string_score

Ported from version 0.1.10 of Joshaven Potter's string_score.

string_score is a string ranking algorithm that produced a number between 0 and 1 representing the similarity between two strings.

Usage

#include "string_score.h"
#include <string.h>
#include <stdio.h>

int main( int argc, char** argv )
{
    char* a = argv[1];
    char* b = argv[2];
    printf( "normal match: %1.10lf\n", string_score( a, b ) );
    printf( "fuzzy match:  %1.10lf\n", string_fuzzy_score( a, b, 0.5 ) );
    return 0;
}

(See the original string_score javascript code for details on the algorithm.)

Running the benchmark

To run the benchmark cd into the string_score/benchmark folder and run the following commands:
