    The authors propose a double auction-based method for grid resource management,and design a double auction-based grid scheduling model and describe the resource users, user agents, grid resource suppliers and local auction market of the model in view of the dynamic and heterogeneous nature of grid resources. Then the anthors put forward the double auction algorithm and resource scheduling strategy, which make the two transaction sides both gain the maximal resource use in the condition of incomplete information by consulting the game mechanism. Then with the help of Bayesian study, an optimization bidding strategy for double auction is derivated, which supplies useful references to adjusting dynamic load balancing efficiently and improving usage rate of system resources.

    This paper presents a new algorithm for text character extraction and dimension reduction based on the Max Term Contribution. Its main idea is computing the contribution of each term in the high dimension document-base and extracting the maximum contribution terms to construct a low dimension document-base from the high dimension document-base using the search algorithm. Then a modified K-means clustering method based on the Simulated Annealing (SA) is presented to cluster the low dimension document datum which is obtained by MTC. Finally, some experiments show that the new method can improve the cluster precision.

     Aiming at the problem that the extration of topic information from Web page is not precise enough,this paper presents a new method of calculating the topic information of Web pages,which dividing the topic information of Web pages into three forms and using different quantization method for each. Based on the ideas above,the authors combine document object model with section thinking and present the IB-DOM model.Based on the idea of divide-and-conquer, first find the region which contains the topic information, then the irrelevant information is filtered out. The experimental results show that this approach can solve the contradiction between integrity and accuracy existing in the field of automatic extraction of topical information from Web pages betterly.

    After a perceptive analysis of probabilistic characteristics of syntax composition especially POS matching of Chinese textual information, a system framework for Chinese term recognition and extraction based on dual layer HMM is presented and implemented. The method proposed shows a good performance in the tests with textual information from different domain, and the terms recognized and extracted by the implemented system can be treated as candidate terms for false-eliminating and optimizing combining with parameters of mutual information, log likelihood and domain dependency.

    With the explosion of patent amount and stagger overlapping of new technique field, there is urgent need to deepen to content level in patent information analysis. Content mining is important approach and necessary means. Using the thought and technology of text-content mining, the content mining-based patent information analysis method system, and expounds the major steps and the various techniques and algorithms of the patent text information pretreatment, patent information content analysis and patent information knowledge treatment. Finally, the paper selects patent data in the area of Hybrid Electric Vehicle (HEV) to do empirical research.
