Abstract

This paper presents a framework of a search engine based on domain ontology’s. Semantic search requires the search engine to properly interpret the meaning of a user’s query and then bring about terms with respect to a specific domain. The traditional approach involves search based on the criteria given by the user thus lacking the semantic understanding of the user’s Query. The paper here proposes the use of a novel-ontology-based semantic search engine which takes into consideration the domain or semantic meaning of the user’s query. The solution adopted here takes into consideration the RDF (Resource Description Format) based approach which helps to convert the unstructured data into structured format. Semantic web technology enables to capture relationships and associations as metadata. RDF is used to represent information modeled as a graph – a set of individual objects along with a set of connections among those objects. RDF represents the graph as triples as in subject, property and object .The associations are represented as property between the objects which are the subject and object connected by the property.[2] Overall it can also be stated that RDF is the pillar of Semantic Web. Here RDF-XML is used to serialize the information represented using graphs and RDF is being read in by the JENA software package. The Eclipse IDE is used as a text editor to develop this solution which involves Protégé to construct an RDF File. In this framework, a search request which can be either a keyword list as in traditional search methods or a query in complex form containing various restrictions to the search. This is first processed by the SPARQL engine and is queried by the SPARQL query language which then finds qualified RDF triples in domain ontology.[3] Web documents relevant to the requested concepts and individuals specified in these triples are then retrieved by a document retriever. Finally the retrieved documents are ranked according to their relevance to the user’s query.
