Domain-specific lexically-driven pre-parser

A computer program product for domain-specific parsing, the computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform operations comprising:

• obtaining an input text at a text parser, the text parser includes a domain-specific lexically-driven pre-parser and a domain-independent rule-based parser;
• identifying a first term in the input text;
• accessing lexicon data to identify a first entry corresponding to the first term, the first entry including core data and non-core data, wherein the core data corresponds to domain-independent lexical information for the first term, and wherein the non-core data corresponds to domain-specific lexical information for the first term;
• determining, at the domain-specific lexically-driven pre-parser, that the non-core data of the first entry identifies a second term in the input text as a modifier of the first term;
• generating, at the domain-specific lexically-driven pre-parser, a partially parsed and bracketed version of the input text, wherein the partially parsed and bracketed version indicates that the second term modifies the first term in the input text;
• and
• generating, at the domain-independent rule-based parser, a parsed version of the input text based on the partially parsed and bracketed version of the input text.

A system comprising:

• a memory configured to store input text and lexicon data;
• a processor configured to:
• identify a first term in the input text;
• and
• access the lexicon data to identify a first entry corresponding to the first term, the first entry including core data and non-core data, wherein the core data corresponds to domain-independent lexical information for the first term, and wherein the non-core data corresponds to domain-specific lexical information for the first term;
• a domain-specific lexically-driven pre-parser configured to:
• determine that the non-core data of the first term identifies a second term in the input text as a modifier of the first term;
• and
• generate a partially parsed and bracketed version of the input text, wherein the partially parsed and bracketed version indicates that the second term modifies the first term in the input text;
• and
• a domain-independent rule-based parser configured to generate a parsed version of the input text based on the partially parsed and bracketed version of the input text.
