# PICAD (protein interaction corpus with annotated directions) corpus for protein interactions. Last modified on May 16, 2011. # Please cite: # Mixture of logistic models and an ensemble approach for protein-protein interaction extraction. Lindsey Bell, Jinfeng Zhang and Xufeng Niu, ACM-BCB 2011, accepted. # Note: not all the protein names are tagged in the corpus and not all the true interactions have been annotated. # We may update this corpus in the future. # notations: # e1, the position of the first protein # name1, the first protein name in the sentence # e2, the position of the second protein # name2, the second protein name in the sentence # iwpos, the position of interaction word # iw, the interaction word in the sentence # dir, direction of the interaction, NA, ab (e1 act on e2, A regulates B) or ba (e2 act on e1, A is regulated by B). # class, the classification of the triplet, t or f.
