Summary

This is a paper that introduces an autonomous system for refining Wikipedia’s infobox information schema to create a cleanly-structured ontology. Advanced query capability, improved information extractors and semiautomatic generation of new infobox templates are shown as advantages of a refined ontology. The ontology refinement problem is solved using both Support Vector Machines and a more powerful joint-inference approach expressed in Markov Logic Networks.

The autonomous system, presented as Kylin Ontology Generator (KOG), is comprised of three modules:

  • Schema Cleaner, which merges duplicate classes and attributes and prunes rarely-used ones
  • Subsumption Detector,
  • Schema Mapper,
