics to the organization of information. Infolinguistics studies information or knowledge using linguistics as a representation mechanism. Theoretical studies of search languages and index languages require a theoretical framework provided by the interdisciplinary approach of infolinguistics which is a blend of cognitive psychology, linguistics and information science. Discusses how infolinguistics can contribute to information retrieval using both computer and manual application of grammatical theories

Abstract

Content analysis, restricted within the limits of written textual documents (WTDCA), is a field which is greatly in need of extensive interdisciplinary research. This would clarify certain concepts, especially those concerned with 'text', as a new central nucleus of semiotic research, and 'content', or the informative power of text. The objective reality (syntax) of the written document should be, in the cognitve process that all content analysis entails, interpreted (semantically and pragmatically) in an intersubjective manner with regard to the context, the analyst's knowledge base and the documentary objectives. The contributions of sociolinguistics (textual), logic (formal) and psychology (cognitive) are fundamental to the conduct of these activities. The criteria used to validate the results obtained complete the necessary conceptual reference panorama

Abstract

Argues that the integration of computational psycholinguistics can improve corporate communication, and thus become a new strategic tool. An electronic dictionary was created of basic, neutral and negative connotations for nouns, verbs and adjectives appearing in press releases and other communication media, which can be updated with client specific words. The focus on negative messages has the objective of detecting who, why and how publics are criticized, to learn from the vocabulary of opinion leaders and to improve issues management proactively. Suggests a new form of analysis called 'computational linguistic context analysis' (CLCA) by analyzing nominal groups of negative words, rather than monitoring content analysis in the traditional way. Concludes that CLCA can be used to analyze large quantities of press cuttings about a company and could, theoretically, be used to analyze the structure, language and style of a particular journalist to whom it is planned to send a press release or article

Abstract

Examines areas in which linguistics in particular and the study of language in general have provided useful insight into specific artificial intelligence areas besides the computational linguistics one. Discusses studies in these areas and argues that these links should be further and more deliberately explored since they have changes of leading the way towards a fruitful integration between the formal and humanistic sciences
