We present two regression models for the prediction of pairwise preference judgments among MT hypotheses. Both models are based on feature sets that are motivated by textual entailment and incorporate lexical similarity as well as local syntactic features and specific semantic phenomena. One model predicts absolute scores; the other one direct pairwise judgments. We find that both models are co...

The Recognizing Textual Entailment System shown here is based on the use of a broad-coverage parser to extract dependency relationships; in addition, WordNet relations are used to recognize entailment at the lexical level. The work investigates whether the mapping of dependency trees from text and hypothesis give better evidence of entailment than the matching of plain text alone. While the use...

While a significant amount of research has been devoted to textual entailment, automated entailment from conversational scripts has received less attention. To address this limitation, this paper investigates the problem of conversation entailment: automated inference of hypotheses from conversation scripts. We examine two levels of semantic representations: a basic representation based on synt...

Synthetic m ethodologies for the preparation of nitroxyl labeled derivatives of D-( + )-glucose, a-D -( + )-m ethylglycoside, 2-am ino-2-deoxy-D-( + )-glucose, and D-( + )-glucuronic acid are pre­ sented. The spin labels in these compounds are attached variably at the 1, 2, 3, and 6 positions of the glucose framework. These new com pounds, being water soluble and producing marked en­ hancement ...
