- Abstract
- Traces the history and development of cognitive research techniques in information science and surveys current research that relies on the cognitive aspect. Examines information systems that make use of the insights of cognitive research, including experimental and proposed systems. Examples include systems that are designed to make appropriate demands on user cognitive processing. Points out that cognitive research in information science has focused primarily on users of information systems and to a lesser extent on information intermediaries. Design initiatives deriving from this research have been directed toward developing information technology that can adapt to the knowledge abilities, and styles of individual users and that make efficient use of the knowledge base and cognitive process of groups of users

- Abstract
- This chapter reviews research and applications in statistical language modeling for information retrieval (IR), which has emerged within the past several years as a new probabilistic framework for describing information retrieval processes. Generally speaking, statistical language modeling, or more simply language modeling (LM), involves estimating a probability distribution that captures statistical regularities of natural language use. Applied to information retrieval, language modeling refers to the problem of estimating the likelihood that a query and a document could have been generated by the same language model, given the language model of the document either with or without a language model of the query. The roots of statistical language modeling date to the beginning of the twentieth century when Markov tried to model letter sequences in works of Russian literature (Manning & Schütze, 1999). Zipf (1929, 1932, 1949, 1965) studied the statistical properties of text and discovered that the frequency of works decays as a Power function of each works rank. However, it was Shannon's (1951) work that inspired later research in this area. In 1951, eager to explore the applications of his newly founded information theory to human language, Shannon used a prediction game involving n-grams to investigate the information content of English text. He evaluated n-gram models' performance by comparing their crossentropy an texts with the true entropy estimated using predictions made by human subjects. For many years, statistical language models have been used primarily for automatic speech recognition. Since 1980, when the first significant language model was proposed (Rosenfeld, 2000), statistical language modeling has become a fundamental component of speech recognition, machine translation, and spelling correction.

- Abstract
- The research literature published in 1991 in the following categories is examined: users and subject searching, subject access in online catalogs, subject cataloging and indexing, information retrieval, thesaurus and indexing approaches, classification, and specialized subjects and materials. The preponderance of the research dealt with improving subject access in online systems. This seems to have been the result of acceptance by many researchers of a number of previously researched hypotheses that, taken together, indicate that improving online systems holds more promise than trying to perfect the processes of subject analysis

- Abstract
- Focuses on the application of parallel processing for the processing of text, primarily documents and document surrogates. Research on parallel processing of text has developed in 2 areas: a hardware approach involving the development of special purpose machines for text processing; and a software approach in which data structures and algorithms are developed for text searching using general purpose parallel processors

- Abstract
- State of the art review of information retrieval techniques viewed in terms of the growing effort to implement concept based retrieval in content based algorithms. Identifies trends in the automation of indexing, retrieval, and the interaction between systems and users. Identifies 3 central issues: ways in which systems describe documents for purposes of information retrieval; ways in which systems compute the degree of match between a given document and the current state of the query; amd what the systems do with the information that they obtain from the users. Looks at information retrieval techniques in terms of: location, navigation; indexing; documents; queries; structures; concepts; matching documents to queries; restoring query structure; algorithms and content versus concepts; formulation of concepts in terms of contents; formulation of concepts with the assistance of the users; complex system codes versus underlying principles; and system evaluation

- Abstract
- State of the art review of methods available for accessing collections of digital images by means of manual and automatic indexing. Distinguishes between concept based indexing, in which images and the objects represented, are manually identified and described in terms of what they are and represent, and content based indexing, in which features of images (such as colours) are automatically identified and extracted. The main discussion is arranged in 6 sections: studies of image systems and their use; approaches to indexing images; image attributes; concept based indexing; content based indexing; and browsing in image retrieval. The performance of current image retrieval systems is largely untested and they still lack an extensive history and tradition of evaluation and standards for assessing performance. Concludes that there is a significant amount of research to be done before image retrieval systems can reach the state of development of text retrieval systems

- Abstract
- International computerized indexing systems for visual materials are discussed. The systems included were among the best in the literature for their time or have significant potential and represent the state of the art in their respective countries. Technologies available for reproducing images are also investigated, highlighting videotex, videodisc, and digital storage. The interfacing of these technologies with each other and with online, postcoordinate retrieval systems could facilitate the ultimate achievement in visual indexing

- Abstract
- State of the art review of relevance as it relates to the behaviour of users seeking and using information rather than in evaluating the performance of information retrieval systems. Views relevance as a manifestation of human information behaviour and excludes works that view relevance only as matching or computational functions of information retrieval systems

- Abstract
- Identifies the interest in questions of classified catalogues generated by the development of on-line catalogues, establishing a difference between 2 large areas: free access to information items in a systematic arrangement and expressing the contents of books by means of notational symbols in a classification system in a local catalogue. Examines the elements and structure of classification systems, the internationally important universal classifications, the procedures for book display and systematic processing in West German public libraries and exhibtion techniques in West German academic libraries. Covers universal and faceted classifications, as well as classification systems in on-line catalogues

- Abstract
- Discusses the human-computer interface for information retrieval and notes that research on human-computer interface design has generated many widely-accepted principles of interface design which should be of interest and value to designers of information retrieval systems. Work on display features such as highlighting, colour, icons, and windows has received considerable attention. research has also focused on how the user interacts with the system, whether by commands, menus, or direct manipulation. Studies of interfaces for information retrieval systems reveal that online searching has emphasised developments of front ends, with some novel uses of graphics. CD-ROM and optical media are characterised by interface diversity, again with some inclusion of graphic interfaces. Online catalogues and full text data bases have provided interesting comparisons of mode of interaction

- Abstract
- Current research on user interfaces to online public access catalogs is reviewed in an attempt to identify research methods and findings applicable to the design of effective user interfaces to online public access catalogs. A broad definition of user interface is employed which includes data structures, in addition to searching and indexing software. The following features of online public access catalogs are discussed: the demonstration of relationships between records, the provision of entry vocabularies, the arrangement of multiple entries on the screen, the provision of access points, the display of single records, and the division of the catalog into separate files or indexes. For each feature, user studies and other research on online public access catalogs are reviewed and those findings summarized which provide insight into user needs concerning that particular feature; issues are identified and directions for further research are suggested. Implications for cataloging codes and standards and system design are discussed
