In a machine translation system, a default translation flag for indicating a default equivalent word is set in a dictionary in a memory. A normal equivalent-word selector of a translation module executes semantic analysis on a case structure tree determined by a dictionary-lookup morpheme analyzing part, a syntax analyzer, and a tree structure transforming unit. If the case structure tree has failed in the semantic analysis, a special equivalent-word selector executes a default translation processing to adopt the default equivalent word indicated by the default translation as an optimum equivalent word such that the case structure tree is passed. Thus, even if the case structure tree has failed in the semantic analysis due to strict semantic restrictions, a translation can be securely generated. Further, if the case structure tree has not failed in the semantic analysis, a high-accuracy translation can be generated.
