Abstract: Identification means of an information processing system identifies, based on an action history of each of a plurality of users, a plurality of data items having a degree of action equal to or more than a predetermined degree. First information acquisition means acquires, based on the action history of each user, first information indicating relevance between the respective data items identified by the identification means. Output means outputs, when details of each of the plurality of data items are input, second information indicating relevance between the respective data items based on a predetermined parameter. Setting means sets the parameter based on the details of each data item identified by the identification means and the first information.

Abstract: A summary generating device includes at least one processor that is configured to use a plurality of different algorithms, which extract one or more elements from a document and obtain an appearance degree of each of the extracted elements, so as to obtain the elements and the respective appearance degrees of the elements from the document, normalize the obtained appearance degrees for each of the algorithms, select at least one sentence from the document based on the normalized appearance degrees, and generate a summary of the document based on the selected sentence.

Abstract: Searching means of a search system searches a database, in which a plurality of data items are stored, using character information entered by a user as a query. Providing means provides the user with a data item selected by the user from a search result obtained by the searching means. Training means trains a learning machine to learn a relationship between item information of the data item selected by the user and the character information used as the query. Obtaining means enters item information of a target data item into the learning machine and obtaining feature information of the target data item from the learning machine. Registering means registers the feature information in the database in association with the target data item.

Abstract: An information processing apparatus according to one of exemplary aspects of the present disclosure includes: an alternate pattern identifier 862 that identifies first instruction sequences in a program in a first language, each of the first instruction sequences leading to a result individually achieved by second instruction sequences in a second language different from the first language, the second instruction sequences including operators being common to the first instruction sequences; a pattern selector 865 that determines ratios for the operators of the second instruction sequences; and an instruction scheduler 870 that selects a second instruction sequence based on the ratios from the second instruction sequences for each of the first instruction sequences.
