Hi dbpedia--
Thanks for outstanding work. I'm new here. I wanted to flag/ask
about a potential parse error in a species infobox. I haven't
investigated to see how widespread it might but, but happened across
this one and wanted to inquire about it.
I noticed that the phylum of Longjaw Mudsucker appears to differ from
current and historical versions of the scientific classification
infobox for the species.
In the English Wikipedia page for Longjaw mudsucker, the scientific
classification infobox in the current version appears as follows:
Longjaw mudsucker
Scientific classification
<http://en.wikipedia.org/wiki/Biological_classification>
Kingdom: Animalia <http://en.wikipedia.org/wiki/Animal>
Phylum: Chordata <http://en.wikipedia.org/wiki/Cordate>
Class: Actinopterygii <http://en.wikipedia.org/wiki/Actinopterygii>
Order: Perciformes <http://en.wikipedia.org/wiki/Perciformes>
Family: Gobiidae <http://en.wikipedia.org/wiki/Goby>
Genus: /Gillichthys <http://en.wikipedia.org/wiki/Gillichthys>/
Species: /*G. mirabilis*/
In contrast the dbpedia resource for Longjaw_mudsucker lists:
ontology/kingdom: Animal
ontology/phylum: leaf_shape (??)
ontology/class: Actinopterygii
ontology/order: Perciformes
ontology/family: Goby
ontology/genus: Mudsucker
For many of those, my naive read is consistent with a standardized
ontology of kingdoms, phylums, etc (though I am not sure about what is
actually happening, I am guessing the parser is translating Gobiidae
to Goby or Animalia to Animal based on a set of rules).
If you check the source of the article at [1], you will find that the
value for "Family" looks like
familia = [[Goby|Gobiidae]]
which means that the first value is the title of the Wikipedia article
to which this link refers, whereas the other value is its label, i.e.
the one that should appear to viewer of the article.
This also applies for "Phylum".
I do not understand why the phylum would be listed as "Leaf Shape"
however. Any ideas?
I'm really not sure about the reason of such strange behavior.
And also if you try the following query, in order to get all resources
whose phylum is "Leaf_Shape":
select ?s where {?s dbpedia-owl:phylum dbpedia:Leaf_shape}
you would get dbpedia:Longjaw_mudsucker only.
Anyway, that error is corrected in DBpedia-Live available at [2], and
there you can get the correct values.
James
Hope that helps.
