<h3>Introduction</h3><br>
<p>2015-2016 CoNLL Shared Task, LDC Catalog Number LDC2017T13 and ISBN 1-58563-812-9, contains the Chinese and English training, development and test data for the <a href="http://cs.brandeis.edu/~clp/conll15st">2015</a> and <a href="http://www.cs.brandeis.edu/~clp/conll16st/">2016</a> CoNLL (Conference on Computational Natural Language Learning) Shared Task Evaluation which focused on shallow discourse parsing.</p><br>
<p>The <a href="http://www.conll.org/">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. Shallow discourse parsing is the task of parsing a piece of text into a set of discourse relations between two adjacent or non-adjacent discourse units. This task is called shallow discourse parsing because the relations in a text are not connected to one another to form a connected structure in the form of a tree or graph.</p><br>
