Role of Ontology in NLP Grammar Construction for Semantic based Search Implementation in Product Data Management Systems Ahmed Zeeshan, Dandekar Thomas, Majeed Saman Department of Bioinformatics Biocenter, University of Wuerzburg, Am Hubland-97074, Wuerzburg, Germany Online published on 26 June, 2013. Abstract In this research paper we address the importance of Product Data Management (PDM) with respect to its contributions in industry. We also present PDM Systems in brief and highlight some of major challenges to the PDM communities in advance PDM system development. Targeting some of these challenges we present an approach and discuss how this approach can be helpful in solving the PDM challenges. Limiting the scope of this research to one challenge, we focus on the implementation of a semantic based search mechanism in PDM Systems. Going into the details, at first we describe the respective fields i.e. Semantic Web and Language Technology (LT), contributing in ontology construction and natural language grammar implementation, to take advantage in implementing a search engine capable of understanding the semantic output of natural language based search queries. Then we discuss how we can practically take advantage of LT by implementing its concepts in the form of software application with the use of semantic web technology i.e. Ontology. Later, in the end of this research paper, we briefly present the prototype application developed with the use of concepts of LT and Semantic web.
