Abstract: To support an infant's ability to understand and present moods. A mood information presentation tool (10) is a three-dimensional object that is an approximately regular hexahedron. Six faces of a surface of the three-dimensional object include at least a mood selection surface (100) and four mood degree selection surfaces (110, 120, 130, and 140). The mood selection surface (100) includes four mood regions. Each of the mood regions is made up of a mood face region displaying a picture simulating a face of different mood and a mood background region to which is given a predetermined basic color as a color corresponding to the mood. Each of the mood degree selection surfaces (110, 120, 130, and 140) is a surface which is in contact with one mood region of the mood selection surface (100), which is given the basic color given to the mood background region of the mood region, and which includes a set of a plurality of signs representing degrees of mutually different magnitudes.

Abstract: An index value assignment device comprises: a selection unit that prompts a user to select, from a sentence, one or more words that the user feels to have a same degree of a predetermined index value with respect to one or more first words for which the index value is known; a validation unit that validates the selection result by the user on a basis of the index value of a second word for which the index value is known from among the one or more words included in the selection result; and a determination unit that determines the index value with respect to a third word for which the index value is unknown from among the one or more words selected by the user, on a basis of the index value of the first word according to the selection result for which the selection result is determined to be valid. Consequently, the efficiency of assigning word familiarity is increased.

Abstract: To enable difficulty or a target period of a text to be estimated with high accuracy at desired granularity. A feature amount extracting unit 230 extracts a feature amount including an acquisition period of a word from a text of a picture book, and a difficulty estimating unit 232 estimates difficulty based on the feature amount extracted with respect to the text of the picture book and on a difficulty estimation model having been learned in advance.

Abstract: An apparatus uses a rank-by-rank set, extracted from a test word sequence having, as elements, a plurality of test words selected from a plurality of words ranked and a potential vocabulary sequence having, as elements, a plurality of potential vocabulary sizes, of the plurality of test words and the plurality of potential vocabulary sizes, and an answer regarding knowledge of the test words of a user to obtain a model representing a relationship between a value based on a probability that the user answers that the user knows the words and a value based on a vocabulary size of the user when the user answers that the user knows the words. Here, the plurality of test words are ranked to have order based on familiarity within subjects to the test words of the subjects belonging to a subject set. The plurality of potential vocabulary sizes correspond to the plurality of test words, are estimated based on familiarities predetermined for the words, and are ranked to have order based on the familiarities.
