UK idavy@weather3000.com Abstract We describe our initial investigations into generating textual summaries of spatio- temporal data with the help of a prototype Natural Language Generation (NLG) system that produces pollen ... devices such as remote sensing sys- tems are generating vast amounts of spatio -temporal data. These devices, coupled with the wider accessi- bility of the data,...

We show how we can employ this crucial input to extract and train a hierarchical translation struct...

University {mgalley,jurafsky,manning}@stanford.edu Abstract Existing evaluation metrics for machine translation lack crucial robustness: their correlations with hu- man quality judgments vary considerably across lan- guages and genres. We believe ... which always correlates well with human judgments. Our paper proposes two strategies. We first ex- plore the combination of traditional score...

Figure 1: Example of speech translation output enriched with dialog act The remainder of this paper is organized ... Introduction Recent approaches to statistical speech translation have relied on improving translation quality with the use of phrase translation (Och and Ney, 2003; Koehn, 2004). The qualit...

All these relations are intended as ... via backward-presupposition as it temporally follows and presupposes play. Finally, in causation the entailing verb v t necessarily causes v h . In this case, the temporal relation is thus...
