http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=7284 Bug #: 7284 Summary: Authority matching algorithm improvements Classification: Unclassified Change sponsored?: Seeking cosponsors Product: Koha Version: master Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P5 - low Component: MARC Authority data support AssignedTo: jcamins@cpbibliography.com ReportedBy: jcamins@cpbibliography.com QAContact: ian.walls@bywatersolutions.com At present, the automatic authority matching for MARC21 is of limited use because it fails on headings with more than one subfield, doesn't take into account subfield codes, and considers punctuation significant. An improved matching algorithm should be able to match the following headings to the correct authorities (these particular examples are from a local authority file): =650 #4$aHistory =650 #4$aHistory =650 #4$aHistory$xBibliography (the technique of bibliography as applied to the study of history) =650 #4$aHistory$vBibliography (bibliographies about history) =650 #4$aHistory$vBibliography. =650 #4$aHistory$zGreek Empire$vBibliography =650 #4$aHistory$zGreek Empire$vBibliography. =650 #0$aHistory. =650 #7$aHistory.$2abc Those headings should match the following authorities: =150 #4$aHistory. =150 #4$aHistory$xBibliography. =150 #4$aHistory$vBibliography. =150 #4$aHistory$zGreek Empire$vBibliography. =150 #0$aHistory. =150 #7$aHistory.$2abc Libraries with examples of problematic headings from other authority files are respectfully requested to provide them in comments for the purpose of testing. There are a number of additional changes needed to make the link_bibs_to_authorities.pl script and the situation where BiblioAddsAuthorities=allow work properly: * The option to link headings to the first matching authority, even if there is more than one (and provide some sort of warning about that fact) * Verbose mode on link_bibs_to_authorities.pl should offer more information. * link_bibs_to_authorities.pl should be able to process only a portion of the catalog. * Allow machine-created authority records to be used for indexing. Potential future changes that would make these features even more useful: * A web interface to link_bibs_to_authorities.pl * An authority record de-duplicator * An option to correct punctuation when authorizing headings (either via link_bibs_to_authorities.pl or in the cataloging module) -- Configure bugmail: http://bugs.koha-community.org/bugzilla3/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
