COMPUTATIONAL LINGUISTICS
A Monograph in Tamil

Prof. Rajendran Sankaravelayuthan


Abstract

The present monograph entitled “Computational Linguistics” deals mainly with three main aspects: computational linguistics in general, application of computational linguistics for Tamil and technological development of Tamil. The book is divided into 13 chapters.

Chapter 1 Introduction: The introduction first introduces the topic of the book ‘computational linguistics’. It just explains the importance of studying language though computer and their problems, the handling of language in computer, the tools for language study, the skills needed for linguists to involve themselves in computational linguistics, the skills needed for computer scientist to involve themselves in computational linguistics, natural language processing in Tamil, language technology and development of language technology.

Chapter 2 Natural language Processing: Computer and language processing and the regular expressions and automata are discussed elaborately in this chapter.

Chapter 3:Computational phonology: This chapter describes about four aspects of computational phonology: computer phonology in general, certain important information about acoustic phonetics, linguistics issues in text to speech mechanism and speech to text mechanism.

Chapter 4 Computational morphology: This chapter describes about the computer analysis of morphology. It talks further about the computational modeling of morphology. This is followed by a brief description about morphology of Tamil. The attempts to develop morphological analyzer and morphological generator, spell checker for Tamil are also discussed.

Chapter 5 Computational Syntax: This chapter talks about the computational analysis of sentences. Different grammatical formalisms for computational analysis of sentences have been introduced. Shallow parsing is also briefly explained. The aspects of POS tagging, chunking and parsing have been discussed.

Chapter 6 Computational semantics: This chapter talks about linking computational syntax with computational semantics. It also takes about different aspect of computational lexical semantics such as WordNet creation, word sense disambiguation and machine readable dictionaries.

Chapter 7: Spell and grammar checking

Chapter 8: Creation of lexical resources

Chapter 9 Word sense disambiguation

Chapter 10 Machine translation

Chapter 11 Developing computational tools: This chapter briefly talks about developing tools such as machine translation systems, optical character recognition (OCR) and tools for language teaching.

Chapter 12 Technological development of Tamil.

Tamil has initiated its technological development well in advance. It has made use of all the opportunities given to it for making it suitable for digitalization and computerization. The references listed below stand to establish its efforts in fulfilling the need of the day i.e. technological development. Governments, both state and central, funded liberally for the technological development of Tamil. This helped it to develop MT systems, wordNet and other NLP systems. Private organizations also contributed for this mission. Many individuals, both from inside and abroad, literally worked for Tamil computing. The organizations such as CIIL, AUKBCRC, Anna University, Amrita University, Tamil Virtual Academy, Tamil University, and Madras University need to appreciated for their efforts in uplifting Tamil in the era of Information Technology. Tamil has switched over to Unicode abandoning other systems. Tamil has comparatively commendable resouces and tools for NLP applications. Sumptuous amount of text corpora, speech corpora and parallel corpoara are available for Tamil. A good number of speech recognition systems and text to speech systems are developed for Tamil. Reliable morphological analyzers, morphological generators, syntactic parsers, chunkers, shallow parsers, named entiry recogniztion sytems optical character recognition system are available for Tamil. Computational semantics also improved in Tamil. There are attempts to develop word sense disambiguation system, question answering system, relationship extraction system, sentiment analysis systems, automatic summarization systems, and coreference resolution systems. Efforts are made to develop text generation systems too for Tamil. Tamil shows only positive symptoms in the technological development.
