Easy accessibility and light content filtering attempt have made microblogging sites the most popular platforms for users to share their experiences and express their opinions.Extracting from the user-composed microblogs the opinions expressed are of great significance for many practical applications.However,such task is very challenging,in particular for Chinese Microblogs.A novel representation of the opinions expressed in microblog sentences is presented and a recurrent neural network(RNN) based sequence labeling approach is proposed about sentiment parsing of Chinese microblogs.The experiments evaluate the performance of different RNN models and explore the bi-directional and deep versions of each model on a Chinese microblog corpus built by this paper.Experimental results show that the bidirectional version of the gated recurrent unit(GRU) model with three layers achieves the highest F-score 0.622.

Easy accessibility and light content filtering attempt have made microblogging sites the most popular platforms for users to share their experiences and express their opinions.Extracting from the user-composed microblogs the opinions expressed are of great significance for many practical applications.However,such task is very challenging,in particular for Chinese Microblogs.A novel representation of the opinions expressed in microblog sentences is presented and a recurrent neural network（RNN） based sequence labeling approach is proposed about sentiment parsing of Chinese microblogs.The experiments evaluate the performance of different RNN models and explore the bi-directional and deep versions of each model on a Chinese microblog corpus built by this paper.Experimental results show that the bidirectional version of the gated recurrent unit（GRU） model with three layers achieves the highest F-score 0.622.
