摘要：
In general, document representation and ranking are dependent on context. In this work, we introduce the notion of optimal context, i.e. a context which gives the best ranking. We develop an algorithm to compute this optimal context and we show that it has an effect of query reformulation. Our approach gives substantial improvements in retrieval performance over known models.
