This book was released on 1989 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In modern retrieval environments, collection searches are normally conducted on-line under user control. Iterative collection searches can then be performed where tentative queries are initially processed, to be successively improved and refined during the search process. When searches are carried out directly by the users, classified document organizations are especially useful, because collection browsing becomes possible, and access is provided to complete groups of related documents. The state-of-the-art in automatic document classification is summarized in the present study, and evaluation data are provided to demonstrate the effectiveness and efficiency of clustered file search operations."

Download or read book Introduction to Information Retrieval written by Christopher D. Manning and published by Cambridge University Press. This book was released on 2008-07-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Clustering and Information Retrieval written by Weili Wu and published by Springer Science & Business Media. This book was released on 2003-11-30 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clustering is an important technique for discovering relatively dense sub-regions or sub-spaces of a multi-dimension data distribution. Clus tering has been used in information retrieval for many different purposes, such as query expansion, document grouping, document indexing, and visualization of search results. In this book, we address issues of cluster ing algorithms, evaluation methodologies, applications, and architectures for information retrieval. The first two chapters discuss clustering algorithms. The chapter from Baeza-Yates et al. describes a clustering method for a general metric space which is a common model of data relevant to information retrieval. The chapter by Guha, Rastogi, and Shim presents a survey as well as detailed discussion of two clustering algorithms: CURE and ROCK for numeric data and categorical data respectively. Evaluation methodologies are addressed in the next two chapters. Ertoz et al. demonstrate the use of text retrieval benchmarks, such as TRECS, to evaluate clustering algorithms. He et al. provide objective measures of clustering quality in their chapter. Applications of clustering methods to information retrieval is ad dressed in the next four chapters. Chu et al. and Noel et al. explore feature selection using word stems, phrases, and link associations for document clustering and indexing. Wen et al. and Sung et al. discuss applications of clustering to user queries and data cleansing. Finally, we consider the problem of designing architectures for infor mation retrieval. Crichton, Hughes, and Kelly elaborate on the devel opment of a scientific data system architecture for information retrieval.
Download or read book Fuzzy Sets in Information Retrieval and Cluster Analysis written by S. Miyamoto and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph intends to establish a solid link among three fields: fuzzy set theory, information retrieval, and cluster analysis. Fuzzy set theory supplies new concepts and methods for the other two fields, and provides a common frame work within which they can be reorganized. Four principal groups of readers are assumed: researchers or students who are interested in (a) application of fuzzy sets, (b) theory of information retrieval or bibliographic databases, (c) hierarchical clustering, and (d) application of methods in systems science. Readers in group (a) may notice that the fuzzy set theory used here is very simple, since only finite sets are dealt with. This simplification enables the max min algebra to deal with fuzzy relations and matrices as equivalent entities. Fuzzy graphs are also used for describing theoretical properties of fuzzy relations. This assumption of finite sets is sufficient for applying fuzzy sets to information retrieval and cluster analysis. This means that little theory, beyond the basic theory of fuzzy sets, is required. Although readers in group (b) with little background in the theory of fuzzy sets may have difficulty with a few sections, they will also find enough in this monograph to support an intuitive grasp of this new concept of fuzzy information retrieval. Chapter 4 provides fuzzy retrieval without the use of mathematical symbols. Also, fuzzy graphs will serve as an aid to the intuitive understanding of fuzzy relations.
Download or read book An Interactive Information Organization and Retrieval System in a Time sharing Environment written by Mehdi Baghebanzadeh Kermani and published by . This book was released on 1969 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of the formatted file organization and retrieval systems, in particular, the scatter indexing methods, were the major part of the formatted systems which are investigated. The upper bound of such an index file using single and multiple attribute queries is studied and obtained. In the general file systems, the study begins with the investigation of some of the existing systems, leads to some possible improvement observations, and finally results in the projection-angle (PRANG) clustering technique. This method of clustering partitions the process into two individual processes and associates records according to joint similarity and simultaneously makes it easier to locate the proper cluster in the retrieval phase. An operating system for this method using the TSS 940 time-sharing computer system at the Berkeley campus is implemented and the results of such a system for two data bases are studied. The Prang system is able to produce clusters for such data bases and thus organize proper information retrieval systems. The retrieval of the system results in orderly related records of the file with an associating factor for the retrieved records. (Author).
