Software Engineering Using RATionale

Many decisions have to be made when developing a software system and a successful outcome depends on how well thought out these decisions were. One way that the decisions made, and alternatives considered, can be captured is in the rationale for the system. The rationale goes beyond standard documentation by capturing the developers’ intent and all alternatives considered rather than only those selected. While the potential usefulness of this information is seldom questioned, it typically is not captured in practice. We feel that the key to motivating capture is to provide compelling uses and tool support integrated with the development environment. Here we describe the Software Engineering Using RATionale system which inferences over the rationale to evaluate decision alternatives and perform impact assessment when requirements, development criteria, and assumptions change.     

Experiences with Open Source Software Engineering Tools

For software engineering (SE) and computer science (CS) programs to deliver on their promises, they must go beyond teaching students about principles, processes, models, and strategies and offer them realistic, practical experience as well. Although industry has been pressing to increase the emphasis on practical aspects, many CS programs continue to give students relatively simple problems focused on selected computing and software concepts and theories. Open source software offers CS and SE educators an opportunity to give their students practical, hands-on software engineering experience

Developing Flexible Software Using Agent-Oriented Software Engineering

Software agents are associated with modern industrial software. In various application fields such as e-business, telecommunications, logistics, and industrial automation, software based on agents seems to make the challenges in modern applications easier to overcome. However, it's often unclear what a software agent is and why problems can be better solved with it. Is it concerning a technology, an architecture, or a programming concept? This article presents a general introduction to software agent concepts from the software engineer's perspective, explaining the theoretical basis and clarifying to which type of problem software agents might represent a reasonable approach.     

Multimedia Digital Rights Protection Using Watermarking Techniques

ABSTRACT

With the advancement of Internet technologies and its wide usage, it has become easy to illegally copy, distribute, and manipulate digital products. Digital watermarking is a proven method to protect authenticity by identifying the owner of the digital content. Significant work has been reported in the last five years on legal and technical measures for protecting digital rights. This paper explains the concepts of ownership rights and related intellectual property rights and their technical and legal protection measures. It also introduces digital water marking, its classification, features, and applications.

基于OWL的软件工程数据建模

网络本体语言(Web ontology language,OWL)是语义网技术的一个重要组成部分,适合于对复杂的数据进行语义描述和建模.在软件系统的开发过程中通常会产生大量结构复杂、语义丰富的数据,而建立一个灵活的语义模型是对各类软件工程数据进行统一管理的基础.从设计和实现海量软件工程数据管理平台的需求出发,提出了一种基于OWL的软件工程数据描述模型.该模型不仅能够对源代码、需求、测试、版本和缺陷数据进行描述,同时还能对这些数据之问的语义关联进行描述.通过案例分析对模型的有效性进行了讨论.

Open Collaboration within Corporations Using Software Forges

A software forge is a tool platform for collaborative software development, similar to integrated CASE environments. Unlike CASE tools, however, software forges have been designed for the software development practices of the open source community. The authors discuss their experiences using a software forge to bring open source best practices into corporations. They present the design principles and benefits of a firm-internal software forge and include a case study of how one project at SAP benefitted significantly from being on the forge.     

FinalReferencing within Code in Software Engineering Education!

Traditionally computer sciences courses will assess software code.It is common and accepted good practice(as in written reports) to reference other sources of appropriate material.However there appears to be no explicit method,recommendation or advice available to computer science tutors and students on a referencing approach! This paper aims to stimulate discussion from peers involved in software engineering education.By discussing the apparent lack of "referencing within code" advice to students and proposing suggestions for appropriate solutions.This will be based on the authors' experience of assessing code and the current advice given to their students.

Techniques for Classifying Executions of Deployed Software to Support Software Engineering Tasks

There is an increasing interest in techniques that support analysis and measurement of fielded software systems. These techniques typically deploy numerous instrumented instances of a software system, collect execution data when the instances run in the field, and analyze the remotely collected data to better understand the system's in-the-field behavior. One common need for these techniques is the ability to distinguish execution outcomes (e.g., to collect only data corresponding to some behavior or to determine how often and under which condition a specific behavior occurs). Most current approaches, however, do not perform any kind of classification of remote executions and either focus on easily observable behaviors (e.g., crashes) or assume that outcomes' classifications are externally provided (e.g., by the users). To address the limitations of existing approaches, we have developed three techniques for automatically classifying execution data as belonging to one of several classes. In this paper, we introduce our techniques and apply them to the binary classification of passing and failing behaviors. Our three techniques impose different overheads on program instances and, thus, each is appropriate for different application scenarios. We performed several empirical studies to evaluate and refine our techniques and to investigate the trade-offs among them. Our results show that 1) the first technique can build very accurate models, but requires a complete set of execution data; 2) the second technique produces slightly less accurate models, but needs only a small fraction of the total execution data; and 3) the third technique allows for even further cost reductions by building the models incrementally, but requires some sequential ordering of the software instances' instrumentation.
