Abstract: The present disclosure is to provide an information processing apparatus capable of improving accuracy of search results. The information processing apparatus (10) according to the present disclosure includes: a management unit (11) that manages at least one object, an attribute by which the object is classified, and a certainty factor indicating a probability that the object has the attribute in association with each other; a calculation unit (12) that, using a certainty factor of an attribute designated as a search condition and a certainty factor being managed in association with an attribute identical or similar to the attribute designated as the search condition, calculates a score indicating a matching degree of the object with the search condition; and a display unit (13) that displays the object based on the calculated score.

Abstract: An information processing apparatus (1) includes: a presence information acquisition unit (2) that acquires presence information that is generated based on images shot for each of a plurality of predetermined places and indicates a place where a person is present at a point in time of the shooting of the images; and a presence place estimation unit (3) that estimates a place where a specific person is currently present from among the plurality of predetermined places based on the acquired presence information. The presence information includes time information at the point in time of the shooting. The presence place estimation unit (3) estimates the place where the specific person is currently present using a presence probability of the specific person at the predetermined places, the presence probability being calculated based on an amount of time elapsed from the point in time of the shooting.
