Zhifei Zhang · 2013
The rapid development of microblog brings a new carrier for named entity recognition.The paper proposed an approach for named entity recognition on Chinese microblog according to the features of microblog.First of all,the paper normalized the text of the microblog and eliminated the interference caused by non-standard expression,then constructed several knowledge bases,such as Chinese person names,common place names and organization names,and devised feature templates for the recognition method based on conditional random fields.Meanwhile the correct recognition results were added to the knowledge bases to improve the performance of recognition.The experiment results show that our approach is effective to recognize named entities on Chinese microblog.
