今天，互联网上有很多参与者之间的大规模讨论，主题从政治争论到团体协调。但是，随着这些讨论增长到成千上万的职位，他们变得越来越难以为读者消化。在本文中，我们描述了一种称为递归摘要的工作流，它在我们的Wikum原型中实现，使大量读者或编辑能够以小剂量工作来提炼讨论的要点。不仅仅是一个单一的摘要，我们的工作流程产生了一个摘要树，使读者能够根据他们的兴趣在多个细节层次上探索不同的子主题。我们描述了实验室评估，表明（i）Wikum可以比控件更有效地用于快速构建摘要树，（ii）摘要树在帮助读者识别和探索主要主题方面比原始讨论更有效。
Large-scale discussions between many participants abound on the internet today, on topics ranging from political arguments to group coordination. But as these discussions grow to tens of thousands of posts, they become ever more difficult for a reader to digest. In this article, we describe a workflow called recursive summarization, implemented in our Wikum prototype, that enables a large population of readers or editors to work in small doses to refine out the main points of the discussion. More than just a single summary, our workflow produces a summary tree that enables a reader to explore distinct subtopics at multiple levels of detail based on their interests. We describe lab evaluations showing that (i) Wikum can be used more effectively than a control to quickly construct a summary tree and (ii) the summary tree is more effective than the original discussion in helping readers identify and explore the main topics.
