The EventStatus Corpus

<h3>Introduction</h3><br> <p>The EventStatus Corpus was developed by researchers at <a href="https://engineering.tamu.edu/cse">Texas A&amp;M University</a>, <a href="https://linguistics.stanford.edu/">Stanford University</a> and <a href="http://www.cs.utah.edu/">The University of Utah</a>. It consists of approximately 3,000 English and 1,500 Spanish news articles about civil unrest events annotated with temporal tags.</p><br> <p>This corpus was designed to support the study of the temporal and aspectual properties of major events, that is, whether an event has already happened, is currently happening or may happen in the future. Since it focuses on a single domain (civil unrest events), it may be appropriate for tasks such as event extraction and temporal question answering.</p><br> <h3>Data</h3><br> <p>The relevant news articles were sourced from English Gigaword Fifth Edition (<a href="../../../LDC2011T07">LDC2011T07</a>) and Spanish Gigaword Third Edition (<a href="../../../LDC2011T12">LDC2011T12</a>). The civil unrest events include protests, demonstrations, marches and strikes. The data was annotated as PAST, ON-GOING or FUTURE and within each of those categories, as PLANNED, ALERT or POSSIBLE.</p><br> <p>In addition to the annotated articles, file lists used in experiments for tuning and test are included. 10-fold cross-validations were performed, and the specific 10-fold splits of the test are included as well. All text is presented as plain text and encoded in UTF-8.</p><br> <h3>Samples</h3><br> <p>Please view this <a href="desc/addenda/LDC2017T09.txt">sample</a>.</p><br> <h3>Updates</h3><br> <p>None at this time.</p></br> Portions © 1994-2010 Agence France Presse, © 1993-2010 The Associated Press, © 1997-2010 Central News Agency (Taiwan), © 1994-1998, 2003-2009 Los Angeles Times-Washington Post News Service, Inc., © 1994-2010 New York Times, © 2010 The Washington Post News Service with Bloomberg News, © 1995-2010 Xinhua News Agency, © 2017 Ruihong Huang, © 2003, 2005, 2006, 2007, 2009, 2011, 2013, 2017 Trustees of the University of Pennsylvania<h3>Introduction</h3><br> <p>事件状态语料库（EventStatus Corpus）由德克萨斯农工大学（Texas A&M University）、斯坦福大学（Stanford University）以及犹他大学（The University of Utah）的研究者开发。该语料库包含约3000篇英文新闻报道与1500篇西班牙文新闻报道，主题围绕民众动乱事件（civil unrest events），并已标注时间标签。</p><br> <p>本语料库旨在支撑针对重大事件的时间属性与体特征的研究，即判断某一事件是否已发生、正在进行或将在未来发生。由于其聚焦于单一领域（民众动乱事件），该语料库适用于事件抽取、时序问答等相关任务。</p><br> <h3>Data</h3><br> <p>相关新闻报道来源于英文巨无霸语料库第五版（English Gigaword Fifth Edition，编号LDC2011T07）与西班牙文巨无霸语料库第三版（Spanish Gigaword Third Edition，编号LDC2011T12）。民众动乱事件涵盖抗议活动、示威集会、游行与罢工行动。数据被标注为已发生（PAST）、进行中（ON-GOING）或未来将发生（FUTURE），且在每个大类下进一步细分为已筹划（PLANNED）、已预警（ALERT）或潜在可能（POSSIBLE）。</p><br> <p>除标注完成的新闻报道外，本数据集还包含实验中用于调参与测试的文件列表。本数据集开展了10折交叉验证（10-fold cross-validations）实验，并附带测试集的具体10折划分方案。所有文本均以纯文本形式呈现，编码格式为UTF-8。</p><br> <h3>Samples</h3><br> <p>请查看<a href="desc/addenda/LDC2017T09.txt">示例文件</a>。</p><br> <h3>Updates</h3><br> <p>暂无更新记录。</p></br> Portions © 1994-2010 法新社（Agence France Presse）、© 1993-2010 美联社（The Associated Press）、© 1997-2010 中央通讯社（中国台湾，Central News Agency (Taiwan)）、© 1994-1998、2003-2009 洛杉矶时报-华盛顿邮报新闻服务公司（Los Angeles Times-Washington Post News Service, Inc.）、© 1994-2010 《纽约时报》（New York Times）、© 2010 彭博新闻旗下华盛顿邮报新闻服务（The Washington Post News Service with Bloomberg News）、© 1995-2010 新华通讯社（Xinhua News Agency）、© 2017 黄瑞红（Ruihong Huang）、© 2003、2005、2006、2007、2009、2011、2013、2017 宾夕法尼亚大学理事会（Trustees of the University of Pennsylvania）
