We present Mobipedia, an integrated knowledge base withinformation about 1 million mobile applications (apps) such as their cat-egory, meta-data (author, reviews, rating, release date), permissions andlibraries used, and similar apps. The goal of Mobipedia is to integrateunstructured and semi-structured data about mobile apps from publiclyavailable data sources and publish it as Linked Data using RDF. We de-scribe the extraction process for facts, access mechanisms to the knowl-edge base, and an overview of applications facilitated by Mobipedia.
