Listing common misevaluations

[ploo...@gmail.com]

Hi again

I think I may have a suggestion you guys could have already come up with.

While you review the users' evaluations I'm pretty sure there can be a number of patterns emerging where users mark some triples as errorneous but in fact these are not.

For example I have a number of times come accross triple like

dbpedia:something dbprop:yearFounded "2000"^^xsd:integer

Instinctively it seems not right since there is the xsd:Year datatype. However I wasn't really sure whether it actually is an error or maybe this is the intended way it should have been extracted. Thus a set of examples of what people can encouter and some guidelines how to react in common cases could be good and also spare some of your time.

Regards,
Tom

Yes, we do intend to check the evaluations to ensure they are in fact errors and also to find out the root cause problem. 

For example I have a number of times come accross triple like

dbpedia:something dbprop:yearFounded "2000"^^xsd:integer

Instinctively it seems not right since there is the xsd:Year datatype. However I wasn't really sure whether it actually is an error or maybe this is the intended way it should have been extracted.

It does seems like a datatype error where it should have been year. In general, we have noticed that the most errors lie in the values associated to the dbpprop property. 

 

Thus a set of examples of what people can encouter and some guidelines how to react in common cases could be good and also spare some of your time.

The reason we are doing this campaign is to find such common errors. Although we have found a number of them (as listed in the tree of errors), we hope that others can find other types of errors too. In fact each error type has an associated example and a description so as to help people correctly evaluate similar problems.

Hope that helps !

Thanks.

Regards,
Tom
