Ontology-based Drug Product Information Extraction System

摘要

Along with Internet and Infobahn is springing up, it has become an important problem that how to catch the interesting information exactly and rapidly in drug ocean. Information Extraction (IE) is a new information management technology: basing on pre-definition template, it extracts special information from semi-structured data and unstructured data. A new approach to extracting drug product information from normal document based on application ontology is presented in this paper. In the paper, we analyze the system architecture, the taxonomy of information extraction, the key technology and weighing measure of information extraction, and introduce the main frame of the system and describe how to design and implement main modules. The results of IE experiment indicate ontology-based drug information extraction system can improve the F-measure which is reflection of recall and precision.
