Abstract
The huge amount of medical data in the Internet requires intelligent tools to retrieve and process medical information. In this paper, we introduce GINY, a computer system that integrates several procedures to deal with the structured, semi-structured and non-structured documents that can be found in the Internet. From our ontology that describes a medical concept and its properties, the system retrieves related web pages in the web, analyzes the contents of the pages, and organizes the extracted data in a Relational Data Base (RDB) or a Resource Description Framework (RDF). The stages of the process can be made partially or totally automatic.
