Dear DBpedians,
We are happy to announce that Markus Freudenberg and Dimitris Kontokostas
from the University of Leipzig are already working on the next DBpedia
Release.
As with the previous releases, it is planned that all extractors for all
languages will be run. The resulting dumps will be provided for download
via the DBpedia download page (as it is for
http://wiki.dbpedia.org/Downloads) and will be loaded into the public
DBpedia SPARQL endpoint. We hope to be able to publish the new release at
the end of April.
As a lot of additional infobox-to-ontology mappings for various languages
have already been entered by the mapping editors community into the DBpedia
Mapping Wiki (http://mappings.dbpedia.org/
<http://mappings.dbpedia.org/index.php/Main_Page>) since the last DBpedia
release, we hope to be able to provide clean data for even more infoboxes
in even more languages with the new release.
With this email, we would also like to ask all members of the mapping
editors community for their help with the upcoming DBpedia release in the
form of a *MappingSprint*:
1. Could you please check whether the mappings that you have entered into
the wiki over the last year still work correctly?
2. If you still want to refine and extend mappings and/or the ontology, now
would be the perfect time to do so.
3. In order to help increasing the infobox coverage of the new release, it
would also be great if you map additional templates or additional
properties of existing templates to the ontology.
Also note that now we have separate issue trackers for the mappings and the
ontology where we discuss design issues
https://github.com/dbpedia/ontology-tracker/issues
https://github.com/dbpedia/mappings-tracker/issues
For helping you see which widely used templates still require additional
property mappings, we have updated the Mapping Wiki statistics for all
languages:
http://mappings.dbpedia.org/server/statistics/
Further functionality for testing and exploring the current mappings is
available at:
http://mappings.dbpedia.org/server/
For the English Wikipedia edition, you can see for instance at
http://mappings.dbpedia.org/server/statistics/en/?show=100
that there is still room for improving the mappings.
The statistics for German, Spanish and French are found below and also
still show lots of gaps for these important languages:
http://mappings.dbpedia.org/server/statistics/de/?show=100
http://mappings.dbpedia.org/server/statistics/es/?show=100
http://mappings.dbpedia.org/server/statistics/fr/?show=100
You also have a possibility to see the list of errors for the current
mappings, for instance for French you can validate either a specific
mapping or all mappings at once
http://mappings.dbpedia.org/server/mappings/fr/
http://mappings.dbpedia.org/server/mappings/fr/validate/* - error list for
all French mappings
If you want to to refine and extend the ontology, note that you can add
links between the DBpedia ontology and other schemata/ontologies, e.g. to
schema.org or Wikidata as in the example below
http://mappings.dbpedia.org/index.php/OntologyProperty:Author
We will use all mappings that are entered into the Mapping Wiki until
*March 31st* for the upcoming DBpedia release.
It would thus be great if as many editors as possible participate in the
mapping sprint and we as a community try to increase the mapping coverage
as far as possible until this date.
Lots of thanks already in advance to all mapping editors who participate.
Let's all try to make the next DBpedia release even better!
Cheers,
Markus Freudenberg, Dimitris Kontokostas, Sebastian Hellmann
