Centering theory is the best-known framework for theorizing about local coherence and salience; however, its claims are articulated in terms of notions which are only partially specified, such as " utterance, " " realization, " or " ranking. " A great deal of research has attempted to arrive at more detailed specifications of these parameters of the theory;(More)
SpatialML is an annotation scheme for marking up references to places in natural language. It covers both named and nominal references to places, grounding them where possible with geo-coordinates, including both relative and absolute locations, and characterizes relationships among places in terms of a region calculus. A freely available annotation editor(More)
We use machine learning techniques to find the best combination of local focus and lexical distance features for identifying the anchor of mereological bridging references. We find that using first mention , utterance distance, and lexical distance computed using either Google or WordNet results in an accuracy significantly higher than obtained in previous(More)
SpatialML is an annotation scheme for marking up references to places in natural language. It covers both named and nominal references to places, grounding them where possible with geo-coordinates, and characterizes relationships among places in terms of a region calculus. A freely available annotation editor has been developed for SpatialML, along with(More)
The definitions of the basic concepts, rules, and constraints of centering theory involve underspecified notions such as 'previous utterance', 'realization', and 'ranking'. We attempted to find the best way of defining each such notion among those that can be annotated reliably , and using a corpus of texts in two domains of practical interest. Our main(More)
The aim of this article is to introduce a treatment of the prepositions heading temporal adverbials as binary operators which select for certain aspectual properties of their arguments and order these arguments temporally. I extend the Dowty 1986]/Taylor 1977] characterization of the aspectual classes to include certain basic properties of events and argue(More)
