<p>I&#39;m trying to perform a thorough review of Hi-C and RNAi developments and have found myself looking at publication A (2011) and publication B (2015). B doesn&#39;t cite A explicitly but I&#39;m sure there are papers linking the two and I&#39;d like to find them. Are there existing utilities to help with this? I&#39;ve used <a href="http://www.ncbi.nlm.nih.gov/home/api.shtml">NCBI E-utilities</a> in the past but would prefer not to rewrite an application that already exists.</p>

<p>I played with neo4j and pubmed in 2010: http://plindenbaum.blogspot.fr/2010/02/path-from-egonwillighagen-to-jandot.html but it required to load a bunch of articles.</p>
