Abstract:

A new clustering based denoising method was proposed, with the help of clustering and recognizing patterns of sentences that express a relationship, to reduce the noisy data that was introduced in the alignment step of traditional distant supervision method. The experimental results demonstrate that our approach can significantly improve the accuracy of relation extraction system.
