Abstract | The effects of word recognition errors (WRE) in spoken documents on the performance of an Information Retrieval (IR) system have been well studied and well reported in recent IR literature. Most of the research in this direction has been promoted by the Spoken Document Retrieval track of TREC. Much less experimental work has been devoted to studying the effects of WRE in spoken queries. It is easy to imagine that given the typical length of the user query, the effects of WRE in queries on the performance of an IR system must be destructive. The experimental work reported in this paper intends to test that. The paper reports on the background of such a study, on the construction of a test collection, and on the first experimental results. The preliminary conclusions drawn from the experimentation enable to give some useful indications for the design of spoken query systems, despite the recognized limitations of the study. |
