and translate them to precise symbolic forms, without resorting to imprecise meaning-independent statistical methods.</p> <h5 class="orange">Learning from Users</h5> <p>The high performance of today's Wolfram NLU has been achieved partly through analysis of billions of user queries in Wolfram|Alpha.</p> </div> <div class="twocol_two"> <h5 class="orange">Knowledge-Based Disambiguation</h5> <p>Wolfram NLU routinely combines outside information like a user's geolocation, or conversational context with its built-in knowledgebase to achieve extremely high success rates in disambiguating

sometimes informed by statistical studies of the content of the web.</p> <h5 class="orange">Understanding Raw Human Thoughts</h5> <p>Wolfram NLU is set up not only to take input from written and spoken sources, but also to handle the more "stream-of-consciousness" forms that people type into input fields.</p> <h5 class="orange">Powered by the Cloud</h5> <p>Wolfram NLU and its large
