Problems solved by technology

[0003] The present invention provides a method for constructing a Vietnamese dependency tree bank based on a Chinese-Vietnamese word alignment corpus, which is used to solve the problem that the prior art is difficult for studying Vietnamese dependency syntax analysis, and building a Vietnamese dependency tree bank is relatively scarce. Problem, the Vietnamese language dependency tree bank constructed by the present invention can provide strong support for upper-level applications such as syntactic analysis, machine translation, and information acquisition of Vietnamese

Embodiment 1

[0025] Embodiment 1: as Figure 1-3 Shown, a kind of method based on Chinese-Vietnamese word alignment corpus constructs Vietnamese language dependency tree bank, described concrete steps of the method for building Vietnamese language dependency tree bank based on Chinese-Vietnamese word alignment corpus are as follows:

[0026] Step1. First, build a Chinese-Vietnamese word alignment parallel sentence pair database;

[0027] Step1.1, first collect Chinese-Vietnamese parallel sentence pairs;

[0028] Step1.2. Construction of Chinese-Vietnamese parallel sentence pair library with word alignment; use GIZA++ for word alignment training on Chinese-Vietnamese parallel sentence pairs, and then obtain Chinese-Vietnamese word-aligned parallel sentence pair library through manual adjustment;

[0029] Step2. Build a Chinese dependency tree corpus;

[0030] Step2.1. Perform Chinese sentence segmentation processing on the Chinese-Vietnamese word alignment parallel sentence pair library; ...

Abstract

The present invention relates to a method for constructing a Vietnamese dependency tree bank on the basis of Chinese-Vietnamese vocabulary alignment corpora and belongs to the technical field of natural language processing. According to the present invention, firstly, a Chinese-Vietnamese vocabulary alignment sentence pair library is constructed; then a Chinese dependency tree corpus is constructed; and according to the constructed Chinese-Vietnamese vocabulary alignment sentence pair library and Chinese dependency tree corpus, a Vietnamese dependency tree corpus is constructed. The Vietnamese dependency tree bank constructed by the method can provide powerful support for upper layer applications of syntactic analysis, machine translation, information acquisition and the like; a bilingual parallel dependency tree corpus is constructed; according to the method for constructing a dependency tree, which is disclosed by the present invention, the process of manually collecting and labeling the Vietnamese dependency tree bank is simplified and labor and time of constructing the tree bank are saved; and compared with a method adopting a machine to carry out learning, the method for constructing a dependency tree, which is disclosed by the present invention, is obviously improved in accuracy.

Description

technical field [0001] The invention relates to a method for constructing a Vietnamese dependency tree bank based on a Chinese-Vietnamese word alignment corpus, and belongs to the technical field of natural language processing. Background technique [0002] The China-ASEAN Free Trade Area is the most populous free trade area in the world. The "Bridgehead Strategy" is a strategic need to promote my country's southwest development and realize good-neighborliness and friendship with ASEAN countries. Yunnan is an important bridgehead for China's opening to the southwest. Language Communication is the prerequisite for political, cultural and economic exchanges between China and ASEAN countries. Vietnam, a member of ASEAN, is connected by mountains and rivers to Yunnan. The people of the two countries have a long history of exchanges. Language communication has played a very important role in the friendly coexistence and mutual learning of the people on the border between the two s...
