Abstrakt: The construction of computer software to translate from IUPAC systematic organic chemical nomenclature into concise connection tables (CCTs) is described. A parser to perform the syntax analysis phase was produced by application of a modified SLR parser generator to the context-free grammar developed in the second paper of this series. Semantic processing of names accepted by the parser involves a second pass through the name by the established path. Semantic information associated with the morphemes, in the form of CCT fragments, is extracted from the dictionary and used to build the CCT. Data structures are described that are used to check the chemical validity of the CCT, and hence the name, and to ensure alphabetic ordering of substituent prefixes. [ABSTRACT FROM AUTHOR]
