airpediaProject aims to extract structured information from Wikipedia. And other unstructured or semi-structured sources) and make it freely available. One can query the dataset using our SPARQL endpoint. The project is mainly based on DBpedia. That uses Wikipedia infoboxes to extract information. Our approach uses a machine learning algorithm that, starting from pages included in DBpedia, trains a classifier that extracts new instances of pages when the infobox is not present. 25/01/2015 Source code released.
