摘要翻译：
与搜索引擎交互的日志显示，用户经常重新定义他们的查询。检查这些重定义会发现，精确查询焦点的建议是有帮助的，就像那些基于原始查询扩展的建议一样。但它也表明，表达相对于原始查询的一些主题转移的查询可以帮助用户更快地访问他们需要的信息。我们提出了一种从过去用户的查询日志中识别聚焦或转移初始查询主题的查询的方法。该方法结合了基于点击、基于主题和基于会话的排序策略，并使用监督学习来最大化查询和推荐之间的语义相似性，同时使它们多样化。我们用一个日本web搜索引擎的查询/点击日志对我们的方法进行了评估，我们表明三种方法的结合比单独使用任何一种方法都要好得多。

英文摘要：
  Logs of the interactions with a search engine show that users often reformulate their queries. Examining these reformulations shows that recommendations that precise the focus of a query are helpful, like those based on expansions of the original queries. But it also shows that queries that express some topical shift with respect to the original query can help user access more rapidly the information they need. We propose a method to identify from the query logs of past users queries that either focus or shift the initial query topic. This method combines various click-based, topic-based and session based ranking strategies and uses supervised learning in order to maximize the semantic similarities between the query and the recommendations, while at the same diversifying them. We evaluate our method using the query/click logs of a Japanese web search engine and we show that the combination of the three methods proposed is significantly better than any of them taken individually.
