Discovering common phrases in multiple blocks of text
$500-5000 USD
Paid on delivery
This project will build a tool that will efficiently find common phrases in a large volume of discrete text blocks. The text blocks will be read from a database, and the set of available blocks will grow continually. The tool must be able to use it’s knowledge of the existing set of blocks to process incoming blocks efficiently and find phrases that occur multiple times anywhere in the entire set of text blocks. Most text blocks will be around 1000-6000 words in length, although some may be significantly shorter or longer.

(No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
Requirements:
