Abstract:

This paper presents a parser which is an extension of the deterministic model of natural language processing. The parser, named Grammar-Debugger, is made more powerful than the earlier models by a modified lookback mechanism and an additional error detecting and tolerating mechanism. The error detection and toleration capability is achieved by a minor modification of the grammar rules which are used to parse grammatical sentences, thus the generality of the grammar rules is preserved. The targeted application of the parser is in the field of CALL.
