A Study on Semantic Query System and Key Technologies of Distributed E-catalogues

With the emergence of the E-catalogue, there has been an increasingly wide application of commodities query in distributed environment in the field of E-commerce. Existing methods such as query based on key words and goods' attributes can not meet the needs of E-catalogues query in distributed network environment. This paper designs a semantic query system structure of E-catalogues in distributed environment, achieves mappings among the different classifications of E-catalogue systems though ontology integration, and focuses on three key technologies: ontology generation, Chinese E-catalogue semantic dictionary and distributed database semantic query based on Sparql.
