Automatic Extraction of NV Expressions in Basque: Basic Issues on Cooccurrence Techniques
Antton Gurrutxaga, Iñaki Alegria · 2011
Taking as a starting-point the development on cooccurrence techniques for several languages, we focus on the aspects that should be considered in a NV extraction task for Basque. In Basque, NV expressions are considered those combinations in which a noun, inflected or not, is co-occurring with a verb, as erabakia hartu (‘to make a decision’), kontuan hartu (‘to take into account’) and buruz jakin (‘to know by heart’). A basic extraction system has been developed and evaluated against two references: a) a reference which includes NV entries from several lexicographic works; and b) a manual evaluation by three experts of a random sample from the n-best lists. 1
