Abstract
In a syntactic analysis apparatus, when a syntax analyzing section fails in a syntactic analysis of an input sentence due to a syntactic error included in the input sentence and thus is unable to generate a syntactic tree of the input sentence, an error analyzing section receives syntactic subtrees of the input sentence obtained by the syntax analyzing section up to such failure and applies a given error analyzing rule to the received syntactic subtrees so as to identify the included syntactic error. The input sentence is corrected based on the identification of the syntactic error so as to be sent to the syntax analyzing section. The syntax analyzing section performs the syntactic analysis of the corrected input sentence and generates a syntactic tree of the corrected input sentence.
