Coordination Annotation for the Penn Treebank

<h3>Introduction</h3><br>
<p>Coordination Annotation for the Penn Treebank&nbsp;is a stand-off annotation for the Wall Street Journal portion of Treebank-3 (PTB3) (<a href="../../../LDC99T42">LDC99T42</a>) developed by researchers at the <a href="http://www.uni-duesseldorf.de/home/en/home.html">University of D&uuml;sseldorf</a> and <a href="http://www.iub.edu/">Indiana University</a>. It marks all tokens that have a coordinating function (potentially among other functions).</p><br>
<p>Coordination is a syntactic structure that links together two or more elements known as conjuncts or conjoins. The presence of coordination is often signaled by the appearance of a coordinator (coordinating conjunction), such as <em>and</em>, <em>or</em>, <em>but</em> in English.</p><br>
<p>Penn Coordination Annotation is available at no cost to all licensees of <a href="../../../LDC99T42">PTB3</a> and appears in their download queue associated with LDC99T42 as <em>penn_coordination_anno_LDC2015T08.tgz</em>.</p><br>

<h3>简介</h3><br>
<p>宾夕法尼亚树库（Penn Treebank, PTB）并列结构标注是针对树库3（Treebank-3, PTB3）中《华尔街日报》语料部分的分离式标注（stand-off annotation），由<a href="http://www.uni-duesseldorf.de/home/en/home.html">杜塞尔多夫大学</a>与<a href="http://www.iub.edu/">印第安纳大学</a>的研究人员为<a href="../../../LDC99T42">LDC99T42</a>语料库开发。该标注会标记所有承担并列功能（也可同时兼具其他功能）的Token。</p><br>
<p>并列结构是一种句法结构，用于连接两个及以上被称为并列项（conjuncts/conjoins）的成分。在英语中，并列结构通常由并列连词（coordinator，即coordinating conjunction）标识，例如<em>and</em>、<em>or</em>、<em>but</em>。</p><br>
<p>宾夕法尼亚并列结构标注集对所有获得树库3（PTB3）授权的使用者免费开放，其以<em>penn_coordination_anno_LDC2015T08.tgz</em>的文件名出现在与<a href="../../../LDC99T42">LDC99T42</a>绑定的下载队列中。</p><br>
<h3>数据</h3><br>
<p>该标注集以单个UTF-8编码的纯文本TSV文件格式提供，各列含义如下：</p><br>
<ul><br>
<li>section：宾夕法尼亚树库《华尔街日报》语料的章节编号</li><br>
<li>file：章节内的文件编号</li><br>
<li>sentence：句子编号（从0开始计数）</li><br>
<li>token：Token编号（从0开始计数）</li><br>
<li>annotation：若该Token为并列标点则标注为"P"，否则标注为"O"</li><br>
</ul><br>
