Abstract: India is a multilingual, linguistically dense and diverse country with rich resources of information. Parallel corpora have major role in multilingual natural language processing, computational linguistics, speech and information retrieval. This paper describes an alignment system for aligning English-Hindi texts in GyanNidhi corpus at the sentence level. The criteria used for alignment is combination of linguistic, statistical information and simple heuristics. We use multi-feature approach with Anusaaraka (Machine Translation System), Hindi shallow-parser, Hindi WordNet lookup as primary technique with resources of target language to increase the level of alignment accuracy. Other features such as Named Entities, linguistic information, notation converters are used to match the words in between one-to-many bilingual sentences. Our experiments are based on the GyanNidhi corpus. We obtained 92.06% accuracy for English-to-Hindi sentence alignment with 95.68% precision and 88.09% recall for one-to-many sentence alignment. The study also suggests procedures for aligning parallel translated corpora by using a machine translation system.
