User Behaviour and Lexical Ambiguity in Cross-Language Image Retrieval

摘要

Our objective in this paper is to determine the necessity of Word Sense Disambiguation in Information Retrieval tasks, according to user behaviour. We estimate and analyse the lexical ambiguity of queries in Cross-Language Image Retrieval (using search logs from a multilingual search interface for Flickr) and measure its correlation with search effectiveness. We show to what extent the lexical ambiguity of a query can influence the successful retrieval of an image in a multilingual framework.
