1. Workshop Description

The computational analysis of time is a challenging and very topical 
problem, as the needs of applications based on information extraction 
techniques expand to include varying degrees of time stamping and 
temporal ordering of events and/or relations within a narrative. The 
challenges derive from the combined requirements of a mapping process 
(text to a rich representation of temporal entities), representational 
framework (ontologically-grounded temporal graph), and reasoning 
capability (combining common-sense inference with temporal axioms).

Usually contextualized in question-answering applications (with obvious 
dependencies of answers on time), temporal awareness directly impacts 
numerous areas of NLP and AI: text summarization over events and their 
participants; making inferences from events in a text; overlaying 
timelines on document collections; commonsense reasoning in narrative 
and story understanding.

Interest in temporal analysis and event-based reasoning has spawned a 
number of important meetings, particularly as applied to IE and QA tasks 
(cf. at COLING 2000; ACL 2001; LREC 2002; TERQAS 2002; TANGO 2003, 
Dagstuhl 2005). Significant progress has been made in these meetings, 
leading to developing a standard for a specification language for events 
and temporal expressions and their orderings (TimeML).  While recent 
research in the broader community (as indicated, for instance, in the 
most recent symposium on Annotating and Reasoning about Time and Events) 
highlights TimeML's status as an interchange format, this workshop, 
however, is not intended to focus on TimeML exclusively.  Likewise, 
while the ultimate goal of temporal analysis is to facilitate reasoning 
about time and events, the formal aspects of this problem are being 
addressed by other meetings (see, for instance, the TIME 2006 
Symposium).  Instead, the workshop will explore largely the linguistic 
implications for temporal-analytical frameworks.

The goal of the meeting, therefore, is to address issues already raised, 
but not fully explored---including but not limited to the following:

= infrastructure questions: temporal annotation methodology, tools; 
reliable measures of inter-annotator agreement; community resources.

= analytical frameworks: temporal information extraction; approaches to 
temporal expression normalization; relationship between named entity 
recognition and temporal entities analysis; dependency (or not) upon 
syntactic and discourse structure.

= mapping to time ontology(ies): completeness of the representation 
framework; formalization of the process; additional temporal reasoning 
capabilities required.

= reasoning over time: in particular, (robust) reasoning within 
representational schemes demonstrably derivable with current 
IE/analytical frameworks.

= applications of temporal analytics and reasoning: in addition to NL 
tasks, of particular interest are studies of temporal information as it 
manifests in, and impacts, different domains: beyond news, time is 
intrinsically essential in eg. legal, health-care, intelligence, 
financial contexts.

= national language: relationship between language characteristics and 
representational frameworks; generalizations of temporal analytics 
across multiple languages; multi-/cross-lingual resource development.


2. Target Audience and Participants

This workshop will be of interest to those creating or exploiting 
temporally annotated corpora; those developing information extraction, 
question answering, and summarization systems relying on temporal and 
event ordering information; researchers involved in creating chronicles 
and timelines from textual data (legal, health-care, intelligence); 
semantic web designers and developers wanting to link web ontologies and 
standards to temporal markup from natural language; researchers 
interested in temporal properties of discourse and narrative structure; 
and those interested in annotation environments and development tools.
