So far, most Chinese natural language processing neglects the punctuations or oversimplifies their functions. To improve the efficiency of Chinese similarity computing, this paper gives a Chinese similarity computing system model in accordance with the problems of Chinese sentence similarity computation aspect. This model is a combination of punctuations and traditional similarity computing. Comparing with Cosine-based Similarity calculation, the sentence similarity calculation based on word shape and word order, and Sentence similarity calculation based on semantic, this model makes up their insufficiency to a certain extent. The experiment shows that this model has a higher rate of accuracy in Chinese similarity computing.

In this paper, we propose a novel, hybrid approach to optimize the query expansion source. The main idea is that, on one hand, we analysis the documents selected by user and use the knowledge of Formal Concept Analysis to construct a user concept lattice; on the other hand, we find some documents which are different from the documents mentioned above and build another concept lattice. Then we calculate the concept similarity through a novel method to identify the concepts which have higher similarity with the user concept lattice. Finally, we extract the extension of these concepts and add them to the user document set; consequently we can optimize the query expansion source. The experiment results show that our method is quite reasonable.

The objective of this paper is to implement the Active Network based Active Queue Management Technique for providing Quality of Service (QoS) using Network Processor (NP) based router to enhance multimedia applications. The performance is evaluated using Intel IXP2400 NP Simulator. The results demonstrate that, Active Network based Active Queue Management has better performance than RED algorithm and is well suited to achieve high speed packet classification to support multimedia applications with minimum delay and Queue loss. Using simulation, we show that the proposed system can provide assurance for prioritized flows with improved network utilization where bandwidth is shared among the flows according to the levels of priority. We first analyze the feasibility and optimality of the load distribution schemes and then present separate solutions for non-delaysensitive streams and delay-sensitive streams. Rigorous simulations and experiments have been carried out to evaluate the performance.

SITE model was developed to study the response of tropical ecosystems according to environmental conditions for estimating of energy fluxes. This study analyzed the net ecosystem of CO2 exchange (NEE) by ecosystem modeling and field measurements in a semi deciduous forest located at 50 km of Sinop municipal district, Mato Grosso, Brazil. Continuous measurements of canopy CO2 storage and fluxes of CO2 were made in a tower of 42 m height using an eddy covariance technique. For ecosystem modeling was used SITE to estimate the NEE. SITE required a setting of parametrization. The better performance of the SITE model to estimate NEE was obtained during the wet season.

The traditional evaluating methods can not deal with the evaluation problem of innovation sources in service firms with fuzzy information, authors have constructed fuzzy support vector machine based on support vector machine and fuzzy chance constrained programming, and applied this new method to evaluating innovation sources in service firms. In basis of related literature reviewing, authors have summarized 7 indicators of innovation sources in service firms which are internal R&D, staff quality, customers, suppliers and so on. By selecting the data of 80 service firms of Zhejiang Province in China as samples and 60 firms being as training samples, we obtain the model of evaluating innovation sources of service firms. Simultaneously the other 20 firms being as testing samples, the results show higher accuracy rate (90%) and lower error rate(average error is 0.038). Therefore fuzzy support vector machine method for innovation sources in service firms provides a new way in the process of selecting innovation sources.
