1. International Atomic Energy Agency November 2009INIS Training Seminar1 INIS Training Seminar Subject Analysis, Thesaurus und Computer Assisted Indexing 23 – 27 November 2009 Vienna, Austria Alexander Nevyjel Head, Content Management Group

2. International Atomic Energy Agency November 2009INIS Training Seminar2 Introduction to Subject Analysis Subject Analysis should be carried out whenever possible by subject specialists with a good knowledge of the subject matter and a familiarity with the subject analysis tools of the respective database (subject categories, thesaurus, subject analysis rules) Steps of Subject Analysis subject classification abstracting subject indexing

3. International Atomic Energy Agency November 2009INIS Training Seminar3 Subject Classification The main topic of the document determines the primary subject category If there are other significant topics, one or more secondary subject categories can be assigned in addition

4. International Atomic Energy Agency November 2009INIS Training Seminar4 Abstracting Each input item should contain an English abstract (exception: short communications) Abstracts in other languages are optional If an author abstract is available, it should be checked by the subject specialist, and edited, if necessary An abstract should be as informative as possible Emphasize what is novel about the information in the original document

5. International Atomic Energy Agency November 2009INIS Training Seminar5 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“ This definition has been adopted by UNESCO „Guidelines for the establishment and development of monolingual thesauri“, UNESCO, SC/W/255, Paris, September 1973

7. International Atomic Energy Agency November 2009INIS Training Seminar7 Subject Indexing Subject indexing means analysing the information content of a piece of literature and expressing the meaningfull information content in the language of the database using the controlled vocabulary of the Thesaurus Understanding of the content --> subject specialist Familiarity with Thesaurus and indexing rules Select a set of descriptors that describes the subject content of the piece of literature

8. International Atomic Energy Agency November 2009INIS Training Seminar8 Procedures for Indexing Carefully read the title and abstract and scan the body of the piece of literature scan the full text ( introduction, table of content, tables, graphs, figures, conclusion) to find information items missing from the abstract or requiring more precision Identify the concept(s) about which the piece of literature contains useful information Translate the concepts into descriptors Avoid overindexing

9. International Atomic Energy Agency November 2009INIS Training Seminar9 Proposed Terms (Technical Note 175) If no suitable descriptor exists in the Thesaurus for the retrieval of a usefull concept, make a proposal for a new one, containing the following: Proposed term Proposed word block of the term (in particular proposed BTs) Potential forbidden terms pointing to this proposed descriptor Scope note when appropriate Explanation and justification for the proposal One or more sample records

10. International Atomic Energy Agency November 2009INIS Training Seminar10 The purpose of subject indexing is to enable useful retrieval

12. International Atomic Energy Agency November 2009INIS Training Seminar12 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
