A Grammar Checking System for Punjabi

This article provides description about the grammar checking system developed for detecting various grammatical errors in Punjabi texts. This system utilizes a fullform lexicon for morphological analysis, and applies rule-based approaches for part-of-speech tagging and phrase chunking. The system follows a novel approach of performing agreement checks at phrase and clause levels using the grammatical information exhibited by POS tags in the form of feature value pairs. The system can detect and suggest rectifications for a number of grammatical errors, resulting from the lack of agreement, order of words in various phrases etc., in literary style Punjabi texts. To the best of our knowledge, this grammar checking system is the first such system reported for Indian languages.
