Recall shows the amount of correct normalizations over the words that require normalization (ill-formed OOV words).
we extended the candidate list obtained through contextual similarity as described in the previous section, by including all the tokens in the word association graph that satisfy the edit distance and 3 an approximate string comparison measure (between 0.0 and 1.0) using the edit distance https://sourceforge.net/projects/febrl/ phonetic edit distance criteria.
