FRBR work-set algorithm by Thomas Butler Hickey( )

2 editions published between 2005 and 2009 in English and held by 47 WorldCat member libraries worldwide

"The research work-set algorithm generates an author/title key for each bibliographic record. These 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."--Page 2
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
NACO normalization : a detailed examination of the authority file comparison rules by Thomas Butler Hickey( )

1 edition published in 2006 in English and held by 1 WorldCat member library worldwide

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
Managing ambiguity in VIAF by Thomas Butler Hickey( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

The Virtual International Authority File (VIAF) is built from tens of millions of names represented in more than 130 million authority and bibliographic records expressed in multiple languages, scripts and formats. VIAF does not replace the source authority data, but creates something new built upon the relations mined from it. A common use of VIAF is in the creation of new 'local' authority records for authors based on information already in VIAF about the entity. VIAF can also be used as an authority file in its own right, for instance OCLC is now using VIAF as part of its identification of works and expressions. In a series of automated steps these names are linked and combined into VIAF clusters. Ambiguity occurs at several stages in VIAF, from the initial matching to cluster creation. VIAF's approach to managing this gives us a great deal of flexibility to deal with additions, deletions and changes to the underlying authority data. VIAF's approach to clustering has several rather novel aspects. The clustering itself proceeds in multiple stages in what could be called progressive refinement. It uses fairly loose matching to bring in candidates and then gradually brings them into the finished clusters using the information that can be gleaned from the rough groupings to make more informed decisions than could be made a priori. Another aspect is that all the information from all the records is used during the clustering. This results in a more fluid view of identity than hand-built authority files provide, while giving VIAF the ability to react to refinements in the clustering algorithms and new data on a regular basis. Finally, just the scale of VIAF provides opportunities the library community has not previously had to analyze and use authority data in machine processing. The problems and approaches used by VIAF may have implications in the use of linked data for other information services
Parallel text searching on a Beowulf cluster using SRW by Ralph R LeVan( )

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

This article describes our experience building a scalable, relatively inexpensive, and fast searching framework that demonstrated 172 searches per second on a database of 50 million records. The article should be of interest to anyone seeking an inexpensive, open source, text-searching framework that scales to extremely large databases. The technology described uses the SRW (Search/Retrieve Web) service in a manner nearly identical to federated searching in the metasearch community and should be of interest to anyone doing federated searching
