Extracting MWEs from Italian corpora: A case study for refining the POS-pattern methodology
Sara Castagnoli · 2014
An established method for MWE extraction is the combined use of previously identified POS-patterns and association measures.However, the selection of such POSpatterns is rarely debated.Focusing on Italian MWEs containing at least one adjective, we set out to explore how candidate POS-patterns listed in relevant literature and lexicographic sources compare with POS sequences exhibited by statistically significant n-grams including an adjective position extracted from a large corpus of Italian.All literature-derived patterns are found-and new meaningful candidate patterns emerge-among the top-ranking trigrams for three association measures.We conclude that a final solid set to be used for MWE extraction will have to be further refined through a combination of association measures as well as manual inspection.
