title: SDP 2014 & 2015: Broad Coverage Semantic Dependency Parsing

description: <h3>Introduction</h3><br>
<p>SDP 2014 & 2015: Broad Coverage Semantic Dependency Parsing consists of data, tools, system results, and publications associated with the 2014 and 2015 tasks on Broad-Coverage Semantic Dependency Parsing (<a href="http://sdp.delph-in.net/">SDP</a>) conducted in conjunction with the International Workshop on Semantic Evaluation (<a href="http://alt.qcri.org/semeval2015/">SemEval</a>) and was developed by the SDP task organizers.</p><br>
<p>SemEval is an ongoing series of evaluations of computational semantic analysis systems intended to explore the nature of meaning in language. It evolved from the <a href="http://www.senseval.org/">Senseval</a> word sense disambiguation series to include semantic analysis tasks outside of word sense disambiguation.</p><br>
<h3>Data</h3><br>
<p>SDP 2014 & 2015: Broad Coverage Semantic Dependency Parsing is based on English, Chinese and Czech data from the following resources: Treebank-2 <a href="../../../LDC95T7">LDC95T17</a>, Proposition Bank I <a href="../../../LDC2004T14">LDC2004T14</a>, NomBank v 1.0 <a href="../../../LDC2008T23">LDC2008T23</a> and CCGBank <a href="../../../LDC2005T13">LDC2005T13 </a> (English); Chinese Treebank (e.g., Chinese Treebank 8.0 <a href="../../../LDC2013T21">LDC2013T21</a>) (Chinese); and Prague Dependency Treebank (e.g., Prague Dependency Treebank 2.0, <a href="../../../LDC2006T01">LDC2006T01</a>) (Czech).</p><br>
<p>The results are presented as graphs in three target representations: MRS-Derived Semantic Dependencies (DM), Enju Predicate&ndash;Argument Structures (PAS), and Prague Semantic Dependencies (PSD). As a fourth, additional target representation CCGbank was converted to semantic dependency graphs (in the subdirectory &lsquo;ccd&rsquo;). These graphs are aligned with the graphs released in connection with SDP 2015 for English.</p><br>
<p>The data is divided into three main directories:</p><br>
<ul><br>
<li>&lsquo;2014/&rsquo; &mdash; the data, tools, and system results from Task 8 at SemEval 2014</li><br>
<li>&lsquo;2015/&rsquo; &mdash; the data, tools, and system results from Task 18 at SemEval 2015</li><br>
<li>&lsquo;ccd/&rsquo; &mdash; the new set of semantic dependency graphs derived from CCGbank</li><br>
</ul><br>
<p>In the 2014 and 2015 sub-directories, the file layout preserves the original conventions used for data distribution to SemEval participants, so as to make it easy to replicate published results. Each sub-directory (including the new &lsquo;ccd/&rsquo;) provides its own file &lsquo;README.txt&rsquo; with additional instructions.</p><br>
