Title:LingPipe: Architecture and Algorithms

Time:Thursday October 30, 11:30 - 12:30

Place:CS Conference Room in MUDD

Abstract: I will discuss the architecture, algorithms and performance of our open-source natural language software, LingPipe. LingPipe provides trainable named-entity, sentence detection and within-document coreference. I'll detail the statistical models, data structures, decoder, and I/O integration that support training and testing on multilingual data. Performance of version 1.0 is 100K words/second for named-entity detection with an F score of .93 on MUC7 data trained without any gazetteers or other dictionaries.
