Abstract:

A natural language understanding system is described that is designed to work with variable grammars. This is distinct from most natural language systems which can make automatic lexical changes in the dictionary, but can alter the grammar only by actual programming changes. This parsing scheme was developed as part of a larger system that could detect limitations to its grammar and automatically update the grammar, thereby improving its performance. Thus, the need to parse with a variable grammar. The key issue is not the ability to syntactically parse with different grammars, but the ability to mesh semantics with the parses defined by grammars of varying complexity.
