Project partners

• National Library of Luxembourg• Manages ALEPH & PRIMO for the network of

libraries in Luxembourg

• Centre national de littérature• Manages the content of Autorenlexikon

• Magic moving pixel• IT management side for Autorenlexikon

The pilot project

• November 2012 – January 2013

• Goal:• Analyze the possibility to create links between the

authors in ALEPH (bibliographic / authority records) and their corresponding authors in Autorenlexikon.

• The analysis determined the best technological choices and the needed manpower.

The pilot project

• Questions to be answered:• How to create a link between authors (string

matching / id’s)?• How to deal with identical names?• How to deal with the authority records?• How to do find (and save?) the matches?

– “on the fly” with the help of web services– “offline” (storing the matches in a DB)

The pilot project

• Results:• Low number of matches between Autorenlexikon

» and the bibliographic database (~ 60%)» and the authority database (~ 35%)

• No ID matching possible => string matching• Prototype for display in the ALEPH catalogue

The pilot project• OPAC prototype

The linking project

• Timeline: March 2013 – present (in progress)

• Phase 1: March – May 2013 • Adjust matching algorithm• Create database with matches• Create web service to be used for the display in the

catalogue and in Autorenlexikon• Display matches in the ALEPH OPAC• Create validation service

The linking project

• Adjust the matching algorithm• Normalization rules• Cataloguing rules: ALEPH (MARC21) vs

Autorenlexikon• Levels of matching (accuracy)

• Create database with matches• Update database automatically and regularly, using

as input exports from ALEPH (bibliographic database), respectively Autorenlexikon
