... similar to the expanded set recently used for Hiero (Chiang et al., 2009), but with bigram features (source and target word) instead of trigram features (source and target word and neighboring source ... translation. The decoder has to store in each hypothesis the source and target root labels of the partial derivation, but these la- bels are used for calculating fea...

... weight vector w, takes in a foreign sen- tence f and returns a translated hypothesis h. The argmax operates in vector space and our goal is to find w leading to hypotheses on the Pareto Frontier. In ... approach to optimiza- tion: i.e. optimizing towards points on the Frontier and away from those that are not, and giving no pref- erence to different pareto-optimal hypotheses. 2...

The annotators’ task was to indicate the locations of accents and/ or breaks that ... occurs in, with n ranging from 1 to 25, and computed in an iterative growth procedure: log- likelihoods of n + 1-grams were computed by ex- panding all stored n-grams one word to the...

Then the reduced context vectors were grouped into a pre-defined number of clusters whose centroids corresponded to senses of target word. Some ... contextual word’s vectors together may result in noise-dominated second or- der context vectors. To deal with this problem, we extend the feature selection procedure further to...
