Interactive exploration of large knowledge graphs

  • Interactive – Starts from a single entity and guides the user towards the results
  • Expressive – explore the results with Exemplar Queries [1] and Multiple Exemplar [2]
  • Fast – takes less than 1s to get the results

In this demontration paper:

  • We showcase \(\tt X_2Q\) a search-and-explore interactie system to explore large knowledge graphs
  • We demonstrate the effectiveness of the exemplar query paradigm
  • We remove the need of complex query languages and natural language ambiguity
  • We suggest and guide the user towards the answer easily and fast
