Cross-language Ontology Learning:
Incorporating and Exploiting Cross-language
Data in the Ontology Learning Process

Hans Hjelm

Think of the frustrating experience of running into
circular definitions when looking up a word in a
dictionary. Yet – how do we convey the meaning of a
word without referring to meanings of other words?
In ontologies — the object of study in this thesis — this
is exactly what we find: words (or concepts) defined
by their position in a hierarchy of other words and the
relations that hold between them.
