Abstract


The information age and the rapid popularization and application of the Internet makes the save a broad array of data and information on the Internet . Mainstream information retrieval technology is mainly based on keyword search, the specific method is focused on the study of mathematical algorithms , and the relative neglect of the importance of semantic retrieval and semantic reasoning . Widespread on the Internet message format heterogeneity, multiplicity and the lack of information between the semantics of information and are not unified, to people in search of information , extraction , which means that , to explain and defend the cause great inconvenience . To solve this problem , it is knowledge retrieval of this new type of intelligent information retrieval method . Knowledge retrieval , the use of knowledge management and knowledge organization on the basis of the analysis contains information recording knowledge and knowledge associated technology, intelligent query based on semantic understanding . The knowledge retrieval emphasize knowledge-based semantic matching . Semantic retrieval is one of the keys to achieve knowledge retrieval , semantic retrieval can not be separated from the calculation of semantic similarity . The semantic reasoning Knowledge Retrieval another key . Semantic reasoning in the knowledge retrieval include two aspects, namely the application of logic reasoning tests to ensure logical consistency and correctness of the knowledge described in the ontology structure , and application reasoning found implicit semantic association so that the semantic relationship of the body more complete.
