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 pol- icy research. HIN-based methodology is use- ful to cope with the dynamic and permeable ontology of policy fields, as it allows to in- tegrate various entities and political interac- tions within a single network, prepared for di- verse analytical operations. The paper presents the theoretical foundations, basic network con- struction and potential use cases for applied policy studies.
