We are currentlybuilding a new conceptual sentence analyzer called Sundance (SentenceUNDerstanding ANd Concept Extraction). <dt> <h3> <!WA2><a href="http://www.cs.utah.edu/projects/nlp/autoslog.html"><!WA3><img src = "http://www.cs.utah.edu/projects/nlp/ball.pink.gif"> Automated Dictionary Construction </a> </h3><dd> We have developed the AutoSlog dictionary construction systemthat generates dictionaries of extraction patterns automatically usingan annotated corpus. We are currently working with a new version,AutoSlog-TS, that does <i> not </i> require text annotations butsimply preclassified texts instead. <dt> <h3> <!WA4><a href="http://www.cs.utah.edu/projects/nlp/signatures.html"><!WA5><img src = "http://www.cs.utah.edu/projects/nlp/ball.pink.gif"> Text Categorization </a> </h3><dd> Our approach to text classification an underlying informationextraction system to recognize linguisic context in order to achievehigh precision. We have developed several algorithms fortext classification, including the relevancy signatures algorithm, theaugmented relevency signatures algorithm, and a case-basedclassification algorithm. <dt> <h3> <!WA6><a href="http://www.cs.utah.edu/projects/ursa"><!WA7><img src = "http://www.cs.utah.edu/projects/nlp/ball.pink.gif"> Information Retrieval </a> </h3><dd> The URSA (Utah Retrieval System Architecture) Project has beenongoing at Utah for many years and involves building query-based retrievalengines and text browsers. </dl> <hr> <h2> Cast of Characters </h2> <h3><pre><i>Faculty: </i><!WA8><a href="http://www.cs.utah.edu/~riloff">Ellen Riloff</a>, The Queen of Slog<i></i> <!WA9><a href="http://www.cs.utah.edu/~hollaar">Lee Hollaar</a>, Washington Correspondent<i>Staff:</i> <!WA10><a href="http://www.cs.utah.edu/~elens">Robert Elens</a>, Pif God<i>Students:</i> <!WA11><a href="http://www.cs.utah.edu/~bean">David Bean</a>, Chief Parrothead<i></i> <!WA12><a href="http://www.cs.utah.edu/~jlorenz">Jeff "Crash" Lorenzen</a><i></i> <!WA13><a href="http://www.cs.utah.edu/~kjmason">Kem "Kareem" Mason</a><i></i> <!WA14><a href="http://www.cs.utah.edu/~pnielson">Paul Nielson</a>, Newlywed<i></i> <!WA15><a href="http://www.cs.utah.edu/~msalem">Mark Salem</a>, Virtual Student<i></i> <!WA16><a href="http://www.cs.utah.edu/~jshepher">Jessica Shepherd</a><i></i> <!WA17><a href="http://www.cs.utah.edu/~wkiri/">Kiri Wagstaff</a></pre> </h3> <br><h2> <!-- <!WA18><a href="http://www.cs.utah.edu/projects/nlp/links.html"></a>Related Pages and --><!WA19><a href="http://www.cs.utah.edu/csinfo/slc_utah.html">About SLC and Utah</a> </h2><hr><center><!WA20><a href="http://www.cs.utah.edu/"><!WA21><img border=0 src="http://www.cs.utah.edu/projects/icons/dept_cs_button.gif"></a><!WA22><a href="http://www.cs.utah.edu/projects/nlp/"><!WA23><img src="http://www.cs.utah.edu/projects/nlp/nlp+ir.xbm"></a><!WA24><a href="http://www.cs.utah.edu/projects/"><!WA25><img border=0 src="http://www.cs.utah.edu/projects/icons/research_cs_button.gif"></a></center><hr>Mail: <i><!WA26><a href="mailto:riloff@cs.utah.edu">riloff@cs.utah.edu</a></i>for more information.<br><!-- hhmts start -->Last modified: Thu Nov 23 08:14:37 1995<!-- hhmts end --></body> </html>⌨️ 快捷键说明
