OWL-based ontology indexing and retrieving algorithms for Semantic Search Engine

Various researchers have recognized that ontology based retrieval is one of the best in terms of precision and recall for semantic search engine. However, they did not specify explicitly any scheme/ algorithm for ontology based indexing and retrieval. This motivates us to conceive a proposal that includes (a) suggesting indexing algorithm to effectively maintain ontologies, (b) suggesting retrieving algorithm to process user query and produce results with better precision and recall. The proposed indexing algorithm has been tested manually considering a sample of ten OWL ontologies of mammal domain but presented only a result of two ontologies due to space constraint. Finally, the proposed retrieval algorithms have also been validated against three user queries.
