In this paper we calculate and analyse the lexical ambiguity of queries in a crosslingual Image Retrieval (Flickling) and compare it with the results obtained by users. We want to know to what extent the lexical ambiguity of a query influences the correct localization of an image in a multilingual framework. With this, our final objective is to determine the necessity of Word Sense Disambiguation systems in Information Retrieval tasks, according to user behaviour. The results show that users really deal with lexical ambiguity: in general terms, users find the correct image with low ambiguity queries.
