Status

Status

  • Entity Search & Fact Search implemented in SAW 1

    • But limited interaction between the two

    • Thus misses some of the recursive nature of browsing entities and facts (entities participate in facts, that contain entities, etc.)

  • Prototype of Fact Chain Search implemented in a SAW 1 variant

    • No metrics for “interestingness” of chains yet

  • Fact Search implemented in SAW 2

    • More capabilities on the way

  • Fact Pattern Search: Future work
