Answering Binary Causal Questions: A Transfer Learning Based Approach

Abstract: Causal question answering is a task of answering causality related questions. The questions are referred to as binary causal questions when the questions e.g., "Could X cause Y?" can be answered by yes/no answers. Answer to the previous question is yes if X is a cause of Y , and otherwise no. The binary causal question answering systems can be used to validate causal relationships, which can be particularly useful for decision making. For example, it could be useful for the tourism authorities to know the answ… Show more

“…Hassanzadeh et al evaluate the application of cause-effect pairs extracted from Gigawords corpus for binary question answering. Kayesh et al (2020) extends this work to automatically learn the yes/no threshold using word embeddings from BERT, RoBERTa, and other transformer-based models. Sharp et al and Xie and Mu (2019) Li et al (2021) present SCITE, a BiLSTM-CRF model which uses pretrained Flair embeddings and multi-headed self-attention to extract causal phrases.…”

“…Therefore, the recent approaches apply supervised or weakly-supervised learning in causal discovery [14], [15]. Transfer learning-based approaches are also among the popular techniques for causality detection [1], [16], [2], [17].…”

“…Because of the syntactic diversity of concepts in natural languages, an exact match between knowledge base concepts and input concepts is not always available. The recent approaches to BCQs apply transfer learningbased models that are trained on automatically extracted causally-related concept pairs [1], [2]. Hassanzadeh et al [1] proposed an approach that uses bidirectional encoder representation from transformers [3] to encode a large training dataset and then applies a top-k nearest neighbour search technique to answer binary causal questions.…”
