Mutation Operators for Spreadsheets

Based on (1) research into mutation testing for general purpose programming languages, and (2) spreadsheet errors that have been reported in the literature, we have developed a suite of mutation operators for spreadsheets. We present an evaluation of the mutation adequacy of du-adequate test suites generated by a constraint-based automatic test-case generation system we have developed in previous work. The results of the evaluation suggest additional constraints that can be incorporated into the system to target mutation adequacy. In addition to being useful in mutation testing of spreadsheets, the operators can be used in the evaluation of error-detection tools and also for seeding spreadsheets with errors for empirical studies. We describe two case studies where the suite of mutation operators helped us carry out such empirical evaluations. The main contribution of this paper is a suite of mutation operators for spreadsheets that can be used for carrying out empirical evaluations of spreadsheet tools to indicate ways in which the tools can be improved.     

Knowledge Based Software Engineering for Software Development

Information revolution means that the software such as MIS developed by software engineers must be capable of rapid adaptation to constantly changing circumstances and demands in order to remain capable of effectively fulfilling their missions. The key to achieve these goals is to maintain an update understanding of the workers＇ requirements, how well thcse are currently met, and how well current and future needs might be met by conceivable solution options. This paper proposes an engineering approach of knowledge based software systems for the development and evolution of software systems. This approach captures the changing requirements of the works, together with the details of the solutions that are intended to meet them, in a repository.     

The Need for Software Engineering

Early in this decade a set of programming practices began to appear that seemed to offer a way out of the software difficulties accompanying the development of large systems. These practices, developed by Brooks,1 Baker,2 Dijkstra,3 Mills,4,5 and others, included structured programming, top-down development, chief programmer teams, HIPO (hierarchy/input-process-output) documentation, development support library, and structured walk-throughs. But despite the increasing amount of software development ment and its rising cost relative to the defense budget, corporation expenditures, and even the gross national product, the new programming techniques have not been adopted by acclamation. McClure,6 surveying the scene at COMPCON '76 Spring, saw "the great masses of programmers conducting their business exactly as they did five years ago." Nor was there the slightest sign in McClure's 5-year projection of "strong winds of change." His intuition was later supported by a survey of major Los Angeles area corporations,7 which concluded that, for all the fanfare, "the techniques are simply not widely used."     

Data Mining for Software Engineering

To improve software productivity and quality, software engineers are increasingly applying data mining algorithms to various software engineering tasks. However, mining SE data poses several challenges. The authors present various algorithms to effectively mine sequences, graphs, and text from such data.     

Strategies for Software Engineering Implementation

Software Engineering for User Interfaces

The discipline of software engineering can be extended in a natural way to deal with the issues raised by a systematic approach to the design of human-machine interfaces. Two main points are made: that the user should be treated as part of the system being designed, and that projects should be organized to take account of the current (small) state of a priori knowledge about how to design interfaces.

Frame technology adapts generic components into custom information structures. Its facility for maximizing reuse and minimizing redundancy has demonstrated dramatic improvements across software's life cycle.     

Web-Based Support for Cooperative Software Engineering

The Tatami project is building a system to support software engineering over the internet, exploiting recent advances in Web technology, interface design, and specification. Our effort to improve the usability of such systems has led us into algebraic semiotics, while our effort to develop better formal methods for distributed concurrent systems has led us into hidden algebra and fuzzy logic. This paper discusses the Tatami system design, especially its software architecture, and its user interface principles. New work in the latter area includes an extension of algebraic semiotics to dynamic multimedia interfaces, and integrating Gibsonian affordances with algebraic semiotics.     

XML-Based Hypertext Functionalities for Software Engineering

Hypertext functionalities represent a form of the distilled wisdom of the hypermedia community. Even if they were introduced and advocated already in the pre-Web era, most of these functionalities are absent in current Web browsers. However, such functionalities can be very useful in some specific applicative fields, like for instance browsing complex software engineering documents, using standard WWW components. We propose to exploit the advent of XML as a basic infrastructure for describing software engineering hypertexts. In fact, we describe XMLC, a prototype of an XML browser that, given its modular architecture and general scope, can be seen as the basis for implementing sophisticated hypertext functionalities for software engineering documentation to be maintained and browsed on the Web.

Development of a Software Engineering Ontology for Multisite Software Development

This paper aims to present an ontology model of software engineering to represent its knowledge. The fundamental knowledge relating to software engineering is well described in the textbook entitled Software Engineering by Sommerville that is now in its eighth edition [1] and the white paper, Software Engineering Body of Knowledge (SWEBOK), by the IEEE [2] upon which software engineering ontology is based. This paper gives an analysis of what software engineering ontology is, what it consists of, and what it is used for in the form of usage example scenarios. The usage scenarios presented in this paper highlight the characteristics of the software engineering ontology. The software engineering ontology assists in defining information for the exchange of semantic project information and is used as a communication framework. Its users are software engineers sharing domain knowledge as well as instance knowledge of software engineering.
