Aiming at the deficiencies of traditional blog hotness evaluation methods, the paper presents a blog hotness evaluation model based on text opinion analysis (named BHEM-TOA). The model not only considers the number of reviews, comments and publication time of the blog topic, but also focuses on the comment opinion. BHEM-TOA emphasizes subjective opinions of reviewers about the blog topic. It utilizes...
We present a scalable spatial decomposition coloring approach to implement molecular dynamics simulations with embedded atom method (EAM) on multi-core architectures. It effectively solves parallelization of reduction operations on irregular arrays in molecular dynamics simulations. In OpenMP program model, our methodology avoids that the same memory location is simultaneously modified by more than...
With growing scale of software, software architecture is becoming more complex and is hard to manage and control. Service Component Architecture (SCA) offers the supports for improving the complexity. However, few approaches address the complexity metric for SCA. In this paper, we propose a complexity metric based on SCA specification. The metric is composed of three parts that are employed respectively...
Web topic indicates the topic from Web pages on the Internet. Traditional methods to describe a Web topic come from text mining. However, Web page consists of not only text but also multimedia contents, such as image, audio, video and so on. The multimedia contents of Web topic can't be denoted by text-based representation methods. This paper proposes a new approach, named multi-layer representation...
Verification for interaction protocol of Web services is crucial to both implementation and composition of Web services. The verification process can prove important and desirable properties of the control flow and data flow of Web services. Model checking is a promising technique for verification and validation of software systems. In this paper, we present a model checking framework to specifying...
Timing constraints verification (such as time consistency) for service flow has become indispensable since many services for e-business are distributed in different places with temporal context. Unfortunately, current researches mainly focus on the modeling, analyzing and verifying of service processes, while ignoring temporal factors. To address the challenges of temporal properties verification...
