At the École normale supérieure de Lyon we have to do a programming project during the first part of your master degree curriculum. Some of us were very interested in working on natural language processing and others on knowledge bases. So, we tried to find a project that could allow us to work on both sides and, quickly, the idea of an open source question answering tool came up.
This tool has to answer to a lot of different questions so one of the requirements of this project was to use a huge generalist knowledge base in order to have a usable tool quickly. As one of us was already a Wikidata contributor and inspired by the example of the very nice but ephemeral Wiri tool of Magnus Manske, we quickly chose to use Wikidata as our primary data source.
This is why, after four months of hard work from seven people, we are happy to introduce Platypus, the new English speaking interface for Wikidata.
