... annotators may be paid for the number of an- notations they produce or by the hour. In the context of parse tree annotation, Hwa (2004) estimates cost using the number of constituents needing labeling and ... corpus. Hence, there is strong motivation to reduce annotation costs, but not at the expense of quality. Active learning (AL) can be employed to reduce the costs o...

... conserved CXXXC motif. A possible explanation of this result is that the soaking solution contained Cu(II) rather than Cu(I) ions, and the Cu(II) ions could then have catalysed oxidation of the conserved ... [17]. The thiol-disulfide oxidoreductase function of the CXXXC motif of human Sco proteins could therefore be impli- cated not only in the maturation of the Cu A si...
