Towards Knowledge Graph Profiling
Knowledge Graphs, such as DBpedia, YAGO, or Wikidata, are valuable resources for building intelligent applications like data analytics tools or recommender systems. Understanding what is in those knowledge graphs is a crucial prerequisite for selecing a Knowledge Graph for a task at hand. Hence, Knowledge Graph profiling – i.e., quantifying the structure and contents of knowledge graphs, as well as their differences – is essential for fully utilizing the power of Knowledge Graphs. In this talk, I will talk about methods for Knowledge Graph profiling, discuss crucial differences of the big, well-known Knowledge Graphs, and throw a glance at current developments of new, complementary Knowledge Graphs such as WebIsALOD and DBkWik.
