Some web applications use the ontology to integrate multiple data sources because ontology-based data integration is the ideal solution to handle the semantic conflict. For accessing the data on ontology, ontology understanding query such as SPARQL is needed. However, end users enter the unstructured sentence (words, statements, etc.) as an input when they wanted to search the required information on the web. So, it is needed to extract the triplets (i.e. subjects, predicates and objects) from the input query to build the ontology browsing query SPARQL.
