New CI Tests on DBpedia Releases

Hi all,
we looked at the CI tests in the framework: https://github.com/dbpedia/extraction-framework/tree/master/core/src/main/scala/org/dbpedia

and since we do more frequent releases now at http://databus.dbpedia.org/marvin/ we devised a new testing methodology. that works on artifacts and S, P, O individually.
We published a draft vocabulary using triggers and validators for IRIs: https://github.com/dbpedia/extraction-framework/blob/master/new_release_based_ci_tests_draft.ttl

Coverage is defined as:
C_s := Subjects with at least one trigger / all subjects
C_p := same for predicate
C_o := same for objects
C_total = AVG (C_s, C_p, C_o)

So we can measure each part of the triples individually and more systematically.
The first test we will implement is:

v:doesNotContainCharacters "&" , " ", "?", "\"", "'" .
for dbpedia.org/resource IRIs

Hi, I wrote a first iri test prototype using apache spark and that is based on the earlier posted test case file.

It implements the regex based trigger functions and for the validators the v:regexPattern, v:doesDotContainChar statements are working. But v:basedOnVocab is still missing, so DBpedia ontology properties dont get validated/tested correctly.


Here are some first coverage results for selected artifacts of the mappings and wikidata group.

After testing i realised that for “trigger:wikidata_dbpedia_extraction” no validator was assigned.

Hi all,
CI Tests are working

Run on Minidump

git clone https://github.com/dbpedia/extraction-framework.git
cd dump
mvn test

Configure tests


currently is this here:
