Information Retrieval Technology
This book constitutes the refereed proceedings of the 5th Asia Information Retrieval Symposium, AIRS 2009, held in Sapporo, Japan, in October 2009. The 18 revised full papers and 20 revised poster papers presented were carefully reviewed and selected from 82 submissions. All current aspects of information retrieval - in theory and practice - are addressed; working with text, audio, image, video and multimedia data.
Linguistic Identity Matching
Regulation, risk awareness and technological advances are more and more drawing identity search requirements into business, security and data management processes. Following years of struggling with computational techniques, the new linguistic identity matching approach finally offers an appropriate way for such processes to balance the risk of missing a personal match with the costs of overmatching. The new paradigm for identity searches focuses on understanding the influences that languages, writing systems and cultural conventions have on person names. A must-read for anyone involved in the purchase, design or study of identity matching systems, this book describes how linguistic and onomastic knowledge can be used to create a more reliable and precise identity search.
Data Matching
Data matching (also known as record or data linkage, entity resolution, object identification, or field matching) is the task of identifying, matching and merging records that correspond to the same entities from several databases or even within one database. Based on research in various domains including applied statistics, health informatics, data mining, machine learning, artificial intelligence, database management, and digital libraries, significant advances have been achieved over the last decade in all aspects of the data matching process, especially on how to improve the accuracy of data matching, and its scalability to large databases. Peter Christen’s book is divided into three p...
Computers and Education
This volume contains a selection of papers on the most up-to-date experiences in the field of computers and education. It includes most relevant case studies and novel research results addressing technical and methodological aspects of computers and educations. It is relevant to researchers, practitioners, teaching staff and developers working in e-learning, computer-based education, educational software, distributed learning, lifelong learning, and open and distance learning.
Encyclopedia of E-Collaboration
"This encyclopedia provides the most comprehensive compilation of information on the design and implementation of e-collaboration technologies, their behavioral impact on individuals and groups, and theoretical considerations on links between the use of e-collaboration technology and behavioral patterns. It delivers indispensable content to libraries and researchers looking to develop programs of investigation into the use of e-collaboration"--Provided by publisher.
Media Markets in Central and Eastern Europe
This book presents a network analysis of media ownership dependencies in ten Central and Eastern European countries. In addition to a detailed description of the media landscapes in the Czech Republic, Estonia, Romania and Slovenia it furthermore gives an overview of news agencies operating in these countries. The publication is the final report of the research project "Media markets in Central and Eastern Europe - Chances of and threats against media pluralism in Europe" carried out at Danube University Krems (Austria).
Evaluation of Text Summaries Based on Linear Optimization of Content Metrics
This book provides a comprehensive discussion and new insights about linear optimization of content metrics to improve the automatic Evaluation of Text Summaries (ETS). The reader is first introduced to the background and fundamentals of the ETS. Afterward, state-of-the-art evaluation methods that require or do not require human references are described. Based on how linear optimization has improved other natural language processing tasks, we developed a new methodology based on genetic algorithms that optimize content metrics linearly. Under this optimization, we propose SECO-SEVA as an automatic evaluation metric available for research purposes. Finally, the text finishes with a consideration of directions in which automatic evaluation could be improved in the future. The information provided in this book is self-contained. Therefore, the reader does not require an exhaustive background in this area. Moreover, we consider this book the first one that deals with the ETS in depth.
