— This paper addresses some particular issues related to the difficult task of automatically structuring information available in ill-structured environments, through a distributed hypermedia system like the Web. We present an original approach to this problem, which coordinates different aspects of automatic computation of relations between nodes in(More)
This paper presents HyperMap system to dynamically structure information on the Web. The system is based on a framework resultant from a multi-disciplinary research which is briefly discussed. This paper focuses work done to develop new generation of computational tools able to support the extraction and the discovery of useful information on the Web(More)
This paper addresses some particular issues related to the difficult task of automatic mapping of Web information to help the user to find interesting and unexpected information on the Web. The approach puts together qualitative and quantitative reasoning. The qualitative reasoning is done through a spatial mereotopological calculus since we metaphorically(More)
This work analyses principles and methods relevant to the planning and development of Natural Language Processing (NLP) systems , whose goal is to assist in language learning. Syntax checking based on the HPSG formalism as implemented in the LKB (Linguistic Knowledge Building) system is the main focus. Java language was used to implement a parser that,(More)
