... usually proceed in two steps and we adopt this approach. 1. Hypothesis Generation: Identify all SCCs from the corpus data. 2. Hypothesis Selection: Determine which SCC is a valid SCF for a particular ... cues. Our evalu- ator has two parts: the Binomial Hypothesis Test (Brent, 1993) and a back-off algorithm (Sarkar and Zeman, 2000). 1. The Binomial Hypothesis Test (BHT): Let p be the probabil...

... actions in this tree. Problems arise, and the EDOL hypothesis is violated, when there is a dependence between different parser actions. The EDOL hypothesis states that elementary trees provide a ... and parsing (Joshi and Srinivas, 1994; Evans and Weir, 1998). On the other hand, if the EDOL hypothesis holds for those dependencies that are being checked by the parser, then the burden...

... trivial partial dependency tree con- sisting of a single node w h and no links. This same set of hypotheses can be used for all the parsers, so we do not make it explicit for subse- quent schemata. ... each of the items corresponding to the subtrees induced by the direct dependents, and to the hy- pothesis [h, h, h, , ]. This allows us to infer p items representing the result of linking eac...

In order to test this hypothesis, we con- ducted an experiment with BitPar ... treated as a fronted subordinate clause. 4 Experiment 1: n-Best Parsing and Reranking The first hypothesis for improving coordination parsing is based on the assumption that the correct parse m...
