    Abstract
    Natural language processing (NLP) is a powerful technology for the vital tasks of information retrieval (IR) and knowledge discovery (KD) which, in turn, feed the visualization systems of the present and future and enable knowledge workers to focus more of their time on the vital tasks of analysis and prediction

    Abstract
    Gives an overview of a research project which had aimed to: empirically investigate book-index usage behaviours and the extent to which specific print index features affect a user's search for information; and to examine these same features in an electronic environment. Aims to determine the optimum specifications for indexes in electronic texts by gathering evidence from a controlled user study. Presents a subset of results from index use in both print and electronic formats. Suggests a preliminay model representing users' behaviours when using an index and suggests implications for system design

    Abstract
    Part of a larger study which aims to: empirically investigate book-index usage, behaviours, and the extent to which specific print index features affect a user's search for information; and to examine these features in an electronic environment and to determine the optimum specifications for indexes in electronic texts by gathering evidence from a controlled user study. Provides an overview of the research project, focusing on a subset of the results from the study of hard-copy book indexes. Describes observable behaviours of a sample of users when consulting different variations of a hard copy book index. Suggests a preliminary model at 3 levels of abstraction repressing users' behaviours when using a book index

    Abstract
    Describes an alternative method of representation for documents and queries in information retrieval systems to the 2 most common methods: free text, natural language representation and controlled language representation. The alternative method combines the advantage of both traditional approaches and overcomes the difficulties associated with each. The scheme was developed for use with Longman's Dictionary of Contemporary English and uses a computerized version of the dictionary for the automatic generation of summary level semantic representations of each document and query. The system tags each word in a document with the appropriate Subject Field Code (SFC) from the dictionary and the SFCs are summed and normalized to produce a weighted, fixed length vector of the SFC. The search system matches the query SFC vector to the document SFC vectors in the database. The documents are then ranked on the basis of their vector's similarity to the query
