Detecting policy fields in German parliamentary materials with Heterogeneous Information Networks and Node Embeddings

This short paper illustrates a combination of Heterogeneous Information Networks (HINs) and Node Embeddings for application in policy research. HIN-based methodology is useful to cope with the dynamic and permeable ontology of policy fields, as it allows to integrate various entities and political interactions within a single network, prepared for diverse analytical operations. The paper presents the theoretical foundations, basic network construction and potential use cases for applied policy studies.
