Conversational Graph-Based Navigation Over Semantically Connected Content

The COGNOSCO project (from Latin cognōscere: to discover/learn/know) aims at investigating conversational search systems that enable explorative navigation in scientific knowledge repositories. Digital publication libraries provide access to millions of scientific documents from journals, books, protocols, workshops, or proceedings. Various scenarios how scientists discover and learn new insights from these resources are considered. In this context, conversational search systems can interact with humans naturally and offer assistance. With the help of knowledge graphs, structured as well as unstructured textual data are semantically linked during the information search and presented in an understandable format. The search process itself is controlled by an interactive text-based dialog with the system. In addition to the theoretical contributions of the project, a prototype system is developed and evaluated in real-world settings.
