A Deterministic Dependency Parser for Japanese

Feature Engineering in Persian Dependency Parser

Dependency parser is one of the most important fundamental tools in the natural language processing, which extracts structure of sentences and determines the relations between words based on the dependency grammar. The dependency parser is proper for free order languages, such as Persian. In this paper, data-driven dependency parser has been developed with the help of phrase-structure parser fo...

KN Parser : Japanese Dependency / Case Structure Analyzer

This paper presents the KN parser, a Japanese dependency/case structure analyzer. It performs well in parsing Japanese sentences by taking account of certain characteristics in Japanese language. Several unique methods used in the parser are discussed and preliminary evaluation results on hundreds of Japanese sentences are given.

A Three-Step Deterministic Parser for Chinese Dependency Parsing

This paper presents a three-step dependency parser to parse Chinese deterministically. By dividing a sentence into several parts and parsing them separately, it aims to reduce the error propagation coming from the greedy characteristic of deterministic parsing. Experimental results showed that compared with the deterministic parser which parsed a sentence in sequence, the proposed parser achiev...

Optimizing a Deterministic Dependency Parser for Unrestricted Swedish Text

Using a Partially Annotated Corpus to Build a Dependency Parser for Japanese

We explore the use of a partially annotated corpus to build a dependency parser for Japanese. We examine two types of partially annotated corpora. It is found that a parser trained with a corpus that does not have any grammatical tags for words can demonstrate an accuracy of 87.38%, which is comparable to the current state-of-the-art accuracy on the Kyoto University Corpus. In contrast, a parse...
