| dc.description.abstract | Keyword based information retrieval system is affected by factors like synonym, polysemy and the manner in which queries are delivered to the retrieval system. Ontology is one of the semantic technologies employed in the information retrieval system to overcome the problems related to variations in document and query representation. It is achieved through explicitly specifying concepts and their relationships so that different components have common understanding of concepts to work in liaison. In the Implementation of Afaan Oromo Ontology on Sport Domain, ontology is developed on sport domain. The ontology was developed using Protégé 4.3 in which 317 classes, 1748 individuals, 7747 axioms, 5455 logical axioms, 191 object properties, and 17 data properties were identified. OWL Ontology that uses Pellet reasoner for information classification and consistency checking is developed. Implementation of the developed system is evaluated on the information retrieval of Afaan Oromo text using precision of the retrieved documents. Comparison is made between ontology aided Afaan Oromo text retrieval system and retrieval executed directly by using the queries as they are. Afaan Oromo information retrieval using the developed ontology on query operation stage has recorded a precision of 81.61% against 32.16% precision when the Ontology is not used. Queries used to test performance of the system have descriptive nature in which the description of the information needed is delivered to the system than the direct keywords by which the required items can be retrieved. | en_US |
