  • What is it?

    "fingerprint" module generates fingerprints of a document.

  • Fingerprint!!!! :(, What is that?

    Fingerprint is like the signature of the document. More specifically, in our context, it is the subset of hash values calculated from the document.

  • Okay i now know about it a bit, tell me how it calculates fingerprints?

    Generation of fingerprints of a document is a three stage process;

    • (1st phase) generates the k-grams from the standard string
    • (2nd phase) generates the hash values for each k-gram using rolling hash function
    • (3rd phase) generates the fingerprints from the hash values using winnowing

  • How can i install it on my machine?

    You can install it in basically two ways;

    • using source
      1. git clone git@github.com:kailashbuki/fingerprint.git
      2. cd fingerprint
      3. sudo python setup.py install
    • using pip
      1. sudo pip install fingerprint

  • Hmm! ... How can i use it?

    It's plain simple. Here's an example for you;

            from fingerprint.fingerprintgenerator import file_content_refiner, FingerprintGenerator

            # You could get the standard string from a document as;
            s = file_content_refiner("path/to/file")
            # OR you could directly pass the standard string if you have
            s = "some sample string"

            fpg = FingerprintGenerator(input_string=s)
            fpg.generate_fingerprints()
            print fpg.fingerprints
