An object is to provide an interaction server in which inputs of an input keyword are reduced and the number of exchanges in interaction is reduced as a result. An interaction serverincludes a truth tableconfigured to have question sentences including a sentence to be provided to a user and a plurality of searching keywords associated with, and a relational tableconfigured to have one main keyword and a plurality of related keywords related to the main keyword associated with each other. A search unitacquires at least one of the one main keyword and any of the plurality of related keywords listed in the relational tableon the basis of an input keyword, further performs searching in the truth tableusing the main keyword and/or the related keyword which has been acquired, and acquires a question sentence candidate which is response content corresponding to the main keyword or the related keyword.

The dialogue system includes a keyword acquisition unit configured to acquire an input key group containing one or a plurality of input keywords on the basis of an input of a character string, a category generation unit configured to classify the resulting sentence candidates into a plurality of categories on the basis of a comparison between the input key group acquired by the keyword acquisition unit and the storage key group contained in an FAQ database, an intra-category ranking determination unit configured to determine a priority ranking of the resulting sentence candidates within each of the categories, and a presentation unit configured to select a resulting sentence candidate of a highest priority ranking determined by the intra-category ranking determination unit from within a category of a highest priority ranking determined in advance, and present a response for prompting a user to make an additional input.

Dialogue system

The dialogue system includes a ranking determination unit configured to determine a priority ranking of the resulting sentence candidates on the basis of a degree of coincidence between the input key group and the storage key group, and a presentation unit configured to present a response for prompting a user to make an additional input on the basis of a resulting sentence candidate of a highest priority ranking. In a case where there is the stored keyword which is in a predetermined correspondence relation with the character string, the keyword acquisition unit acquires the input keyword obtained by adding additional information to the stored keyword. In a case where the additional information is added to the input keyword, the ranking determination unit reduces an influence of the input keyword to which the additional information is added on the degree of coincidence.

A question inference device comprises: an input unit inputting an inquiry from a user; a storage unit storing a plurality of questions prepared in advance and one or more keywords for identifying each question in association with each other; a choice unit referring to the storage unit and choosing a question associated with a keyword contained in the inquiry inputted by the input unit from among the plurality of questions; a computation unit computing the likelihood of each of the plurality of questions for the inquiry inputted by the input unit; an inference unit inferring, based on a choice result of the choice unit and a computation result of the computation unit, such a question that the user intends the substance of the question from among the plurality of questions; and an output unit outputting information based on an inference result of the inference unit.

Question inference device

An interaction bot system is an interaction answer system that interacts with a user and provides an answer to a question from the user. The interaction bot system includes a first bot device and at least two or more second bot devices. The first bot device includes a first generation unit configured to generate first narrowing down information for specifying the second bot device corresponding to the question from the user on the basis of the question from the user, and a specification unit configured to specify the second bot device on the basis of the first narrowing down information. The second bot device includes a second generation unit configured to generate second narrowing down information for specifying the answer to the question on the basis of the question from the user, and an answer generation unit configured to generate and output the answer to the question from the user on the basis of the second narrowing down information.

Interaction device and interactive response system

A server is an interactive system that performs the interaction by performing a reverse question with respect to an input by the user and providing response content. An input acquisition unit and an answer generation unit constitute an interaction execution unit that repeatedly performs the interaction until a question sentence and an answer, which are the response content, satisfy a prescribed condition. Further, the stoppage determination execution unit performs control for stopping the interaction performed by the input acquisition unit and the answer generation unit based on the interaction state by the user or the other user. In a case where the interaction is stopped, the output unit provides the question sentence and the answer thereof at the time of stoppage to the communication terminal.

Interactive system

A function execution instruction system includes a function execution instruction unit configured to instruct execution of one or more functions, a sentence input unit configured to input a sentence, an execution function determination unit configured to determine a function the execution of which is instructed on the basis of an input sentence, a time information extraction unit configured to extract time information indicating a time from the input sentence, and a time specification unit configured to, in accordance with a determined function, specify a time used for the execution of the function on the basis of extracted time information wherein the function execution instruction unit instructs the execution of the determined function, which uses a specified time.

Function execution instruction system

A conversation device includes: an inquiry unit configured to output an inquiry including presentation of a key; an acquisition unit configured to acquire an answer; a key accumulating unit configured to accumulate keys included in the inquiry as accumulation keys in a case in which a positive answer for the inquiry is acquired; a candidate question sentence extracting unit configured to extract candidate question sentences including the accumulation keys by referring to a question sentence storing unit configured to store a question sentence and a set of keys included in the question sentence in association with each other; a key selecting unit configured to select an inquiry key that is caused to be included in a next inquiry output by the inquiry unit among a plurality of keys included in the candidate question sentences; and an output unit configured to output one question sentence among the candidate question sentences.

Conversation system

An object is to provide a dialogue server capable of removing an unnecessary keyword from a truth table. A dialogue serverincludes a truth table generation unitextracting one or a plurality of keywords characterizing response content composed of a sentence on the basis of the response content and generating a truth table associating one or a plurality of keywords, from which an unnecessary keyword based on a predetermined condition is removed, of the one or the plurality of keywords, with the response content; a storage unit storing a truth table databaseand an acquisition unitsearching for corresponding response content or a keyword for urging a user to make an additional input on the basis of the truth table databaseupon reception of an input keyword from the user and transmitting the response content or the keyword to the user.

The present invention provides a slip rate estimating device measuring a slip ratio without the need for a body speed and a slip ratio control device using the slip ratio estimating device. A motor torque measured by a torque measuring instrument is input to each of a vehicle model () and an SRE () that performs calculations including time differentiation of the slip ratio. The vehicle model () derives a wheel rotation speed, a wheel rotation acceleration, and a body speed. The vehicle model () outputs the wheel rotation speed and the wheel rotation acceleration to the SRE (). The SRE () outputs the slip ratio based on the motor torque, the wheel rotation speed, and the wheel rotation acceleration.
