   • 2007, Faye Rochelle Baron, Identifying non-compositional idioms in text using WordNet synsets‎:

     Any natural language processing system that does not have a knowledge of non-compositional idioms and their interpretation will make mistakes. Previous authors have attempted to automatically identify these expressions through the property of non-substitutability: similar words cannot be successfully substituted for words in non-compositional idiom expressions without changing their meaning.

This is especially true for Chinese and Japanese, whose scripts present linguistic and algorithmic challenges not found in other languages.
