Metadata quality and FRBRization of MARC

What metadata quality issues are of concern in the migration of metadata to new models (e.g. FRBR)

How do computational techniques compare to expert cataloger FRBR application?

Page 6: Current Research on and Use of FRBR in Libraries

Group 1 Entities

Work: a distinct intellectual or artistic creation ; abstract.

Expression: the intellectual or artistic realization of a work ; abstract.

Manifestation: the physical embodiment of an expression of a work.

Item: a single exemplar of a manifestation.

Page 7: Current Research on and Use of FRBR in Libraries

Group 1 Entities Hierarchy

A work is realized through an expression, which in turn is embodied in a manifestation, which is exemplified by an item.

FRBR

In 1998, Functional Requirements for Bibliographic Records: Final Report was published by IFLA (International Federation of Library Associations and Institutions)

New conceptual model to represent the “bibliographic universe”. Based on an entity-relationship model.

User tasks are identified (i.e. find, identify, select, and obtain)

Comprised of 10 entities, Arranged into 3 groups.

Page 9: Current Research on and Use of FRBR in Libraries

Research methodology

Use a selected author’s MARC records (Mark Twain)

Have expert cataloger assess work-set relationships

Compare expert assessment with computational FRBR algorithms

Expert cataloger assessment

Expert cataloger review410 records – 147 total work-sets with 2 or more expressions420 work-sets with only one expression

Largest work-setsThe Adventures of Huckleberry Finn (26 records)The Adventures of Tom Sawyer (14 records)

Metadata most helpful in grouping work-setsTitleAuthorCombination of both title and author

Metadata quality assessment

Main quality issue: Lack of description for complex relationships

Model application is expensive in both computer and expert efforts

New data models (LoD) are changing our view of MARC metadata
