Growing Wikipedia Across Languages via Recommendations

Leila Zia, Research Scientist, Wikimedia Foundation

3/15/2017

12:00pm - 1:00pm

Location: 310, Banatao Auditorium, Sutardja Dai Hall

Leila Zia joined the Wikimedia Foundation in February 2014 as part of the Research and Data team. She received her PhD from Stanford University in Management Science and Engineering. Her current research interests are on understanding Wikipedia's readers, quantifying and addressing the gaps of knowledge in Wikipedia and Wikidata, and understanding contributor diversity and its challenges in Wikipedia.

The different Wikipedia language editions vary dramatically in how comprehensive they are. I present past and ongoing research projects that help editors grow Wikipedia across languages. In the first part of the talk I present an approach to filling gaps in article coverage across different Wikipedia editions. The main contribution of this work is an end-to-end system for recommending articles for creation that exist in one language but are missing in another. The system involves identifying missing articles, ranking the missing articles according to their importance, and recommending important missing articles to editors based on their interests. I show the result of empirical validation of the models in a controlled experiment involving 12,000 Wikipedia editors.
