  1. An open-source toolkit for mining Wikipedia Presenter : Chang,Chun-ChihAuthors : David Milne *, Ian H. Witten2012, AI

  2. Outlines • Motivation • Objectives • Methodology • Experiments • Conclusions • Comments

  3. Motivation • The online encyclopedia Wikipedia is a vast, constantly evolving tapestry of interlinked articles. • For developers and researchers it represents a giant multilingual database of concepts and semantic relations, a potential resource for natural language processing

  4. Objectives • The Wikipedia Miner toolkit, an open-source software system that allows researchers and developers to integrate Wikipedia’s rich semantics into their own applications. • Wikipedia Miner is intended to be a platform for sharing data mining techniques.

  5. Methodology- Architecture of the wikipedia Miner toolkit

  6. Methodology- Measuring relatedness between concepts

  7. Methodology- Measuring relatedness between concepts

  8. Methodology-Features for measuring artucle relatedness

  9. Experiments- Impact of thresholds for disambiguation and detection

  10. Experiments - Impact of relatedness dependencies

  11. Experiments- Impact of traning data

  12. Experiments - performance of the disambiguator

  13. Experiments- performance of the detector

  14. Conclusions • Our aim in releasing this work open source is not to provide a complete and polished product, • but rather a resource for the research community to collaborate around and continue building together.

  15. Comments • Advantages • Applications - wikipedia - Disambiguation - Annotation
