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.
