... Sentences that are too complex are hard to understand, so are sentences lacking seman- tic cohesion and cross -sentence coherence. Further more, bad sentence boundary decisions may even make sentences ... novel instance- based sentence boundary determination method for natural language generation that optimizes a set of criteria based on examples in a corpus. Compared to exist- ing...

... receives an input sentence x = w 1 , w 2 , . . . , w n and computes a dependency graph G = (W, A). The set of nodes W = {w 0 , w 1 , . . . , w n } corresponds to the words of a sentence, and the ... parser that considers more global dependency relations. 3 Tree -Based Parsing Applied to Nivre’s Method 3.1 Overall Procedure Tree -based parsing uses trees as the procedural el- ements inste...

... two related sentences, outputs a single sentence expressing the information shared by the two input sentences (Barzilay and McKeown 2005). Consider, for example, the following pair of sentences: 1 (1) ... various pairs of related sentences, both generic and question -based ones, and both intersection and union ones. While it seems a reasonable hypothesis that question -based fusions will...
