Abstract:

The first step in preparing a sublanguage grammar to parse a given set of messages in a particular subdomain, namely Navy Casualty Reports CASREPs of the failure of Starting Air Compressors, was the porting of an English grammar from The Linguistic String project hereafter LSP at New York University. This grammar consists of 1 a set of BNF productions in the Syntactic Component 2 a series of LISTs in the LIST Component where generalizations are further codified, making the processing of sentences more efficient 3 a set of syntactic semantic Restrictions in the Restriction Component that constrains the productions of the grammar further 4 a set of syntactic transformations and regularizations in the Transformation Component that regularizes the various types of sentences parsed into similar structures and 5 a set of Formatting Rules in an Information Formatting Component that maps syntactic structures into information structures. In this report, we will be concerned only with the adaptations made to the syntactic or BNF Component, to the LIST Component, and to the Restriction Component.
