In 2019 the administration of the Norwegian Parliament designed and adopted a strategic goal for digitization: The Parliament shall exchange, process, publish and preserve parliamentary information digitally and efficiently, with good quality. One outcome of this effort was the project “StorSak”. This project aims to implement an information system which handles document production and parliamentary proceedings in a coherent digital value-chain. One of the investment areas in the StorSak project is exploring the use of machine learning (ml) and artificial intelligence (ai). The project quickly singled out metadata handling as an area of interest, and the categorization of documents and proceedings using theme wording.
