Fact extraction from organizational corpora

组织知识可以用事实、关系和事件来描述。这些信息通常在组织内通过备忘录、财务报表、内部和外部帖子、公告板等资源来表达或共享。搜索或处理对此类内容的查询并不容易。建立可搜索的事实组织知识存储库的第一步是从大量文本文档中有效地收集此类知识。在这个项目中，阿尔伯塔大学与总部位于埃德蒙顿的加拿大软件技术和咨询公司 DevFacto 合作，将检查从组织资源和备忘录中提取高质量事实和事件的可行性和有效性。这项工作包括根据公共领域的文献和资源以及阿尔伯塔大学开发的文献和资源，组装一个初步的软件系统，并进行实验来评估其从 DevFacto 识别或提供的组织资源中提取事实和事件的性能。所开发的系统将向DevFacto开发的移动应用程序Sparrow提供数据，以提供更好的组织知识搜索。虽然拟议的项目将主要利用文献中的现有算法，但该项目将识别和组合算法并对其进行评估。某些算法还可以进行扩展或修改，以更好地适用于正在研究的特定领域。该项目将在 DevFacto 行业专家的指导下进行。该项目将为研究生和本科生提供有关信息提取、事件检测和实体解析等主题的培训环境。

Organizational knowledge may be described in terms of facts, relationships and events. This information isoften expressed or shared within an organization in resources such as memos, financial statement, internal andexternal postings, bulletin boards, etc. It is not easy to search or process queries over such content. A first steptoward building a searchable repository of factual organizational knowledge is to effectively collect suchknowledge from large collections of textual documents. In this project, University of Alberta in partnershipwith DevFacto, a software technology and consulting company in Canada with a base in Edmonton, willexamine the feasibility and the effectiveness of extracting high quality facts and events from organizationalresources and memos. The work involves putting together a preliminary software system, based on theliterature and resources in public domain as well as those developed at the University of Alberta, and carry outexperiments to evaluate its performance in extracting facts and events from organizational resources, identifiedor provided by DevFacto. The developed system will feed data to Sparrow, a mobile application developed byDevFacto, to provide a better search of the organizational knowledge.Although the proposed project will mostly leverage existing algorithms from the literature, identifying andcombining the algorithms and evaluating them will be conducted in this project. Some of the algorithms mayalso be extended or revised to better work for the particular domain being studied. The project will beconducted with guidance from industry experts in DevFacto. The project will provide a training environmentfor graduate and undergrad students on topics related to information extraction, event detection and entityresolution.
