Presents a methodology for data mining and knowledge discovery in large, distributed and heterogeneous databases. In order to obtain potentially interesting patterns, relationships and rules from such large and heterogeneous data collections, it is essential that a methodology be developed to take advantage of the suite of existing methods and tools that are available for data mining and knowledge discovery in databases (KDD). One of the most important methodologies is an integration of diverse learning strategies that cooperatively performs a variety of discovery techniques that achieves high-quality knowledge. The KDLC (knowledge discovery life-cycle) model is an extended study of AqBC, which is a multi-strategy knowledge discovery approach that combines supervised inductive rule learning and unsupervised Bayesian classification via a constructive induction mechanism. A case study dealing with crop yields for a farm in the state of Idaho, USA is presented, and preliminary results are visualized by using the ArcView geographical information system (GIS). The significance of the multi-strategy knowledge discovery and visualization process in analyzing the classifications and learned rules has been empirically verified in KDLC.

This document1 contains definitions of a wide range of concepts specific to and widely used within temporal databases. In addition to providing definitions, the document also includes explanations of concepts as well as discussions of the adopted names. The consensus effort that lead to this glossary was initiated in Early 1992. Earlier versions appeared in SIGMOD Record in September 1992 and March 1994. The present glossary subsumes all the previous documents. The glossary meets the need for creating a higher degree of consensus on the definition and naming of temporal database concepts. Two sets of criteria are included. First, all included concepts were required to satisfy four relevance criteria, and, second, the naming of the concepts was resolved using a set of evaluation criteria. The concepts are grouped into three categories: concepts of general database interest, of temporal database interest, and of specialized interest. © Springer-Verlag Berlin Heidelberg 1998.

作者： Takashi Sano Wei-Tek Tsai Sanjai Rayadurgam Software Factory Department SE Technical Service and Support Division Fujitsu Limited 9-3 Nakase 1-chome Mihama-ku Chiba-city Chiba 261 Japan Software Engineering Laboratory Department of Computer Science University of Minnesota Minneapolis MN 55455 U.S.A.

In this interview, Takashi Sano reviews the origin and history of the year 2000 problem in Japan, and summarizes its status in Japan as of late 1996. He presents a way for software vendors to make this problem known to the software community because the problem is very serious, with far reaching impacts on an organization's economics, demand for talent and workforce scheduling. Then, he discusses the core techniques used at Fujitsu to tackle the year 2000 problem when a re-engineering approach is used. Finally, he provides an overview of a relevant software tool developed by Fujitsu. © 1997 John Wiley & Sons, Ltd.

An object-oriented dependency graph for program slicing 24

An object-oriented dependency graph for program slicing

24th International Conference on Technology of Object-Oriented Languages and Systems, TOOLS 1997

Program dependency graphs (PDG's) of a program facilitate program analysis and related applications such as program slicing, a method to identib the relevant entities of the program according to data and control dependencies. In the past, PDG's and program slicing were most developed for (conventional) imperative programs. Recently, the object-oriented (OO) paradigm gained momentum and popularity. The OO paradigm introduces the features of object abstraction, encapsulation, inheritance, and polymorphism to programs, but is not considered in PDG's and program slicing. In this paper, we present an Object-Oriented Dependency Graph (ODG) to represent the structure of OO programs. The ODG is defined based on a property multi-digraph that is extended from a directed graph by augmenting multiple edge types, vertex properties, and property relations. With the extension, the ODG can avoid the specious dependencies due to object encapsulation. Based on the ODG, a program slicing method for OO software is developed. Besides data and control dependencies, dependencies caused by OO features are taken into consideration in our slicing method. Through the ODG, the slicing method might be applied to facilitate understanding, debugging, and maintaining OO sojiware as well as traditional program slicing methods do. © 1998 IEEE.

software release management 6th

A poorly understood and underdeveloped part of the software process is software release management, which is the process through which software is made available to and obtained by its users. Complicating software release management is the increasing tendency for software to be constructed as a "system of systems", assembled from preexisting, independently produced, and independently released systems. Both developers and users of such software are affected by these complications. Developers need to accurately document complex and changing dependencies among the systems constituting the software. Users wilt be heavily involved in the location, retrieval, and assembly process of the systems in-order to appropriately configure the software to their particular environment. In this paper we identify the issues encountered in software release management, and present an initial set of requirements for a software release management tool. We then describe a prototype of such a tool that supports both developers and users in the software release management process. © Springer-Verlag Berlin Heidelberg 1997.

Applying static analysis to software architectures 6th

In this paper we demonstrate how static concurrency analysis techniques can be used to verify application-specific properties of an architecture description. Specifically, we use two concurrency analysis tools, INCA, a flow equation based tool, and FLAVERS, a data flow analysis based tool, to detect errors or prove properties of a WRIGHT architecture description of the gas station problem. Although both these tools are research prototypes, they illustrate the potential of static analysis for verifying that architecture descriptions adhere to important properties, for detecting problems early in the lifecycle, and for helping developers understand the changes that need to be made to satisfy the properties being analyzed. © Springer-Verlag Berlin Heidelberg 1997.

A distributed computing system consists of heterogeneous computing devices, communication networks, operating system services, and applications. As organisations move toward distributed computing environments, there will be a corresponding growth in distributed applications central to the enterprise. The design, development, and management of distributed applications presents many difficult challenges. As these systems grow to hundreds or even thousands of devices and similar or greater magnitude of software components, it will become increasingly difficult to manage them without appropriate support tools and frameworks. Further, the design and deployment of additional applications and services will be, at best, ad hoc without modelling tools and timely data on which to base design and configuration decisions. This paper presents a framework for management of distributed applications and systems. The framework is based on a set of common management services that support management activities. The services include monitoring, control, configuration, and data repository services. A prototype system built on the framework is described that implements and integrates management applications providing visualisation, fault location, performance monitoring and modelling, and configuration management. The prototype also demonstrates how various management services can be implemented.

International Symposium on software Metrics

A software quality model can make timely predictions of the class of a module, such as not fault prone or fault prone. These enable one to improve software development processes by targeting reliability improvement techniques more effectively and efficiently. Published software quality classification models generally minimize the number of misclassifications. The contribution of the paper is empirical evidence, supported by theoretical considerations, that such models can significantly benefit from minimizing the expected cost of misclassifications, rather than just the number of misclassifications. This is necessary when misclassification costs for not fault prone modules are quite different from those of fault prone modules. We illustrate the principles with a case study using nonparametric discriminant analysis. The case study examined a large subsystem of the Joint Surveillance Target Attack Radar System, JS-TARS, which is an embedded, real time, military application. Measures of the process history of each module were independent variables. Models with equal costs of misclassification were unacceptable, due to high misclassification rates for fault prone modules, but cost weighted models had acceptable, balanced misclassification rates.

In the context of GLADE, the implementation of Annex E of the Ada Reference Manual for the GNAT compiler, a transparent extension of the PCS for performing arbitrary data transforma-tions on the marshaled arguments of remote calls is presented. The concepts underlying the implementation and its implications on the configuration language are shown. A small example elucidates the chosen approach and illustrates at the same time the use of remote accesses to class-wide types for implementing distributed objects in Ada 95. © 1997 ACM.

Workshop on Knowledge and Data engineering Exchange

作者： J. Lee L.F. Lai Yu Fei S.J. Yang W.T. Huang Software Engineering Laboratory Department of Computer Science and Information Engineering National Central University Chungli Taiwan

Proposes an approach to reusing requirements specifications, called "task-based specifications in conceptual graphs" (TBCG). In TBCG, the task-based specification methodology is used to serve as the mechanism to structure the knowledge captured in conceptual models, and conceptual graphs are adopted as the formalism to express the requirements specification. TBCG provides several mechanisms to facilitate the reuse of formal specifications: (i) a contextual retrieval mechanism to support context-sensitive specification retrieval and incremental context acquisition, (ii) a graph matching mechanism to compute the similarity between two graphs based on semantic matching and fuzzy logic, and (iii) a paraphraser to serve as an explanation mechanism for the retrieved specifications.
