Download or read book Query Planning and Optimization in Information Integration written by Oliver M. Duschka and published by . This book was released on 1997 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examine further extensions of the languages allowed for user queries and for describing information sources: disjunction, recursion and negation in source descriptions, negation and inequality in user queries. For these more expressive cases, we determine the data complexity required of languages able to represent "best possible" query plans.
Book Synopsis Quality-Driven Query Answering for Integrated Information Systems by : Felix Naumann
Download or read book Quality-Driven Query Answering for Integrated Information Systems written by Felix Naumann and published by Springer Science & Business Media. This book was released on 2002-02-27 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Internet and the World Wide Web (WWW) are becoming more and more important in our highly interconnected world as more and more data and information is made available for online access. Many individuals and governmental, commercial, cultural, and scientific organizations increasingly depend on information sources that can be accessed and queried over the Web. For example, accessing flight schedules or retrieving stock information has become common practice in todays world. When accessing this data, many people assume that the information accessed is accurate and that the data source can be accessed reliably. These two examples clearly demonstrate that not only the information content is important, the information about the quality of the data becomes an even more crucial and critical aspect for individuals and organizations when they make plans or take decisions based on the results of their queries. More precisely, having access to information of known quality becomes critical for the well-being and indeed for the functioning of modern industrialized societies. Surprisingly, despite the urgent need for clear concepts and techniques to judge and value quality and for technology to use such (meta) information, very few scientific results are known and available. Few approaches are known to use quality measures for accessing and querying information over the Web. Only a limited number of products on the IT market address this burning problem.

Book Synopsis Inconsistency Tolerance by : Leopoldo Bertossi
Download or read book Inconsistency Tolerance written by Leopoldo Bertossi and published by Springer. This book was released on 2005-01-17 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inconsistency arises in many areas in advanced computing. Often inconsistency is unwanted, for example in the specification for a plan or in sensor fusion in robotics; however, sometimes inconsistency is useful. Whether inconsistency is unwanted or useful, there is a need to develop tolerance to inconsistency in application technologies such as databases, knowledge bases, and software systems. To address this situation, inconsistency tolerance is being built on foundational technologies for identifying and analyzing inconsistency in information, for representing and reasoning with inconsistent information, for resolving inconsistent information, and for merging inconsistent information. The idea for this book arose out of a Dagstuhl Seminar on the topic held in summer 2003. The nine chapters in this first book devoted to the subject of inconsistency tolerance were carefully invited and anonymously reviewed. The book provides an exciting introduction to this new field.

Book Synopsis Adaptive Query Processing by : Amol Deshpande
Download or read book Adaptive Query Processing written by Amol Deshpande and published by Now Publishers Inc. This book was released on 2007 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive Query Processing surveys the fundamental issues, techniques, costs, and benefits of adaptive query processing. It begins with a broad overview of the field, identifying the dimensions of adaptive techniques. It then looks at the spectrum of approaches available to adapt query execution at runtime - primarily in a non-streaming context. The emphasis is on simplifying and abstracting the key concepts of each technique, rather than reproducing the full details available in the papers. The authors identify the strengths and limitations of the different techniques, demonstrate when they are most useful, and suggest possible avenues of future research. Adaptive Query Processing serves as a valuable reference for students of databases, providing a thorough survey of the area. Database researchers will benefit from a more complete point of view, including a number of approaches which they may not have focused on within the scope of their own research.

Book Synopsis Data Integration by : Michael Morris
Download or read book Data Integration written by Michael Morris and published by Springer Nature. This book was released on 2022-05-31 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data integration is a critical problem in our increasingly interconnected but inevitably heterogeneous world. There are numerous data sources available in organizational databases and on public information systems like the World Wide Web. Not surprisingly, the sources often use different vocabularies and different data structures, being created, as they are, by different people, at different times, for different purposes. The goal of data integration is to provide programmatic and human users with integrated access to multiple, heterogeneous data sources, giving each user the illusion of a single, homogeneous database designed for his or her specific need. The good news is that, in many cases, the data integration process can be automated. This book is an introduction to the problem of data integration and a rigorous account of one of the leading approaches to solving this problem, viz., the relational logic approach. Relational logic provides a theoretical framework for discussing data integration. Moreover, in many important cases, it provides algorithms for solving the problem in a computationally practical way. In many respects, relational logic does for data integration what relational algebra did for database theory several decades ago. A companion web site provides interactive demonstrations of the algorithms.

Book Synopsis Engineering Information Systems in the Internet Context by : Colette Rolland
Download or read book Engineering Information Systems in the Internet Context written by Colette Rolland and published by Springer. This book was released on 2013-11-11 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1980's, the IFIP WG8.1 conferences have provided a forum for the presentation and exchange of research results and practical experiences in the field of Information System Engineering. The WG8.1 '02 Conference is held in the beautiful Kanazawa area in North western Japan. The ubiquitous Web has revolutionised the way organisations communicate and work internally as well as externally and, consequently, the nature of information systems supporting business activities. Web-based systems have become the state of the art in information systems engineering in a very short time. As companies become more international in their strategies and activities, information systems themselves span the globe, led by the Internet. While the risks from failed systems may be enhanced due to higher expectations and increased complexity, we have the opportunity to learn more about the nature of information systems and to develop new engineering techniques and methods to improve the development of information services in a World Wide Web context. The aim theme of this working conference is "Engineering Information Systems in the Internet Context" and the programme address both technologies and methodologies for building them. x The call for the EISIC Conference was given international audience. The program committee was chosen from very well reputed researchers in the international information systems, web information systems and communication communities. Seventeen papers have been selected for presentation and discussion during the conference.
