This is a pute Python library that allows you to compare texts or strings using an n-gram model and cosine similarity. N-grams are tuples of length n consisting of subsequent tokens from a text. For example, if we treat words as tokens, then the first few trigrams (3-grams) of the license will be:

• 'this work ‘as-is’',
• 'work ‘as-is’ we',
• '‘as-is’ we provide',
• 'we provide no',
• 'provide no warranty'.
• ...

Depending on what you choose as the basic token (words or characters) you can use this library for approximate string matching (finding misspellings, etc.) or as a "good enough" method of checking whether two texts [are similar] Lee.
