Driven IFS and Data Analysis

IFS and the Sounds of Literature

The Soundex Algorithm is a method for converting words into 5 digit codes.

The first two digits of the code is determined by the first letter of the word, according to the substitution a = 11, b = 12, ..., z = 36.

The rest of the word contributes the final three digits of the code. First, letters are assigned numbers according to the table

letter	coded as
a,e,i,o,u,y,h,w	not coded
b,f,p,v	1
c,g,j,k,q,s,x,z	2
d,t	3
l	4
m,n	5
r	6

After three digits have been assigned, the rest of the word is ignored.

For short words, missing digits are filled in with 0s.

Adjacent consonants from the same code group contribute only one digit, as do consonants from the same code group separated by w or h.

Finally, ignore a consonant immediately following an initial letter from the same code group.

For example, the first line of Shakespeare's Sonnet 1

From fairest creatures we desire increase

codes as

16650, 16623, 13636, 33000, 14260, 19526
