چکیده

This paper presents a novel method for multistage dependency parsing based on dependency direction. In the method, dependency parsing processes are divided into multiple sub-stages, and each stage is in a sequential pattern, which makes it easier to take applicable solutions for different issues in dependency parsing. Meanwhile, dependency parsing in the previous stage provides a clearer context for next stage. Furthermore, due to the dependency direction, the proposed method has lower search complexity than that of classic graph-based methods. Experimental results show that compared with common methods, the proposed method in this paper offers comparable accuracy and higher efficiency.

An improved joint model: POS tagging and dependency parsing

Dependency parsing is a way of syntactic parsing and a natural language that automatically analyzes the dependency structure of sentences, and the input for each sentence creates a dependency graph. Part-Of-Speech (POS) tagging is a prerequisite for dependency parsing. Generally, dependency parsers do the POS tagging task along with dependency parsing in a pipeline mode. Unfortunately, in pipel...

Multi-view Chinese Treebanking

We present a multi-view annotation framework for Chinese treebanking, which uses dependency structures as the base view and supports conversion into phrase structures with minimal loss of information. A multi-view Chinese treebank was built under the proposed framework, and the first release (PMT 1.0) containing 14,463 sentences is be made freely available. To verify the effectiveness of the mu...

Dependency parsing for Chinese long sentence: A second-stage main structure parsing method

This paper explores the problem of parsing Chinese long sentences. Inspired by human sentence processing, a second-stage parsing method, referred as main structure parsing in this paper, are proposed to improve the parsing performance as well as maintaining its high accuracy and efficiency on Chinese long sentences. Three different methods have attempted in this paper and the result shows that ...

Why is German Dependency Parsing More Reliable than Constituent Parsing?

In recent years, research in parsing has extended in several new directions. One of these directions is concerned with parsing languages other than English. Treebanks have become available for many European languages, but also for Arabic, Chinese, or Japanese. However, it was shown that parsing results on these treebanks depend on the types of treebank annotations used [ , ]. Another direction ...

A subtree-based factorization of dependency parsing

We propose a dependency parsing pipeline, in which the parsing of long-distance projections and localized dependencies are explicitly decomposed at the input level. A chosen baseline dependency parsing model performs only on ’carved’ sequences at the second stage, which are transformed from coarse constituent parsing outputs at the first stage. When k-best constituent parsing outputs are kept, ...
