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

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

= 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.
