Abstract
A search request is syntactically analyzed, and location constraint data for keywords and function words (FNWORD) are extracted that constitute partial-order relationships. A document, which is to be retrieved and for which no syntactic analysis is required, is searched for that contains a sentence that matches the partial-order relationship. In the search for the document containing the sentence that matches the partial-order relationship, a sentence having a short context that matches the partial-order relationship is regarded as a sentence that has a higher similarity.
