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...
Along with the rapid popularity of the Internet, crime information on the web is becoming increasingly rampant, and the majority of them are in the form of text. Because a lot of crime information in documents is described through events, event-based semantic technology can be used to study the patterns and trends of web-oriented crimes. In our research project on cyber crime mining, we construct...
Domain knowledge for Web applications is currently being made available as domain ontology with the advent of the semantic Web, in which semantics govern relationships among objects of interest (e. g., commercial items to be purchased in an e-commerce Web site). Our earlier work proposed to integrate semantic information into all phases of the Web usage mining process, for an intelligent semantics-aware...
An expansion model of semantic query based on ontology is proposed for the problem of ldquoexpression differencerdquo and ldquomechanical matchrdquo that usually exists in information retrieval. By using domain knowledge in ontology, retrieval system can improve semantic understanding of retrieval documents, and give the chance to user to put their information request in more nature way (more precise...
The manual design of an ontology usually defines the concepts for the domain, but the individual instances of the concepts are often missing though they are important in using the ontology as a knowledge base. This is due to high cost of the manual construction of individuals. In order to tackle this problem, this paper proposes an automatic method for ontology population. The knowledge source for...
In recent years, the application of ontology has been already toward the diversification under the development of the semantic Web technology. The main application of ontology is information retrieval. With the utilization of ontology, we expect to offer more correct information for users. Although, most of the applications of ontology are information retrieval but they lacks of the interaction with...
