Abstract: A string similarity apparatus, method, and computer readable medium which manages caching of resources. The method includes storing a plurality of software instructions, executing the plurality of software instructions, such as, determining a first number of characters contained by a first string, determining a second number of characters contained by a second string, determining a larger number from among the first number and the second number, setting the larger number to a string length value, determining a maximum number of subsequent characters from the first strings which match subsequent characters from the second string and setting the value, setting the maximum number to a maximum group size value, calculating a resulting value by subtracting the maximum group size value from the string length value, and outputting the resulting value which represents a computational cost of converting the first string into the second string.
