3 Introduction Subject Indexing  Analysing the information content  Expressing the information with terms of INIS Thesaurus  Understanding of the content  familiarity with INIS Thesaurus and indexing rules 3

4 Introduction Subject Indexing Tools  Fibre+ for input preparation (also classification and indexing)  C omputer A ssisted I ndexing (CAI) Only for classification and indexing  CAI online  CAI Batch mode 4

5 Member States usage CAI online  Argentina  Austria  Brazil  Bulgaria  Cuba  Israel  Japan  JINR  Mexico  Uruguay CAI Batch Mode  China  Georgia  Germany  USA  Uzbekistan  Vietnam 5

8 Preparation of batches for CAI online  Prepare bibliographic data with Fibre+  Leave first part of Tag 008 (subject category) empty  Leave Tag 800 (descriptor field) empty  Send your Batches to Kristina and Serene K.epperson@iaea.org and f.m.wong@iaea.orgK.epperson@iaea.orgf.m.wong@iaea.org  Batches will be loaded to CAI 8

16 CAI Batch Processing  Send Fibre+ file with empty tag 800  INIS will run the files through the CAI batch process  File will be sent back with CAI suggested descriptors in tag 800 for reviewing  Apply basic rules for indexing and delete ##CAI suggestions##  Submit file to “INIS Input Box” NIS.INIS-Input-Box@iaea.org 16

18 Basic rules for indexing in CAI  Carefully read title and abstract, scan full text  Choose relevant descriptors from suggested  NT instead of BT  3 to 20 descriptors (avoid over indexing)  Add descriptors which were not found  numerical values, e.g. pressure ranges, temperature ranges, etc.  nuclear reactions  chemical compounds, alloys, etc. 18

19 Special Attention  Energy, Pressure and Temperature Ranges  Translation of units  Case sensitivity  TiN  TIN (instead of TITANIUM NITRIDES)  …this can be …  CaN  CALCIUM NITRIDES  gas  GALLIUM SULFIDES  “…who is the …”  WHO (World Health Organization)  Verbs versus Nouns  “… this leads us to …”  LEAD  “… this leaves it ….”  LEAVES  Multi-meaning  … in isotopes…..  INDIUM ISOTOPES  …at 195 deg K…  ASTATINE 195 19

20 Special Attention  Homographic terms  Solutions  SOLUTIONS or MATHEMATICAL SOLUTIONS  Color  COLOR, COLOR CENTRES, COLOR MODEL  Flavor  FLAVOR, FLAVOR MODELS  Tunnel  TUNNELS, TUNNELING, TUNNEL EFFECT  Transport  Limited to the movement of goods and persons  Nuclear reactions: 14 N(γ,α) 10 B or γ + N 14 → α + B 10  PHOTONUCLEAR REACTIONS  NITROGEN 14 TARGET  ALPHA PARTICLES  BORON 10 20

21 Hidden Terms  Represent different appearances of a concept in the free text  Support identification of descriptors in the free text  CAI internal only  not exported to INIS production system  not exported to FIBRE  not printed in any appearance of the thesaurus 21
