面向新兴话题的网络搜索，如何让信息更可信、动态、易理解？
A Research Vision for Web Search on Emerging Topics
- 提出支持新兴话题搜索的三类核心研究问题
- 强调动态知识更新与信息可信度的挑战
- 适合关注信息可信性与搜索系统设计的研究者
我们经常需要了解尚在发展中的新兴话题，例如当前事件。网络搜索是获取此类信息的主要方式，但新兴话题的信息稀疏且动态变化，质量与可信度不确定，易受误导性内容和偏见影响。本文提出一个研究愿景，旨在构建支持有效知识获取、认知话题动态性、负责任意见形成的搜索系统与界面。为此，我们提出三个核心研究问题：理解现状、明确系统需求、构建相应系统。针对每个问题，综述相关文献并指出潜在解决路径。最后讨论实现该愿景可能面临的技术与伦理挑战。
原文摘要 · Abstract (English)
We regularly encounter information on novel, emerging topics for which the body of knowledge is still evolving, which can be linked, for instance, to current events. A primary way to learn more about such topics is through web search. However, information on emerging topics is sparse and evolves dynamically as knowledge grows, making it uncertain and variable in quality and trustworthiness and prone to deliberate or accidental manipulation, misinformation, and bias. In this paper, we outline a research vision towards search systems and interfaces that support effective knowledge acquisition, awareness of the dynamic nature of topics, and responsible opinion formation among people searching the web for information on emerging topics. To realize this vision, we propose three overarching research questions, aimed at understanding the status quo, determining requirements of systems aligned with our vision, and building these systems. For each of the three questions, we highlight relevant literature, including pointers on how they could be addressed. Lastly, we discuss the challenges that will potentially arise in pursuing the proposed vision.
