What we will cover

Ermilov et al. presented a wiki-based approach to crowd-sourcing the enhancements of ~9k datasets listed at http://publicdata.eu (WebSci 2012 paper).

A year after its publication, how far have the enhancements come?

This pages provides a summary and review of Ermilov's wiki.publicdata.eu CSV2RDF Application.

Let's get to it

How many people contributed to the "crowd-source" enhancement?

Four accounts contributed, and the two non-author accounts provided fewer than ten contributions.

find manual/pages -name "*.ttl" | xargs -L1 grep "wasAttributedTo" | sort -u shows only a handful of contributors:

      prov:wasAttributedTo <http://wiki.publicdata.eu/wiki/User:178.25.43.32>;
      prov:wasAttributedTo <http://wiki.publicdata.eu/wiki/User:2001:638:902:2010:0:168:35:101>;
      prov:wasAttributedTo <http://wiki.publicdata.eu/wiki/User:Iermilov>;
      prov:wasAttributedTo <http://wiki.publicdata.eu/wiki/User:IvanErmilov>;
      prov:wasAttributedTo <http://wiki.publicdata.eu/wiki/User:Soeren>;

How many existing vocabulary terms did the crowd-sourced enhancement produce?

Fifteen terms were reused from nine vocabularies for more than 9,000 datasets. We skip the three non-CURIEs listed below because it is not clear that they are RDF terms.

find manual/pages -name "*.xml.ttl" | xargs -L1 grep "conversion:label" | sed 's/conversion:label//' | grep : | sed 's/^ *"/"/' | grep -v " " | sort -u:
