14. A string similarity assessment system, comprising: a memory storing instructions that, when executed, are configured to: receive a plurality of input strings comprising characters from a character set; generate hashtables for each respective input string using a hash function that assigns the characters as keys and character positions in the strings as values; determine a character similarity index for at least two of the input strings relative to each other by comparing a similarity of the values for each key in the their respective hashtables; determining a total disordering index based representative of an alignment of the at least two input strings by determining differences between a plurality of index values for each individual key in their respective hashtables and determining the total disordering index based on the differences; and determining a string similarity metric based on at least one character similarity index and the total disordering index; and one or more processors configured to execute the instructions.

The system of claim 14 , wherein the string similarity metric is determined by the following equation: 1 - (  m 2 2 + 1  - o  m 2 2 + 1  * m - s AB m ) where m is a length of the longer string of the at least two strings, where o is the total disordering index, and wherein s AB is a greater of the character similarity indices for at least two of the input strings.
