Research On Semantic Synthesis Based On Domain Ontology

Abstract: With the development of cloud computing and Internet of things, there is also asubversive revolution of IT industy, that is the age of big data. Big data era reveals thecharacteristics of data on the network is massive and diversity, the content and the form is widelyvarious, the sharp increasing of data also makes the existing search technology is facing severechallenges. Most of the general natural language processing technology are based the syntaxlevel, lack of knowledge of the identification, processing and ability to understand, namely thelack of semantic unity of information resource description. Faced with a natural languagedescription of the massive data, it is hard for users to search the demand related information.This paper proposed a study of semantic synthesis model based on domain ontology, themodel uses the domain document as the data source, the mapping relation between the datasource and the domain ontology is refered to express semantic of the domain data. The paperpresents the semantic synthesis model based on damain ontology, which is composed of fieldresource document pre-processment, domain ontology, concept semantic similarity and semanticreasoning technology module.The model has been verified by experiments,whose results showthe the precision rate of experimental retrieval system, the process ability of the computer andthe user’s satisfaction are all improved through studing on semantic synthesis based on damainontology in this paper.
