Abstract: A syntax analysis method and apparatus are disclosed. The method includes: obtaining a source language sentence that is a translation of a target language sentence (S110); determining instances of state transition for the target language sentence according to the source language sentence and a correspondence between words of the target language sentence and words of the source language sentence (S120); and generating a syntax tree of the target language sentence according to the instances of state transition for the target language sentence (S130). The syntax analysis method and apparatus can improve efficiency of syntax analysis.

Abstract: Disclosed embodiments include a neural network-based translation method, including: splitting the unknown word in an initial translation into one or more characters, and inputting, into a first multi-layer neural network, a character sequence constituted by the one or more characters ; obtaining a character vector of each character in the character sequence by using the first multi-layer neural network, and inputting all character vectors in the character sequence into a second multi-layer neural network; encoding all the character vectors by using the second multi-layer neural network and a preset common word database, to obtain a semantic vector; and inputting the semantic vector into a third multi-layer neural network, decoding the semantic vector by using the third multi-layer neural network, and determining a final translation of the to-be-translated sentence based on the initial translation of the to-be-translated sentence.

Abstract: Embodiments of the present invention provide a translation method and apparatus, and relate to the field of machine translation. The method includes: obtaining a to-be-translated sentence, where the to-be-translated sentence is a sentence expressed in a first language; determining a first named entity set in the to-be-translated sentence, and an entity type of each first named entity in the first named entity set; determining, based on the first named entity set and the entity type of each first named entity, a second named entity set expressed in a second language; determining a source semantic template of the to-be-translated sentence, and obtaining a target semantic template corresponding to the source semantic template from a semantic template correspondence; and determining a target translation sentence based on the second named entity set and the target semantic template.
