摘要	In this paper we have presented an information retrieval model for the semantic search that uses the ontology-based knowledge base to support semantic search over the document repository. Our approach can be seen as an evolution of the classic vector-space model, where keyword-based indices and RDF triples indices are complementary to each other, which makes it possible to retrieve more precisely documents that are related to the information searched closely. On the basis of that, we propose the consistent ranking algorithm that combines keyword ranking and semantic ranking. Our semantic retrieval algorithm outperforms keyword-based search from the two aspects of the precision and recall, and provides ground for the further research.
