Overview Project overview Features Future development Demo Questions

Project Two types of records A bibliographic record represents a book, and is linked to multiple authority records. An authority record represents a single author or subject.

Goals Bibliographic Record Author field Name Date of Birth, Death Authority Record Authorized Form Alternate Forms: Alternate form 1 Alternate form 2 … See Also References to other authority records

Project Name matching Names are entered differently. Multiple pens names by the same person. Finding matching records Easy when authority record of an author already exists. A new authority record is created when an author does not exist. Importing different record formats

Technologies Used Java XML MySQL Hibernate Ant Marc4J

Supported Record Types MARC Authority records MARC Bibliography records Dublin Core records

Features A persistent data storage Import records Match records A functional API A prototype GUI

Importing Identifies the correct record formats Imports Marc and DublinCore XMLs Uses Marc4j to parse raw data to Marc XMLs Detects duplications Updates records with new information

Matching Phases

Matching Loops through all unmatched records. Tries various strategies and string transformations in order of confidence. If a match is found, a link is created with evidence. If no match is found, a new Authority record is created based on the Bibliographic record information

Name Transformations Names are transformed to get better matches. For example, Homer Simpson  Simpson, Homer Smith, Elizabeth ($q Ann Elizabeth)  Smith, Ann Elizabeth De la Mare, Walter  Mare, Walter De la Vanughan Williams, Ralph  Williams, Ralph Vanughan

Discriminators Adjusts the confidence in a match based on a discrimination criterion. For example, Common names Publication dates

Graphical User Interface Schedules jobs Filters and sorts results Views records and matches Manually matches of records
