Introduction to Information Retrieval


Book Description

Class-tested and coherent, this textbook teaches classical and web information retrieval, including web search and the related areas of text classification and text clustering from basic concepts. It gives an up-to-date treatment of all aspects of the design and implementation of systems for gathering, indexing, and searching documents; methods for evaluating systems; and an introduction to the use of machine learning methods on text collections. All the important ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students in computer science. Based on feedback from extensive classroom experience, the book has been carefully structured in order to make teaching more natural and effective. Slides and additional exercises (with solutions for lecturers) are also available through the book's supporting website to help course instructors prepare their lectures.




Test Collection Based Evaluation of Information Retrieval Systems


Book Description

Use of test collections and evaluation measures to assess the effectiveness of information retrieval systems has its origins in work dating back to the early 1950s. Across the nearly 60 years since that work started, use of test collections is a de facto standard of evaluation. This monograph surveys the research conducted and explains the methods and measures devised for evaluation of retrieval systems, including a detailed look at the use of statistical significance testing in retrieval experimentation. This monograph reviews more recent examinations of the validity of the test collection approach and evaluation measures as well as outlining trends in current research exploiting query logs and live labs. At its core, the modern-day test collection is little different from the structures that the pioneering researchers in the 1950s and 1960s conceived of. This tutorial and review shows that despite its age, this long-standing evaluation method is still a highly valued tool for retrieval research.




Overview of the Third Text REtrieval Conference (TREC-3)


Book Description

Held in Gaithersburg, MD, August November 2-4, 1994. The conference was co-sponsored by the National Inst. of Standards and Technology (NIST) and the Advanced Research Projects Agency (ARPA) and was attended by 150 people involved in the 32 participating groups. Evaluates new technologies in text retrieval. Includes 34 papers: indexing structures, fragmentation schemes, probabilistic retrieval, latent semantic indexing, interactive document retrieval, and much more. Numerous graphs, tables and charts.




Opinion Mining and Sentiment Analysis


Book Description

This survey covers techniques and approaches that promise to directly enable opinion-oriented information-seeking systems.




The Adaptive Web


Book Description

This state-of-the-art survey provides a systematic overview of the ideas and techniques of the adaptive Web and serves as a central source of information for researchers, practitioners, and students. The volume constitutes a comprehensive and carefully planned collection of chapters that map out the most important areas of the adaptive Web, each solicited from the experts and leaders in the field.
