Table 2: Comparison to state-of-the-art unsupervised systems, “-SC” means without sentence constraint
['[EMPTY]', 'Prec', 'Recall', 'F1']
Our model has outperformed all of the previous methods. The improvement of recall is due to the normalized cut criteria, which can better use the inner connectivity between entities. The sentence constraint improves the result one step further.
