Automatic extraction of Word Combinations from corpora: Evaluating methods and benchmarks

English. We report on three experiments aimed at comparing two popular methods for the automatic extraction of Word Combinations from corpora, with a view to evaluate: i) their efficacy in acquiring data to be included in a combinatory resource for Italian; ii) the impact of different types of benchmarks on the evaluation itself. Italiano. Presentiamo i risultati di tre esperimenti che mirano a confrontare due metodi di estrazione automatica di combinazioni di parole da corpora, con lo scopo di: (i) valutare l’efficacia dei due metodi per acquisire dati da includere in una risorsa combinatoria per l’italiano, e (ii) analizzare e confrontare i metodi di valutazione stessi.
