在本文中，我们研究的问题，排名候选扩展查询扩展条款。我们展示了，传统的F4方案的扩展，部分相关性评估（如何相关的文件）和明示证据（当文件被评估相关）可以被纳入一个长期的排名功能。然后，我们调查这个新的长期排名功能在三个用户实验，检查我们的功能的自动和交互式查询扩展的性能。我们表明，新的功能不仅建议的条款，搜索者的首选，但建议的条款，可以导致更多的使用扩展条款。
In this paper we examine the problem of ranking candidate expansion terms for query expansion. We show, by an extension to the traditional F4 scheme, how partial relevance assessments (how relevant a document is) and ostensive evidence (when a document was assessed relevant) can be incorporated into a term ranking function. We then investigate this new term ranking function in three user experiments, examining the performance of our function for automatic and interactive query expansion. We show that the new function not only suggests terms that are preferred by searchers but suggests terms that can lead to more use of expansion terms.
