WESONet: Applying semantic web technologies and collaborative tagging to multimedia web information systems

The publication of different media types, like images, audio and video in the World Wide Web is getting more importance each day. However, searching and locating content in multimedia sites is challenging. In this paper, we propose a platform for the development of multimedia web information systems. Our approach is based on the combination between semantic web technologies and collaborative tagging. Producers can add meta-data to multimedia content associating it with different domain-specific ontologies. At the same time, users can tag the content in a collaborative way. The proposed system uses a search engine that combines both kinds of meta-data to locate the desired content. It will also provide browsing capabilities through the ontology concepts and the developed tags.     

基于构件复用的社会化软件工程模式

论述社会化软件工程概念,提出了基于构件复用的社会化软件工程模式。在该模式下,软件生产分为软件构件生产和应用软件生产,两类生产都通过全球网,按照市场机制,分工合作,形成全新的软件生产模式。为了适应这种生产模式,一种新型的ＣＡＳＥ被提出,这种ＣＡＳＥ分为构件生产ＣＡＳＥ和应用软件生产ＣＡＳＥ。文中介绍了这种ＣＡＳＥ的结构,并且分析了与传统ＣＤＳＥ的区别。     

A survey on search-based software design

This survey investigates search-based approaches to software design. The basics of the most popular meta-heuristic algorithms are presented as background to the search-based viewpoint. Software design is considered from a wide viewpoint, including topics that can also be categorized as software maintenance or re-engineering. Search-based approaches have been used in research from the high architecture design level to software clustering and finally software refactoring. Enhancing and predicting software quality with search-based methods is also taken into account as a part of the design process. The background for the underlying software engineering problems is discussed, after which search-based approaches are presented. Summarizing remarks and tables collecting the fundamental issues of approaches for each type of problem are given. The choices regarding critical decisions, such as representation and fitness function, when used in meta-heuristic search algorithms, are emphasized and discussed in detail. Ideas for future research directions are also given.

Theories, tools and research methods in program comprehension: past, present and future

Program comprehension research can be characterized by both the theories that provide rich explanations about how programmers understand software, as well as the tools that are used to assist in comprehension tasks. In this paper, I review some of the key cognitive theories of program comprehension that have emerged over the past thirty years. Using these theories as a canvas, I then explore how tools that are commonly used today have evolved to support program comprehension. Specifically, I discuss how the theories and tools are related and reflect on the research methods that were used to construct the theories and evaluate the tools. The reviewed theories and tools are distinguished according to human characteristics, program characteristics, and the context for the various comprehension tasks. Finally, I predict how these characteristics will change in the future and speculate on how a number of important research directions could lead to improvements in program comprehension tool development and research methods. Dr. Margaret-Anne Storey is an associate professor of computer science at the University of Victoria, a Visiting Scientist at the IBM Centre for Advanced Studies in Toronto and a Canada Research Chair in Human Computer Interaction for Software Engineering. Her research passion is to understand how technology can help people explore, understand and share complex information and knowledge. She applies and evaluates techniques from knowledge engineering and visual interface design to applications such as reverse engineering of legacy software, medical ontology development, digital image management and learning in web-based environments. She is also an educator and enjoys the challenges of teaching programming to novice programmers.     

Identification of defect-prone classes in telecommunication software systems using design metrics

The goal of this paper is to investigate the relation between object-oriented design choices and defects in software systems, with focus on a real-time telecommunication domain. The design choices are measured using the widely accepted metrics suite proposed by Chidamber and Kemerer for object oriented languages [S.R. Chidamber, C.F. Kemerer, A metrics suite for object oriented design, IEEE Transactions on Software Engineering 20 (6) (1994) 476-493].This paper reports the results of an extensive case study, which strongly reinforces earlier, mainly anecdotal, evidence that design aspects related to communication between classes can be used as indicators of the most defect-prone classes.Statistical models applicable for the non-normally distributed count data are used, such as Poisson regression, negative binomial regression, and zero-inflated negative binomial regression. The performances of the models are assessed using correlations, dispersion coefficients and Alberg diagrams.The zero-inflated negative binomial regression model based on response for a class shows the best overall ability to describe the variability of the number of defects in classes.

Engaging the net generation with evidence-based software engineering through a community-driven web database

Software engineering faculty face the challenge of educating future researchers and industry practitioners regarding the generation of empirical software engineering studies and their use in evidence-based software engineering. In order to engage the Net generation with this topic, we propose development and population of a community-driven Web database containing summaries of empirical software engineering studies. We also present our experience with integrating these activities into a graduate software engineering course. These efforts resulted in the creation of “SEEDS: Software Engineering Evidence Database System”. Graduate students initially populated SEEDS with 216 summaries of empirical software engineering studies. The summaries were randomly sampled and reviewed by industry professionals who found the student-written summaries to be at least as useful as professional-written summaries. In fact, 30% more of the respondents found the student-written summaries to be “very useful”. Motivations, student and instructor-developed prototypes, and assessments of the resulting artifacts will be discussed.

Semantic Web based innovative design knowledge modeling for collaborative design

This paper describes a study about how to use the Semantic Web technologies for innovative design knowledge modeling in a multi-agent distributed design environment. Semantic Web based knowledge modeling for innovative design is proposed as prelude to the meaningful agent communication and knowledge reuse for collaborative work among multidisciplinary organizations. A model for innovative design is proposed at first, based on which a knowledge schema is brought forward. For sharing the design knowledge among an internet-based or distributed work team, even globally, A RDF-based knowledge model is presented to realize its representation on Semantic Web. A Semantic Web based repository for innovative design and its API for topper Semantic Web applications have been also constructed. The proposed knowledge modeling extends traditional product modeling with capabilities of innovative design, knowledge sharing and distributed problem solving, and is employed as a content language within the messages in the proposed multi-agent system architecture. The proposed approach is viewed as a promising knowledge management method that facilitates the implementation of computer supported cooperative work in innovative design of Semantic Web applications.
