当用户在Web上查找信息时，他们对不同的任务类型表现出不同的行为，例如，用于事实调查和信息收集任务。例如，这一领域的相关工作已经研究了如何测量这种行为并将其应用于区分简单和困难的任务。在这项工作中，我们看看在新闻领域的四个不同的任务类型，另外，在每个任务类型的两个不同的主题的行为。搜索行为是衡量与会话变量和相关的主观措施，如任务难度，任务成功和有用的文件。我们承认在这方面的任务难度与用户的努力，容易和困难的任务是可区分的会话变量之前的结果。然而，在这项工作中，我们强调任务主题的作用-本身-在参数，如搜索结果和阅读内容页面，停留时间，会话变量和主观的措施，如任务难度或任务成功。有了这些知识，研究人员应该更多地关注任务主题作为用户行为的重要影响因素。
When users are looking for information on the Web, they show different behavior for different task types, e.g., for fact finding vs. information gathering tasks. For example, related work in this area has investigated how this behavior can be measured and applied to distinguish between easy and difficult tasks. In this work, we look at the searcher's behavior in the domain of journalism for four different task types, and additionally, for two different topics in each task type. Search behavior is measured with a number of session variables and correlated to subjective measures such as task difficulty, task success and the usefulness of documents. We acknowledge prior results in this area that task difficulty is correlated to user effort and that easy and difficult tasks are distinguishable by session variables. However, in this work, we emphasize the role of the task topic - in and of itself - over parameters such as the search results and read content pages, dwell times, session variables and subjective measures such as task difficulty or task success. With this knowledge researchers should give more attention to the task topic as an important influence factor for user behavior.
