Timely YAGO: Harvesting, Querying, and Visualizing Temporal Knowledge from Wikipedia - scientific work about Wikipedia quality published in 2010, written by Yafang Wang, Mingjie Zhu, Lizhen Qu, Marc Spaniol and Gerhard Weikum.
Overview
Recent progress in information extraction has shown how to automatically build large ontologies from high-quality sources like Wikipedia. But knowledge evolves over time; facts have associated validity intervals. Therefore, ontologies should include time as a first-class dimension. In this paper, authors introduce Timely YAGO, which extends their previously built knowledge base YAGO with temporal aspects. This prototype system extracts temporal facts from Wikipedia infoboxes, categories, and lists in articles, and integrates these into the Timely YAGO knowledge base. Authors also support querying temporal facts, by temporal predicates in a SPARQL-style language. Visualization of query results is provided in order to better understand of the dynamic nature of knowledge.
