PROBLEM TO BE SOLVED: To provide a syntax analysis system capable of suitably executing the analysis of modification even in a sentence having incomplete auxiliary post-positional word information. SOLUTION: A morpheme analysis processing means 2 divides a sentence to be analyzed into respective words and executes processing for collecting respective words to a clause and a cooccurrence relation data extracting means 4 extracts cooccurrence relation data from modification relation between respective clauses to be the morpheme analysis processing result of each sentence in document data stored in a corpus. A modification relation analyzing means 5 selects cooccurrence relation data having both of a clause having no particle in the processed result of the means 2 and a clause to be a modified candidate corresponding to the clause having no particle from the extraction result of the means 4 and recognizes a clause of cooccurrence relation data having the highest modification frequency out of the selected cooccurrence relation data as a modified clause, so that a more correct modified clause can be obtained. |
