TimeML: Robust Specification of Event and Temporal Expressions in Text
James Pustejovsky,José M. Castaño,Robert Ingria,Roser Saurí,Robert Gaizauskas,Andrea Setzer,Graham Katz,Dragomir R. Radev +7 more
TL;DR: TimeML is described, a rich specification language for event and temporal expressions in natural language text, developed in the context of the AQUAINT program on Question Answering Systems, and demonstrated for a delayed (underspecified) interpretation of partially determined temporal expressions.

SemEval-2007 Task 15: TempEval Temporal Relation Identification
TL;DR: The TempEval task proposes a simple way to evaluate automatic extraction of temporal relations by defining three sub tasks that allow pairwise evaluation of temporal Relations.
The Specification Language TimeML.
James Pustejovsky,Robert Ingria,Roser Saurí,José M. Castaño,Jessica Littman,Robert Gaizauskas,Andrea Setzer,Graham Katz,Inderjeet Mani +8 more
TL;DR: This paper provides a description of TimeML, a rich specification language for event and temporal expressions in natural language text, developed in the context of the AQUAINT program on Question Answering Systems, and demonstrates the expressiveness of timeML for a broad range of syntactic and semantic contexts.

Automatic Identification of Non-Compositional Multi-Word Expressions using Latent Semantic Analysis
Graham Katz,Eugenie Giesbrecht +1 more
TL;DR: It is proposed that vector-similarity between distribution vectors associated with an MWE as a whole and those associated with its constituent parts can serve as a good measure of the degree to which the MWE is compositional.

05151 Summary—Annotating, Extracting and Reasoning about Time and Events
TL;DR: The main focus of the seminar was on TimeML-based temporal annotation and reasoning as discussed by the authors, with three main points: determining how effectively one can use the TimeML language for consistent annotation, determining how useful such annotation is for further processing, and determining what modifications should be applied to the standard to improve its usefulness in applications such as question-answering and information retrieval.
