Research and Implementation of Chinese Patent Information Gathering System Based on Domain Ontology

Traditional information gathering systems are mostly keyword-based that are lack of semantic comprehension and analysis ability and can´t guarantee the comprehensiveness and accuracy of information gathering. This paper proposes Chinese patent information gathering model based on domain ontology, which can visualize ontology concept semantic map related to user gathering requirements on the information gathering interface. Users can select more related and professional domain concept to user gathering subjects from ontology concept semantic map, the system may automatically carry out semantic inference and extension to the selected domain concept, and form the normative expansive semantic gathering expression to gather patent information from the related web pages. In order to verify feasibility and effectiveness of the model, this paper selects clothing domain, develops Chinese clothing domain ontology, implements the patent information gathering system based on clothing domain ontology. Experiment results show that the model can greatly improve the comprehensiveness and accuracy of information gathering.
