Re: [Dbpedia-dutch] [Dbpedia-discussion] gender extraction from Wikipedia

[Pablo N. M. <pab...@gm...>]

Hi Ruben,
Do you think this could improve on the current Gender extractor that Max
and I created? We'd love to have it improved. Why don't you send a pull
request over there?

https://github.com/dbpedia/extraction-framework/blob/master/core/src/main/scala/org/dbpedia/extraction/mappings/GenderExtractor.scala

I also like your idea to use this for anomaly detection. I wonder if we
already have a way to output suggested "negative triples" in a standard
fashion for the DEF? Meaning that we could have a bunch of "negative
extractors" suggesting which triples should be deleted. I think Heiko and
Dimitris have played with ideas related to this?

Cheers
Pablo
