To improve sharing and reusability of designing knowledge in domestic enterprises, a proposal of sharing of knowledge based on functional ontology was proposed. By using bases of knowledge of functional ontology, the mapping of structure-to-function has been realized. On basis of comprehensively understanding original functional model, through changing way of function achievement to obtain new functional...
Traditional agricultural knowledge service is based on keyword rather than content, the recall rate and precision rate cannot to be improved. The knowledge representation based on semantic web can truly achieve the semantic-level knowledge service. This paper analyzes the status of agricultural knowledge service system and points out its shortcomings, elaborates semantic web technologies, studies...
In order to improve the recall ratio and precision ratio in knowledge retrieval of the product-design process, a semantic-oriented framework of product-design knowledge retrieval is presented. In this framework, the rule model is established to improve the ability of intelligent inference and solve the problem of polysemy. Then ontology model is established to improve the ability of semantic extension...
Knowledge visualization and retrieval are the key techniques to implement effective knowledge management. Traditional research on knowledge map emphasizes on building global view of knowledge base, but ignores its support to knowledge retrieval. In this paper, a searchable knowledge map model is proposed. Based on this model, we extent the search-ability of knowledge map and propose three practical...
Retrieving accurate information from the Web is a great challenge to users. The existing information retrieval systems are mostly term-based and thus need to be enhanced toward knowledge-based. User information needs need to be better captured in order to deliver personalized search results. In this paper, an ontology-based framework is proposed for capturing user information needs using a world knowledge...
The procedures used in previous injection mould repair schemes are viewed as valuable knowledge by many mould manufacturers. This knowledge is stored in computer on a case-by-case basis and can be used to form new repair schemes when needed by searching the database. With the enlargement of the database as more case is added, the efficient retrieval of the correct injection mould repair scheme has...
