PROBLEM TO BE SOLVED: To prevent a sentence from being unclear by containing no omitted the subject or the object in a summary sentence when preparing the summary sentence of an electronic document. SOLUTION: In the case of preparing a summary sentence of a document, when a zero corresponding element zi such as omitted subject or object of a vocabulary element ti contained in the summary sentence to be prepared exists, it is discriminated whether this zero corresponding element zi is the element of a zero correspondence list ZAList or not (step S85) and in the case of YES, the vocabulary element ti is added to the summary sentence as it is (step S86) but in the case of NO, only when the zero corresponding element zi is not contained in the summary sentence, the zero corresponding element zi is put in parentheses and added to the summary sentence together with the vocabulary element ti (step S89). Then, ti and zi are added to ZAList. |
