The integration of artificial intelligence in libraries can have a wide impact on the evolution of information access and management. It allows both the streamlining of internal processes and the transformation of the way users interact with information resources, thereby enhancing effectiveness and operational efficiency while enriching the user experience. This article presents the experience of incorporating several artificial intelligence techniques in the Library of the National Congress of Chile and describes three initiatives: (1) publishing legislation as linked open data with Semantic Web technologies, combining machine-readable comprehension with high standards of interoperability; (2) maintaining the history of legislation via the automatic tagging of legislative documentation with natural language processing; and (3) predicting law approval based on the current political context using machine learning. The use of these technologies has allowed the library to offer a wide variety of knowledge management services, providing useful and timely information for parliamentary work as well as automated human-based repetitive tasks for the efficient use of public resources.
