ACE 2004 Multilingual Training Corpus

<h3>Introduction</h3><br>
<p>ACE 2004 Multilingual Training Corpus contains the complete set of English, Arabic and Chinese training data for the 2004 Automatic Content Extraction (ACE) technology evaluation. The corpus consists of data of various types annotated for entities and relations and was created by Linguistic Data Consortium with support from the ACE Program, with additional assistance from the DARPA TIDES (Translingual Information Detection, Extraction and Summarization) Program. This data was previously distributed as an e-corpus (LDC2004E17) to participants in the 2004 ACE evaluation.</p><br>
<p>The objective of the ACE program is to develop automatic content extraction technology to support automatic processing of human language in text form. In September 2004, sites were evaluated on system performance in six areas: Entity Detection and Recognition (EDR), Entity Mention Detection (EMD), EDR Co-reference, Relation Detection and Recognition (RDR), Relation Mention Detection (RMD), and RDR given reference entities. All tasks were evaluated in three languages: English, Chinese and Arabic.</p><br>
<p>The current publication consists of the official training data for these evaluation tasks. A seventh evaluation area, Timex Detection and Recognition, is supported by the ACE Time Normalization (TERN) 2004 English Training Data Corpus (<a href="../../../LDC2005T07">LDC2005T07</a>). The TERN corpus source data largely overlaps with the English source data contained in the current release.</p><br>

<h3>引言</h3><br>
<p>ACE 2004多语言训练语料库包含2004年自动内容抽取（Automatic Content Extraction，ACE）技术评估所需的完整英文、阿拉伯文和中文训练数据。该语料库涵盖多种类型数据，均标注了实体与关系信息，由语言数据联盟（Linguistic Data Consortium）在ACE项目支持下创建，并获美国国防高级研究计划局（DARPA）跨语言信息检测、抽取与摘要（Translingual Information Detection, Extraction and Summarization，TIDES）项目额外协助。此前，该数据曾以电子语料库（LDC2004E17）形式分发给2004年ACE评估参与者。</p><br>
<p>ACE项目的目标是开发自动内容抽取技术，支持文本形式人类语言的自动处理。2004年9月，各参与机构在六个领域接受系统性能评估：实体检测与识别（Entity Detection and Recognition，EDR）、实体提及检测（Entity Mention Detection，EMD）、EDR共指、关系检测与识别（Relation Detection and Recognition，RDR）、关系提及检测（Relation Mention Detection，RMD）及基于参考实体的RDR。所有任务均以英语、中文和阿拉伯语三种语言开展评估。</p><br>
<p>本出版物包含上述评估任务的官方训练数据。第七个评估领域——时间表达式检测与识别（Timex Detection and Recognition）——由ACE时间归一化（TERN）2004年英文训练数据语料库（LDC2005T07）提供支持，其源数据与本版本英文源数据存在大量重叠。</p><br>
