摘要

重复使用检索系统的用户可能被认为具有连续使用的共同上下文(即使当前需求不同)。能够利用这一背景的红外系统可能能够更好地满足具体需要。描述了一种推断用户上下文的机器学习方法，并给出了评估实验的结果。红外系统似乎有以这种方式运作的余地。

Context learning in Okapi

A user who makes repeated use of a retrieval system may be assumed to have a context which is common to successive uses (even if the immediate need differs). An IR system which could make use of this context may be better able to match the specific need. A machine‐learning approach to inferring the user’s context is described, and the results of an evaluation experiment are given. There appears to be scope for IR systems to operate in this way.
