Parsing Ungrammatical Input: an Evaluation Procedure
Jennifer Foster · 2004
This paper presents a procedure for evaluating a parser's ability to produce an accurate parse for an ungrammatical sentence.It is based on the existence of a corpus of ungrammatical sentences, and a parallel corpus containing corrected, and hence grammatical, versions of the sentences in the first corpus.This procedure is applied to a wide-coverage probabilistic parser (Charniak, 2000), and the performance of this parser with respect to ungrammatical input is analysed.
