2009 CoNLL Shared Task Part 2

<h3>Introduction</h3><br>
<p>2009 CoNLL Shared Task Part 2, LDC Catalog Number LDC2012T04 and ISBN 1-58563-611-8, contains the Chinese and English trial corpora, training corpora, development and test data for the <a href="http://www.conll.org/previous-tasks" rel="nofollow">2009 CoNLL (Conference on Computational Natural Language Learning) Shared Task Evaluation</a>. The 2009 Shared Task developed syntactic dependency annotations, including the semantic dependencies model roles of both verbal and nominal predicates.</p><br>
<p>The <a href="http://www.conll.org/" rel="nofollow">Conference on Computational Natural Language Learning (CoNLL)</a> is accompanied every year by a shared task intended to promote natural language processing applications and evaluate them in a standard setting. The 2004 and 2005 CoNLL shared tasks were dedicated to semantic role labeling (SRL) in a monolingual setting (English). In 2006 and 2007, the shared tasks were devoted to the parsing of syntactic dependencies and used corpora from up to thirteen languages. In 2008, the shared task focused on English and employed a unified dependency-based formalism and merged the task of syntactic dependency parsing and the task of identifying semantic arguments and labeling them with semantic roles that data has been released by LDC as 2008 CoNLL Shared Task Data. The 2009 task extended the 2008 task to several languages (English plus Catalan, Chinese, Czech, German, Japanese and Spanish). Among the new features were comparison of time and space complexity based on participants input, and learning curve comparison for languages with large datasets.</p><br>
<p>The 2009 shared task was divided into two subtasks:</p><br>
<ul><br>
<li>parsing syntactic dependencies</li><br>
<li>identification of arguments and assignment of semantic roles for each predicate</li><br>
</ul><br>
<p>2009 CoNLL Shared Task Part 1 (<a href="http://catalog.ldc.upenn.edu/LDC2012T03" rel="nofollow">LDC2012T03</a>) contains the Catalan, Czech, German and Spanish task data and is also available through LDC.</p><br>

<p>In addition, an archive of all of the uploaded data from the participants is included in the eval-data folder. Users should note that not all data indicated in the individual READMEs is included in this release and neither are some of the corresponding DTDs for the XML. Additionally, all data is presented in its uncompressed form for ease of use. Within the user eval-data folder, the two folders marked bad contain references to data from languages included in Part 1 of this release as well as to Japanese data.

<h3>简介</h3>
<p>2009年计算自然语言学习会议（Conference on Computational Natural Language Learning，简称CoNLL）共享任务第二部分，其LDC目录编号为LDC2012T04，ISBN为1-58563-611-8，包含用于<a href="http://www.conll.org/previous-tasks" rel="nofollow">2009年CoNLL共享任务评估</a>的中英试验语料、训练语料、开发集与测试集。2009年共享任务构建了句法依存标注体系，涵盖动词与名词谓词的语义依存论元模型。</p>
<p>计算自然语言学习会议（CoNLL）每年都会配套举办共享任务，旨在推动自然语言处理应用发展，并在标准环境下对其进行评估。2004年与2005年的CoNLL共享任务专注于单语（英语）环境下的语义角色标注（Semantic Role Labeling，SRL）；2006年与2007年的共享任务聚焦于句法依存解析，使用了多达13种语言的语料库；2008年的共享任务仅针对英语，采用统一的基于依存的形式化体系，合并了句法依存解析任务与语义论元识别及标注任务，相关数据由LDC发布为《2008年CoNLL共享任务数据集》。2009年的任务将2008年的任务扩展至多语言场景：除英语外，还涵盖加泰罗尼亚语、中文、捷克语、德语、日语与西班牙语。本次任务新增的评测维度包括基于参与者输入的时空复杂度对比，以及拥有大规模语料的语言的学习曲线对比。</p>
