It is the basic way to enhance service ability to predict customer behavior in the process of E-commerce activities. Through applying temporal description logic (TL-ALCF) in describing the rules of time-dependent customer behavior change, this article puts forward a method in acquiring algorithms through improving the temporal correlated rules of the FP-tree(frequent pattern tree), and further constructs...
The neural networks have been widely applied to optimum calculation and solution of complicated problems. In particular, the evolutional learning neural network has better characteristic and higher precision than other neural networks. But the slow computational rate of evolutional learning and the local-optimum of the evolutional learning neural network seriously influence its application. In this...
With the development of computer technology and network invasively and continuously, computer has already become a part of our life. Computer could supply new teaching mode combined education with game. Now college should be education between oriented-student and oriented-society which cannot stick into textbook, but can blend theory and practice. Therefore, animate and visualized education mode is...
A new method to compute Chinese text concept is proposed in this paper. In this method, we construct sentence vectors from the text by extracting and quantifying some syntax and semantic features such as concept elements, dependent relations and correlative relations. Then, we combine these sentence vectors to the text vector to represent the text concept. Experimental results show that, in the application...
This quantitative study investigated the impact of digital divide factors on perceived motivation to utilize technology to learn English. Four latent digital divide related constructs were determined by factor analysis. They are a) perceived computer and Internet skills, b) school-related Internet use, c) computer and Internet resources outside the home, and d) gaming/leisure use of the Internet....
A P2P volunteer computing system named PPVC is proposed. Its advantages are the flexible topology and the scalability. Volunteers are organized as a P2P network and a decentralized job scheduling method is utilized. It can accomplish an application efficiently under the dynamic changes of the P2P network condition. PPVC is built using an AOSE method and developed on the MAGE environment. The whole...
Contrasting with the data processing at the low frequency, the integrality of sampling signal must be thought at the high frequency. In this paper, some important amplitude extracted algorithms for the digital spectrometer, including peak-to-peak value, curve fitting and statistic algorithm, were researched on the LabVIEW platform. The results show that the resolution of the statistic algorithm is...
In this paper, a P2P volunteer computing system, PPVC, is presented. Volunteers are organized as a P2P network, i.e. there is no central server and every volunteer has the same function. It uses a decentralized job scheduling method so that each volunteer only need to communicate with its direct neighbors but an application is able to be distributed to all the volunteers. Using this job scheduling...
