Spell Checker for Gurmukhi Script

Abstract

A Spell Checker is a basic necessity for composing text in any language. Though considerable work has been done in the area for English and related languages, the Indian language scenario present a relatively more complex and uphill task. Punjabi is the world‟s 12th most widely spoken language. There is a very little amount of work done in this field. The only available Spell Checker for Punjabi language is „AKHAR‟. First and the far most requirement for any Spell Checker is to have dictionary of different possible words of that language which will act as a corpus. A Spell Checker can be Stand-alone Application capable of operating on a block of text, or as part of a larger application, such as a word processor, email client, electronic dictionary, or search engine. When some Punjabi text is given as an input to Spell Checker, it list outs the incorrect words separately by checking their availability in the dictionary. Finally it provides the suggestions for the incorrect words from the dictionary. In this thesis, I have discussed various types of errors, techniques for detecting and correcting errors and the various Spell Checkers available in different Indian languages. A brief overview of origin and symbols of Gurumukhi Script are explained. In this thesis, I have developed a Spell Checker for Gurmukhi Script. The design, techniques and implementation of the newly developed Spell Checker for Gurmukhi Script are explained. Creation of dictionary, error detection and error correction and replacement are the main features of this system. The system detects approximately 87% of the errors and provides 90% of the correct suggestions.
