Two problems arise when using distant su- pervision for relation extraction. First, in this method, an already existing knowl- edge base is heuristically aligned to texts, and the alignment results are treated as la- beled data. However, the heuristic align- ment can fail, resulting in wrong label problem. In addition, in previous ap- proaches, statistical models have typically been applied to ad hoc features. The noise that originates from the feature extraction process can cause poor performance.
