Hi all,Currently we are developping an application based on DBPedia entities
and YAGO classes. The main source dataset is "Links to YAGO" on page
“http://wiki.dbpedia.org/Downloads36”from DBpedia3.6.
According to YAGO:"Conceptually, the hypernymy relation in WordNet spansa
directed acyclic graph (DAG) with a single root node called entity"
@NameOfTheOntology,Now considering the YAGO2 dataset for class hierarchy, is it
a reduced set(without dubpicated items:the third line) like the following
case?class1 subclass class3class2
subclass class3class1 subcalss class3
(can be deduced from the first 2 triples )
@dbpedia-dicussion, Regarding the two hypothesis(1.YAGO2 did provid reduced
dataset, 2.YAGO2 didn't ), would your extraction algorithm lead to the
following items in "Links to YAGO" dataset?entity1 type
leafClass1leafClass1 subclass upperClass1entity1
type upperClass1 (can be deduced from the
first 2 triples)
PS: In fact, according to our statistics extracted from "Links to YAGO", there
are 1042 classes both considered as leafClass and upperClass.That's why we
doubt there may be duplicated items in this dataset.
Your help would be great appreciated!
Thanks in advance.BRIvan Lv from China
