An interactive control system according to an embodiment includes one or more hardware processors configured to function as a detection unit, a conversion unit, first and second estimation units, and an attribute determination unit. The detection unit detects an input keyword from input information. The conversion unit converts the input information into information including the input keyword and the input-keyword-excluded context information. The first estimation unit estimates, from the context information, at least a first estimate information piece in which the input keyword's first attribute is associated with a first likelihood of the first attribute. The second estimation unit estimates, from the input keyword, at least a second estimate information piece in which the input keyword's second attribute is associated with a second likelihood of the second attribute. The attribute determination unit determines the input keyword's attribute based on the first and second estimate information.

According to one embodiment, the interface-providing apparatus comprises an identifying unit and a generating unit. The identifying unit identifies a keyword from dialogue data including a question text to request information, and a response text in reply thereto. The generating unit generates display information to display a user interface for receiving feedback input relating to a degree of usefulness of a keyword when searching for the requested information.

Interface-providing apparatus and interface-providing method

According to one embodiment, the data generation apparatus includes a speech synthesis unit, a speech recognition unit, a matching processing unit, and a dataset generation unit. The speech synthesis unit generates speech data from an original text. The speech recognition unit generates a recognition text by speech recognition from the speech data. The matching processing unit performs matching between the original text and the recognition text. The dataset generation unit generates a dataset in such a manner where the speech data, from which the recognition text satisfying a certain condition for a matching degree relative to the original text is generated, is associated with the original text, based on a matching result.

According to one embodiment, a dialogue apparatus includes a processing circuit. The processing circuit designates one database from among a plurality of databases. The processing circuit extracts a keyword from text information. The processing circuit searches the designated database and another database which is included in the plurality of databases and which is other than the designated database, by using the keyword. The processing circuit generates a response in accordance with a first number of hit items, which is a number of data items matching the keyword in the designated database, and a second number of hit items, which is a number of data items matching the keyword in said another database.

According to one embodiment, an information processing apparatus includes a processing circuit. The processing circuit generates each of keywords stored in a frequently asked question (FAQ) collection as an utterance sentence. The processing circuit generates dialogue data for each of the keywords, the dialogue data generated by performing a dialogue for each of the keywords at least once, the dialogue obtained by generating a response sentence to the utterance sentence based on a result of searching the FAQ collection by use of the utterance sentence. The processing circuit generates aggregation data representing how often each of the keywords is used in the dialogue, based on the dialogue data.

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 dialog system includes a processor. When a first sentence including one or more words is input by a user, the processor sets at least a part of the one or more words as a first query keyword. The processor selects, from a question-answer table including question-answer pairs, one or more of the question-answer pairs including the first query keyword. Each question-answer pair includes a question and an answer to the question. When a number of the selected question-answer pairs is 1, the processor outputs a first response indicating the answer. When the number is not less than a first threshold, the processor outputs a second response including first and second question keywords. The first question keyword is extracted from question keywords included in one of the pairs. The second question keyword is extracted from other question keywords included in another one of the pairs.
