One of these social networks is Twitter - a microblogging hub and rich environment of data. Scanning tweets online is a hard task and searching effortlessly to find intended topic from huge amount of data is also time consuming. This paper is intended to propose a solution of collecting Twitter of the corpus دبي (Dubai) by using Zapier website and storing them in Google sheet. Then, creating a word vector to the tweets by using TF-IDF methodology. After this, log results into k- mean clustering algorithm with cosine similarity to measure similarity between objects of each cluster. The results demonstrate that internal evaluation techniques failed to evaluate quality of the cluster. In addition to that, interesting topics was found about دبي (Dubai). Moreover, better results achieved by using Filter Tokens (by Region) than without using it.
