Abstract
In this article we consider the phenomenon of answering a query with a query. Although such answers are common, no large scale, corpus-based characterization exists, with the exception of clarification requests. After briefly reviewing different theoretical approaches on this subject, we present a corpus study of query responses in the British National Corpus and develop a taxonomy for query responses. We point at a variety of response categories that have not been formalized in previous dialogue work, particularly those relevant to adversarial interaction. We show that different response categories have significantly different rates of subsequent answer provision. We provide a formal analysis of the response categories in the framework of KoS.

We offer a formal explication of the coherence that underlies the various different types of query responses within the framework of KoS (Ginzburg 2012)
We suggest that a dialogue like (32) works in a similar way: A’s answer to B’s question (32(2)) can satisfy B, which will lead to the question ?WishDiscuss(B, q1) being positively resolved, enabling B to peffreec: tsLqau: tdefqasu=ctdMts=op=v?e,Npp= orrene.R.Aqfaeucsccdotesl:pv∪pte(o(spspperket:r(.,SQqaeudutdde(P,rsf,trapioco)ptns))) .Q’
Summary
A corpus based taxonomy of query responses was presented. In what follows we present a corpus study that led to the classification. A study using the BNC is discussed, the class distribution over specific genres is presented. This study used a sample of 1,051 query – query response pairs from the BNC. The collected sample covers a wide range of dialogue domains, like interviews, radio and TV broadcasts, tutorials, meetings, training sessions or medical consultations (blocks D, F, G, H, J, K of the BNC). To guide the classification process we used the following questions: 1. More details about the SCoRE syntax see http://www.dcs.qmul.ac.uk/imc/ ds/score/help.html [ 11 ]
