Abstract
Although thesauri can be solve some problems posed by computerised data base searching (synonyms, generic representation) their compilation requires extensive time and effort of experts and their maintenance is also difficult. Describes how a thesaurus was compiled and maintained automatically by taking advantage of the specially designed formats to input expertise with ease. The thesaurus was named a dynamic thesaurus because it depends on the set of stored data and is adapted to the necessary and sufficient range of keywords. A data base of polymers is taken as an example.
