    CFP: Data In Web Search (DISH) Workshop - 13th May 2013, Rio de Janeiro, Brazil.      

    Workshop: <> 
    Conference: <>

    This WWW2013 Workshop focuses on new approaches to using structured  
    data for improving Web search. Most Web documents and queries are  
    about entities and the relationships between them, i.e., structured  
    data with documented semantics. However, popular search engines    
    have historically ignored structured data, instead relying on 
    techniques that model the document and queries as a bag of  

    Recent developments, most notably the dramatic increase in  
    the use of structured data markup on web pages have lead to   
    substantial interest from mainstream search engines. However, we are 
    still in the very early stages in the evolution of how search 
    engines use this structured data. Most of the current work is 
    focussed on searching databases of facts about entities and   
    presenting them either alongside the search results, or on  
    annotating search results with additional data. The core problems of 
    utilizing knowledge about entities for improving the ranking of    
    documents, helping set the user context, etc. are still largely    
    unexplored territories.  
    While the use of structured data is still limited in Web    
    search engines, active research in this direction can be observed in 
    many communities. Most notably, there is a broad range of   
    solutions proposed by IR, database, and Semantic Web researchers for 
    exploiting structured data for various search tasks. The goal of   
    this Workshop is to bring these communities together to focus on the 
    central question of how to make these solutions applicable to Web  
    search engines. The central theme of the workshop is to explore new  
    and novel ways for exploiting explicit representations of entities   
    and the relationships between them to improve Web search.   

    Important Dates      

    Workshop proceedings will be published through the ACM Digital     
    Library, with associated tight production deadlines:   

    * February 23rd 2013: Workshop paper deadline    
    * March 13th 2013: Workshop paper notifications    
    * April 2nd 2013: Workshop paper final copy
    * WWW2013 Conference: May 13-17th 2013, Rio de Janeiro, Brazil   
    * Workshop day: May 13th 2013.     
    Three main directions of semantic search have emerged. The first is  
    the use of structured data to augment traditional web search results 
    and the search results page. The second is to use the structured   
    data to directly deliver results to search requests and to answer  
    questions. The third is to use knowledge about a domain to affect  
    ranking of results. This workshop targets all these directions of  
    semantic document retrieval and semantic data retrieval but puts   
    special emphasis on the web search context. Possible topics for    
    submission include, but are not limited to:   
     * Structured data for Web document retrieval     
     * Entity/relation aware document and query models  
     * Entity/relation aware matching and ranking     
     * Use of structured data for building vertical search engines    
     * Web data retrieval      
     * Searching structured data with textual queries   
     * Novel applications of structured data to augment search results  
     * Evaluation methodologies    
    Workshop papers should be submitted by Feb 23rd 2013 using EasyChair 
    (we are 'dish2013' there), see <> 
    The organizers can be contacted at 
    in case of technical issues with the submission process. Due to the tight schedule,     
    please don't ask for extensions!     
    We invite posters and papers of max. 6 pages presenting new ideas  
    for how structured data can be used in search, preferably with     
    working demos. Accepted papers will be published as part of the    
    International Conference Proceedings Series (ICPS) of the ACM 
    Digital Library.       
    We plan to accept 8-12 papers and organize a full day event, roughly 
    half devoted to each of the two approaches. Each session will have a 
    significant time set aside for discussion. There will also be a    
    poster session. Attendance will be open to the public (via WWW2013   
    Workshops registration <>). 
    We plan to have one or two invited talks.
