Unified semantic representation for entities and documents-the probability distribution obtained from a random walk on a subgraph of the knowledge based was adopted. According to this distributed representation, the entities that are similar with mentions as the linking results was obtained. This method achieved 0.665 F value on entity linking section of TAC 2015 TEDL task, it performs better than other participating systems. It is illustrated that the method can overcome the feature sparsity issue and is less amenable to feature sparsity bias. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2016-220
