Method and apparatus for improving performance of approximate string queries using variable length high-quality grams
TL;DR: A computer process called VGRAM as mentioned in this paper improves the performance of these string search algorithms in computers by using a carefully chosen dictionary of variable-length grams based on their frequencies in the string collection.
