Semantic Ontology Construction and its Application of Semantic Retrieval in Cloud Environment

With the wide application of cloud technology, semantic retrieval in cloud environment becomes a important research content, but semantic ontology must be constructed.This paper firstly put forward data deployment strategy based on the similarity, object data will be deployed to different virtual machine according to the structure similarity and semantic similarity of the concept.and then semantic ontology will be constructed respectively and the corresponding semantic retrieval algorithm is proposed.
