A new TAG Formalism for Tamil and Parser Analytics

TL;DR

This paper introduces a simplified TAG formalism tailored for Tamil, addressing previous complexities by focusing less on morphology and providing a parser implementation with notable variations from existing systems.

Contribution

The paper presents a minimalistic TAG formalism for Tamil and a corresponding parser, simplifying previous approaches and adapting the XTAG system for Tamil language processing.

Findings

Successfully designed a simplified TAG for Tamil

Developed a parser with variations from XTAG

Demonstrated effectiveness on Tamil language data

Abstract

Tree adjoining grammar (TAG) is specifically suited for morph rich and agglutinated languages like Tamil due to its psycho linguistic features and parse time dependency and morph resolution. Though TAG and LTAG formalisms have been known for about 3 decades, efforts on designing TAG Syntax for Tamil have not been entirely successful due to the complexity of its specification and the rich morphology of Tamil language. In this paper we present a minimalistic TAG for Tamil without much morphological considerations and also introduce a parser implementation with some obvious variations from the XTAG system
