A closer look at the changing dynamics of DBpedia mappings

Polishing a diamond: techniques and results to enhance the quality of DBpedia data

DBpedia is more than a source for creating papers. It is also being used  by companies as a remarkable data source. This talk is focused on how we can detect errors and how to improve the data, from the perspective of academic researchers and but also private companies. We show the case for the Spanish DBpedia (the second DBpedia in size after the English chapter) through a set of techniques, paying attention to results and further work.

 

Clover Quiz: exploiting DBpedia to create a mobile trivia game

Clover Quiz is a turn-based multiplayer trivia game for Android devices with more than 200K multiple choice questions (in English and Spanish) about different domains generated out of DBpedia. Questions are created off-line through a data extraction pipeline and a versatile template-based mechanism. A back-end server manages the question set and the associated images, while a mobile app has been developed and released in Google Play. The game is available free of charge and has been downloaded by +10K users, answering more than 1M questions.

The Return of German DBpedia

Fabian and Tabea will present the latest news on the German DBpedia chapter as it returns to the language chapter family after an extended offline period. They will talk about the data set, discuss a few challenges along the way and give insights into future perspectives of the German chapter.

References extraction from Wikipedia infoboxes

In Wikipedia’s infoboxes some facts have references, which can be useful for checking the reliability of the provided data. We present challenges and methods connected with the metadata extraction of the Wikipedia’s sources. We used DBpedia Extraction Framework along with own extensions in Python to provide statistics about citations in 10 language versions. Provided methods can be used to verify and synchronize facts depending on the quality assessment of sources.
