Non-compositional expressions present a special challenge to NLP applications. We present a method for automatic identification of non-compositional ex- pressions using their statistical properties in a text corpus. Our method is based on the hypothesis that when a phrase is non-composition, its mutual infor- mation differs significantly from the mutual infor- mations of phrases obtained by substituting one of the word in the phrase with a similar word.
