The past decades have witnessed a boom in online music industry as a result of rapid development of information technology. This emerging field, however, lacks appropriate pricing methods. In order to coordinate with the marketing strategies of online music and guarantee satisfactory returns for both sellers and buyers of online music, a pricing model based on Stackelberg Model and Particle Swarm...
Nowadays the core of social aggregation service is still about polymerization and recommendation of content. Yet, the mining of the user association behind the shared information is unsatisfactory. Based on static social tags, a new algorithm clustering users is proposed, which clusters users by their similarity. Firstly, relevant concepts are defined to be used in the algorithm. And then, by analyzing...
To improve the quality of 3G service recommending technology, a new 3G service recommendation algorithm was prompted based on clustering analysis and collaborative filtering. The algorithm can cluster the users with their behavior similarity to the commodities, and finds the nearest neighbor of an active user according to the clusters. Then the recommendation to the active user is produced by collaborative...
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...
With the further opening up of the financial marketing to join WTO, the banks in China will be confronted with tremendous pressure of competition. Meanwhile, with the development of information technology, E-banking has become a major inter-bank competition. In this competition process, the service quality to maintain long-term impact has become an important aspect of competitive advantage. According...
The current tools for process definition transformation only support fixed conversions from one definition language to another. A model transformation framework, which is able to achieve mutual conversions among a variety of process definition languages and is based on meta-model, is proposed from the common perspective of the mapping and transferring of models. The framework uses dynamic mapping...
In order to improve the reusability for the software testing automation procedures, at the same time support the program test for Linux, keyword-driven distributed test automation framework (LKDT) is proposed in this paper, which is based on the analyze of the recent automated testing frameworks and combined with the actual project practice for software testing automation. This paper presents the...
The United Model Language (UML) has been applied in various areas and disciplines. Among UML, the state diagram is an important descriptive means to model object state transition. But it is still lack of feasible and effective validation method which can be utilized to formalize and revise the UML state diagram. In this thesis, a new approach for this problem is proposed based on the polychromatic...
One of the most difficult jobs for requirements analysis engineers is to select the appropriate requirements analysis knowledge for the project at hand. Once the selected requirement analysis knowledge does not fit the current project situation, it is doomed that some requirements problems will be emergent and the final system canpsilat fit in with the enterprise needs at a great extent. Requirements...
The interface specification of components usually lacks behavioral semantics information. Behavioral semantics information specify component interaction constraints on the usage of interface methods, including the order in which these methods should be called and the constraints on the method arguments and returns of methods. Based on dynamic analysis technique, a method which abstracts interaction...
The behavioral semantics of component interfaces plays a significant role in the reuse, integration, validation and maintenance of components. However, the interface description specification of COTS component usually only contains syntax information, and lacks behavioral semantics information. This paper presents a method, called EKBehavior, for incrementally inferring a behavior model that represents...
Project situation is one critical key foundation of requirements engineering (RE) knowledge share and reuse. RE knowledge can be shared and reused under similar project situation. A new knowledge retrieve technology based on project situation similarity is proposed in this paper. Firstly, the tree models or hierarchy models of RE knowledge situation are presented. Secondly, three situation match schemes...
