1st Call for Papers SEMSEARCH'09 
Semantic Search 2009 Workshop 
Located at the 18th Int. World Wide Web Conference WWW2009 
April 21, 2009, Madrid, Spain 
http://km.aifb.uni-karlsruhe.de/ws/semsearch09 
Submission deadline for full papers: March 1st, 2009 (12.00 AM, GMT) 
=================================== 
In recent years we have witnessed tremendous interest and substantial 
economic exploitation of search technologies, both at web and 
enterprise scale. However, the representation of user queries and 
resource content in existing search appliances is still almost 
exclusively achieved by simple syntax-based descriptions of the 
resource content and the information need such as in the predominant 
keyword-centric paradigm (i.e. keyword queries matched against bag of 
words document representation). 
On the other hand, recent advances in the field of semantic 
technologies have resulted in tools and standards that allow for the 
articulation of domain knowledge in a formal manner at a high level of 
expressivity. At the same time, semantic repositories and reasoning 
engines have only now advanced to a state where querying and 
processing of this knowledge can scale to realistic IR scenarios. 
In parallel to these developments, in the past years we have also seen 
the emergence of important results in adapting ideas from IR to the 
problem of search in RDF/OWL data, folksonomies, microformat 
collections or semantically tagged natural text. Common to these 
scenarios is that the search is focused not on a document collection, 
but on metadata (which may be possibly linked to or embedded in 
textual information). Search and ranking in metadata stores is another 
key topic addressed by the workshop. 
As such, semantic technologies are now in a state to provide 
significant contributions to IR problems. 
In this context, several challenges arise for Semantic Search systems. 
These include, among others: 
* How can semantic technologies be exploited to capture the 
information need of the user? 
* How can the information need of the user be translated to expressive 
formal queries without enforcing the user to be capable of handling 
the difficult query syntax? 
* How can expressive resource descriptions be extracted (acquired) 
from documents (users)? 
* How can expressive resource descriptions be stored and queried 
efficiently on a large scale? 
* How can vague information needs and incomplete resource descriptions 
be handled? 
* How can semantic search systems be evaluated and compared with 
standard IR systems?
