This has become one of the most active research fields in Natural Language Processing. In recent years sentiment analysis for Vietnamese text has received a considerable attention. In the fourth international workshop on Vietnamese language and speech processing there was a competition between various researchers in solving this problem based on a benchmark dataset provided by the workshop committee. However each researcher address the problem with different methods. In this paper we present a comparison of a large number of machine learning algorithms for tackling this problem. The results of the experiments help to gain insight into the ability of various machine learning algorithms when used for Vietnamese sentiment analysis.
