Informally, they address the following questions: (i) how precise is a kb in describing the actual world? (ii) how succinct is a kb w.r.t. the knowledge it represents? and (iii) can we increase accuracy without decreasing conciseness, or vice-versa?</p> </section> </div> </div> <div class="actions"> <form action="/Download/Pdf" id="downloadform54977" method="post"> <input type="hidden" name="id" value="54977" /> <div id='downloadlink54977' class="button getpdf">Download </div> </form> <script type="text/javascript"> $(function () { $('div#downloadlink54977').click(function () { $('form#downloadform54977').submit();
