Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the translation rule extraction method and the translation method based on the tree-to-tree translation model according to an embodiment of the present invention will be further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] According to a specific embodiment of the present invention, a compressed shared syntax forest is introduced into the tree-to-tree model, in which not an optimal syntax tree for syntax analysis is saved, but as many as tens of thousands of syntax trees may be saved, This improves the accuracy of syntax analysis. Although there are already existing translation methods in the prior art that apply the compressed shared syntactic forest to a tree-to-string translation model. How...

Abstract

The invention provides a translation rule extract method based on a tree-to-tree translation model, comprising the following steps: 1), analyzing source language strings and target language strings in training corpus, and outputting the source language compact shared syntax forest of the training corpus and the target language compact shared syntax forest of the training corpus; and 2), extracting translation rules according to the source language compact shared syntax forest of the training corpus and the target language compact shared syntax forest of the training corpus. Since the testing corpus is translated according to the translation rules, the translation quality is effectively improved.

Description

technical field [0001] The present invention relates to the field of natural language processing, and more specifically, to a language translation rule extraction method and a translation method. Background technique [0002] The syntax-based translation model has gradually become the mainstream model of statistical machine translation. According to whether the syntax tree is built on the source language side and the target language side, the syntax-based translation model can be divided into the following three categories: 1) tree-to-string translation model, such as Liu Yang (Yang Liu) et al. disclosed at the 44th Annual Conference of Computational Linguistics (ACL 2006) in 2006; 2) the string-to-tree translation model, Ma Ku et al. 3) a tree-to-tree translation model, such as that disclosed by Eisler et al. at the 41st Annual Conference on Computational Linguistics in 2003. [0003] The existing tree-to-tree translation model establishes a unique syntactic tree on the so...
