Currently, web search engines reliably display knowledge panels with summarizing information only when the issued query mentions exactly one entity. That being said, queries mentioning multiple entities are relatively common. The present paper introduces a testbed for developing and evaluating dual-entity knowledge panels. The idea is to populate these novel knowledge panels with an explanation of the relationship between the entities of dual-entity queries in order to serve the users’ information need. To this end, previous research showed the feasibility of finding paths in Wikidata that connect two arbitrary entities. Although such paths provide a rich foundation for elucidating the relationship between two entities, it has not yet been studied how to present them in this context with usability in mind. Hence, this paper showcases a selection of conceivable presentation formats, including graph-based visualizations and LLM-based textual approaches, to promote research in this direction
