There were 3 different aims as classify users based on their gender,age and job consequently.We developed many queries and criterias to determine Twitter Users' classes. We created models which could determine Twitter Users' different classes based on their gender,age and job. We took advantage of machine learning algorithms. In the classification process, we use many data mining algortihms such as Naive Bayes, Random Forest, Random Tree, j48, Support Vector Machine (svm), Sequential Minimal Optimization (smo).As a result of this project, we achived a high success in classification by using comments of Twitter Users.
