INIS/ETDE THESAURUS - definition
• Thesaurus"A thesaurus is a terminological control device used in translating from the
natural language of documents, indexers or users into a more constrained system language. It is a controlled and dynamic vocabulary of semantically and generically related terms which covers a specific domain of knowledge“
• INIS/ETDE ThesaurusThe INIS/ETDE Thesaurus contains the controlled terminology for indexing all
information within the subject scopes of the International Nuclear Information System (INIS) and the Energy Technology Data Exchange (ETDE). The terminology is intended for use in subject descriptions for input or retrieval of information in these systems.

STRUCTURE OF THE INIS/ETDE THESAURUS
• “Wordblock” The descriptor is placed in its correct semantic context
• Interrelationships: preferential (used for, seen for…), hierarchical (BT, NT…) and affinitive (RT)

SUBJECT INDEXING WITH THESAURUS
• Identify concepts – translate into valid descriptors
• Use the most specific descriptor – always prefer NTs
• Do not assign BT if its NT is assigned
• Use the word block – BT – for correctness; NT – for specificity; RT – for completeness
• Avoid overindexing (best between 5 and 20)
• Propose a new term when necessary - according to the rules

SUBJECT INDEXING: TOOLS
• There are two main INIS products used for indexing:
WinFibre and CAI• WinFibre – for input preparation: bibliographic description, subject
classification and indexing
• CAI (Computer Assisted Indexing) – for subject classification and indexing
• INIS/ETDE Thesaurus is incorporated in both products and regularly updated• In WinFibre – monthly
• In CAI – less frequently; Thesaurus Supplement

IAEA
COMPUTER ASSISTED INDEXING - CAI
• Automatic text analysis• Analyses the title and abstract
• Uses the Thesaurus
• Uses hidden terms – continuously expanded set of words and expressions
• Batch mode• Automatic run; review and deleting/adding descriptors
• On-line mode• Interactive assignment of category and descriptors
• INIS/ETDE Subject category scheme included
• INIS/ETDE Thesaurus included
