针对未充分指定的查询的多样化搜索结果通常包含其中存在与查询的不同方面相关的答案的网页。为了帮助用户找到这样的相关答案，我们提出了一个简单的扩展标准的搜索引擎结果页面（SERP）接口，称为AspecTiles。除了呈现URL的标题和片段的排名列表之外，AspecTiles还通过彩色方块（“瓷砖”）可视化文档与每个方面的相关程度。为了比较AspecTiles与标准SERP界面的实用性，我们进行了一项用户研究，涉及30个搜索任务，设计的基础上TREC网络多样性任务主题，以及32名参与者。我们的研究结果表明，AspecTiles在搜索性能，用户行为和用户满意度方面具有一定的优势。首先，AspecTiles使用户能够比标准SERP接口更有效地收集相关信息，用于用户认为查询的几个不同方面同时重要的任务（多方面任务）。其次，AspecTiles影响用户的信息寻求行为：有了这个界面，我们观察到显着更少的查询重新制定，更短的查询和更深入的检查排名列表在多方面的任务。第三，我们的用户研究的参与者发现AspecTiles在查找相关信息方面比标准SERP界面更有用，并且更易于使用。这些结果表明，简单的接口，如AspecTiles可以提高搜索性能和搜索体验的用户时，他们的查询是欠指定。
A diversified search result for an underspecified query generally contains web pages in which there are answers that are relevant to different aspects of the query. In order to help the user locate such relevant answers, we propose a simple extension to the standard Search Engine Result Page (SERP) interface, called AspecTiles. In addition to presenting a ranked list of URLs with their titles and snippets, AspecTiles visualizes the relevance degree of a document to each aspect by means of colored squares ("tiles"). To compare AspecTiles with the standard SERP interface in terms of usefulness, we conducted a user study involving 30 search tasks designed based on the TREC web diversity task topics as well as 32 participants. Our results show that AspecTiles has some advantages in terms of search performance, user behavior, and user satisfaction. First, AspecTiles enables the user to gather relevant information significantly more efficiently than the standard SERP interface for tasks where the user considers several different aspects of the query to be important at the same time (multi-aspect tasks). Second, AspecTiles affects the user's information seeking behavior: with this interface, we observed significantly fewer query reformulations, shorter queries and deeper examinations of ranked lists in multi-aspect tasks. Third, participants of our user study found AspecTiles significantly more useful for finding relevant information and easy to use than the standard SERP interface. These results suggest that simple interfaces like AspecTiles can enhance the search performance and search experience of the user when their queries are underspecified.
