Abstract: An expanded utterance that is used to output a more appropriate output utterance for an utterance can be generated. An utterance sentence expansion device includes an expansion unit that inserts, for an utterance that is an utterance to be expanded that includes a noun and is morphologically analyzed in advance, by using information of an expansion dictionary, which includes higher-level categories of the noun, one or more higher-level categories of the expansion dictionary corresponding to the noun included in the utterance into a position before the noun of the utterance to generate an expanded utterance.

Abstract: A generation apparatus 100 includes: an argumentative scheme adding unit 10 which adds an argumentative scheme with respect to pair data constituted by an input utterance and a counter utterance 121 that voices a negative opinion with respect to the input utterance and which generates argumentative scheme-added pair data 122; a generation model learning unit 20 which learns a generation model for generating a counter utterance from an input utterance in consideration of the argumentative scheme by using the argumentative scheme-added pair data 122 as learning data and which generates a learned counter utterance generation model 123; and a counter utterance generating unit 30 which acquires an input utterance of a user and a designated argumentative scheme and which outputs a counter utterance using the counter utterance generation model 123.

Abstract: An utterance information acquisition unit acquires utterance information of a collaborator who performs collaborative work for achieving a task through a dialogue. A dialogue control unit acquires information regarding the process of achieving the task by a plurality of workers performing the collaborative work through a dialogue and generates a system utterance by using an estimation model on the basis of the utterance information acquired by the utterance information acquisition unit, the information regarding the process, and main result information indicating an intermediate result of the collaborative work by the own device. An output unit outputs the system utterance generated by the dialogue control unit to the collaborator.

Abstract: Even when there is a small amount of question response data, a highly accurate response is performed to a user utterance. A question response collection unit (12) collects question response data including a state of a dialog, a question, and a response. A template generation unit (13) generates an utterance template associated with the state on the basis of the question response data. An utterance generation unit (14) generates a system utterance by using the utterance template associated with a state of a current dialog. An utterance presentation unit (15) presents the system utterance to a user. An utterance reception unit (16) receives a user utterance uttered by the user. A state transition unit (17) causes the state of the current dialog to transition on the basis of the user utterance.

Abstract: To make it possible to generate dialogue data for generating a question sentence to deeply delve conversation at a low cost. For each of a plurality of pieces of data each including a set of a first utterance sentence that is a sentence uttered by a first user, a second utterance sentence that is a sentence uttered by a second user and is a response to the first utterance sentence, and a third utterance sentence that is a sentence uttered by the first user and is a response to the second utterance sentence, a dialogue data generation unit 110 generates a set of the first utterance sentence of the data and the second utterance sentence of the data as dialogue data when the second utterance sentence of the data is a question sentence using an interrogative.

Abstract: Acquisition of an utterance pair for expanding a set of utterance pairs for outputting an output utterance in response to receiving a given utterance is described. A keyword extraction unit is configured to compare a degree of characteristic of a word in expansion source utterance pair data and a degree of characteristics of a word in the given utterance data. The expansion source utterance pair data represents a set of expansion source utterance pairs including an input utterance and an output utterance for the input utterance. The present technology includes extracting, based on a comparison result, a keyword list including a keyword that is characteristic of the expansion source utterance pair data. An utterance pair extraction unit is configured to extract, based on the keyword list, an utterance pair from a set of given utterance pairs as an addition for expanding the set of utterance pairs.

Abstract: It is possible to ask an appropriate question for digging an utterance of the other party in depth. An interrogative search unit estimates an estimated used interrogative with a text, which is an utterance sentence, as an input, by using a predetermined rule or an estimator that has already learned, the estimated used interrogative being an interrogative related to the text. A candidate utterance sentence generation unit generates each of candidate utterance sentences for the utterance sentence with the text as an input through automatic utterance generation. Based on each of the candidate utterance sentences and an estimation result of the estimated used interrogative, a ranking unit ranks the candidate utterance sentenced, based on the scored.

Abstract: A conversion device (10) includes: an evaluation unit (11) that estimates which one of subjective evaluation values obtained by quantifying easiness of transmission of a content of a voice felt by a person is to be taken from an input voice signal; and a conversion unit (12) that converts the input voice signal so as to obtain a subjective evaluation value of a predetermined value on the basis of the subjective evaluation value estimated by the evaluation unit (11).

Abstract: Provided are a dialogue device, a dialogue method, a data structure, and a program capable of realizing various dialogues while reducing the amount of description of a dialogue scenario. A knowledge transition unit 120 determines a next type of knowledge based on: a knowledge base 130 in which a relation label indicating each of relations between a plurality of types of knowledge is attached to knowledge about each of utterances to express the knowledge about the utterance; a user utterance; current knowledge; and a dialogue scenario including a basic scenario in which a transition method between the plurality of types of knowledge in the knowledge base is determined using the relation label, and an utterance generation unit 150 generates a system utterance based on the next type of knowledge.

Abstract: An utterance pair for expansion necessary for outputting an appropriate output utterance for an input utterance can be acquired.

Abstract: It is intended to allow learning of a spoken sentence generation model for generating a spoken sentence which enables a discussion covering a wide range of topics. A discussion data storage unit 100 stores a plurality of discussion data sets each including a discussion spoken sentence indicating a discussion topic and a pair of an approving spoken sentence indicating approval for the discussion spoken sentence and a disapproving spoken sentence indicating disapproval for the discussion spoken sentence.

Abstract: An argumentation structure can be automatically extended. A template creation unit 22 creates a template using a predetermined rewriting pattern by receiving, as an input, a proposition represented by each of nodes in an argumentation structure including the nodes respectively representing a main proposition of argumentation and a proposition that functions as an argument for another proposition. An additional proposition output unit 28 creates a proposition functioning as an argument for the input proposition using the created template and outputs the created proposition as a proposition represented by a node to be added to the argumentation structure.
