With the rapid development of information technology, the amount of data has grown exponentially. The birth of cloud computing directly sent us into the era of big data. In view of the uncontrollable factors of online commentary, how to effectively mine the hidden consumer experience and control the negative experience communication from massive online reviews has become the key to building a dynamic “green†network environment in current big data era. This paper is based on machine learning to mine online comments and proposes an online commentary emotional early warning model, which realizes online emotional monitoring based on intelligent information processing to a certain extent.
