Dependency Framework for Marathi Parser

Yogesh Vijay Umale


Abstract

This paper describes the Framework of Dependency Grammar for Marathi Parser. Dependency grammar is a grammar formalism, which is a capture direct relations between word to word in the sentence. The parser is a tools, which is automatic analysis sentence and draw a syntactic tree of sentence. The grammar formalism is mechanism to developing parser. Today in filed of computational linguistics, natural language processing and artificial intelligent have two kind of grammar formalism which is Phrase structure grammar and Dependency grammar. Both grammar formalism have their own limitation to developing a parser. In this paper I will use computational Panini grammar approach of dependency grammar. Computational Panini grammar has 37 dependency tag-set and those tag-sets are useful to annotate the Indian languages such as Hindi, Telugu and Bangla. However, I have to examine those dependency tag-set to Marathi and annotate a corpus which is useful to develop a Marathi parser. To annotate data I have use an Anno-Corp Guidelines, which develop by IIIT, Hyderabad. According to guidelines the relations are three types karaka relations, which is mark as k1,k2,k3,k4,k5 and k7, non-karaka relations which marked as r6,r6-k1,r6-k2,rt,rd,rh,ras_k*, adv, and other relations such as relative clauses.

Keywords: Marathi, Parser, Dependency Framework, Corpus Annotation.

Introduction

The Parser is tools which used to analysis the sentence in term of its constituent parts. A parser aims to generate automatic syntactic trees of natural language. In filed of computational linguistic, natural language processing language and artificial intelligent have two kind grammar formalism which phrase structure grammar and dependency grammar. Those two grammar mechanism are useful to develop a Parser. Today English language have phrase structure grammar formalism and dependency grammar formalism to develop parser and those two grammar formalism are provide good accuracy. When we apply those two grammar formalism to Indian languages, than we can see dependency grammar is provide good accuracy compared to phrase structure grammar. The reason is simple, English language have positional word order structure and most of the Indian languages have free word order structure and morphological rich.“Development of a parser is a challenging task for morphological rich and free word languages such as Indian languages. Dependency grammar formalism is suitable and useful for Indian languages”(Bharati, et al, 1995).
