Basing on the relationship between the network location of college students in the class and the knowledge diffusion, we gave the students major in Information Management and Information System of a university some questionnaires for collecting data. We get the emotional relationship network, counseling relationship network and intelligence relationship network within the organization. This paper analyzed the key factors influencing knowledge diffusion and innovation through quantitative analysis about network density, centrality and the cohesive subgroup. And we lay the theoretical foundation for the formulation of related measures to improve knowledge diffusion in the undergraduate organization.

Semantic mappings between relational database and ontology are very useful in ontology-based relational data integration system. However, managing those semantic mappings is an arduous work in an open and dynamic environment. Aiming at facilitating the work of managing semantic mappings, a model named view graph is proposed in this paper. View graph retains the semantics discovered during the process of mapping construction, and these semantics may be reused in maintaining mappings. What's more, visualizing mappings based on view graph illustrates the semantics implicated in mappings, and this will help us understand those mappings.

Data Warehouse plays an important part in the process of decision-making for Enterprise, as a key component of the data warehouse architecture, the tool that support data extraction, transformation, loading(ETL, Extract Transformation Load) is a critical success factor for any data warehouse projects. Traditional methods of ETL development are difficulty to meet the Enterprise decision-making needs. To deal with these problems, we put forward a method of designing the ETL meta-model based on an integrated modeling framework of DW, which takes place of ETL modeling in the special data warehouse, and the design of ETL can be specified in the early stages of a DW project. It achieved the seamless Integration between ETL and data warehouse designed on conceptual level, reduced the development time and cost. Finally, we prove our approach usability and efficiency by practical application of this model.

In order to extract traffic state information and provide decision support for traffic management, Granular computing theory was applied in traffic information processing. Traffic information granule and its granularity were defined, and then a methodology that provides a framework of traffic management and decision-making was presented based on GrC. A method was proposed for traffic state information granule construction based on vague sets, and then travel state identification model was proposed based on traffic state information granule similarity. The methods of traffic state information granule construction and their granularity were discussed based on a demonstration network in detail. The results show that the existing traffic information processing methods could be integrated based on GrC, and the proposed methodology can satisfy the demand of traffic management decision-making.

Under the enormous uncertainty environmental condition, rational and procedures of decision making has been difficult to work effectively. Making decisions by intuition is increasingly viewed as a viable approach at a time of rapid and unprecedented change in the business environment. In this article, we empirical test the proposition that Dane, Pratt(2007) [1] proposed. And, it also expands the research about role of intuition in decision making. Furthermore, we study on the relation between the domain knowledge factors and the effectiveness of intuition in decision making. We also have suggested domain knowledge factors that may lead managers to make good decisions quickly.

On the basis of SVAR model, we analyzed the interaction between the investment behavior of securities investment funds and the volatility rate of return in an emerging stock market by the data in China for the period 2006:11-2008:12. The results showed that, the stock market and the securities investment funds exhibited a significant correlation; And the stock market was largely impulsed by the investment behavior shocks, While the response of securities investment funds to the stock market shocks was not significant and lasted shorter time. We proposed that, securities investment funds did not play a role of stabilizing the market fluctuations in an emerging market, on the contrary, it caused the market fluctuating even more violently.

Most previous sequential mining algorithms have the following two main drawbacks: On one hand, all sequential patterns are treated uniformly while sequential patterns have different importance. On the other hand, most of the sequence mining algorithms still generate an exponentially large number of sequential patterns when a minimum support is lowered. In this paper, a weighted closed sequential pattern mining algorithm called WCloSpan is proposed. WCloSpan generates fewer but important weighted sequential patterns in large databases. Our main approach is to push the weight constraints into the sequential pattern growth approach while maintaining the downward closure property. Furthermore, the problem of closed sequential pattern is transformed into closed itemset. Thus, pruning strategies of closed itemset can also be used to enhance the mining efficiency. Experimental results show that the algorithm is efficient and effective.
