A sentence search apparatus includes a processing circuit. The processing circuit: accept a character string input by a user; search a sentence collection in which a plurality of sentences as a search target is accumulated based on the accepted character string to acquire one or more search result sentences matching the accepted character string; perform sentence analysis on the search result sentence to acquire a dependency relation between words constituting the search result sentence; and determine one or more recommended words for narrowing down the search result sentence to a sentence desired by the user based on the accepted character string, the search result sentence, and the dependency relation.

Sentence search apparatus, sentence search method, and storage medium

An information processing device includes at least one hardware processor. The hardware processor selects one or more pieces of partial document data from document data. The hardware processor extracts, from the partial document data, first information being a word or a phrase for specifying a first attribute of the partial document data. The hardware processor extracts, from the partial document data, second information being a word or a phrase for specifying a second attribute of the partial document data. The hardware processor calculates a first feature value representing a feature of the first information. The hardware processor calculates a second feature value representing a feature of the second information. The hardware processor analyzes the document data on the basis of the first feature value and the second feature value.

According to an embodiment, a dialogue data collection system includes a presenter, a determiner, a notifier and a collector. The presenter receives response information that the dialogue management apparatus generates by advancing a dialogue status based on the spoken phrases, and presents the response information to the worker. The determiner compares the response information to one or more achievement conditions predetermined relative to the task, and determines achievement or non-achievement of the task based on whether or not the achievement conditions are satisfied. The notifier notifies the worker of achievement of the task. The collector collects dialogue data including the spoken phrase and the response information.

Dialogue data collection system and dialogue data collection supporting apparatus

According to one embodiment, a classification apparatus includes the following elements. The target log extraction unit extracts a set of dialogue logs for a dialogue from dialogue logs for dialogues between a user and an interactive system, the dialogue including a first speech and a second speech of the user, the set of dialogue logs including information indicative of a classification used for a search performed by the interactive system based on the first speech, information indicative of a failure in the first search, and data acquired as a result of a search performed by the interactive system based on the second speech. The classification relation generator generates a classification relation in which the classification is associated with the data.

Classification apparatus and classification method

According to one embodiment, a speech translation apparatus includes a speech recognition unit, a translation unit, a search unit and a selection unit. The speech recognition unit successively performs speech recognition to obtain a first language word string. The translation unit translates the first language word string into a second language word string. The search unit search for at least one similar example and acquires the similar example and a translation example. The selection unit selects, in accordance with a user instruction, at least one of the first language word string associated with the similar example and the second language word string associated with the translation example, as a selected word string.

Speech translation apparatus, method and program

A variable voice rate apparatus to control a reproduction rate of voice, includes a voice data generation unit configured to generate voice data from the voice, a text data generation unit configured to generate text data indicating a content of the voice data, a division information generation unit configured to generate division information used for dividing the text data into a plurality of linguistic units each of which is characterized by a linguistic form, a reproduction information generation unit configured to generate reproduction information set for each of the linguistic units, and a voice reproduction controller which controls reproduction of each of the linguistic units, based on the reproduction information and the division information.

Variable voice rate apparatus and variable voice rate method

An annotation input section reads from a text file the individual data items constituting an annotation pasted in a specified annotation position on a text as a result of the annotation being inputted from an annotation input window and acquires the input positions of the annotation data items and information on their size. A annotation image magnification change section produces a reduced or enlarged image of the display image of the annotation on the basis of the input positions of the individual annotation data items in the annotation and information on their size acquired by the annotation input section and a specified magnification indicated by a magnification storage section. A text and annotation image display section produces a display image by putting the reduced or enlarged display image of the annotation in the user-specified annotation position on a text display image and displays the display image on the text display screen of a display unit.
