A challenging problem in software engineering is to check if a program has an execution path satisfying a regular property. We propose a novel method of dynamic symbolic execution (DSE) to automatically find a path of a program satisfying a regular property. What makes our method distinct is when exploring the path space, DSE is guided by the synergy of static analysis and dynamic analysis to find...
Symbolic execution is an effective path oriented and constraint based program analysis technique. Recently, there is a significant development in the research and application of symbolic execution. However, symbolic execution still suffers from the scalability problem in practice, especially when applied to large-scale or very complex programs. In this paper, we propose a new fashion of symbolic execution,...
Popular Chinese text classification algorithms are mostly based on word frequency statistics features, ignoring the characteristics of Chinese text between the semantic relevance. To further improve the Chinese text classification results, the paper presents a new semantic-based kernel of SVM algorithm for Chinese text classification, through simple idea and smaller implementation costs. Experiments...
