  1. WorkshoponComputer-assisted Indexing Alexander Nevyjel 34th Consultative Meeting of INIS Liaison Officers 2-5 November 2008, Vienna, Austria 34th ILO Meeting

  2. Agenda • Review CAI procedures (workflow, formats, conventions) • Thesaurus extension: Hidden terms tables • Problems and how to overcome • Discussion and exchange of experiences • Hands-on training by INIS Subject Specialists(in their offices, open end for this afternoon)Tips, tricks, recommendations 34th ILO Meeting

  3. Objectives of Computer-assisted Indexing • Maintaining database quality • Saving of subject analysis manpower • Improving indexing consistency 34th ILO Meeting

  4. CAI-Workflow Batch Mode Interactive CAI Processing Conventional Processing 34th ILO Meeting

  5. CAI Batch and Online Processing • Input: MemSt-CC-yymmdd-xxxxxxxxxxx • Output: _MemSt-CC-yymmdd-xxxxxxxxxxx • MemSt is a standard prefix (meaning “member state”) • CC is the country code • yymmdd is the date when the file was generated • xxxxxxxxxxx is any additional identification • Examples • MemSt-AR-041203-thisismytestfile • MemSt-FR-041212-fileidentification 34th ILO Meeting

  6. CAI Batch Processing • Output: _MemSt-CC-yymmdd-xxxxxxxxxxx • These files will carry the CAI suggested descriptors in tag 800, preceded by the string ##CAI suggestions##; • Example: • 800^##CAI suggestions##; DESCRIPTOR1; DESCRIPTOR2; DESCRIPTOR3; ……. • sent back to the member state for reviewing 34th ILO Meeting

  7. CAI Online • File loaded to CAI online • All files of a Member State appear on the queue page as batch MemSt-XX • Please open only your own batch, do not touch other queues • Files in a queue will be opened one after the other, in the sequence as they have been loaded 34th ILO Meeting

  8. CAI Batch ProcessingReviewing Process • Delete all suggested descriptors which are too general • Add relevant descriptors which were not found • numerical values, e.g. pressure ranges, temperature ranges, etc • nuclear reactions • chemical compounds, alloys, etc. • CAI is cleaning up BT/NTs  clean up BT/NTs from manual additions • Clean up suggestions from homographic terms • Delete “##CAI suggestions## “ • Submit file to “INIS Input Box” 34th ILO Meeting

  9. CAI OnlineReviewing Process • Delete all suggested descriptors which are too general • Add relevant descriptors which were not found • numerical values, e.g. pressure ranges, temperature ranges, etc • nuclear reactions • chemical compounds, alloys, etc. • CAI is cleaning up BT/NTs  will give warnings for BT/NTs from manual additions • Clean up suggestions from homographic terms • Export file when finished • File will be exported to INIS Production System (or send back to MS for reviewing if requested) 34th ILO Meeting

  10. CAI Thesaurus extension “Hidden terms” are character patterns representing the different appearances of a concept in the free text, which is indexed by one or more descriptors. • handled similar to “forbidden terms” with one or more USE relations • CAI internal only • not exported to INIS production system • not exported to FIBRE • not printed in any appearance of the thesaurus • support identification of descriptors in the free text 34th ILO Meeting
