Definition of thesaurus • A semantic network of unique concepts
• Thesauri may be monolingual or multilingual
• Thesauri may have the following three relationships:
• Equivalence Relationships
• Hierarchical Relationships
• Associative Relationships
Why still the need for Controlled vocabs?
1. Synonyms • ‘salinity’ and ‘saltiness’
• ‘VHS’ and ‘Very High Frequency’
2. Homonyms Mercury (planet)
Mercury (metal)
Mercury (automobile)
Mercury (mythical being)
The purpose is fiveways 1. For translation 2. For consistency 3. For indication of relationships 4. For labeling and browsing 5. For information retrieval
Developed since 1980
36.000 concepts, and 255.000 terms

No names of persons and unique events
‘Cathedal’ yes, but not ‘Chartres cathedral’ (CONA)

Structure of the AAT
AAT is organized for general use
FAQ: why aren't terms organised like I expect them to be. Why aren’t communion cups and chalices narrower terms to church plate?
Communion cups
BT: drinking vessels BT: liturgical vessels
The AAT's organization stresses function and form over the context in which an object is used
The AAT links concepts to an alternate parent using polyhierarchical relationships
Thesaurus relations The Hierarchical Relationship broader- en narrower terms
