The context in intelligent domotic home (IDH) is very complicated. In this paper, in order to achieve the context-aware ability based on the DOG (domotic OSGi gateway) which is desiged for IDH, not only the information about the domotic devices and the building components, but also the characteristics and behaviors of users are concerned as the context. According to the context, a new context ontology...
The paper has proposed an ontology-based case reasoning method, the method can make task oriented capability requirement analysis come true automatically. On one hand the method uses ontology to represent information of task and capability requirement in case, the method can make knowledge to be formalized sharing, meanwhile it uses OWL to perform associated reasoning between the task and capability...
Traditional statistics based text classification methods almost construct their characteristic vectors with some key terms, and they consider terms are independent of each other and there are no semantic relations among them. However, in the real world, words used to have semantic relationships, such as synonym, hyponymy and so on. Therefore, classification methods based on statistics do not conform...
With the theories and methods of project management, and knowledge systems engineering, the development process of knowledge management system (KMS) was analyzed to guide the implementation of knowledge management project. And it was a foundation to establish the quality control system of knowledge management system based on benchmark Based on the quality characteristics with software engineering...
Ontology matching is the key process of semantic interaction and knowledge sharing. It is the basement of the other semantic web application, such as, semantic web-based service, ontology alignment. The purpose of ontology matching is to reuse the ontologies and integrate them in different fields, so as to implement the bigger pool of information and knowledge for the new communication and application...
Currently, OWL-S and WSMO are two popular frameworks that are used to describe semantic Web service. However, due to mainly focus on the description of the functional part, it is difficult for them to select the best services with consideration of quality of service (QoS). To solve this problem, the WSMO specification is extended and an ontology-based meta-model of QoS called WSMO-QoS is presented...
To improve the mobile searching efficiency in 3G mobile telephones, a personalized searching technology based on subject-word customizing model is presented, which is focused on the semantic association among subject words. First, a knowledge bases describing model about subject-word according to ontology is proposed. Second, the article researches to use the meanings of subject words to match combined...
In this paper, the ontology-based geometry knowledge acquisition is presented and the classes, attributes, relations, axioms are acquired by using this method in the field of geometry. Simultaneously, the ontology-based geometry knowledge representation is presented, and the geometry knowledge is turned into this domain ontology by using RDF/OWL form as a base. On it constructs shareable, reusable,...
In order to increase the correctness and the recall of vertical Web search system, a novel Web crawler ORC is proposed in this paper. By introducing ontologies, the semantic concepts are defined. The relations between ontologies are exploited to evaluate the importance of Web documents' context. These ontologies are organized by a network structure that is updated periodically. Thanking to the ontology...
The W3C recommendation named RIF provides a standard format to facilitate the exchange of rules. After being translated to RIF, the rule language needs a rule engine to perform inference. On the condition that there is no specific rule engine to RIF, this paper proposes the idea of using common rule engine to reason RIF. A system named RIF2Jess is designed. This system translates RIF rule to Jess...
In this paper barcode recognition and voice broadcast based on distributed system semantic search is discussed, the difference between text search and semantic search is introduced. The speech synthesis based on data matrix was constructed. The ontology of voice broadcast based on semantic search was established. Our study has shown that study of voice interaction and barcode recognition in 3G network...
XML/EDI has a deep influence on B2B development, benefits all XML/EDI participants despite they are big or small companies; but there are some problems in application of XML/EDI. This paper discusses these problems and put forward a solution by constructing a virtual Web service to solve the problems of integration application between XML/EDI and Web applications. Virtual Web service gives a unified...
Based on the Hall three dimensions structure and knowledge management maturity model, a methodological framework on knowledge systems engineering was analyzed to guide the implementation of knowledge management project. With the theories and methods of project management, organizational management, knowledge management and systems engineering, the development process of knowledge management system...
This paper presents an ontology-based method to implement aero-engine compressor blade procedure quality analyzing. Knowledge descriptive method based on ontology is proposed to describe some relevant information involving in the compressor blade manufacturing process. The information includes product feature, part quality requirement, process planning, gage &tools, equipment working condition...
In natural language, it is very common that one word has several different meanings. The well solution of word sense disambiguation (WSD) problem is the basis of natural language processing. In this paper, based on the certainty of word sense in certain language context, a new method is put forward based on ontology to solve the problem of WSD. And also, a prototype is developed to solve the WSD of...
Ontology is a normative explanation on formal common concept and it is a grade conceptual description about the given object and its relationship. In view of the difficulty of the problem representation, simulating the thinking circumstance of the expert solving problem, a new CBR for solving complex problems based on ontology is proposed in this paper. Besides that, this paper analyses the key technologies...
This paper introduces the SOA (service-oriented architecture) method into the adaptive learning system in semantic web. The author argues the key topics in SOA, and then a SOA solution based semantic learning web is proposed. According to this initial solution for the design and development of such learning services, the existing heterogeneous learning systems and all kinds of educational resources...
Service-oriented computing (SOC) is the computing paradigm that utilizes services as fundamental elements for developing applications. The modeling and analysis of services-oriented software requirements is one of important study contents in SOC. Owing to frequent changes of individual or collective requirements, continuous evolution of system function and structure, the study object of services-oriented...
With the growing number of web services ,the importance of matching and discovery web services is increasing. Using domain ontology to describe the semantic of web services and matching the web services on the semantic level is a hot research pot. In this paper, the problem of matching web services is transformed to the computation of semantic similarity between concepts in domain ontology. We propose...
In the active service model, the existing component retrieval method is not sufficient to meet the service requirements of intellectualization, individualization and comprehensiveness. Therefore, this paper designs a component retrieval framework for active service, proposes a component description model and component retrieval strategy based on ontology technology and assists the users to complement...
