A Logic-Based Tool for Semantic Information Extraction
[chapter]
2006
Lecture Notes in Computer Science
The paper describes HıLεX, a new ASP-based system for the extraction of information from unstructured documents. Unlike previous systems, which are mainly syntactic, HıLεX combines both semantic and syntactic knowledge for a powerful information extraction. In particular, the exploitation of background knowledge, stored in a domain ontology, allows to empower significantly the information extraction mechanisms. HıLεX is founded on a new two-dimensional representation of documents, and heavily
