Abstract: The paper proposes a term weighting algorithm for research papers. It weighs a research papers annotated keywords according to a certain view. It uses a predefined multi-view fuzzy ontology and a stemmer NLP tool. The proposed algorithm is tested and results are compared with another ontology-based term weighting algorithm. The tests show that it enhances the resulted weights accuracy and decreases the execution time.

Abstract: In the paper, some properties related to the moment generating function of a fuzzy variable are discussed based on uncertainty theory. And we obtain the result that the convergence of moment generating functions to an moment generating function implies convergence of credibility distribution functions. Thats, the moment generating function characterizes a credibility distribution.

Abstract: In this paper, based on the methods presented Song, Yuan [Int. J. Comput. Math., 52 (1994) 195-20, we present relaxed matrix multisplitting chaotic generalized USAOR-style methods by introducing more relaxed parameters and analyze some applied convergence results of methods to be convenient for carrying out numerical experiments.

Abstract: For the exponential sequential model, we show that maximum likelihood estimator of regression parameter vector is asymptotically existence and strongly consistent under mild conditions

Abstract: The main objective of this paper is to establish a class of new nonlinear Volterra-Fredholm type difference inequality with iterative summation. By technique of change of variable, amplification method, difference and summation and inverse function, Upper bound estimations of unknown functions in the difference inequality are given. Finally, we study the estimation of the solution of a class of Volterra-Fredholm difference equation by our derived results..

Abstract: The main objective of this paper is to establish a class of new nonlinear Volterra-Fredholm type difference inequality, where the inequalities consist of multiple iterated sums. By technique of change of variable, difference and summation and inverse function, upper bound estimations of unknown functions are given. The derived results can be applied in the study of solutions of Volterra-Fredholm type difference equations.

Abstract: By combining the traditional iteration structure of Hash function with the dynamic S-boxes, a novel keyed Hash function is presented. The proposed approach can give a chaotic Hash value by means of the lookup table of functions and chaotic dynamic S-box. Compared with the existing chaotic Hash functions, this method improves computational performance of Hash system by using the chaotic S-box substitution. Theoretical and experimental results show that the proposed method has not only strong one way property, sensitivity to initial conditions and chaotic system’s parameters, but also high speed.

Abstract: SWOT analysis is a classical analysis tool of competitive intelligence. The affect depends on whether all internal and external factors were analyzed. The construction of index system of SWOT analysis requires a lot of human resource. To resolve this issue, a method for computer aided index system establishment of SWOT analysis is proposed. This method can be automated extract and classify the key words. And the index system of SWOT analysis is generated by words classified information contained in words categories. In addition, the method can generate suggestions of indexes weight according to the amount, frequency and timing of key words contained in their classes.

Abstract: Virtual laboratory for experimental teaching provided a new form, virtual reality modeling language (VRML language) for virtual laboratory construction provides economic effective means. Virtual experiment technology as a new teaching media, which appears to modern teaching will no doubt, especially remote teaching far-reaching impact .This paper discusses the realization method of the virtual laboratory based on VRML.
