Development of Natural Language Processing-based Solutions for Risk Analysis: application to a hydropower company and an O&G industry

Development of Natural Language Processing-based Solutions for Risk Analysis: application to a hydropower company and an O&G industry (2022)

 

Supervisors: Prof. Dr. Márcio José das Chagas Moura, Prof. Dr. Enrico Zio

Keywords: Risk analysis; accident investigation reports; natural language processing; text mining; oil refineries; hydroelectric power company

This research aims to address the challenges in Risk Analysis (RA) by developing innovative Natural Language Processing (NLP) solutions. To improve RA, the study develops Natural Language Processing (NLP) models to extract and organize information from textual data, including proactive data from preliminary risk studies and accident investigation reports. Two methodologies are presented: one identifies issues in accident reports, aiding safety technicians in proposing improvements, while the other automates risk feature identification for the initial stage of Quantitative Risk Analysis (QRA) in Oil and Gas industries. The research aims to prevent occupational and major accidents, reducing environmental, economic, and human losses.
