Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - Evaluation has always played a major role in information retrieval, with the early pioneers such as Cyril Cleverdon and Gerard Salton laying the foundations for most of the evaluation methodologies in use today. The retrieval community has been extremely fortunate to have such a well-grounded evaluation paradigm during a period when most of the human language technologies were just developing. This lecture has the goal of explaining where these evaluation methodologies came from and how they have continued to adapt to the vastly changed environment in the search engine world today. The lecture starts with a discussion of the early evaluation of information retrieval systems, starting with the Cranfield testing in the early 1960s, continuing with the Lancaster 'user' study for MEDLARS, and presenting the various test collection investigations by the SMART project and by groups in Britain. The emphasis in this chapter is on the how and the why of the various methodologies developed. Thesecond chapter covers the more recent 'batch' evaluations, examining the methodologies used in the various open evaluation campaigns such as TREC, NTCIR (emphasis on Asian languages), CLEF (emphasis on European languages), INEX (emphasis on semi-structured data), etc. Here again the focus is on the how and why, and in particular on the evolving of the older evaluation methodologies to handle new information access techniques. This includes how the test collection techniques were modified and how the metrics were changed to better reflect operational environments. The final chapters look at evaluation issues in user studies -- the interactive part of information retrieval, including a look at the search log studies mainly done by the commercial search engines. Here the goal is to show, via case studies, how the high-level issues of experimental design affect the final evaluations. Table of Contents: Introduction and Early History / 'Batch' Evaluation Since 1992 / Interactive Evaluation/ Conclusion.…

Condición: Sehr gut. Zustand: Sehr gut | Sprache: Englisch | Produktart: Bücher | Information Retrieval is at the core of our daily lives. Modern search, ranking and indexing systems underpinned by enhanced computing power, fast network speeds and near unlimited data storage capacity mean we have easy access to all the information we need, when we need it. Yet the principles upon which this modern technology based date back to before the 1960s. In this concise history of the early years of Information Retrieval, Donna Harman, one of the pioneers of the field, provides the reader with a plethora of insights into the important work that led us to where we are today. Written in a chronological order and in a manner that presents the technical context, the research and the early commercialization efforts, it lays out how each contribution built on what went before. The reader is offered a text that is not only a delight to read, but is also insightful in the way the technologies evolve as computing power increases. Information Retrieval: The Early Years will be of interest to everyone with an interest in understanding the foundations of the science behind search engines.…
