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: Provided is an invention for efficiently searching for books used in training to reduce metathesis. A book search database storage unit 110 stores a book search database in which information identifying a book, information regarding a frequency of a proximity number for a mora character notation pair appearing in forward order in the book, and information regarding a frequency of a proximity number for the mora character notation pair appearing in reverse order are associated with each other. A display unit 300 displays a book search screen including a correctly pronounced phrase input region and an incorrectly pronounced phrase input region. A subject pronunciation designation unit 120 determines two mora character notations and a proximity number to use as search conditions based on an input of the correctly pronounced phrase input region and an input of the incorrectly pronounced phrase input region.

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.

Abstract: An apparatus selects a plurality of test words from a plurality of words, presents the test words to users, receives answers regarding knowledge of the test words of the users, and obtains a model representing a relationship between values based on probabilities that the users answer that the users know the words and values based on vocabulary sizes of the users when the users answer that the users know the words, by using the test words, estimated vocabulary sizes of people who know the test words, and the answers regarding the knowledge of the test words. Here, the estimated vocabulary sizes are obtained based on frequencies of appearance of the words in a corpus and parts of speech of the words.

Abstract: A vocabulary size estimation apparatus includes a question generation unit configured to select a plurality of test words from a plurality of words, a presentation unit configured to present the test words to users, an answer reception unit configured to receive answers regarding knowledge of the test words of the users, and a vocabulary size estimation unit configured to obtain a model representing a relationship between values based on probabilities that the users answer that the users know the words and values based on vocabulary sizes of the users when the users answer that the users know the words, by using the test words, estimated vocabulary sizes of people who know the test words, and the answers regarding the knowledge of the test words. The question generation unit selects, among the plurality of words, words whose degrees of adequacy of notations meet a predetermined criterion as the test words.

Abstract: The vocabulary size estimation apparatus selects a plurality of test words from a plurality of words, presents the test words to users, receives answers regarding knowledge of the test words of the users, and obtains a model representing a relationship between values based on probabilities that the users answer that the users know the words and values based on vocabulary sizes of the users when the users answer that the users know the words, by using the test words, estimated vocabulary sizes of people who know the test words, and the answers regarding the knowledge of the test words. Here, the vocabulary size estimation apparatus selects the test words from words other than words characteristic of a text in a specific field.

Abstract: Provided is a technique for effectively searching for a book for an articulation disordered-child to use in practice. A search condition setting unit 120 sets a search condition for a speech sound in accordance with a selection state of kana symbol buttons disposed in a book search screen, the kana symbol buttons corresponding one-to-one to kana symbols indicating respective speech sounds. A search unit 130 searches for a book in which a desired speech sound appears, in accordance with the search condition. A book search screen includes at least one of a Japanese syllabary button group in which the kana symbol buttons are classified as vowels or consonants, and an articulation button group in which the kana symbol buttons are classified by articulatory organ and articulation manner.
