We collected data from social networks, and for each word, we used the algorithm based on Soundex described in Section 4.2.1. to get all the words sharing the same phonetic codes.
a cleaning process is done on each entry: removing the words (bold examples in Table 6) that are not related to the entry, removing the words (in italic in Table 6) which are similar, but they do not have the exact meaning as the entry and adding the missed words (examples in blue in Table 7).
