Semantic Searching Of Biological Documents Using Gene Ontology

a framework for a semantic biological retrieval system that effectively searches and retrieves meaningful results using Gene Ontology. The system takes two related biological terms as an input and retrieves relevant documents which contain these inputs. Since the user searches for the documents that contain two related biological terms, the system helps the user to know the hierarchical relationship between these two terms using Gene Ontology. The system utilizes the Gene Ontology to infer semantically related terms to the inputs. The inferred words may include synonyms, parents and grandparents of the input terms entered in the search query. The system uses these related inferred terms in expanding the user query to produce meaningful results since it retrieves the documents that contain the input terms and these inferred related terms. The system uses a ranking methodology to help in ordering the retrieved documents based on the rank values. The proposed technique improves the precision of the retrieved documents as well as the recall which saves researcher time and focus.
