Research on Knowledge Extraction and Visualization in Knowledge Retrieve

In order to adapt to the development tendency of knowledge organization and resolve the problem about the low efficiency of information retrieve, knowledge retrieve as a new retrieval theory is proposed. Based on the knowledge organization, it realizes the intelligent retrieve of knowledge correlation and concept semantic retrieve. It synthetically applies many new theories and technologies, such as the information science, artificial intelligence, cognitive science and linguistics. This paper mainly discusses the realizing mechanism of knowledge retrieve based on knowledge extraction and visualization technology.
