Abstract: An entity linking approach based on convolutional neural network and random walk with restart was presented. This method first discovers the mentions in the text, after generates the mention candidate entity set, then selects the candidate entity using the entity linking approach based on convolutional neural network and random walk with restart and clusters the mentions those do not have the corresponding entity in the knowledge base. Our method FCEAFm is 0.652 on the TAC-KBP2016 entity discovery and linking evaluation data set, and the first team is 0.643. The results show our method can effectively solve this problem.

Key words: entity linking, convolutional neural network, random walk with restart
