There are many remarkable methods used in software semantics analysis. However, people find some of the methods generally have the common problem of high time complexity or inaccurate results. In order to solve these problems, we propose a program controlled flow algorithm which is based on a control dependency graph and an abstract syntax tree. This algorithm uses object program equivalent substitution...
Recently computer systems' call sequences are considered as a data source, this paper expounds how to use Hidden Markov Models (HMM) for software behavior recognition and trend prediction. Due to that HMM is sensitive to initial parameters, especially sensitive to B-parameter which makes model fall into a local optimum in training, this paper proposes using Genetic Algorithm (GA) approach to optimize...
There exists a variety of heterogeneous data that need to be integrated within a secure domain. How to integrate the security data from various data source safely is a challenge for database researchers. In this paper, we introduce a new model for security data integrity, Weight-value-Extended MLS (WEMLS), which is development based on MLS. Compared with MLS, WEMLS can not only guarantee the security...
There has been a lot of research into XML query optimization. In this paper, we focus on several techniques for XML semantic query optimization, which improve the query execution based on the information abstracted from the XML documents. The optimization methods will be discussed in two groups: optimization based on structure and optimization based on content. The query optimization mechanisms of...
