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 Search API allows applications and websites to perform web, image, and news searches. The API provides the option to limit the number of results or skip a specified number of top results.
