The paper introduces three chunk parsing tasks carried in current CIPS parsing evaluation workshop(CIPS-ParsEval-2009),which is organized by Tsinghua University and Northeastern University.They are base chunk parsing,functional chunk parsing and event description clause recognition tasks.The designing motivation and the classification standards of these three chunks are discussed in the paper.Based on the detailed syntactic annotations in Tsinghua Chinese Treebank(TCT),three benchmark chunk banks automatically extracted from TCT are built.The evaluation results of top-5 participating systems are also given.The data analysis from their statistics and the comparison with current chunk schemes show some characteristics of these three chunk parsing tasks.
