By using multiple standard metrics in information retrieval solutions, the study measures how the Portuguese BERT performs as a semantic search solution on Portuguese Retirement Law by comparing its answers with a testing set composed of 180 questions and answers provided by INCM. The study revealed that the solution showed positive results. A form was also distributed to INCM, which indicated positive feedback when comparing it with the current solution implemented. This project showed that the Portuguese BERT is a very promising tool that can be used for Extractive Question Answering and for semantic search on various other domains.engData scienceBusiness analyticsBusiness and data analyticsNlpBertExtractive qaSemantic searchmaster thesis203231953
