Embodiment 1

[0061] Such as Figure 15 As shown, this embodiment provides a client / server system block diagram of a syntactic tree tagging platform that facilitates public participation. It can realize the function of multiple people marking at the same time, and it can run on a local server or a remote cloud server. This embodiment takes the syntax tree labeling of phrase structure as an example, and its working process is described as follows:

[0062] 1. Enter a sentence

[0063] Suppose you input a sentence "w1, w2, w3, ..., Wn" containing n words, such as image 3 , which has been pre-segmented by the word segmentation tool. For the sake of illustration, it is assumed here that the word "W2" is composed of 2 characters, the word "W5" is composed of 3 characters, and the rest of the words are composed of 1 character.

[0064] 2. Word segmentation tagging

[0065] Although the word segmentation tool is used for automatic word segmentation in advance, since the word segmentation too...

Abstract

The invention provides a syntax tree library construction system. The syntax tree library construction system mainly comprises a word segmentation annotation module, a word meaning annotation module,a chunk connection module, a component identification and component relationship annotation module and a syntax tree proofreading module. More people can participate in syntax tree construction work,so that a large-scale, multi-field and high-quality syntax tree library is constructed. The problems that a traditional syntax tree construction method is high in cost, low in efficiency, poor in consistency, small in scale, narrow in field, slow in updating and the like are solved. The problems that labeling operation can only be conducted on a large screen and the like are also solved.

Description

technical field [0001] The present invention relates to the technical field of syntactic analysis in natural language processing, in particular to a syntactic tree library construction system. Background technique [0002] A syntax tree is a syntactic analysis result of a natural language sentence expressed in a tree structure. Each node of the syntax tree is marked with rich information to describe the granularity of the syntactic analysis. The syntactic treebank constructed from a large number of syntactic trees is an important resource for machine automatic syntax analysis, especially the syntax analyzers with supervised learning can only be applied after being trained by the syntactic treebank. At present, there are already some artificially constructed syntactic treebanks, such as the Pennsylvania Treebank PTB (English) and CTB (Chinese), Tsinghua Chinese Syntactic Treebank TCT, Taiwan Sinica Chinese Treebank, etc. These different syntactic treebanks have their own dif...
