Machine Learning and Knowledge Extraction, Volume 2, Issue 4

2020 December - 16 articles

Cover Story: Quantifying the extent to which Environmental, Social and Governance (ESG)-related conversations are carried out by companies is essential to objectively assess the impact of ESG on business operations. This research study detects historical trends in ESG discussions by analyzing the transcripts of corporate earning calls. It exploits recent advances in neural language modeling to understand the linguistic structure in ESG discourse. We develop a classification system that categorizes the relevance of a text sentence to ESG by fine-tuning a language model on sustainability reports. The semantic knowledge encoded in the classification model is then leveraged by applying it to the sentences in the conference transcripts using a novel distant-supervision approach. A trend analysis of earnings calls based on this transfer learning framework indicates that ESG factors are integral to business strategy. View this paper
