1. International Atomic Energy Agency October 2013INIS Training Seminar1 Subject Analysis: Computer Assisted Indexing 07 – 11 October 2013 Vienna, Austria Bekele Negeri INIS Unit Nuclear Information Specialist (Adapted from A. Nevyjel’s presentation)

2. International Atomic Energy Agency Subject Indexing Tools There are two main INIS products used for indexing: WinFibre and CAI WinFibre – for input preparation both bibliographic and subject indexing CAI (Computer Assisted Indexing) – for subject classification and indexing INIS/ETDE Thesaurus and INIS Subject Category Codes are incorporated in both.

7. International Atomic Energy Agency October 2013INIS Training Seminar7 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

15. International Atomic Energy Agency October 2013INIS Training Seminar15 CAI online for Member States introduced in July 2007 CAI Batch used by China Czech Republic (seldom) Georgia (only in 2012) Germany Iran Uzbekistan Vietnam CAI Online in use by Austria Bulgaria Cuba Israel (registering) Japan Mexico Netherlands (seldom) Uruguay CAI online and CAI batch are now regular services for Member States

16. International Atomic Energy Agency October 2013INIS Training Seminar16 CAI Batch and Online Processing Input: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

17. International Atomic Energy Agency October 2013INIS Training Seminar17 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

19. International Atomic Energy Agency October 2013INIS Training Seminar19 CAI Batch and Online Processing Reviewing Process Delete all suggested descriptors which are too general Add relevant descriptors which were not found numerical values, e.g. pressure ranges, temperature ranges,... 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

20. International Atomic Energy Agency October 2013INIS Training Seminar20 CAI Batch and Online Processing Finalisation Process CAI batch When reviewing of the record completed: Delete “##CAI suggestions## “ When reviewing of all records completed: Submit file to “INIS Input Box” CAI online When reaching the last record: press “export and exit” button File goes directly to INIS production system, or if required, sent back to Member State for reviewing
