1O'Neill, E.T. ; Kammerer, K.A. ; Bennett, R.: ¬The aboutness of words.
In: Journal of the Association for Information Science and Technology. 68(2017) no.10, S.2471-2483.
Abstract: Word aboutness is defined as the relationship between words and subjects associated with them. An aboutness coefficient is developed to estimate the strength of the aboutness relationship. Words that are randomly distributed across subjects are assumed to lack aboutness and the degree to which their usage deviates from a random pattern indicates the strength of the aboutness. To estimate aboutness, title words and their associated subjects are extracted from the titles of non-fiction English language books in the OCLC WorldCat database. The usage patterns of the title words are analyzed and used to compute aboutness coefficients for each of the common title words. Words with low aboutness coefficients (An and In) are commonly found in stop word lists, whereas words with high aboutness coefficients (Carbonate, Autism) are unambiguous and have a strong subject association. The aboutness coefficient potentially can enhance indexing, advance authority control, and improve retrieval.

2O'Neill, E.T. ; Bennett, R. ; Kammerer, K.: Using authorities to improve subject searches.
In: Cataloging and classification quarterly. 52(2014) no.1, S.6-19.
Abstract: Authority files have played an important role in improving the quality of indexing and subject cataloging. Although authorities can significantly improve searching by increasing the number of access points, they are rarely an integral part of the information retrieval process, particularly end-users' searches. A retrieval prototype, searchFAST, was developed to test the feasibility of using an authority file as an index to bibliographic records. searchFAST uses Faceted Application of Subject Terminology (FAST) as an index to OCLC's WorldCat.org bibliographic database. The searchFAST prototype complements, rather than replaces, existing WorldCat.org access. The bibliographic file is searched indirectly; first the authority file is searched to identify appropriate subject headings, then the headings are used to retrieve the matching bibliographic records. The prototype demonstrates the effectiveness and practicality of using an authority file as an index. Searching the authority file leverages authority control work by increasing the number of access points while supporting a simple interface designed for end-users.

4Zumer, M. ; O'Neill, E.T.: Modeling aggregates in FRBR.
In: Cataloging and classification quarterly. 50(2012) no.5/7, S.456-472.
Abstract: In the bibliographic environment, the term aggregate is used to describe a bibliographic entity formed by combining distinct bibliographic units together. Aggregates are a large and growing class of information resources-up to twenty percent of the bibliographic records in OCLC's WorldCat may represent aggregates. The Functional Requirements for Bibliographic Records: Final Report only briefly references aggregates. Difficulties and inconsistencies in the application of the FRBR model to aggregates have been identified as a significant impediment to FRBR implementation. To address the issue, the FRBR Review Group established a Working Group on Aggregates which completed its charge and submitted its final report in 2011. The Working Group proposed that an aggregate be defined as a "manifestation embodying multiple distinct expressions". This paper examines the proposed definition and explores how aggregates can be modeled.

In: Journal of the American Society for Information Science and Technology. 59(2008) no.13, S.2042-2050.
Abstract: WorldCat, OCLC's bibliographic database, identifies books and the libraries that hold them. The holdings provide detailed information about the type and number of libraries that have acquired the material. Using this information, it is possible to infer the type of audience for which the material is intended. A quantitative measure, the audience level, is derived from the types of libraries that have selected the resource. The audience level can be used to refine discovery, analyze collections, advise readers, and enhance reference services.
6O'Neill, E.T. ; Chan, L.M.: FAST - a new approach to controlled subject access.
In: New pespectives on subject indexing and classification: essays in honour of Magda Heiner-Freiling. Red.: K. Knull-Schlomann, u.a. Leipzig : Deutsche Nationalbibliothek, 2008. S.173-177.
Abstract: Recent trends, driven to a large extent by the rapid proliferation of digital resources, are forcing changes in bibliographic control to make it easier to use, understand, and apply subject data. Subject headings are no exception. The enormous volume and rapid growth of digital libraries and repositories and the emergence of numerous metadata schemes have spurred a reexamination of the way subject data are to be provided for such resources efficiently and effectively. To address this need, OCLC in cooperation with the Library of Congress, has taken a new approach, called FAST (Faceted Application of Subject Terminology). FAST headings are based on the existing vocabulary in Library of Congress Subject Headings (LCSH), but are applied with a simpler syntax than required by Library of Congress application policies. Adapting the LCSH vocabulary in a simplified faceted syntax retains the rich vocabulary of LCSH while making it easier to understand, control, apply, and use.

In: Library resources and technical services. 51(2007) no.2, S.106-115.
Abstract: Digital materials are reshaping library collections and, by extension, traditional library practice for collecting, organizing, and preserving information. This paper uses OCLC's WorldCat bibliographic database as a data source for examining questions relating to digital materials in library collections, including criteria for identifying digital materials algorithmically in MARC21 records; the quantity, types, characteristics, and holdings patterns of digital materials cataloged in WorldCat; and trends in WorldCat cataloging activity for digital materials over time. Issues pertaining to cataloging practice for digital materials and perspectives on digital holdings at the work level also are discussed. Analysis of the aggregate collection represented by the combined digital holdings in WorldCat affords a high-level perspective on historical patterns, suggests future trends, and supplies useful intelligence with which to inform decision making in a variety of areas.
9Hickey, T.B. ; Toves, J. ; O'Neill, E.T.: NACO normalization : a detailed examination of the authority file comparison rules.
In: Library resources and technical services. 50(2006) no.3, S.166-172.
Abstract: Normalization rules are essential for interoperability between bibliographic systems. In the process of working with Name Authority Cooperative Program (NACO) authority files to match records with Functional Requirements for Bibliographic Records (FRBR) and developing the Faceted Application of Subject Terminology (FAST) subject heading schema, the authors found inconsistencies in independently created NACO normalization implementations. Investigating these, the authors found ambiguities in the NACO standard that need resolution, and came to conclusions on how the procedure could be simplified with little impact on matching headings. To encourage others to test their software for compliance with the current rules, the authors have established a Web site that has test files and interactive services showing their current implementation.
10Patton, G. ; Hengel-Dittrich, C. ; O'Neill, E.T. ; Tillett, B.B.: VIAF (Virtual International Authority File) : Linking Die Deutsche Bibliothek and Library of Congress Name Authority Files.
Abstract: Die Deutsche Bibliothek, the Library of Congress, and OCLC Online Computer Library Center are jointly developing a virtual international authority file (VIAF) for personal names which links authority records from the world's national bibliographic agencies and will be made freely available on the Web. The goals of the project are to prove the viability of automatically linking authority records from different national authority files and to demonstrate its benefits. The authority and bibliographic files from the Library of Congress and Die Deutsche Bibliothek were used to create the initial VIAF which contains over six million names with over a half million links. A key aspect of the project was the development of automated name matching algorithms which use information from both authority records and the corresponding bibliographic records. The practicality of algorithmically linking the personal names between national authority files was demonstrated; seventy percent of the authority records for personal names common to both files were automatically linked with an error rate of less than one percent. The long-term goal of the VIAF project is to combine the authoritative names from many national libraries and other significant sources into a shared global authority service.

11O'Neill, E.T.: OCLC's experience identifying and using works.
Inhalt: Beitrag anlässlich des FRBR-Workshops für Expertengruppenmitglieder am 8. und 9. Juli 2004 in Der Deutschen Bibliothek mit der Zielsetzung: Die Functional Requirements for Bibliographic Records (FRBR) haben seit ihrer Veröffentlichung 1998 durch die IFLA die bibliothekarische Diskussion befruchtet. Was verbirgt sich hinter den FRBR? Welche Auswirkungen hat dieses Modell, das Beziehungen zwischen Entitäten darstellt, auf Regelwerke, Normdateien, Formate, Online-Kataloge und andere Bereiche? Welche Erfahrungen sind international bereits mit den FRBR gesammelt worden? Können wir die FRBR in Deutschland und Österreich nutzbringend in die Standardisierungsarbeit einbringen?

Abstract: The identification of works according to IFLA's report on Functional Requirements for Bibliographic Records offers challenges when applied to very large collections of bibliographic records. We describe an algorithm that identifies sets of works and discuss our experience applying the algorithm to OCLC's WorldCat. Four main types of works have been found in our analysis: augmented, revised, aggregate, and translated works. Each of these offers challenges for proper identification and collocation. Quite apart from algorithmic implementation, difficult conceptual problems were encountered in applying the FRBR model to aggregate works.

Abstract: The Library of Congress Subject Headings schema (LCSH) is by far the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains upward compatibility with LCSH, and any valid set of LC subject headings can be converted to FAST headings.

In: D-Lib magazine. 8(2002) no.9, x S.
Abstract: 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.

15O'Neill, E.T.: ¬The FRBRization of Humphry Clinker : a case study in the application of IFLA's Functional Requirements for Bibliographic Records (FRBR).
Abstract: The goal of OCLC's FRBR projects is to examine issues associated with the conversion of a set of bibliographic records to conform to FRBR requirements (a process referred to as "FRBRization"). The goals of this FRBR project were to: - examine issues associated with creating an entity-relationship model for (i.e., "FRBRizing") a non-trivial work - better understand the relationship between the bibliographic records and the bibliographic objects they represent - determine if the information available in the bibliographic record is sufficient to reliably identify the FRBR entities - to develop a data set that could be used to evaluate FRBRization algorithms. Using an exemplary work as a case study, lead scientist Ed O'Neill sought to: - better understand the relationship between bibliographic records and the bibliographic objects they represent - determine if the information available in the bibliographic records is sufficient to reliably identify FRBR entities.

16O'Neill, E.T.: FRBR: Functional requirements for bibliographic records application of the entity-relationship model to Humphry Clinker.
In: Library resources and technical services. 46(2002) no.4, S.150-159.
Abstract: The report from the IFLA (International Federation of Library Associations and Institutions) Study Group on the Functional Requirements for Bibliographic Records (FRBR) recommended a new approach to cataloging based on an entity-relationship model. This study examined a single work, The Expedition of Humphry Clinker, to determine benefits and drawbacks associated with creating such an entity-relationship model. Humphry Clinker was selected for several reasons - it has been previously studied, it is widely held, and it is a work of mid-level complexity. In addition to analyzing the bibliographic records, many books were examined to ensure the accuracy of the resulting FRBR model. While it was possible to identify works and manifestations, identifying expressions was problematic. Reliable identification of expressions frequently necessitated the examination of the books themselves. Enhanced manifestation records where the roles of editors, illustrators, translators, and other contributors are explicitly identified may be a viable alternative to expressions. For Humphry Clinker, the enhanced record approach avoids the problem of identifying expressions while providing similar functionality. With the enhanced manifestation record, the three remaining entity-relationship structures - works, manifestations, and items - the FRBR model provides a powerful means to improve bibliographic organization and navigation.

In: Journal of Internet cataloging. 4(2001) nos.1/2, S.35-47.
Abstract: This article describes FAST, the Faceted Application of Subject Terminology, a project at OCLC to make Library of Congress Subject Headings easier to use in Dublin Core metadata by breaking out facets of space, time, and form. Work on FAST can be watched at its web site, http://www.miskatonic.org/library/, which has recent presentations and reports. It is interesting to see facets and Dublin Core combined, though both LCSH and FAST subject headings are beyond what most people making a small faceted classification would want or need.
