MARVIN-config

MARVIN is the release bot that does automated DBpedia releases each month on three different servers for generic, mappings, wikidata, abstract extraction. The repository at https://git.informatik.uni-leipzig.de/dbpedia-assoc/marvin-config can be used to fork the architecture for creating extensions, developing new extractors or debugging old ones. Fixes and patches will be manually deployed via a fresh git clone from the master branch of the DIEF (DBpedia Information Extraction Framework).

Contributions & License

All scripts and config files in this repo are CC-0 (Public Domain). We accept pull requests to improve the config files, all contributions will be merged as CC-0.

Run a MARVIN extraction

git clone https://git.informatik.uni-leipzig.de/dbpedia-assoc/marvin-config
cd marvin-config
# delete previous versions of the DIEF
rm -rf marvin-config/extraction-framework
./setup-dief.sh
# test Romanian extraction, very small
./marvin_extraction_run.sh --group=test

To run the other extractions, use either

# around 4-7 days
./marvin_extraction_run.sh --group=generic
# around 4-7 days
./marvin_extraction_run.sh --group=mappings
# around 7-14 days
./marvin_extraction_run.sh --group=wikidata

Cronjobs

Below is a list of cronjobs we use on the different servers

Acknowledgements

We thank Sören Auer and the Technische Informationsbibliothek (TIB) for providing three servers to run:

  • the main DBpedia extraction on a monthly basis
  • community-provided extractors on Wikipedia, Wikidata or other sources
  • enrichment, cleaning and parsing services, so-called Databus mods for open data on the Databus

This contribution by TIB to DBpedia & its community is a great push towards incentivizing Open Data and establishing a global and national research and innovation data infrastructure.

Update and Run the extraction

Deploy MARVIN on Databus

TODO

[Manual] Run Databus-Derive (clone and parse)

On the respective server there is a user marvin-fetch, that has access to /data/derive containing the pom.xml of https://github.com/dbpedia/databus-maven-plugin/tree/master/dbpedia

# query to get all versions fro derive in xml syntax to paste directly into pom.xml
PREFIX dataid: <http://dataid.dbpedia.org/ns/core#>
SELECT distinct (?derive) WHERE {

    ?dataset dataid:group <https://databus.dbpedia.org/marvin/generic> .
    ?dataset dataid:artifact ?artifact .
    ?dataset dataid:version ?version .
    ?dataset dct:hasVersion "2019.08.30"^^xsd:string
	BIND (CONCAT("<version>",?artifact,"/${databus.deriveversion}</version>") as ?derive)
}
order by asc(?derive)

su marvin-fetch
tmux a -t derive

# prepare
cd /data/derive/databus-maven-plugin/dbpedia/$WHAT
git pull
mvn versions:set -DnewVersion=$NEWVERSION
# run
mvn databus-derive:clone -Ddatabus.deriveversion=$NEWVERSION

[Manual] pull data to downloads.dbpedia.org server

run marvin-fetch.sh script in databus/dbpedia folder

cd /media/bigone/25TB/releases/databus-maven-plugin/dbpedia
./marvin-fetch.sh wikidata 2019.08.01

Deploy cleaned files to dbpedia

cd /media/bigone/25TB/releases/databus-maven-plugin/dbpedia/mappings
mvn clean
