**6. Discussion**

It is possible to obtain a very precise system (accuracy of 99%) but not very efficient with a recall of 10%. In our work, with an accuracy of 97.2% and a recall of 96.4%, we can say that our system is efficient. The use of the fuzzy algorithm in this experiment gave a good result. The advantage of our system is the fuzzy representation that is increasingly used to deal with missing and inaccurate data problems which is the disadvantage of most classification algorithms.
