This paper presents an Information Extraction approach to extract events and entities from ISAD(G) elements with semi-structured text descriptions. Natural Language processing is done by using two methodologies: the ANNIE system, by defining proper Gazetteers and Jape rules to process the text and extract the intended information; and a reduced Portuguese BERT Language model that is fine-tuned for Semantic Role Labelling. The evaluation of the Information Extraction processes is done in a sample of 1000 records, for each type of information, and a corresponding dataset is manually built for each type of information considered, baptism events and passport requisitions. The CIDOC-CRM knowledge base is automatically populated with newly linked events and entities, using several automatic information extraction processes. The use of SPARQL queries to explore the information represented in CIDOC-CRM, obtained from the migration of DigitArq records and extracted from text descriptions, allows new ways of visualising the archival records and retrieving information from different sources, including archives digital repositories.
