An information processing apparatus capable of improving accuracy of search results. The information processing apparatus includes: a management unit 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 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 that displays the object based on the calculated score.

Information processing apparatus, display method, and non-transitory computer-readable medium storing program

A search apparatus including: a search target extraction unit that references a data set use of a search criterion that includes attribute information, and extracts search target information that include the attribute information that match the attribute information of the search criterion; a score calculation unit that, in a case where the number of the extracted search target information pieces is not within a preset search result range, references a knowledge base and calculates a score for each of the attribute information pieces included in the extracted search target information pieces with use of a score function that has been determined in advance; a question generation unit that selects an attribute information piece based on the calculated scores, and generates question information use of the selected attribute information piece; and a search criterion generation unit that reflects an attribute information piece indicated by a response of the user to the question information in the search criterion, thereby generates a new search criterion.

Search apparatus, search method, and computer readable recording medium

An image search system () is provided with: a search key information acquisition unit () that acquires color specifying information indicating a plurality of colors and reference information indicating a reference of proportions of the plurality of colors being occupied in an image area; a specified color proportion information acquisition unit () that acquires specified color proportion information indicating proportions of the plurality of colors associated with the color specifying information, being occupied in an image to be processed; and an image search unit () that identifies whether the image to be processed is a search target image, based on the specified color proportion information and the reference information.

Image search system, image search method, and program

An information processing apparatus includes a search processing part and a result presentation part. The search processing part selects, based on a first feature(s) specified by a search condition(s) from a user and a second feature(s) not specified by the search condition(s) among a plurality of features extracted from a plurality of objects, a representative result object(s) that matches the search condition(s) from the plurality of objects. The result presentation part presents at least the representative result object(s) to the user.
