The Linked Data for Information Extraction challenge explores how 
structured data on web pages can be used to train information extraction 
systems extracting that information from other sources as well. It is 
based on a subset of the Web Data Commons Microformats dataset [1].

For the challenge, original annotated pages are provided, as well as the 
triples extracted from them. Based on that information, participants 
have to design an information extraction system for extracting that 
information from other web pages. In this year's challenge, we focus on 
hCard data [2], i.e., information about persons. The use case of such a 
system could be the assembly of a large database on person data.

The systems are evaluated on a test set of annotated web pages, from 
which all annotations have been removed. The participants have to 
extract triples from those pages and send in their resulting triple 
files. The submitted files are evaluated against the gold standard of 
the original triples, ranking the solutions by F-measure.

A short description of each solution is included in the LD4IE workshop 
proceedings, and presented at the workshop [3].
