In the converged network environment, owing to diversification of user demand and diversification of services, the existing semantic service discovery algorithms almost have the problem of too long service response time. With respect to this current situation, this paper proposes a novel services semantic web service discovery method based on user preference cluster. Firstly, this paper optimizes...
For the lack of effective methods of service aggregation in convergent network and diversification of user needs, we proposed a user preferences-driven dynamic service aggregation model (UPDDSAM) and the corresponding aggregation algorithm. This model implements run-time aggregation of service processes and service resources by adopting dynamic rules and late-binding technology. At the same time we...
To increase the agility of the chain store operation with the information technology, the communication system is proposed with the mobile networks to link the headquarters with the chain stores distributed widely. In the store, the mobile is attached to POS with USB, and the data exchanging service is developed on the mobile to report the sale data and to download the updated data. At the headquarters,...
Instead of the original wired IP networks, the mobile networks are used as the return channel in IP-QAM VOD system to take the advantage of their wireless data communication function and full coverage in cities. The mobiles are used as a virtual remoter of STB for demanding video programs and controlling their playing. The function of complex query for programs can be realized based on the mobile's...
At present, there are an abundance of learning resources and different E-Learning systems on the Internet, and the sharing and reuse of these resources is a very worthwhile study. Learning object technology and service-oriented software development methodology are two important aspects of E-Learning research, which emphasize the modularization of data information and system functions respectively,...
OWL-S is an ontology language of semantic Web service which is recommended by W3C. Using OWL-S to describe semantic web service and implement automatic composition is a hot topic in today's web service research domain. Planning is a task of finding action sequence to achieve some targets. Web service automatic composition can be solved through translated as planning problem. This paper firstly introduces...
The current telecommunications network can only provide syntax-layer services and not provide semantic-layer services. We present an ontology-based modeling method for telecommunication services that is not only an effective solution to the current telecommunications network, but also lays the foundation for convergent services with semantic information. Firstly, we propose the mathematical model...
