1. An information processing apparatus comprising:
processing circuitry configured to implement
a keyword generator configured to identify object images from video based on both activity information on an activity history of a user and a first level of narrowing down and to generate candidate keywords, as candidates to be comments, by generating a candidate keyword for each of the identified object images;
an identifier configured to identify one or more target keywords to be comments from among the candidate keywords generated by the keyword generator based on both the activity information and a second level of narrowing down;
a comment generator configured to generate, for each of the one or more target keywords, a comment related to each target keyword; and
an adjuster configured to adjust both the first level of narrowing down and the second level of narrowing down in accordance with processing information on processing performable by the keyword generator and processing performable by the identifier.
