Subject Indexing ToolsSubject 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.

“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

CAI Batch and Online ProcessingCAI 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


CAI Batch ProcessingCAI 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


CAI Batch and Online ProcessingCAI Batch and Online ProcessingReviewing ProcessReviewing 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
