  1. 香港中文大學圖書館系統 University Library System The Chinese University of Hong Kong By Fanny Chan & Ernest Yik February 24, 2006 A Conceptual Model of Name Access Control for Institutional Repository

  2. Outline • Introduction • Traditional personal name authority control • Proposed conceptual model of name access control for IR • How to link to DSpace Repository & supports OAI-PMH integration • Limitations & suggestions

  3. Introduction • Why is name access control important for institutional repository? • Author search is common for IR. • Different name forms of authors resulted in incomplete retrieval. • Proper name access control enhances collocation.

  4. Existing author search is unsatisfactory.

  5. Traditional personal name authority control for IR • Unable to achieve complete retrieval: • Based on the real existence in bibliographic records. • Different name authority records may be created for the same author. • Require great effort to establish & maintain the name authority file.

  6. Established heading Not-used headings See-also references Bibliographic information

  9. The conceptual model of name access control for IR • Goal • Achieve complete retrieval by one stop author search. • Require the least effort to establish and maintain the name file. • Support cross-institutional search.

  10. Features of the conceptual model of name access control • Focus on personal name. • One record for one author. • No established names but the display names simply based on the official staff list, etc. • All name forms are equally valid and bear the author’s unique number for linking & matching.

  11. Features of the conceptual model of name access control (Cont’d) • Not rely on real existence in bibliographic records but focus on post-coordination. • Names are not stored in MARC records but decomposed into components & stored in separate name file.

  12. Sample name file Assuming user may search by any one of the following: Lau Lai Mei Grace Liu Liwei Chau Lau Lai Mei Grace Liu Li Wei Lau Lai Mei Zhou-Liu Liwei Lau L.M. Zhou-Liu Li Wei Lau Grace 劉麗薇 Grace Lau周劉麗薇 Grace Lau Lai Mei ……

  16. How the name file is linked to Dspace repository • The unique author ID in the name file serves as a matching key to map the names on DSpace repository. • Each name when input onto DSpace repository would be pre-assigned with the author ID. • This unique author ID could then link up all variant name forms of the same author on Dspace repository. • No matter which form is searched by, the publications of the same author would be collocated & retrieved.

  17. Search mechanism: from name file to DSpace Repository N System searches name file for matching names Any matches? User starts a new author search N Y System presents the list of matching authors with details to the user One or more names meet the need of the user? User checks the list of authors Y User selects the appropriate Names from the list System converts the names into unique author IDs System submits author IDs to DSpace for author search DSpace retrieves all publications which contain the specific author IDs

  18. Search mechanism: Sample search N Any matches? System searches name file for Grace Lau User searches by Grace Lau N Y Lau, Lai Mei Grace Lau, Lai Ming Grace Lau, Mei Mei Grace One or more names meet the need of the user? User checks the list of authors Y Lau, Lai Mei Grace Author ID F123 System searches author ID F123 on DSpace DSpace retrieves all publications which contain author ID F123

  19. How the NAC conceptual model supports OAI-PMH integration • In order to work with OAI-PMH harvesters that do not adapt the name access control model, we will need to add a “translation layer” to map author IDs back into their names.

  20. OAI-PMH integration Harvester DSpace-OAI “Translation layer” - Mapping author IDs to preferred author names Name files database DSpace Repository

  21. Limitations & suggestions • The response time is likely longer than the existing direct author search. • Author search is confined to CUHK authors. • However, the name file is extendable & allows cross-institutional search if other institutions are willing to adopt the similar name access control model & share the IRs & name files.

  22. Cross-institutional search
