Download or read book Fundamentals of Database Indexing and Searching written by Arnab Bhattacharya and published by CRC Press. This book was released on 2014-12-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Database Indexing and Searching presents well-known database searching and indexing techniques. It focuses on similarity search queries, showing how to use distance functions to measure the notion of dissimilarity. After defining database queries and similarity search queries, the book organizes the most common and representative index structures according to their characteristics. The author first describes low-dimensional index structures, memory-based index structures, and hierarchical disk-based index structures. He then outlines useful distance measures and index structures that use the distance information to efficiently solve similarity search queries. Focusing on the difficult dimensionality phenomenon, he also presents several indexing methods that specifically deal with high-dimensional spaces. In addition, the book covers data reduction techniques, including embedding, various data transforms, and histograms. Through numerous real-world examples, this book explores how to effectively index and search for information in large collections of data. Requiring only a basic computer science background, it is accessible to practitioners and advanced undergraduate students.
Download or read book Semantic Models for Multimedia Database Searching and Browsing written by Shu-Ching Chen and published by Springer Science & Business Media. This book was released on 2005-12-08 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semantic Models for Multimedia Database Searching and Browsing begins with the introduction of multimedia information applications, the need for the development of the multimedia database management systems (MDBMSs), and the important issues and challenges of multimedia systems. The temporal relations, the spatial relations, the spatio-temporal relations, and several semantic models for multimedia information systems are also introduced. In addition, this book discusses recent advances in multimedia database searching and multimedia database browsing. More specifically, issues such as image/video segmentation, motion detection, object tracking, object recognition, knowledge-based event modeling, content-based retrieval, and key frame selections are presented for the first time in a single book. Two case studies consisting of two semantic models are included in the book to illustrate how to use semantic models to design multimedia information systems. Semantic Models for Multimedia Database Searching and Browsing is an excellent reference and can be used in advanced level courses for researchers, scientists, industry professionals, software engineers, students, and general readers who are interested in the issues, challenges, and ideas underlying the current practice of multimedia presentation, multimedia database searching, and multimedia browsing in multimedia information systems.

Download or read book Computerized Literature Searching written by Charles L. Gilreath and published by Routledge. This book was released on 2019-03-04 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The computer terminal is well on its way to being as commonplace as the telephone, and its usefulness to the scholar and scientist is so great that already computer screens and disks are seen frequently in academic offices. The value of computers in research is well established, with vast amounts of data being processed daily by all sizes of computers. Computers also have had dramatic effects on the researcher's literature-searching options: Scientists and scholars can now query enormous databases containing tens of millions of citations to published literature and can extract bibliographies tailored to their specific questions. The power and flexibility afforded the user of information by these literature-searching systems ease the burden of library work, but in order to use the systems effectively, it is necessary to understand both their capabilities and their limitations. Mr. Gilreath describes the principles underlying online bibliographic systems, the databases available, and the factors a researcher must consider in using them. He explores in some depth the relationship of the structure and terminology of publications in various fields to the literature-searching process and provides detailed guidelines for research in the life, health, agricultural, and social sciences, chemistry, physics, mathematics, geology, meteorology, engineering, education, psychology, business, law, current affairs, and the humanities. A glossary of literature-searching terms is included.

Download or read book Keyword Search in Databases written by Jeffrey Xu Yu and published by Springer Nature. This book was released on 2022-06-01 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become highly desirable to provide users with flexible ways to query/search information over databases as simple as keyword search like Google search. This book surveys the recent developments on keyword search over databases, and focuses on finding structural information among objects in a database using a set of keywords. Such structural information to be returned can be either trees or subgraphs representing how the objects, that contain the required keywords, are interconnected in a relational database or in an XML database. The structural keyword search is completely different from finding documents that contain all the user-given keywords. The former focuses on the interconnected object structures, whereas the latter focuses on the object content. The book is organized as follows. In Chapter 1, we highlight the main research issues on the structural keyword search in different contexts. In Chapter 2, we focus on supporting structural keyword search in a relational database management system using the SQL query language. We concentrate on how to generate a set of SQL queries that can find all the structural information among records in a relational database completely, and how to evaluate the generated set of SQL queries efficiently. In Chapter 3, we discuss graph algorithms for structural keyword search by treating an entire relational database as a large data graph. In Chapter 4, we discuss structural keyword search in a large tree-structured XML database. In Chapter 5, we highlight several interesting research issues regarding keyword search on databases. The book can be used as either an extended survey for people who are interested in the structural keyword search or a reference book for a postgraduate course on the related topics. Table of Contents: Introduction / Schema-Based Keyword Search on Relational Databases / Graph-Based Keyword Search / Keyword Search in XML Databases / Other Topics for Keyword Search on Databases

Book excerpt: "....a well-written, quick read perfect for medical librarianship students, physicians, and researchers or anyone interested in improving their MEDLINE searching abilities." -- Journal of the Medical Library Association This concise and clearly written book will make your PubMed searches more productive. This completely revised second edition of Brian Katcher's MEDLINE: a guide to effective searching in PubMed and other interfaces promotes the cultivation of an informed and thoughtful approach to searching in PubMed/MEDLINE and other interfaces to MEDLINE. MEDLINE, the National Library of Medicine's on-line bibliographic database, is the premiere index to the world's biomedical literature. It is the primary component of PubMed. MEDLINE is exquisitely organized: each journal article is manually indexed under an average of a dozen Medical Subject Headings (MeSH Terms), one or more publication types, and more. An understanding of this organization is essential to effective searching. Any health professional, health sciences student, or researcher will benefit from reading this book. It explains the basics of formulating searches, shows how to put the main indexing elements in MEDLINE to best use, illustrates the importance of Medical Subject Headings (MeSH), provides guidance for framing questions, and backs everything up with practical examples. MEDLINE: a guide to effective searching in PubMed and other interfaces is an essential resource for those concerned with evidence-based medicine and those engaged in biomedical research. Medical librarians and teachers of medical informatics will find this book to be useful in promoting the careful use of PubMed/MEDLINE. Sometimes simply reading a linear narrative--even on a screen--is a good way to learn. In addition, PubMed offers excellent on-line tutorials.
