The search paradigm for finding information of interest in massive text corpora is well established, and exemplified by the success of Web search engines. The next frontier is the support of sense-making out of medium to large scale text corpora by the domain expert and analyst, who is trying to untap the tacit knowledge hidden in the text. In contrast to Web search, where the user's information need is satisfied by a few high-quality results, the domain analyst typically needs to find all relevant documents related to a topic of interest. Furthermore the domain analyst's information need is often much too complex to be easy to express in a small number of query terms. These requirements are very different from those of a web search engine. This project aims towards algorithms and systems that will address such requirements, in the context of use cases of significant practical interest including: reports on factory worker incidents and on aviation incidents; court decisions in the common law legal system; medical research literature for generation of systematic reviews; and prior art patent search. Key challenges include: vocabulary mismatch, where the queries of the user contain a vocabulary that is different from that used in the relevant documents; design of interactive mechanisms and visualizations to support the interactive nature of and incorporate human feedback into the retrieval process. The impact of the proposed research will be improvement of safety in a variety of domains where incidents are recorded and studied to obtain insights on how to prevent future incidents, such as in factories, aviation, hospitals and old-age homes.

在大量文本语料库中查找感兴趣的信息的搜索范式已经很好地建立起来，Web搜索引擎的成功就是一个例子。下一个前沿是由领域专家和分析人员从中大型文本语料库中支持意义制造，他们试图挖掘隐藏在文本中的隐性知识。在Web搜索中，用户的信息需要通过一些高质量的结果来满足，与此相反，域分析人员通常需要找到与感兴趣的主题相关的所有相关文档。此外，领域分析人员的信息需求往往过于复杂，难以用少量的查询术语来表达。这些要求与网络搜索引擎的要求非常不同。该项目旨在开发能够满足这些要求的算法和系统，在具有重大实际意义的用例背景下，包括：工厂工人事件和航空事件的报告；普通法法律体系中的法院判决；生成系统评价的医学研究文献；以及现有技术专利检索。主要的挑战包括：词汇表不匹配，即用户的查询包含的词汇表与相关文档中使用的词汇表不同；交互机制和可视化的设计，以支持交互的本质，并将人类反馈整合到检索过程中。拟议研究的影响将是改善各种领域的安全，这些领域记录和研究事件，以获得如何预防未来事件的见解，例如工厂、航空、医院和养老院。
