Web services hold a great promise of implementing the B2B e-commerce by dynamically integrating business processes over the Internet. It is necessary to automatically and accurately select appropriate Web services satisfying client requirements before and after integrating business processes. However, current Web services standards do not well support it. We propose a formal method to select appropriate...
In order to solve problems of semantics recognition and information extraction in the process of service composition, we proposed a Petri Net model of semantics service composition based on Ontology. Firstly, which build a described approach of semantics service composition ontology-oriented, and exploits property of WSMO to describe; Secondly,build Petri Net model of semantics service composition,...
Ontology is an explicit formal sharing conceptualization of one domain. Ontology maintenance is one of most important work during ontologypsilas development lifecycle. Cycle of concepts is one of the most common inconsistency errors in ontology. In this paper, we propose a method of eliminating direct super-class to detect cycle of concepts (EDS2DCC). This method firstly constructs oriented graphs...
Services are offered by service providers, which procure service implementations and maintenance, and supply service descriptions. For Web services to become practical, an infrastructure needs to be supported that allows users and applications to discover, deploy, compose and synthesize services automatically. The essence of the Web service is the process on marching between the userspsila request...
In the paper, we introduce a music knowledge question answering system based on ontology knowledge base. Users can propose a question about music knowledge in natural language, the system automatically extract relative knowledge to form answer based on FAQ (frequently asked questions) and ontology knowledge base, and return the answer to users in natural language. The important modules in the question...
Manufacturing Execution System (MES) links plan management and workshop control in an enterprise, which is an integrative management and control system of workshop production oriented to manufacturing process. To overcome the difficulties of traditional components retrieval method, retrieval of MES components based on ontology is put forward to prompt retrieval efficiency and recall ratio. Retrieval...
Ontology mapping is a core task to achieve interoperability among the distributed and heterogeneous ontologies. The quality of ontology mapping is still not good due to the inconsideration of semantic information of the ontology. This paper proposes an ontology mapping method based on tree segmentation. It first divides the ontology into a set of sub-trees with different granularities according to...
