Abstract: A method includes (a) obtaining a search word, (b) obtaining first to third concept maps including words and semantic distances between the words, (c) obtaining a first association map including degrees of association indicating how close the semantic distances included in the first and second concept maps are to each other; (d) obtaining a second association map including degrees of association indicating how close the semantic distances included in the first to third concept maps are to one another, (e) extracting, from the words as an associated word, at least one word whose difference between the degree of association with the search word included in the first association map and the degree of association with the search word included in the second association map is equal to or larger than a first threshold, and (f) outputting a result of a search based on the search word and the associated word.

Abstract: A method for expanding a word performed by a processor includes (a) obtaining a first word, (b) obtaining, from a memory, a concept map that is unique to a user and that includes a plurality of second words and semantic distances between the plurality of second words, the plurality of second words including words belonging to different categories, (c) determining, if the plurality of second words include a word corresponding to the first word, the word corresponding to the first word as a basic word, (d) selecting, on the basis of the semantic distances to the basic word, at least one of the plurality of second words included in the concept map as an adjacent word, and (e) outputting a result of a search on the basis of the first word and the adjacent word.

Abstract: A data generation apparatus includes a processor and a memory. The memory stores a generation rule including one or more time change values and/or one or more amplitude change values. The processor (a1) obtains a first biological data item including an event-related potential of a user and obtains a first label associated with the first biological data item, (a2) refers to the generation rule and generates one or more second biological data items by changing the first biological data item using the one or more time change values and/or the one or more amplitude change values, and (a3) outputs the one or more second biological data items associated with the first label, as training data related to the user.

Abstract: A learning system includes an output unit that outputs a first problem and a display message prompting a user to take a break, an acquisition unit that acquires an answer to the first problem from the user, an electroencephalogram measurement unit that measures an electroencephalogram of the user, and a control unit. The control unit determines whether first motivation is present on the basis of a first event-related potential included in the electroencephalogram and starting from a timing at which the first problem is output, determines whether second motivation of the user is present on the basis of a second event-related potential included in the electroencephalogram and starting from a timing at which the answer is acquired, and instructs the output unit to output a display message prompting the user to take a break if the first motivation is not present and the second motivations is not present.
