从多个垂直搜索引擎中选择和聚合不同类型的内容在网络搜索中变得越来越流行。用户垂直意图，即用户期望与特定信息需求相关的垂直，可能不对应于垂直集合相关性，即包含最相关内容的垂直。在这项工作中，我们提出了不同的方法来定义一组相关的垂直文件的判断的基础上。我们将从这些方法中获得的基于集合的相关垂直与真实的用户垂直意图相关联，并表明它们可以相对较好地对齐。因此，由这些方法定义的相关垂直集可以作为评估垂直选择的近似但可靠的基础事实，避免收集明确的用户垂直意图的需要，反之亦然。
Selecting and aggregating different types of content from multiple vertical search engines is becoming popular in web search. The user vertical intent, the verticals the user expects to be relevant for a particular information need, might not correspond to the vertical collection relevance, the verticals containing the most relevant content. In this work we propose different approaches to define the set of relevant verticals based on document judgments. We correlate the collection-based relevant verticals obtained from these approaches to the real user vertical intent, and show that they can be aligned relatively well. The set of relevant verticals defined by those approaches could therefore serve as an approximate but reliable ground-truth for evaluating vertical selection, avoiding the need for collecting explicit user vertical intent, and vice versa.
