The document discusses a research project called IMPACT that aims to develop tools to help with policymaking and public participation. It focuses on an argument visualization tool called PolicyCommons that will allow users to navigate and explore arguments in policy documents and consultations. The tool is based on previous research in computer-supported argument visualization and aims to advance the field by improving techniques for laying out and understanding large argument maps. It is argued that the tool could help policymakers, analysts, and the public engage with policy issues by making the arguments for and against different options more transparent and accessible.
