    Abstract
    Describes the design and implementation of TACHIR, a tool for the automatic construction of hypertexts for information retrieval. Through the use of an authoring methodology employing a set of well known information retrieval techniques, TACHIR automatically builds up a hypertext from a document collection. The structure of the hypertext reflects a 3 level conceptual model which enables navigation among documents, index terms, and concepts using automatically determined links. The hypertext is implemented using the HTML language. It can be distributed on different sites and different machines over the Internet, and it can be navigated using WWW interfaces

    Abstract
    This paper presents a probabilistic technique to retrieve passages from texts having a large size or heterogeneous semantic content. The proposed technique is independent on any supporting auxiliary data, such as text structure, topic organization, or pre-defined text segments. A Bayesian framework implements the probabilistic technique. We carried out experiments to compare the probabilistique technique to one based on a text segmentation algorithm. In particular, the probabilistique technique is more effective than, or as effective as the one based on the text segmentation to retrieve small passages. Results show that passage size affects passage retrieval performance. Results do also suggest that text organization and query generality may have an impact on the difference in effectiveness between the two techniques

    Abstract
    Introduces what automatic authoring of a hypertext for information retrieval means. The most difficult part of the automatic construction of a hypertext is the creation of links connecting documents or document fragments that are related. Becaus of this, to many researchers it seemed natural to use information retrieval techniques for this purpose, since information retrieval has always dealt with the construction of relationships between objects mutually relevant. Presents a survey of some of the attempts toward the automatic construction of hypertexts for information retrieval. Identifies and compares scope, advantages and limitations of different approaches. Points out the main and most successful current lines of research
