Abstract

Aiming at the problem that traditional entity alignment method could not reflect latent semantic information, this paper optimized it, making the effect of entity alignment more significant. It used the LDA model to model the unstructured data of the network encyclopedia, and adopted the improved BP algorithm to solve the hidden parameters of LDA model, in turn, generated entity eigenvectors to perform similarity calculation. Finally, through calculation results could determine whether alignment. The experimental results show that, through comparing with three kinds of traditional algorithms, the proposed algorithm increases the three-evaluation index that above precision, recall and F-score. Aiming at the network encyclopedia entity with description information, the algorithm can effectively improve the entity alignment effect.
