The paper discusses the traditional, and ongoing, question as to whether natural language processing (NLP) techniques, or indeed and representational techniques at all, aid in the retrieval of information, as that task is traditionally understood. The discussion is partly a response to Karen Sparck Jones’ (1999) claim that artificial intelligence, and by implication NLP, should learn from the methodology of Information Retrieval (IR), rather than vice versa, as the first sentence above implies. The issue has been made more interesting and complicated by the shift of interest from classic IR experiments with very long queries to Internet search queries which are typically of two highly ambiguous terms. This simple fact has changed the assumptions of the debate. Moreover, the return to statistical and empirical methods with NLP have made it less clear what an NLP technique, or even a “representational” method, is. The paper also notes the growth of “language models” within IR and the use of the term “translation” in recent years to describe a range of activities, including IR, and which constitutes rather the opposite of what Sparck Jones was calling for.
