Abstract  

[Objective] This paper presents a new model for public opinion monitoring system based on Hadoop to retrieve and analyze information from the micro-blog platforms. [Methods] We first surveyed the existing technology of the public opinion monitoring systems and proposed a new model with modified algorithm. Then, we built a big data analysis platform with Hadoop to examine the model’s feasibility through experimental simulations. [Results] The proposed model can detect and retrieve public opinion data effectively. [Limitations] The Hadoop cluster was relatively small. We did not compare our model with other clustering algorithms to discuss their advantages and disadvantages. [Conclusions] The proposed model can conduct public opinion analysis with micro-blog data and provide scientific information for the policy makers to improve crisis management.
