... Association for Computational Linguistics A Maximum Expected Utility Framework for Binary Sequence Labeling Martin Jansche ∗ jansche@acm.org Abstract We consider the problem of predictive infer- ence for ... Notation We formulate our approach in terms of sequence la- beling, although it has applications beyond that. This is motivated by the fact that our framework for...

... under the framework of convo- lution tree kernel for SRL. In this paper, we fol- low the same framework and design a novel hybrid convolution kernel for SRL. 3 Feature-based methods for SRL Usually ... con- volution kernels for a discrete structure. In the context of convolution kernels, more and more kernels for restricted syntaxes or specific do- mains, such as string kernel f...

... There- fore, these results clearly indicate that the electron transport system for CYP175A1 is composed of Fdx, FNR, and NADPH (Fig. 4B). All quantitative analyses were performed at 65 °C for 2 ... via OFOR and Fdx to CYP119 [13,14]. Inter- estingly, the electron transport system for CYP175A1 did not utilize OFOR, although the T. thermophilus HB27 genome contains the genes encoding OFOR...

... the left-right dual of a left- corner transform. It transforms all right recursive sequences in each tree into left recursive sequences of symbols of the form A 1 /A 2 , denoting an incom- plete ... Right-corner transform Binarized trees 2 are then transformed into right- corner trees using transform rules similar to those described by Johnson(1998a). This right-corner transform is simply the...

The “Direction” tag gives information about whether to take the head-node of ... case of binary reduc- tion. A simple transformation process as described in (Sagae and Lavie, 2005) is employed to con- vert between arbitrary branching trees and binary trees. This...

For example, the lingoes “duno”, “ysnite” have to be normalized using an insertion trans- formation to become ... of 2300 transforma- tions. Substitution accounts for almost 86% of all transformations. Deletion and substitution make up the rest. Table 3 shows the top 10 most com- mon transformatio...
