该文主要介绍了目前中文信息学会句法分析评测CIPS-ParsEval-2009中的三项块分析评测任务:基本块分析、功能块分析和事件描述小句识别的设计理念、判定标准和相关资源构建方法。然后给出了这三项目前的主要评测结果并对相关内容进行了简要分析。最后通过相关统计数据分析和国内外相关研究评述,总结了这三项评测任务的主要特色。
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 an- notations 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.
