Opening presentation of the DeRiVE workshop at ISWC 2011, October, Bonn, Germany

1. 1st WORKSHOP ON DETECTION,
REPRESENTATION AND
EXPLOITATION OF EVENTS
Marieke van Erp, Anthony Jameson and Raphaël Troncy
Willem Robert van Hage and Laura Hollink
23/10/2011 - 1st Workshop on Detection, Representation and Exploitation of Events - Bonn, Germany -1

2. Workshop Goals
 Bring together researchers working on event
detection, representation, and exploitation
 Set some baselines for event detection,
representation, exploitation
 Collaboratively discuss:
 Twitter conversation: #derive2011
 http://titanpad.com/derive2011/
 Have a good time

 An Event-Based Approach to Describing and Understanding
Museum Narratives Paul Mulholland, Annika Wolff, Trevor Collins,
Zdenek Zdrahal
 Publishing, Linking and Annotating Events via Interactive Timelines:
an Earth Sciences Case Study Lianli Gao and Jane Hunter

 Discussion

4. How can events be modeled and
represented in the semantic web?
 How can we improve the interoperability of the various
event vocabularies such as EVENT, LODE, SEM,
EventsML, and F?
 How can aspects of existing event representations
developed in other communities be adapted to the needs
of the semantic web?
 What are the requirements for event representations for
qualitatively different types of events (e.g. historical
events such as wars; cultural events such as upcoming
concerts; personal events such as family vacations)?
 To what extent can/should a unified event model be
employed for such different types of events?

5. Programme (2)
 Session 2: Event Detection (11:00-12:30)
 Using Semantic Role Labeling to Extract Events from Wikipedia
Peter Exner, Pierre Nugues
 An Overview of Event Extraction from Text Frederik Hogenboom,
Flavius Frasincar, Uzay Kaymak, Franciska de Jong
 Crowdsourcing Event Detection in YouTube Videos Thomas Steiner,
Ruben Verborgh, Michael Hausenblas
 Clues of Personal Events in Online Photo Sharing Pierre Andrews,

 Discussion

6. How can events be detected and extracted
for the semantic web?
 How can events be recognized in particular types of
material on the web, such as calendars of public events,
social networks, micro blogging sites, semantic wikis,
and normal web pages?
 How can the quality and veracity of the events
mentioned in noisy micro blogging sites such as Twitter
be verified?
 How can a system recognize when a newly detected
event is the same as a previously detected and
represented event?
 How can a system recognize a complex event that
comprises separately recognizable sub-events?

 Discussion

8. How can events be exploited for the
provision of new or improved services?
 How can event representations be better exploited in
support of activities like semantic annotation, semantic
search, and semantically enhanced browsing?
 What application areas for semantic technologies can
benefit from an increased use of event representations?
 How can we improve existing methods for visualizing
event representations and enabling users to interact with
them in semantic web user interfaces?
 What requirements for event detection and
representation methods are implied by advances in
methods for exploiting events?
