Query: Enriching Bibliographic Data by Combining String Matching and the
  Wikidata Knowledge Graph to Improve the Measurement of International Research
  Collaboration   Measuring international research collaboration is necessary when evaluating,
for example, the efficacy of policy meant to increase cooperation between
countries, but is currently very difficult as bibliographic records contain
only affiliation data from which there is no standard method to identify the
relevant countries. In this paper we describe a method to address this
difficulty, and evaluate it using both general and domain-specific data sets.
