OFAHIR: “on-the-fly” automatic authoring of hypertexts for information retrieval
Maristella Agosti, Lucio Benfante, Massimo Melucci · 1998
This paper presents the OFAHIR methodology that aims at providing the final user an integrated environment for gathering useful information from a collection of managed digital documents. The methodology is a set of coordinated methods for indexing, querying, clustering, and browsing; this set constitutes an integrated associative retrieval system model . This is the model for a system that enables the user to access a collection of information objects by integrating the processes of querying and browsing; the managed objects are linked making use of semantic associations that are built through indexing and clustering mechanisms. The OFAHIR methodology is the first step towards the definition of a general and comprehensive associative retrieval model for information gathering. Together with the methodology also a system tool that implements it is presented in the paper. This system can work in a World Wide Web environment since the components performing the data retrieval have been implemented according to standard protocols. Through any available Web client a user can pose queries to and/or browse the managed document digital collection. Performance and evaluation aspects are also addressed in the paper, together with aspects that are going to be addressed in the future.
