... clas- sified into question types without using them in the training phase. The results of automatic evaluation of complete matching are in Top5 (T5), and MRR and partial matching are in Top5 (T5’) and MRR’. It ... Discussion Our approach needs no question type system, and it still achieved 0.36 in MRR and 0.47 in Top5. This performance is comparable to the results of SAIQA- II (S...

... such as Phe295(288)andPhe297(290), and the peripheral anionic site such as Asp74(72), Tyr72(70), Tyr124(121), and Trp286(279) contribute to the binding of E2020 to AChE. Asp74 and Trp86 are present ... present in both AChE and BChE, and the mutation of Trp86 (Trp82 in BChE) to a nonaromatic residue has a dramatic effect on the binding of E2020 to AChE and BChE. This is due...
