SimRank is a well known algorithm which conducts link analysis to measure similarity between each pair of nodes (nodepair). But it suffers from high computational cost, limiting its usage in large-scale datasets. Moreover, Links between nodes are changing over time. It may be desirable to quickly approximate the similarity score between certain nodepair without performing a large-scale computation on the entire graph. In our approach we propose a method to efficiently estimate the similarity score using only a small subgraph of the entire graph. We call this novel algorithm “Local-SimRank”. The experimental results conducted on real datasets and synthetic dataset show that our algorithm efficiently produces good approximations to the global SimRank scores. Meanwhile, we prove that the Local-SimRank score LS(a, b) is always less than original SimRank score S(a, b) mathematically.

This paper investigates the relationship between the use of predicate-based and statement-based program spectra for bug localization. Branch and path spectra are also considered. Although statement and predicate spectra can be based on the same raw data, the way the data is aggregated results in different information being lost. We propose a simple and cheap modification to the statement-based approach which retains strictly more information. This allows us to compare statement and predicate ''metrics'' (functions used to rank the statements, predicates or paths). We show that improved bug localization performance is possible using single-bug models and benchmarks.
With the popularization of digital products in modern society, the present popular software interface cannot meet individualized needs of customers. So the customization of the interface image has become a new trend. ...

The automated synthesis of software architecture design and associated work allocation plan is considered, given the requirements of the system and a specification of the available, possibly distributed development teams. The technique applies genetic algorithms, with mutations introducing changes both in the architectural solutions and in the work allocation schemes. The technique is implemented and evaluated using a non-trivial example system, the control system of an electronic home. The results suggest that genetic algorithms are a viable approach to solve this kind of multi-targeted optimization problem, assuming that the architectural quality and work allocation fitness can be given appropriate metrics.
