Abstract:
In this work, a novel framework for designing Web Information Retrieval systems with particular reference to semantic search engines is presented. The key idea is to add the semantic dimension to the classical Term-Document Matrix thus having a three-dimensional dataset. This enhancement allows for defining a lexico-semantic user interface where the query process is performed at the conceptual level thanks to the use of a Semantic Lexicon. WordNet Semantic Lexicon is used here as golden ontology for handling polysemy and synonymy, hence it is useful for disambiguating user queries at the semantic level. A layered multi-agent system is employed for supporting the design process. Particular emphasis is given to formal system knowledge representation, the interface layer managing user-system interaction and the markup layer performing the semantic tagging process.
