Using Signature Hashing for Approximate String Matching

The objective is to demonstrate the expediency of using compressed inverted files with a signature-hashing dictionary for approximate string matching. A comparison of different types of dictionaries is performed and a method based on keyword signature hashing is described. In conclusion, we report the comparative characteristics (search speed, index size, indexing speed) for our search system using compressed inverted files with keyword signature hashing and the Glimpse search freeware.
