From domain-specific MWEs to the terminology

l over 70% of the terms are composed of more than one

word (Krieger and Finatto (2004)) – Multiword Terms (MWTs)

l domain-specific MWEs are difficult to detect

automatically

l morphosynthatic analysis is used to improve the

extraction of MWE

l for MWTs extraction, it is necessary to know the relevant

syntactic structures used in particular language and the domain for expressing specific concepts

Results

716000 tokens in total 29,753 expressions of the A N structure (~12000 unique) 34% of the 1000 top frequent were MWTs from the agricultural engineering domain angažovana snaga (engaged power), aromatično bilje (aromatic plants), genetički potencijal (genetic potential), hidraulički sistem (hydraulic system) najveći broj (maximum number), nova tehnologija (new technology), dobijeni rezultat (obtained result)
