  2. CatWork

  3. Background • History of CJK records • Retrospective Conversion • Reclassification • Backlog Reduction

  4. History of CJK records • App. 168,000 records using Pinyin with hyphenation have been converted into standard Pinyin • App. 70,000 records from RLIN have been converted from Wade-Gile into Pinyin except Tag 1XX,6XX,7XX • 79,015 old records’ Single Pinyin Syllable were generated by a program in 1996 but not reaching the current Pinyin standard • Fung Ping Shan Library Classification

  5. Retrospective Conversion • Automatic Conversion again? • High Quality Records need human involved • Change the major direction from automatic conversion to automatic matching and retrieving • Automatic conversion become an assistant only

  6. Reclassification • From Fung Ping Shan Library Classification to LCC

  7. Backlog Reduction • From brief records to complete cataloged bibliographical records

  8. How can automation help? • Use Resources from JULAC members (Academic Libraries in HK) • Reasons: • Overlapped collection (especially CJK) • Similar cataloguing standard/requirement • Use the same library system (Innopac)

  9. What is CatWork? • A byproduct of the recon & re-class projects • A Web version of InnoFace (see HKIUG 2001) • Not a machine of automatic cataloguing • A cost-effective tool for reducing redundant cataloguing work among libraries • TwinsPAC • A new design of a user-friendly and two-in-one interface for cataloguers to compare two bibliographic records from two WebOPACs

  10. TwinsPAC

  11. What is CatWork? (Cont,d) • An all-in-one program includes features: • XML, UTF-8 & WebOPAC based • Cataloguers input Bib record number only for matching • Extract the Bib record and backup the MARC record from the source library • Convert the Bib record into XML format • Match the Bib record to other libraries’ records • Download the MARC record in ISO-2709 exchange format from the target library • Add Tag 907 with the source record’s bib no. to the target MARC record • Overlay the MARC record of the source library with the target MARC record • Options: Instant Matching and Batch Matching

  14. Practical Experiences with CatWork • Step 1: 79,015 HKU CJK Bib records were extracted and converted into XML format for matching • Step 2: 28,275 CU Bib records were found • Step 3: 28,275 CU MARC records were downloaded • Step 4: 28,275 HKU MARC records were overlaid by CU MARC records • Time: The program’s running time of the above steps was within 48 hours • Hit rate: 36% • Accuracy: 99.9% (Cataloguer found ONE mismatched record within 1,000 records) • Saved Cost: If a staff takes 10 min. to do recon and re-class for one record and the salary is HK$45 per hour, then these 28,275 records could save HK$212,062.50

  15. How to balance the Matching Rules? Accuracy Hit Rate Rules Tight Loose

  16. Major Matching Rules • Search Title and Publication Year [http://catalog.lib.washington.edu:1087/search/t{215f6f}{213b65}/t{215f6f}{213b65}/,,,B/frameset&FF=t{215f6f}{213b65};Ya=1989;Yb=2001&,,] • Target Record has been catalogued [Includes LC call no. in local tags: 09X] • Target Record’s Tag 260 contains Source Record’s Publication Place and Publisher [Use Inclusive matching instead of Exactly Matching]

  17. Matching Flows for Each Field Source = Tag 880 Target = Tag 880 Yes Yes Source has Tag 880 Target has Tag 880 TC  SC Compare SC  TC No No Source = Main Tag Target = Main Tag

  18. Current Status in using CatWork • CUHK: Completely OK • HKUST: Completely OK • POLYU: UTF-8 port of WebOPAC has not been released • CITYU: Matching is OK but the MARC exported from its WebOPAC cannot be uploaded • LU: UTF-8 port of WebOPAC has not been released • HKIED: UTF-8 port of WebOPAC has not been released • UWASH: Completely OK • HKU: Completely OK

  19. Future or Trend • 獨樂樂不如與眾同樂 - 歐陽修 (Singing together is happier than singing alone) • Resources Sharing • Co-operation

  20. 獨樂樂不如與眾同樂 A JULAC member can be selected as the source Library

  21. Next Version • Backup & Download: using XML format from Innopac’s xrecord function instead of ISO-2709 format • Simplified the program’s procedures • Faster • More Linkages • E.g. ISBN or Author for reference • Add User-defined matching rules: Flexible, Simple and User-friendly • Add a Bib record Pre-Editor on the Web for cataloguers to edit before uploading the MARC

  22. Thank you for all cataloguers’ effort If there is no cataloguer, the matching result will be “0”. LO Tin King 2003.12.09
