Description of method disadvantage usually uses words that carry negation meaning like
cannot, problem, disadvantage, weakness. The rules and examples are given in Table 4. Unlike
disadvantage description, no frequent feature words are used in advantage description. The
description usually uses certain positive words which are listed in Table 5. We can extract positive
words and then use these words to recognize advantage.
