This study is to analyze the behavior of the user Based on the dataset of WoWAH( World of Warcraft Avatar History) on the Internet by classifying the game users. First, We need to take out the Avatar ID of all users from the data and calculate the time that it takes for each level of the user. Next, the user can be separated to many groups by using the K-means algorithm. On this section, the effect of the k-means algorithm is affected by the method of calculating the similarity. we compare the results to get the best number of groups by experiment using different numbers of groups. Finally, on the basis of the result, we can check the user's characteristics by comparing the groups that users are classified.
