چکیده

This paper presents a joint model for morphological and dependency analysis based on automatically acquired lexical knowledge. This model takes advantage of rich lexical knowledge to simultaneously resolve word segmentation, POS, and dependency ambiguities. In our experiments on Japanese, we show the effectiveness of our joint model over conventional pipeline models.

Hierarchical Word Structure-based Parsing: A Feasibility Study on UD-style Dependency Parsing in Japanese

In applying word-based dependency parsing such as Universal Dependencies (UD) to Japanese, the uncertainty of word segmentation emerges for defining a word unit of the dependencies. We introduce the following hierarchical word structures to dependency parsing in Japanese: morphological units (a short unit word, SUW) and syntactic units (a long unit word, LUW). This paper describes the results o...

Arabic Parsing Using Grammar Transforms

We investigate Arabic Context Free Grammar parsing with dependency annotation comparing lexicalised and unlexicalised parsers. We study how morphosyntactic as well as function tag information percolation in the form of grammar transforms (Johnson, 1998, Kulick et al., 2006) affects the performance of a parser and helps dependency assignment. We focus on the three most frequent functional tags i...

Joint Morphological and Syntactic Analysis for Richly Inflected Languages

Joint morphological and syntactic analysis has been proposed as a way of improving parsing accuracy for richly inflected languages. Starting from a transition-based model for joint part-of-speech tagging and dependency parsing, we explore different ways of integrating morphological features into the model. We also investigate the use of rule-based morphological analyzers to provide hard or soft...

Capturing Consistency between Intra-clause and Inter-clause Relations in Knowledge-rich Dependency and Case Structure Analysis

We present a method for dependency and case structure analysis that captures the consistency between intra-clause relations (i.e., case structures or predicate-argument structures) and inter-clause relations. We assess intra-clause relations on the basis of case frames and inter-clause relations on the basis of transition knowledge between case frames. Both knowledge bases are automatically acq...

Detecting Sentence Boundaries in Japanese Speech Transcriptions Using a Morphological Analyzer

We present a method to automatically detect sentence boundaries(SBs) in Japanese speech transcriptions. Our method uses a Japanese morphological analyzer that is based on a cost calculation and selects as the best result the one with the minimum cost. The idea behind using a morphological analyzer to identify candidates for SBs is that the analyzer outputs lower costs for better sequences of mo...
