A document analyzing method comprising: determining whether a ground for the assertion with respect to a proposition is the same or not based on whether citation source documents in the form of an electronic document cited in electronic documents are common or not; and combining, based on the determination result, electronic documents including an assertion with respect to a given proposition, between which the assertion standpoint on whether to affirm or deny the proposition or whether to be in a neutral standpoint with respect to the proposition and a ground for the assertion standpoint are the same, into one group.
