The transliteration model is a joint source channel model (Li et ... labelled information for training. Our sys- tem extracts transliteration pairs in an unsupervised fashion. It is also able to utilize labelled information if available, obtaining improv...

... different qualities. For example, both topic “css test” and “test suite” are the bi-gram matching for query “css test suite”; however, the former might be more informative. To model that, we use ... following sub-sections, we will detail two sub-models: the expert matching model P(c|e) and the evidence matching model P(e|q). 3.2 Expert Matching Model We expand the evidence...

... use a nearly identical model to the FLAT model, but instead of having a single m variable, we have three: one for IE, one for Austronesian and one for “all languages.” For a general tree, we ... in Figure 3 (on a log-scale for the x-axis). The two best-performing models are the two hier- archical models. The flat model does significantly worse and the random model does terribly...

... predicates like force generally introduce E-type SEs: (7) I forced [John to run the race with me]. (8) * I forced [John to know French]. The feature force-PREV is extracted if a member of the force-type ... non-absolute, making them inappropriate for a rule-based model. Our models handle the defeasibility of these correlations probabilistically, as is standard for machine learning for...
