According to one embodiment, an interactive system includes following units. The knowledge reference unit refers to a question-answering knowledge based on a result of analyzing an input sentence to acquire a candidate for an answer to the input sentence. The unknown keyword detection unit detects, from the input sentence, an unknown keyword. The related keyword estimation unit acquires, in response to the detection of the unknown keyword, one or more candidates for a related keyword having a meaning close to the unknown keyword from predetermined keywords. The response generation unit generates a response to the input sentence based on the one or more candidates for the related keyword when the unknown keyword is detected.
