中文简介:
网络搜索往往简短而含糊。因此,Web查询消歧是一个积极研究的课题也就不足为奇了。然而,大多数现有的工作依赖于搜索引擎日志数据的存在,在这些日志数据中,每个用户的搜索活动都被长时间记录下来。这些方法可能会引起对隐私的关注,而且由于实际原因可能难以实施。在这项工作中,我们提出了一种Web查询消除歧义的方法,它的预测只基于对用户搜索活动的短暂一瞥,平均在5到6次之前的搜索中捕获。我们的方法基于马尔可夫逻辑,利用当前的搜索会话之间的关系来预测用户的意图。我们提供的实证结果证明了我们的方法对从一个商业通用搜索引擎收集的数据的有效性。
课程简介: Web searches tend to be short and ambiguous. It is therefore not surprising that Web query disambiguation is an actively researched topic. However, most existing work relies on the existence of search engine log data in which each user's search activities are recorded over long periods of time. Such approaches may raise privacy concerns and may be difficult to implement for pragmatic reasons. In this work, we present an approach to Web query disambiguation that bases its predictions only on a short glimpse of user search activity, captured in a brief session of about 5--6 previous searches on average. Our method exploits the relations of the current search session in which the ambiguous query is issued to previous sessions in order to predict the user's intentions and is based on Markov logic. We present empirical results that demonstrate the effectiveness of our proposed approach on data collected form a commercial general-purpose search engine.
