Begun as a research project from the Royal Melbourne Institute of Technology and the University of Technology Dresden, WebKnox is an ontology-driven fact extraction engine built to provide direct, fast, and complete answers to questions on any topic a user can think of. To answer a question WebKnox uses external services that might have previously provided an answer or computes an answer using its knowledge base. If those options fail, WebKnox tries to find an answer on the fly.
WebKnox hosts a suite of REST APIs delivering a range of web services. The WebKnox Recipe API provides developer access to more than 100,000 recipes. The API is capable of searching or answering recipe-related questions using natural language, classifying recipes, finding similar recipes, and much more. The API can also deliver widgets for visualizing ingredients or price breakdowns, and creating recipe cards.
