--------------------
The 2016 ENtity Summarization Evaluation Campaign (ENSEC 2016)
co-located with the SumPre 2016 workshop


http://km.aifb.kit.edu/ws/sumpre2016/challenge.html


The volume of entity-centric data is rapidly increasing on the Web, including 
RDF and Linked Data, Schema.org, Facebook’s Open Graph, and Google’s Knowledge 
Graph, describing entities (e.g., directors and films) and relations between 
them (e.g., directs). The description of an entity, consisting of a set of 
entity-property-value triples, is sometimes too long to be entirely presented 
to a user. As a substitute, a compact summary can be shown to help the user 
efficiently while effectively perform a task (e.g., browsing, searching).


Specifically, an entity summary is a subset of entity-property-value triples 
selected from the description of an entity. Entity summarization is the task of 
automatically generating a high-quality entity summary, to be used for a 
specific task or for general purposes. Whereas several preliminary solutions 
have been proposed [1][2][3], the problem is still far from being solved. 
Therefore, this ENtity Summarization Evaluation Campaign (ENSEC) is organized 
to assess strengths and weaknesses of entity summarization systems, compare 
performance of techniques, and enhance communication among researchers and 
developers.


ENSEC-2016, co-located with the SumPre 2016 workshop, consists of two tracks: 
the DBpedia-50 track and the LinkedMDB-30 track. A system can participate 
either or both tracks, by submitting summaries it generates for a set of 
specified entities. The results will be evaluated against gold-standard entity 
summaries given by human experts.


Winners and runner-ups will share Amazon vouchers in a total value of 350 
Euros, sponsored by the SumOn project.
