... to avoid error propagation and make use of POS information for word segmentation, segmen- tation and POS tagging can be viewed as a single task: given a raw Chinese input sentence, the joint POS ... language modeling and utterance classifica- tion (Saraclar and Roark, 2005) and labeling and chunking (Shimizu and Haas, 2006). Though our model is built specifically...

... not an easy task because segmentation and POS tagging standards vary, and our test data have not been used for a final evaluation before. Nev- ertheless, there are of course systems that perform word ... segmentation and POS tagging analysis to the parser proper or they are character-based, i.e. segmentation and tagging are part of the parsing process. Although seve...

The numbers are very high: an F-measure of about 88.8% for the gold segmentation and tagging, and about 82.8% for gold segmentation only. Thi...
