Abstract— In the Digital Library fields, Ontology can be used to organize bibliographic descriptions, represent and expose the contents of the document, and share knowledge between users. In the proposed IR model, preprocessing, context matching, and calculating similarity values steps are included. The algorithm for the formatting of SPARQL query is developed in the context matching step of IR model. Ontology-based IR system for Digital Library is implemented in Service-Oriented Architecture (SOA) by using the XML Web Service technology and ASP.NET. The architecture of the proposed system consists of file storage for documents, one ontology dataset, and two programming components: Digital Library Web Service and Web Application. In this proposed system, Web Ontology Language (OWL) is used to design Ontology for Digital Library using Protégé v3.5 tool. Functions for publication and retrieving of documents are implemented as a web service by using the C# programming language. The user interface is designed and implemented as a web application in ASP.NET platform for consuming the functions of web service. The performance of this research paper, the precision, recall, and F-values are measured and compared. According to the comparison results, the Ontology-based IR system is more accurate in searching for ObjectProperty type. As a result, the proposed system serves user-friendly, high- performance and scalable semantic search for information from the digital library.

I.INTRODUCTION
Digital libraries (DLs) had become the digital counterpart of the traditional library system. There are various ways to improve the search technology for accessing documents from DL. In this research, Ontology-based IR system is proposed for Digital Library. Ontologies have the potential to play an important role in DL, because ontology defines a common vocabulary for researchers who need to share information in a domain. The proposed system intends to provide for students to retrieve the relevant information with their concept and to be able to search, read and download the textbooks, old questions (included tutorial, exam, multiple, assignments), journals, thesis papers, reference papers, novels efficiently in the short time.
