Abstract

This paper examnines various isues that arise in establishing a theoretical basis for an experimental fiction analysis system. It analyzes the warrants of fiction and of works about fiction. From this analysis, it derives classificatory requirements for a fiction system. Classificatory techniques that may contribute to the specification of data elements in fiction are suggested

Abstract

Examines the goals of bibliographic control, subject analysis and their relationship for audiovisual materials in general and multipart videotape recordings in particular. Concludes that intellectual access to multipart works is not adequately provided for when these materials are catalogues in collective set records. An alternative is to catalogue the parts separately. This method increases intellectual access by providing more detailed descriptive notes and subject analysis. As evidenced by the large number of records in the national database for parts of multipart videos, cataloguers have made the intellectual content of multipart videos more accessible by cataloguing the parts separately rather than collectively. This reverses the traditional cataloguing process to begin with subject analysis, resulting in the intellectual content of these materials driving the bibliographic description. Suggests ways of determining when multipart videos are best catalogued as sets or separately

Abstract

The indexing process consists of the comprehension of the document to be indexed, followed by the production of a set of index terms. Differences between academic indexing and back-of-the-book indexing are discussed. Text comprehension is a branch of human information processing, and it is argued that the model of text comprehension and production debeloped by van Dijk and Kintsch can form the basis for a cognitive process model of indexing. Strategies for testing such a model are suggested

Abstract

This article presents a theoretical investigation of the concept of 'subject' or 'subject matter' in library and information science. Most conceptions of 'subject' in the literature are not explicit but implicit. Various indexing and classification theories, including automatic indexing and citation indexing, have their own more or less implicit concepts of subject. This fact puts the emphasis on making the implicit theorie of 'subject matter' explicit as the first step. ... The different conceptions of 'subject' can therefore be classified into epistemological positions, e.g. 'subjective idealism' (or the empiric/positivistic viewpoint), 'objective idealism' (the rationalistic viewpoint), 'pragmatism' and 'materialism/realism'. The third and final step is to propose a new theory of subject matter based on an explicit theory of knowledge. In this article this is done from the point of view of a realistic/materialistic epistemology. From this standpoint the subject of a document is defined as the epistemological potentials of that document

Abstract

The training of librarians in content analysis undergoes influences resulting both from the realities existing in the various application fields and from technological innovations. The present contribution attempts to identify components of such training that are necessary for a future-oriented instruction, and it stresses the importance of furnishing a sound theoretical basis, especially in the light of technological developments. Purpose of the training is to provide the foundation for 'action competence' on the part of the students

Abstract

Considers the role of pictures in information communication, comparing the way it conveys information with text. Categorises the purposes of images as conveyors of information: the instructional image, the documentary image, the location image, the graphical representation of numbers, the concepts image, the image making the unseen visible, the image as a surrogate for an object or document, the decorative image, the image as a statement, the strong image and the emotional image. Gives examples of how the value of images is being recognised and of how they can be used well

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

The paper is divided into 3 parts. The 1st develops a framework for evaluating the indexing needs of the humanities with reference to 4 sets of contrasts: user (need)-oriented vs. document-oriented indexing; subject indexing vs. attribute indexing; scientific writing vs. humanistic writing; and topical relevance vs. logical relevance vs. evidential relevance vs. aesthetic relevance. The indexing needs for the humanities range broadly across these contrasts. The 2nd part establishes the centrality of relationships to the communication of indexable matter and examines the advantages and disadvantages of means used for their expression inboth natural languages and indexing languages. The use of relational structure, such as a frame, is shown to represent perhaps the best available option. The 3rd part illustrates where the use of relational structures in humanities indexing would help meet some of the needs previously identified. Although not a panacea, the adoption of frame-based indexing in the humanities might substantially improve the retrieval of its literature

Abstract

Comprehensiveness and consistency in newspaper indexing depend on the effectiveness of subject analysis of the news items. Discusses indexing skills required in order to identify indexable concepts. Describes practical aspects of conceptual analysis, crystalises criteria and methods for the indexing of news stories, and eludicates reasons form providing multiple subject-entries for certain news items. Suggests rules for news analysis and speedy and accurate allocation of subject headings, and illustrates the technique of dealing with complex and diversified news headings reported at intervals. As the headlines do not always indicate the real subject of a news story, the identification of indexable concepts can become arduous and cumbersome. Discusses the methods, skills and capability needed to tackle such problems

Abstract

An examination of some nonbook materials with respect to an aboutness model of indexing leads to the conclusion that there are instances that defy subject indexing. These occur not so much because of the nature of the medium per se but because it is being used for nondocumentary purposes, or, when being used for such purposes, the subject referenced is nonlexical

Abstract

In order to explain how indexers chose their keywords and how their results can differ between each other, focuses on certain properties of the terms rather than on the terms themselves. Bases the study on 4 premises borrowed from research in semiotics, cognitive science, discourse analysis and reading theories. Reports on the methodology used, and some of the findings obtained by comparing properties of indexing terms with the content of titles and abstracts of 844 bibliographic records extracted from a database on environment. Characterizes some tendencies of the special reading which indexing constitutes as a series of properties of the selected or rejected works and explains the differences among several indexers by the porperties toward which they are inclined

Abstract

Document understanding, the interpretation of a document from its image form, is a technology area which benefits greatly from the integration of natural language processing with image processing. Develops a prototype of an Intelligent Document Understanding System (IDUS) which employs several technologies: image processing, optical character recognition, document structure analysis and text understanding in a cooperative fashion. Discusses those areas of research during development of IDUS where it is found that the most benefit from the integration of natural language processing and image processing occured: document structure analysis, OCR correction, and text analysis. Discusses 2 applications which are supported by IDUS: text retrieval and automatic generation of hypertext links

Abstract

Recent research investigated image attributes as reported by participants in describing, sorting, and searching tasks with images and defined 46 specific image attributes which were then organized into 12 major classes. Attributes were also grouped as being 'perceptual' (directly stimulated by visual percepts), 'interpretive' (requiring inference from visual percepts), and 'reactive' (cognitive and affective responses to the images). This research describes the coverage of two image indexing and classification systems and one general classification system in relation to the previous findings and analyzes the extent to which components of these systems are capable of describing the range of image attributes as revealed by the previous research

Abstract

Examines Panofsky's and Barthes's theories of image analysis and reports on a study of criteria for analysis and indexing of images and the different types of user queries used in 15 Danish newspaper image archives. A structured interview method and observation and various categories for subject analysis were used. The results identify a list of the minimum number of elements and led to user typology of 5 categories. The requirement for retrieval may involve combining images in a more visual way with text-based image retrieval

Abstract

The arts, humanities, and social sciences commonly borrow concepts and methods from the sciences, but interdisciplinary borrowing seldom occurs in the opposite direction. Research on narrative discourse is relevant to problems of documentary storage and retrieval, for the arts and humanities in particular, but also for other broad areas of knowledge. This paper views the potential application of narrative discourse analysis to information storage and retrieval problems from 2 perspectives: 1) analysis and comparison of narrative documents in all disciplines may be simplified if fundamental categories that occur in narrative documents can be isolated; and 2) the possibility of subdividing the world of knowledge initially into narrative and non-narrative documents is explored with particular attention to Werlich's work on text types

Abstract

Visual materials represent a significantly different type of communication to textual materials and therefore present distinct challenges for the process of retrieval, especially if by retireval we mean intellectual access to the content of images. This paper outlines the special characteristics of visual materials, focusing on their pontential complexity and subjectivity, and the methods used and explored for gaining access to visual materials as reported in the literature. It concludes that methods of access to visual materials are dominated by the relative mature systems developed for textual materials and that access methods based on visual communication are still largely in the developmental or prototype stage. Although reported research on user requirements in the retrieval of visual information is noticeably lacking, the results of at least one study indicate that the visually-based retrieval methods of structured and unstructered browsing seem to be preferred for visula materials and that effective retrieval methods are ultimately related to characteristics of the enquirer and the visual information sought
