DEADLINE EXTENSION: to MARCH 6
--- Final Call for Papers ---
4th Workshop on EVENTS will be held at the NAACH HLT 2016 conference in San Diego, California June 16 or 17, 2016.
It follows three prior successful and fun workshops at the NAACL 2013,ACL 2014, and NAACL 2015 conferences.
Proper understanding of the events of a text is increasingly important in NLP. The 4th Workshop on Events seeks to bring together researchers focusing on events with a variety of perspectives. This iteration of the Events workshop will center around two panels aimed at highlighting these differences:
Panel on the challenges of detecting and modeling events
- Eduard Hovy (CMU)
- Dan Roth (UIUC)
Panel on the relationship between events and ontologies
- Colin Baker (Berkeley)
- Sergei Nirenburg (RPI)
-- Background ---
Event definition and detection has a number of large divisions, largely due to differences in which events are annotated. Many annotations only consider events within a particular domain or ontology, as in LDC’s ACE and Machine Reading event annotation, or define other conditions (such as only looking at realis events). We hope to foster conversation between those dealing with "all events" approaches (where event detection has approached human performance in the recent Clinical Tempeval evaluations (Bethard et al. 2015)) and those dealing with added constraints added by specific ontologies or domains.
Dramatic strides have been taken in event coreference. Event coreference has been driven by the event coreference annotations of ACE and Ontonotes, and the cross-document annotations of the ECB (Bejan and Harabagiu (2010, extended by Lee et al. (2012) and Agata and Vossen (2014) ), but large questions remain, particularly with regard to how complicated phenomena related to coreference should be treated, such as bridging anaphora and subevent relationships between events (Poesio and Artstein 2005; 2008, Recasens et al. 2011, Araki et al. 2014).
Similarly, the relationships between events (as with temporal or causal relations), and the relationships between events and larger structures (such as scripts, timelines, or larger events) are important factors in event understanding. TimeML (Pustejovsky, et. al., 2010), or temporal relation annotation, has held numerous Semeval tasks regarding detection of temporal relations. Other relations between events, such as causation (Bethard and Martin 2008; Mizra et al. 2014) or contradiction detection (De Marneffe et al. 2008), have been studied. However, outside of temporal relations there is a paucity of consensus regarding what one's inventory of relations should be, and a lack of shared evaluations regarding them.
This workshop will be an active, discussion-driven workshop, with sessions devoted to particular issues and a poster session for accepted papers. One session will be devoted to discussion of the shared annotation task (below).
--- Topics seen in prior Events workshops ---
- Event coreference resolution or annotation
- Detecting relations between events (causation; opposition; temporal order,
etc.)
- Event detection
- Event ordering and clustering
- Annotation of corpora with events
- Usage of events detection or event coreference for other tasks
- Frames and Script induction
--- Submission Information ---
All submissions should follow the two-column format of the NAACL-HLT 2016 proceedings. Please use ACL’s LaTeX style files or Microsoft Word style files tailored for this year’s conference (available from the NAACL-HLT 2016 website). Submissions must conform to the official style guidelines, which are contained in the style files, and they must be electronic in PDF format. Papers that do not conform to these requirements will be rejected without review. Previously published papers cannot be accepted. The papers will be presented either orally or as posters.
We accept the following two kinds of submissions:
- Long Papers up to 8 pages, with up to 2 additional pages for references
- Short Papers up to 4 pages, with up to 2 additional pages for references
Submission dates are:
- March 6 2016: Workshop Paper Due Date
- March 25 2016: Notification of Acceptance
- April 7 2016: Camera-ready papers due
- June 17, 2016: Workshop
--- Shared Annotation ---
This Events Workshop will also involve a shared annotation task. A small set of documents (some of which may deal with the same real-world event) will be released, and participants will invited to provide annotations of these documents. A basic set of event annotations will be provided (using Richer Event Description guidelines), to enable participants to focus on particular relations or features of interest. A session of the workshop will focus on the various annotations provided.
