<br>..............................<div>...................<br><br>Recent years have shown an increased interest in bringing the field of<br>graph theory into Natural Language Processing. In many NLP
<br>applications entities can be naturally represented as nodes in a graph<br>and relations between them can be represented as edges. Recent<br>research has shown that graph-based representations of linguistic<br>units as diverse as words, sentences and documents give rise to novel
<br>and efficient solutions in a variety of NLP tasks, ranging from part<br>of speech tagging, word sense disambiguation and parsing to<br>information extraction, semantic role assignment, summarization and<br>sentiment analysis.
<br><br>This workshop builds on the success of the first TextGraphs workshop<br>at HLT-NAACL 2006. The aim of this workshop is to bring together<br>researchers working on problems related to the use of graph-based algorithms for natural
<br>language processing and on the theory of graph-based methods.<br>It will address a broader spectrum of research areas to foster<br>exchange of ideas and help to identify principles of using the graph<br>notions that go beyond an ad-hoc usage. Unveiling these principles will give rise to applying generic graph
<br>methods to many new problems that can be encoded in this framework.<br><br>We invite submissions of papers on graph-based methods applied to<br>NLP-related problems. Topics include, but are not limited to:<br><br>- Graph representations for ontology learning and word sense disambiguation
<br>- Graph algorithms for Information Retrieval, text mining and understanding<br>- Graph matching for Information Extraction<br>- Random walk graph methods and Spectral graph clustering<br>- Graph labeling and edge labeling for semantic representations
<br>- Encoding semantic distances in graphs<br>- Ranking algorithms based on graphs<br>- Small world graphs in natural language<br>- Semi-supervised graph-based methods<br>- Statistical network analysis and methods for NLP
<br><br>Submission format:<br><br>Submissions will consist of regular full papers of max. 8 pages and<br>short papers of max. 4 pages, formatted following the NAACL 2007<br>guidelines. Papers should be submitted using the online submission
