Research report prepared for OCLC on multidimensional mapping of libraries based on shared holdings in the OCLC Online Union Catalog by William E McGrath( )

3 editions published in 1983 in English and held by 59 WorldCat member libraries worldwide

How many books does a group of libraries have in common? Pre-OCLC days, the question was simple and the answer vital. If a large number were held in common, there would be a compelling argument for computerized bibliographic databases for shared cataloging and interlibrary loan. "Overlap" studies did provide argument, and the rest is history
FRBR work-set algorithm : version 2.0 by Thomas Butler Hickey( )

2 editions published between 2005 and 2009 in English and held by 45 WorldCat member libraries worldwide

"The research work-set algorithm generates a key for each bibliographic record. These FRBR keys can then be used to bring work-sets together. The current algorithm ignores format so that the generated work-sets are sometimes at a higher level than a FRBR work. A work-set is a group of bibliographic records having the same FRBR key, generated according to the algorithm in this paper."--Page 3
Research report on field, subfield, and indicator statistics in OCLC bibliographic records by Thomas Butler Hickey( )

8 editions published between 1900 and 1981 in English and held by 38 WorldCat member libraries worldwide

The statistics that are presented are based on a one percent systematic sample of the oclc online union catalog as of January 1980. Detailed data were collected on the use of fields, subfields, indicators in bibliographic records, and on the co-occurrence of fields within bibliographic records. The sample used for the study was obtained by extracting all records with an oclc control number ending in 44. For each category of this report, the statistics are grouped by format: monographs, serials, audiovisuals, sound recordings, music scores, maps, manuscripts, and cumulative bibliographic files. These statistics should be useful for estimating file growth, selecting subsets of records for local catalogs, and for designing bibliographic record data bases. (Author/RAA)
Research report on development of a probabilistic author search and matching technique for retrieval and creation of bibliographic records by Thomas Butler Hickey( )

8 editions published between 1981 and 1982 in English and held by 35 WorldCat member libraries worldwide

Using macro and micro-structure analysis of large files of personal author names, this study developed retrieval techniques and algorithms to automatically correct and/or flag typographical errors in names, identify names in a database that are similar to a name entered by a user during a search, and measure similarities between names. It was found that personal names have very different characteristics than English language words, and this project demonstrated that useful displays for human verification of author names can be built, although at some computational expense. Automatic correction of errors, requiring greater computation, was not demonstrated by the project; however, such correction seems feasible with extensions of the techniques developed for automatic detection. A bibliography of 39 titles is included. (Author/RAA)
Superimposed coding versus sequential and inverted files by Thomas Butler Hickey( )

15 editions published between 1976 and 1977 in English and held by 31 WorldCat member libraries worldwide

The relative efficiency of three computer search algorithms was compared for searching large bibliographic files with Boolean search strategies. The sequential and inverted files represent the two most common file structures used today for bibliographic searching. Superimposed coding is an alternative that is becoming more attractive as the speed of computers improves. The superimposed search has a key associated with each record in the data base to act as a screen to eliminate the majority of records from further consideration. The keys are based on the bigrams and trigrams contained in the record, and are arranged in a linear file. The sequential search is a character by character scan of the entire file. This search is facilitated by constructing a finite state machine at the beginning of the search to match the search terms. The inverted file is fairly standard, except for the use of bit vectors to hold the postings of very common entries. A data base of 100,000 INSPEC records, from nine months of 1974, was used for testing the algorithms with 339 real-life search questions
Registering researchers in authority files by Karen Smith-Yoshimura( )

2 editions published in 2014 in English and held by 28 WorldCat member libraries worldwide

The Registering Researchers in Authority Files Task Group has examined a range of researcher registration and profiling services. A number of approaches to providing authoritative researcher IDs have emerged, but they tend to be limited by discipline, affiliation, or publisher. The Task Group developed use cases and functional requirements for researcher ID management systems and then compared the functional requirements against a sample of currently available systems to identify gaps, challenges and opportunities. A key objective of this work was to understand how the various types of researcher ID schemes can be leveraged to support improved discoverability of research output for individual authors and institutions
Multidimensional mapping of libraries based on shared holdings in the OCLC online union catalog by William E McGrath( Book )

Using the OAI-PMH--differently by Herbert van de Sompel( )

1 edition published in 2003 in English and held by 4 WorldCat member libraries worldwide

The Open Archives Initiative's Protocol for Metadata Harvesting (OAI-PMH) was created to facilitate discovery of distributed resources. The OAI-PMH achieves this by providing a simple, yet powerful framework for metadata harvesting. Harvesters can incrementally gather records contained in OAI-PMH repositories and use them to create services covering the content of several repositories. The OAI-PMH has been widely accepted, and until recently, it has mainly been applied to make Dublin Core metadata about scholarly objects contained in distributed repositories searchable through a single user interface. This article describes innovative applications of the OAI-PMH that we have introduced in recent projects. In these projects, OAI-PMH concepts such as resource and metadata format have been interpreted in novel ways. The result of doing so illustrates the usefulness of the OAI-PMH beyond the typical resource discovery using Dublin Core metadata. Also, through the inclusion of XSL1 stylesheets in protocol responses, OAI-PMH repositories have been directly overlaid with an interface that allows users to navigate the contained metadata by means of a Web browser. In addition, through the introduction of PURL2 partial redirects, complex OAI-PMH protocol requests have been turned into simple URIs that can more easily be published and used in downstream applications
Experiments with the IFLA functional requirements for bibliographic records (FRBR) by Thomas Butler Hickey( )

1 edition published in 2002 in English and held by 3 WorldCat member libraries worldwide

OCLC is investigating how best to implement IFLA's Functional Requirements for Bibliographic Records (FRBR). As part of that work we have undertaken a series of experiments with algorithms to group existing bibliographic records into works and expressions. Working with both subsets of records and the whole WorldCat database, the algorithm we developed achieved reasonable success identifying all manifestations of a work

A Java Z39.50 client for browsing large databases by Thomas Butler Hickey( )

1 edition published in 1998 in English and held by 2 WorldCat member libraries worldwide

Web browsers have become the method of choice for access to bibliographic databases, almost entirely replacing proprietary clients for new end-user systems. Going one step further and programming the client in Java to run within the browser, rather than relying entirely on HTML, opens up a new level of functionality. SecondSearch is an experimental system under development to explore both performance and functionality issues of this approach. It uses a tree structure to display a hierarchical view of records, giving the user the ability to zoom in and out of sections of the selected databases. The system is designed to be scalable to thousands of users browsing and searching hundreds of millions of records. A major challenge has been to create an interface that is simple, powerful, does not place an exorbitant load on the server, and is suitable for dozens of databases, each containing millions of records
Multidimensional Mapping of Libraries Based on Shared Holdings in the Oclc Online Union Catalog. Research Report by William E McGrath( Book )

1 edition published in 1983 in English and held by 2 WorldCat member libraries worldwide

This report describes the multidimensional scaling (mds) method for interpreting collection overlap based on the number of books held by pairs of libraries in large groups (as many as 100 libraries or more). Mds results for four groups of libraries sampled from the oclc database are also presented. Mds is described as a class of data-analytic or descriptive techniques designed to uncover the structure of a database in terms of clusters of similar objects within one or more dimensions. It is reported that (1) in the first group of libraries studied (a random sample of 60 network libraries), public and academic libraries separated in two dimensions; (2) in a random sample of 50 academic libraries, types of libraries (law, medical, college, university, and denominational) separated in two dimensions; (3) a random sample of 100 libraries without regard to type, nevertheless clustered in two dimensions by library type (university, college, public, denominational, medical, and special); and (4) a random sample of 50 public libraries had tentative clusters not yet identified. The implications of these findings are discussed for cooperative collection development, interlibrary lending, partitioning of the oclc database by type of library, and library network relationships. A 22-item bibliography and lists of the libraries included in the study are also provided. (Author/ESR)
Metadata switch : thinking about some metadata management and knowledge organization issues in the changing research and learning landscape by Lorcan Dempsey( )

1 edition published in 2005 in English and held by 2 WorldCat member libraries worldwide

The academic library is not an end in itself. It supports research, learning and scholarship, and it must adapt as research and learning behaviors change in a network environment. The papers in this volume give a good sense of the challenges posed by such developments and the manifold library response. This paper briefly considers some of these issues, and takes them as its context, but quickly moves to a very specific emphasis. It considers how such library responses create new metadata management and knowledge organization questions, and it then outlines some of the work in OCLC Research which responds to these issues

Present and future capabilities of the online journal by Thomas Butler Hickey( )

1 edition published in 1995 in English and held by 2 WorldCat member libraries worldwide

Electronic versions of traditional paper journals offer a number of advantages, most of which have been more than offset by the electronic journals' disadvantages. Advances in computing developed primary for the office environment are reducing the technical disadvantages to the point where electronic formats are rapidly approaching parity of ease of use and convenience with paper. -- Electronic journals are currently being developed in three main formats : simple text, page image, and structured text. Each of these formats has its own strenghts and weakness, and there are some combinations of the three that offer interesting capabilities. -- Automation is often described as automating what we currently do, which in turn changes what we do, resulting in another generation of automation. In many ways, changing what we do occurs simultaneously with the automation of an activity as users of information develop new ways to use the electronic medium. The role traditional journals play

The role of classification in CORC by Thomas Butler Hickey( )

2 editions published in 1999 in English and held by 2 WorldCat member libraries worldwide

The use of the DDC in metadata offers unique opportunities for organizing and searching Web resources. In this paper, we describe CORC tools for applying and using the DDC as a metadata element. Both the CORC system and the DDC are benefiting from the inclusion of Dewey in the CORC project. CORC benefits from having integrated access to a rich classification system that can be used to organize its metadata; the DDC benefits from its inclusion in an easily adaptable Web-based system that facilitates the exploration of what a classification system can do in this new environment
