The embodiment of the invention provides an unregistered word processing method based on single semantics, an intelligent question answering method and an intelligent question answering device. The unlogged-in word processing method comprises the steps that at least one semantic meaning of an unlogged-in word is obtained, and each semantic meaning comprises at least one meaning; selecting a reference semantic from the semantics of the unlogged-in words; generating semantic vectors of the unregistered words according to the reference semantics; and performing randomization processing on the semantic vector according to the random word vector to generate a simulation word vector of the unregistered word. Therefore, the simulation word vector generated through the technical scheme provided bythe invention can express the semantics of the unlogged-in words; as the randomization processing is carried out, the random variability is realized; Therefore, when the random word vector generatedby the embodiment of the invention is used for an intelligent question and answer system to generate the response, the correlation degree of the response and the question can be high, and the responsecan be diversified, so that repeated and monotonous response is avoided, the user experience is improved, and the problem of unregistered words is solved.
