Wikidata is a structured knowledge base, that aims to curate consistent and high-quality data across the various Wikipedia language versions. The Wikidata approach is based on a number of design decisions, such as open editing, plurality (conflicting data being allowed) and multilingual data (Vrandecic  & Krötzsch, 2014). In our research, we assume that Wikidata combines the characteristics of a peer-production system and a collaborative ontology engineering project (Müller-Birn et al., 2015). In our research, we try to enhance our understanding of collaborative processes of ontology engineering in this open context. This will allow us, to develop better tools for development structured vocabularies collaboratively.

We seek therefore for a highly motivated B.Sc. or M.Sc. student who wants to write her/his thesis in one of the following context:

  • Developing a tool that allows the semi-automatic creation of RDF-conform representations (Erxleben et. al, 2014) based on the provided data sets (B.Sc./MSc.)
  • Developing a parser that analysis existing discussion within the property name space (B.Sc./M.Sc.)
  • Developing an exemplary interactive visualization for concepts in Wikidata (B.Sc./M.Sc.)
