Because Knowledge Management System (KMS) has large amounts of data and updates frequently, knowledge push technology is becoming more and more important. But the existing knowledge push technologies only considered individual characteristics. By analyzing the interested information of each KMS users' group and then extract the characteristics of every group, this paper, based on Ontology, introduces...
We propose a concept-based approach to video semantic analysis and coding for video retrieval. The proposed approach is aimed at bridging of the gap between the low-level video features and high level of semantics of video and providing a convenient and efficient way to create semantic descriptions and retrieve video. In the paper, we built an ontology model of the video semantic objects and described...
In this paper, we analyze the background of semantic web services firstly. Then we classify the services into two types: one is information acquiring services, the other is action services. According to the information acquiring services, which semantic description is simpler than general services, we propose an automatic service composition approach based on similarity computation between concept...
This paper catches the knowledge of the automotive fault diagnosis domain, provides a common understanding of the domain knowledge, determines the common vocabularies which are recongnized by the domain, and gives explicit definition of the relations between the vocabularies from different levels of formal module. Using Protégé builds the domain knowledge module, using RacerPro checks the module,...
As maintenance knowledge management is an important issue of maintenance of power plants, expresses and organizes the maintenance knowledge effectively is the key link in this field. Taking the ontology research results used in knowledge management field for reference, ontology technology is introduced to conception modeling for maintenance of power plants. S-B-F-P maintenance knowledge expressing...
In the logic system of structuralism, any component of the whole does not exist in an isolated form, it exists as a relationship with the others. The nature of the whole is not determined by the external factors, it is determined by the internal inter-dependent relationships of the whole. Therefore, starting from the concept of relationship enables us to hold the relation among every part that composes...
