Abstract: A non-transitory computer readable medium storing a program causing a computer to execute a process for information search, includes searching a document database for a basic document which is a document containing an input keyword; searching the document database for an associated document associated with the basic document; generating plural document sets by classifying a document group containing plural associated documents; and outputting, for each document set, a feature word which is a word characteristic to the document set.

Abstract: It is a non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process including: calculating a feature amount of each of document contents to which common attribute information is added; and generating distribution map information by plotting each of document contents in a feature amount space on the basis of the calculated feature amount.

Abstract: An information processing apparatus includes a selector and an extending unit. The selector selects a word in question training data corresponding to a topic. The extending unit extends the question training data by replacing the word selected by the selector in the question training data by a word in answer data corresponding to the topic.

Abstract: An object classification device includes a keyword determining unit, a keyword ordering unit and a classifying unit. The keyword determining unit determines keywords for one or plural objects. The keyword ordering unit orders the plural determined keywords based on a conceptual hierarchical structure which is a structure that hierarchically represents concept of words. The classifying unit classifies the objects so as to be associated with the ordered keywords.
