The First Tax Return Assessment Expert System

Abstract: In realising the first Tax Return Assessment Expert System in Switzerland we had first to make a convincing business case for an AI innovation in a traditional governmental environment, secondly to show in the daily business environment that what can be demonstrated to be viable in theory does also work in practice, thirdly to minimize the gap between the tacit knowledge in the head of assessment experts and the explicit model of expertise that specifies the domain knowledge and finally to minimize the gap between the specified expert knowledge and the system knowledge formalized in the knowledge base. We present the project, our approach to meeting these challenges, the current state of the productive system and a sketch of the final system under development. 1
