October 2005 Best Paper Award to LOGON Generation Component

At the Second International Joint Conference on Natural Language Processing, John Carroll and Stephan Oepen receive the IJCNLP Best Paper award for their joint work on the LOGON generation component. Their paper High-Efficiency Realization for a Wide-Coverage Unification Grammar reviews a series of novel algorithmic contributions to chart generation, defines a procedure for selective enumeration of n-best results, and presents an in-depth empirical evaluation. IJCNLP 2005 was a highly competitive conference this year, accepting just above thirty per cent of the nearly 300 submissions that were received. Congratulations, John and Stephan!
