    "abstract": "Machine translation from English to Indian languages is always a difficult task due to the unavailability of a good quality corpus and morphological richness in the Indian languages. For a system to produce better translations, the size of the corpus should be huge. We have employed three similarity and distance measures for the research and developed a software to extract parallel data from comparable corpora automatically with high precision using minimal resources. The software works upon four algorithms. The three algorithms have been used for finding Cosine Similarity, Euclidean Distance Similarity and Jaccard Similarity.

For a system to produce better translations, the size of the corpus should be huge. In addition to that, the parallel sentences should convey similar meanings, and the sentences should cover different domains. Modelling the system with such a corpus can assure good translations while testing the model. Since English -Punjabi language pair is an under-resourced pair, this study provides a breakthrough in acquiring English -Punjabi Corpus for performing the task of machine translation. We have employed Statistical methods for the research and developed a software to extract parallel data from comparable corpora automatically with high precision using minimal resources.",
