As an important branch in the field of frequent pattern mining, approximate frequent pattern (AFP) mining attracts much attention recently. Various algorithms have been proposed to discover long true AFPs in presence of random noise. This paper considers the key issues of AFP mining in noisy databases, and categorizes the previous approaches according to the ways they cope with missing items in the transactions. And then a study of different data models on AFP is presented, in which the merits and defects are analyzed. Finally, we draw a conclusion and propose some solutions to deal with the problems in the field of AFP mining.

API protocols are important for modern software development. They can be used in program testing, documentation, understanding and validation. Mining API protocols based on probabilistic models is proved to be an effective method to achieve protocols automatically. In this paper, we discuss the unbalanced probability problem caused by loops and recursive functions in application programs and a method based on the suffix tree is proposed to address it. In order to investigate the feasibility and effectiveness of our approach, we implemented it in our previous prototype tool ISpecMiner and performed a comparison test based on several real-world applications. Experimental results show that our approach can achieve protocols with more balanced probabilities than existing approaches, which provides a strong assurance for achieving valid and precise API protocols.

At present, the resources integration and sharing efficiency between the government systems is not high in China. The phenomenon of repeated system development is common, which results in a tremendous waste of resources and cannot be adapt well to the information exchange, sharing and unified management of the current government systems. Aiming at the unified management of government information resources and according to the actual shared requirement of government information resources, this paper studied the overall structure of the e-government sharing platform for the achievements of business collaboration between inter departments and the solution of "information isolated island" phenomenon between different heterogeneous systems of various government departments. The overall structure designed by this paper will provide technical support for realizing the cross-platform, cross-application, cross-system, cross-regional resource data interoperability and resource information sharing in government systems.

Reconstruction Method of Network Forensics Scenario has grown into a mature and rich technology that provides advanced skills to get the chain of evidence. Using statistical methods to analyze intrusion logs in order to present evidentiary values in court are often refuted as baseless and inadmissible evidences which is not considering the input spent. These spendings is to generate the reports no matter they are well-grounded evidences or not. Thus, this paper presents the Scenario Reconstruction Method combines the Viterbi algorithm, the most likely sequence of Meta evidence which replaces the Meta evidence was acquired. With suspected evidence, thus obtaining the chain of evidence. However, the Viterbi algorithm parameters is derived from the Baum-Welch (B-W) algorithm, and the B-W algorithm is easy to fall into local optima solution. While an Adaptive Genetic Algorithm (AGA) is used to estimate parameters of the Hidden Markov model (HMM), where Chromosome coding method and genetic operation mode are designed. The experimental results show that, this method can accurately reproduce the crime scene of network intrusion, compared with the network forensic evidence fusion method which is based on the HMM. The method has been applied to forensics system, and has obtained good result.
