Framework for Weakly Supervised Causal Knowledge Extraction from Text
In this paper, we address the problem of extracting causal knowledge from text documents in a weakly supervised manner. We target use cases in decision support and risk management, where causes and effects are general phrases without any constraints. We present a unified framework that supports three classes of tasks with varying degrees of available information. We provide approaches for each of the tasks using pre-trained, Natural Language Inference (NLI) and Question Answering (QA) models. We present a novel evaluation scheme and use existing and new benchmark data sets to measure the relative performance of each of the approaches.

Weakly Supervised Multilingual Causality Extraction from Wikipedia
We present a method for extracting causality knowledge from Wikipedia, such as Protectionism -{\textgreater} Trade war, where the cause and effect entities correspond to Wikipedia articles. Such causality knowledge is ea…

In this paper, we propose a novel problem of automatic extraction of tasks from text. A task is a well-defined knowledge-based volitional action. We describe various characteristics of tasks as well as compare and contra…
Weakly-supervised causal discovery based on fuzzy knowledge and complex data complementarity
Causal discovery based on observational data is important for deciphering the causal mechanism behind complex systems. However, the effectiveness of existing causal discovery methods is limited due to inferior prior know…
