Presentation transcript:

Intelligent Database Systems Lab Presenter : Chang,Chun-Chih Authors : David Milne *, Ian H. Witten 2012, AI An open-source toolkit for mining Wikipedia

Intelligent Database Systems Lab Outlines Motivation Objectives Methodology Experiments Conclusions Comments

Intelligent Database Systems Lab 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

Intelligent Database Systems Lab 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.

Intelligent Database Systems Lab Methodology - Architecture of the wikipedia Miner toolkit

Intelligent Database Systems Lab Methodology - Measuring relatedness between concepts

Intelligent Database Systems Lab Methodology - Measuring relatedness between concepts

Intelligent Database Systems Lab Methodology -Features for measuring artucle relatedness

Intelligent Database Systems Lab Experiments - Impact of thresholds for disambiguation and detection

Intelligent Database Systems Lab Experiments - Impact of relatedness dependencies

Intelligent Database Systems Lab Experiments - Impact of traning data

Intelligent Database Systems Lab Experiments - performance of the disambiguator

Intelligent Database Systems Lab Experiments - performance of the detector

Intelligent Database Systems Lab 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.

Intelligent Database Systems Lab Comments Advantages Applications - wikipedia - Disambiguation - Annotation
