Thank you for your good question,
we count the affix words that returned correctly to its basic word by each stemming
algorithm,
such as ^kesamaan^ return to ^sama^ by sastrawi, nazief-adriani, but not by arifin setiono
that return it to the word ^kesamaan^.
we used 363 data, but will add to 1000 words of data, in order to represent larger
stemming process and obtain more valid result or comparison
Thank you for your excellent question,
Our research is limited on affix word, that is the word added with suffix, prefix, and
suffix, so the new word or ^slang^ wasn^t included in the data. In addition, slang word is
not listed in Indonesian Dictionary or KBBI.
