中文简介:
创建和维护知识库的主要任务之一是验证事实并为其提供来源,以确保所提供知识的正确性和可追溯性。到目前为止,这项任务通常是由人工管理者在三个步骤中完成的:为声明发布适当的关键字查询,以使用标准搜索引擎进行检查,检索潜在的相关文档,并筛选相关内容的文档。这个过程的缺点是多方面的。最重要的是,这是非常耗时的,因为专家必须执行几个搜索过程,必须经常阅读几个文档。在本文中,我们介绍了defacto(深层事实验证)——一种通过在Web上为事实找到可靠来源来验证事实的算法。defacto旨在通过向用户提供网页的相关摘录以及有用的附加信息(包括defacto对输入事实正确性的信心分数)来提供验证事实的有效方法。
课程简介: One of the main tasks when creating and maintaining knowledge bases is to validate facts and provide sources for them in order to ensure correctness and traceability of the provided knowledge. So far, this task is often addressed by human curators in a three-step process: issuing appropriate keyword queries for the statement to check using standard search engines, retrieving potentially relevant documents and screening those documents for relevant content. The drawbacks of this process are manifold. Most importantly, it is very time-consuming as the experts have to carry out several search processes and must often read several documents. In this article, we present DeFacto (Deep Fact Validation) – an algorithm for validating facts by finding trustworthy sources for it on the Web. DeFacto aims to provide an effective way of validating facts by supplying the user with relevant excerpts of webpages as well as useful additional information including a score for the confidence DeFacto has in the correctness of the input fact.
