Abstract: An information processing system includes a user terminal that receives input from a user; an operator terminal that receives input from an operator; and one or more information processing apparatuses connected to the user terminal and the operator terminal. The information processing system includes circuitry configured to: acquire identification information from the user terminal and input information input to the user terminal; search response information for the input information; respond to the user terminal with the response information in response to the input information; determine, based on the identification information acquired from the user terminal, whether to perform a switching operation to perform a chat between the user terminal and the operator terminal; and control the switching operation based on a determination result.

Abstract: An information processing apparatus connectable with a user terminal via a network, includes circuitry configured to acquire information input to the user terminal by a user; search response information to be responded to the input information; respond, to the user terminal, a response message based on the response information to the input information; set a plurality of modes each used for performing a dialogue with the user terminal; and store history information of the dialogue that is performed with the user terminal using each of the plurality of modes in a memory.

Abstract: An information processing system, an information processing apparatus, and an information processing method. The information processing system stores in one or more memories, scenario information for associating a scenario with an object for leading from question information to answer information in the scenario, receives input information from a terminal device and transmit response information responding to the input information to the terminal device based on the scenario information, receives a change to the object included in the scenario information, and determines whether a parent object having a corresponding relationship with a child object for which the change has been received exists.

Abstract: A search apparatus includes a memory and circuitry. The memory is configured to store second sentences in association with past-input first sentences, and store synonyms corresponding to each of a plurality of words. The circuitry is configured to divide each of the past-input first sentences into words and divide a newly-input first sentence into words; select, from the synonyms corresponding to each of the plurality of words, synonyms corresponding to each of the words obtained by dividing each of the past-input first sentences, in descending order of appearance frequency of the words; store the selected synonyms; detect, from the selected synonyms, synonyms corresponding to each of the words obtained by dividing the newly-input first sentence; and retrieve, from the memory storing the second sentences, at least one of the second sentences corresponding to the newly-input first sentence based on the detected synonyms and the words of the newly-input first sentence.

Abstract: An information processing system and an information processing method. The information processing system acquires input information input to the user terminal, searches response information for the input information, responds to the user terminal with the response information in response to the input information, determines whether to display a switching reception screen configured to receive a switching operation to perform a chat between the user terminal and the operator terminal, and displays the switching reception screen on the user terminal based on determination result.
