Medical data extraction and organization from the Internet

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 an 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.
