WorldCat Today

• Resources in nearly

all languages

• Contributed by more

than 20,000 libraries

worldwide

• More than half the

database is for works

not in English


WorldCat Today

• Bibliographic Records

• Hybrid records

• Parallel records

• Clustered at Work

level (FRBR)

Work Level Record

http://www.oclc.org/research/activities/workrecs.html


Create a landing

page summarizing

content for a work

Work Level Record: Objective


• The Content Cluster

• Enables better work record displays by reducing the number of lines that display for large works

• Enables a choice of format and presents the formats that could be acceptable substitutes

• Consolidates holdings for identical content

• The Manifestation Cluster is important

• Consolidates holdings at manifestation level

• In the short term allows the record catalogued in the language of the interface to be chosen for display

• Reduces apparent duplication

• Allows a more accurate count of the number of manifestations in WorldCat (as opposed to the number of records)

GLIMIR


Creates true multi-lingual displays • At work and manifestation levels

• Using all available data instead of “most appropriate record”

• Generates data

Corrects many of the 28 million records coded “und”

Better control and linking of translations

Input to refinement of work clusters

Smarter data storage

Multilingual Bibliographic Structure Project


• Worldcat.org selects the most appropriate record

to show to a user as representative of the work in

the short result list and beyond

• The end result will not be very satisfactory from a

multi-lingual viewpoint… here’s why

“Most appropriate” questioned


Which record is better to present to a German speaker?


Incomplete Swedish Record


Hybrid record


Most appropriate display


• Work level data, mined from all associated

bibliographic records will be displayed

supplemented with expression / manifestation

level data as the user drills through the short to

fuller versions of the metadata.

Multilingual Bibliographic Structure Project

End user interface will show works and manifestations not bibliographic

records; the cataloguing client will also show bibliographic records

Holding


• Language tagging of elements, particularly

• Summaries (M21 520)

• Subject headings

• Display in script preferred by the user if data is

available

• Improve translated interfaces

• Show consolidated holdings as appropriate

Important principles


Translations


• The cream of the world’s cultural and knowledge

heritage is shared by being translated

• WorldCat contains many rich cataloguing records

for these translations

Great works are translated

GOAL: Data mine the really good records to

improve clustering, presentation, authority

records and linked data


• Inconsistencies causing work clusters to be

incomplete & less than optimal search results

• Titles without subtitles

• Different forms of uniform title or missing uniform title

• Inverted title

• Different coding of original and translated information

Translations

Generated uniform title authority records will overcome most of these

differences without needing to edit individual records


• Improve FRBR work groups

• Made by data mining

• Contribute to VIAF

• Diffuse via VIAF as linked data

• Possibility to create web page / web service

Generate uniform title authority records


Translation records in VIAF

• Will enrich VIAF significantly

• New elements - translated title and translator

Author Title Expressions in VIAF Translation count in

WorldCat

Atwood Blind assassin 8 31

Guevara Notas de viaje 0 11

• Records are freely available to the world from

VIAF in

• MARC-21

• XML

• RDF (linked data)

• Just links in JSON

• And other formats as introduced

Diffusion of Translation records


• # of manifestations as

opposed to # of records

• # of works that have

translations

• Top translated authors

and works

• And more

We don’t know now, but soon will
