1. A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising: acquiring question document contents and answer document contents, which are in a relationship of questions and answers; acquiring determination contents each indicating a different point of view of an answerer when answering the question; classifying the answer document contents in which a first one of the determination contents is set to a first set of the answer document contents and a second one of the determination contents different from the first one of the determination contents is set to a second set of the answer document contents; calculating a first feature amount of each of the first set of the answer document contents and a second feature amount of each of the second set of the answer document contents; calculating first distances between the first set of the answer document contents on the basis of the calculated first feature amounts; calculating second distances between the second set of the answer document contents on the basis of the calculated second feature amounts; classifying the first set of the answer document contents so that, in a case that there is the first distance equal to or greater than a value set in advance between a first subset of the first set of the answer document contents and a second subset of the first set of the answer document contents, first attribute information is added to the first subset of the first set of the answer document contents and second attribute information different from the first attribute information is added to the second subset of the first set of the answer document contents; classifying the second set of the answer document contents so that, in a case that there is the second distance equal to or greater than the value set in advance between a first subset of the second set of the answer document contents and a second subset of the second set of the answer document contents, third attribute information is added to the first subset of the second set of the answer document contents and fourth attribute information different from the third attribute information is added to the second subset of the second set of the answer document contents; comparing the first distance and the second distance; in a case that the first distance is greater than the second distance, determining that the first determination contents is a remarkable point for generating the answer from the question on the basis of classifying results of the classifying; and in a case that the second distance is greater than the first distance, determining that the second determination contents is the remarkable point for generating the answer from the question on the basis of the classifying results of the classifying.
