NAACL HLT 2007 Workshop: TextGraphs-2: Graph-based Methods for Natural Language Processing In many NLP applications entities can be naturally represented as nodes in a graph and relations between them can be represented as edges. Recent research has shown that graph-based representations of linguistic units as diverse as words, sentences and documents give rise to novel and efficient solutions in a variety of NLP tasks. This workshop focuses on graph-based algorithms for natural language processing and on the theory of graph-based methods. Organizers: Chris Biemann, University of Leipzig Irina Matveeva, University of Chicago Rada Mihalcea, University of North Texas Dragomir Radev, University of Michigan Full paper submissions due: January 29 Short paper submissions due: February 4 Workshop Home Page: http://www.textgraphs.org/ws07
