Disclosed are an ideographical member identification and extraction method and a machine-translation and manual-correction interactive translation method thereof. The ideographical member identification and extraction method is using corpuses with the same contents in a multi-language or bilingual word version, aligning sentences to generate a double-statement opposite library, different languages and characters being related through ideographical expressions, and the ideographical expressions of different languages and characters being achieved through four identical ideographical members. Identifying and extracting the four identical ideographical members comprises a sentence reading matched frame, an identification and label sentence cabin, a cabin detection and extraction cabin model and a receiving and storing sense-group cluster. The present invention further provides a machine-translation and manual-correction interactive translation method based on the ideographical members, comprising: reading sentences with a frame, setting a source statement, transferring sentence cabin or cabin eye contents, saving the inquiry items, pre-selecting given target langue sentences to be corrected and correcting semantic meanings, and self learning. The present invention solves the technical problem in the prior art, that quality of translation texts is poor, an operator is needed to have independent translation ability, and loss of word meanings and semantic meanings can not be redeemed in a processing process.
