Abstract: This paper presents a new reduction algorithm of granularity - reduction algorithm of granularity of Property resolution. This result has certain theoretical significance and application value in establish the granularity in the information system and attribute reduction. And it gives its application of whether suffering diabetes.

Abstract: This article provides a brief introduction to Natural Language Processing and basic knowledge of Chinese Word Segmentation at first. Chinese Word Segmentation is a process of turning a series of Chinese characters into a series of Chinese words with some rules. As the fundamental component of Chinese information processing, it is wildly used in correlative areas. Accordingly, research on Chinese Word Segmentation has important theoretic and realistic meaning. In this paper, we mainly introduces the challenge in Chinese Word Segmentation, and presented the categories of Chinese Word Segmentation method.

Abstract: This article provides a brief introduction to Natural Language Processing and basic knowledge of Machine Learning and Support Vector Machine at first, and then, gives a more detailed introduction about how to use SVM models in several major directions about NLP, and at the end, a brief summary about the application of SVM in Natural Language Processing is given.

Abstract: Drawing charts are odd work by adding a data source manually and setting other parameters such as border, legend etc in Excel. The key technologies and implementation methods of chart-automatic-drawing are described using embedded VBA Programming codes.

Abstract: To improve the global convergence speed of classical social cognitive optimization (SCO) algorithm, a novel hybrid social cognitive optimization algorithm based on quantum behavior (QSCO) is proposed. In the proposed algorithm, learning agents learn in a quantum multi-dimensional space and establish a quantum delta potential well model. A quantum search process is incorporated into local searching operation so as to enhance the local searching efficiency in the neighboring areas of the feasible solutions. Simulation results on a set of benchmark problems show that the proposed algorithm has high optimization efficiency and good global performance.

Abstract: A scheme to address router nodes is given for wireless Mesh Networks (WMN) with multiple input multiple output (MIMO) character. Both the wireless transceiver number of a node and geographical topology mesh contribute to wireless overlay model by placing link into different channel planes edge in case of interference. The triangular mesh is an important overlay topology for wireless networks. The router node addressing scheme keeps its instinct symmetric property. Several general cases over the addressing scheme are also discussed for the shortest routing path and the node coordination itself. The interference relation is abstracted into set models. Furthermore, the length of the shortest path is also given by a formula with the source node and destination node addresses. A general conclusion on relation of node address and hop count is also given.

Abstract: Rough relational database model provided a processing method for uncertainty data, So based on the Hash technology and the data characteristic of rough relational database, it was researched the multiple value data item in the rough relational database represented by binary string in virtue of equivalence classes, calculated its decimal value, and constructed Hash Function. Then according to the decimal number distributed Hash address where stored the data of the rough relational databases. Finally, an algorithm for constructed method of Hash function for the rough relational databases was described and illustrated by an example,and proved the method is validity and practicability.

Abstract: XBRL is the latest technology used in processing accounting information. Elements in XBRL are facts which may be reported about a business activity. Element names are the character strings which uniquely identify each element. This paper examines the existing rules on element naming. With extensive analysis of current practices for XBRL element naming in the foreign and Chinese taxonomies, several alternative approaches are set out. The considerations are proposed to improve the standardization of taxonomy creation.

Abstract: Aiming at the task scheduling problem of the cloud computing, this paper proposes a dynamic task scheduling strategies based on MVFSA (Modified Very Fast Simulated Annealing) algorithm. The simulation results show that this strategy can improve the computation efficiency of the cloud computing, and maximize the quality of service for users.

Abstract: In the past decade, Internet of Things (IoT) has experienced a rapid development, but the accompanied security problems were discussed rarely. To some extent, it restricted the development of IoT. This paper summarized the security characters of IoT, discussed relevant security issues of different layers, especially in the perception layer. Finally from the aspect of some emerging technologies, this paper prospected the future develop trends of IoT.
