Abstract: An information processing device includes: a processor configured to: select pairs of tokens; when the selected pairs of tokens are presented to a user, receive an evaluation, made by the user, of degrees of relevance between the presented pairs of tokens; calculate degrees of relevance between the presented pairs of tokens based on the received evaluation; re-select pairs of tokens having comparative calculated degrees of relevance; when the re-selected pairs of tokens are presented to the user, re-receive an evaluation, made by the user, of degrees of relevance between the presented pairs of tokens; and re-calculate degrees of relevance between the presented pair of tokens based on the re-received evaluation.

Abstract: An information processing apparatus includes a processor configured to: receive a query; and, when the received query includes a predetermined underlearned word, receive, as information for learning the underlearned word, annotation information for the underlearned word.

Abstract: A document data processing apparatus includes a memory and a processor. The memory stores a distributed-representation set including multiple distributed representations corresponding to multiple pieces of data. The processor is configured to modify the distributed-representation set on the basis of multiple data pairs and multiple scores corresponding to the data pairs. The data pairs are subjected to learning. The processor is configured to modify the distributed-representation set in such a manner that, for each of the data pairs, a value indicating a relationship in a modified distributed-representation pair corresponding to the data pair comes close to a score corresponding to the data pair.

Abstract: A search apparatus includes a first control unit that, in a case of displaying a search result of content information searched with a selected search word, performs control such that recommended words corresponding to the search word are displayed; a second control unit that, in a case of displaying a search result of content information searched by adding a selected recommended word, which is selected from the recommended words, as a search word, performs control such that the selected recommended word is displayed in a search word display region at which the search words are displayed, and the recommended words corresponding to the selected search word and the added search word are displayed; a reception unit that receives a stored search word, out of the selected search word and the added search word, the stored search word being displayed in a storage state indicating that the stored search word is not used for search of the content information but is capable of being reselected; and a third control unit

Abstract: A search apparatus includes a receiver and a determining unit. The receiver receives a search term for a search. The determining unit determines suggested terms to be used for refined searches, the refined searches each using the search term and a respective one of the suggested terms. The suggested terms are determined based on (i) an amount of overlap between results of the refined searches and/or (ii) an amount of difference between the number of results of one of the refined searches and the number of results of another one of the refined searches.
