    Abstract
    Given the phenomena of growth and diversification which affect both text databases and their users, it is essential to reflect on the nature of textual information and its representation within the very particular framework of interactive retrieval systems. The latter aim to correlate two types of conceptual structures, that of the user and that of the text, by way of a third structure - the interface. A typology of levels, of representation is proposed (typographical, lexical, statistical, linguistic, semiotic, and pragmatic). These representations, obtained by means of a multiplicity of strategies (intra-sentence, intratextual, intertextual) applied to different units of information and interrelated, render the interaction between diverse users and the database more flexible and more adaptable

    Abstract
    Presents research in which 4 term weigthing schemes were used to detect information rich passages in texts and the results compared. Demonstrates that word categories and frequency derived weights have a close correlation but that weighting according to the first mention theory or the cue method shows no correlation with frequency based weights

    Abstract
    Since most popular commercialized systems for full text retrieval are designed with full text scaning and Boolean logic query mode, these systems use an oversimplified relationship between the indexing form and the content of document. Reports the use of Singular Value Decomposition (SVD) to develop a Cluster Indexing Model (CIM) based on a Vector Space Model (VSM) in orer to explore the index theory of cluster indexing for chinese full text documents. From a series of experiments, it was found that the indexing performance of CIM is better than traditional VSM, and has almost equivalent effectiveness of the authority control of index terms
