Since some social media text messages are extremely short and contain several OOV words, they do not provide sufficient context, i.e., IV neighbors, to enable the extraction of good candidates from the word association graph.
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.
