论文摘要
传统上,因果关系是通过将原因与效应联系起来来产生知识的科学方法。从想象的角度来看,因果图是表示和推断新因果信息的有用工具。在以前的作品中,我们通过分析文档集并以这种视觉方式来提取并代表发现的因果信息,从而自动生成了与给定概念关联的因果图。检索到的信息表明,因果关系经常不完美而不是精确,该特征由图形收集。在这项工作中,我们将尝试通过概率改善引用图中不精确的管理来进一步对图中的不确定性进行建模。
Causality has traditionally been a scientific way to generate knowledge by relating causes to effects. From an imaginery point of view, causal graphs are a helpful tool for representing and infering new causal information. In previous works, we have generated automatically causal graphs associated to a given concept by analyzing sets of documents and extracting and representing the found causal information in that visual way. The retrieved information shows that causality is frequently imperfect rather than exact, feature gathered by the graph. In this work we will attempt to go a step further modelling the uncertainty in the graph through probabilistic improving the management of the imprecision in the quoted graph.
