Abstract: Since the current web-based parts libraries lacked of autonomy and self-service,an open parts library system based on domain ontology organization and HTML5 technology implementation was built,which could provide data viewing functions such as self-service applications,semantic retrieval and parameter dynamic selection.The domain ontology was built to organize the resource data of parts library,and its completeness was checked by the inference engine.The data properties and individuals in the domain ontology were maintained based on self-service parts information published by suppliers.The semantic similarity algorithm was proposed to match the classes of domain ontology with the user's searching intent and further expand the outcomes of information retrieval.Based on the HTML5 technology,the system could be deployed on multi-operation system and mobile device without using plug-in.By using Asynchronous JavaScript and XML(AJAX)technology,the upload and interactive parts selection from a dynamic XML was realized.The prototype of the Web-based parts library was developed,and the algorithm of semantic similarity was evaluated which could satisfy the semantic retrieval demands.
