Research on Semantic Retrieval for Communication Ontology

Seven-step method is used to build the communication domain ontology, and the system uses Jena stored the ontology to the relational database. It Uses ICTCLAS Chinese word segmentation machine to deal with retrieval request submitted by users and converted to specification format which the system can identify. Using distance-based semantic similarity algorithm which adds edge type for quantizing semantic distance between concepts, this algorithm improve the accuracy of quantitative the semantic similarity between concepts, and building a semantic retrieval for communication ontology system.
