Abstract: A method and an apparatus for generating sentences capable of generating more natural and easily comprehensible sentences by incorporating the selection of an appropriate choice for the form of expression or the order of words from a number of possible candidates in a process of sentence construction. In the apparatus, conceptual structures to be utilized as elements of sentences to be generated are stored; rules to be followed in generating sentences are stored; and sentences are generated from the stored conceptual structures in accordance with the stored rules by utilizing sizes of partial structures of the conceptual structures specified by the stored rules to determine a sentence structure of the sentence to be generated.

Abstract: A translation communication system having memory means for storing past communication information and past translated information including as original word/translated word pair obtained from the communication information, and supply means for supplying the translated information useful for determining the translated word candidate to the translation means. With this construction, when the translation means translates a first language into a second language in conversation, the supply means retrieves the communication information in the first language from the memory means in accordance with the input original sentence in the first language, and supplies an original word/translated word pair in accordance with the retrieval result. Therefore, as the translated word in the second language, the present system uses the same word as the original word previously input by the other side's operator who uses the second language.
