Main strategies for building wordnetsExpand approach: translate WordNet synsets to another language and take over the structure
easier and more efficient method
compatible structure with WordNet
vocabulary and structure is close to WordNet but also biased
can exploit many resources linked to Wordnet: SUMO, Wordnet domains, selection restriction from BNC, etc...
Merge approach: create an independent wordnet in another language and align it with WordNet by generating the appropriate translations
more complex and labor intensive
different structure from WordNet
language specific patterns can be maintained, i.e. very precise substitution patterns
