Students will get insight into the how these systems work (and why it is still so difficult to do natural language processing well). We also consider social and ethical c… text/html 2009-02-09T14:31:27-06:00 /courses/2009/spring/semisupervised_learning?rev=1234211487&do=diff Spring 2009 | Instructor: Jason Baldridge | MW 12-1:30 | PAR 10 | Blackboard The field of computational linguistics has undergone a major shift over the last two decades toward statistical methods. For some tasks, such as language modeling, there is a wealth of data available for training models, but for many tasks, the performance of models is severely limited by the amount of relevant labeled training material. Semisupervised learning seeks to use small amounts of annotated data in combinatio… text/html 2009-01-05T07:08:46-06:00 /courses/2009/spring/word_meaning_and_concepts?rev=1231160926&do=diff Spring 2009 | Instructor: Katrin Erk | Tuesday and Thursday, 11-12:30 | PAR 302 | Blackboard Word meanings are hard to characterize. There are cases in which word are systematically related and can be derived systematically, in particular through metonymy. But beyond metonymy, dictionaries do not even agree on how many senses different words have. text/html 2009-01-19T17:48:56-06:00 /courses/2009/spring/working_with_corpora?rev=1232408936&do=diff Spring 2009 | Instructor: Katrin Erk | Tuesday and Thursday, 3:30-5pm | MEZ 1.120 and PAR 10 | Blackboard Corpus linguistics is use of text corpora for exploring, documenting and modeling linguistic phenomena. This course provides a practical introduction to working with corpora.
