Abstract: A non-transitory computer-readable recording medium storing a specifying program for causing a computer to execute processing including: acquiring a first value that indicates a result of inter-document distance analysis between each of a plurality of sentences stored in a storage unit and an input first sentence; acquiring a second value that indicates a result of latent semantic analysis between each of the sentences and the first sentence; calculating similarity between each of the sentences and the first sentence on the basis of a vector that corresponds to each of the sentences and has magnitude based on the first value acquired for each of the sentences and an orientation based on the second value acquired for each of the sentences; and specifying a second sentence similar to the first sentence among the plurality of sentences on the basis of the calculated similarity between each of the sentences and the first sentence.

Abstract: A non-transitory computer-readable recording medium records an output control program for causing a computer to execute processing of: in a case where input of a question is accepted, extracting an accuracy of each of one or a plurality of answers to the question, the accuracy being stored in a storage unit; and selecting an answer to be output from the one or plurality of answers so that a total value of the accuracy of the one or plurality of answers to the question is equal to or larger than a first threshold.

Abstract: A non-transitory computer readable recording medium records a conversation control program that causes a computer to execute processing including: receiving an instruction to change a specific input message among messages displayed in times series to another input message; and displaying the other input message and a response message to the other input message in time series.
