Appendix 6: Error Tables

The tables in this appendix show the errors which occurred for English with isometric tagging of the Brown Corpus, with RTP weight set to 30%, and without RASs. The first group of tables shows the frequencies with which particular correct tags were missed. The second group shows the frequencies with which particular tags were assigned when they should not have bee. Finally, the third group of tables shows the frequencies of each error pair (an actual tag and an assigned but erroneous tag).
