title: What tools can perform automatic relation extraction without any configuration or coding?
body: <p>I have designed a system to do automatic relation extraction on a specific corpus, where the relations are not known in advance. I want to compare my system to another system that does <a href="http://reverb.cs.washington.edu/" rel="nofollow">automatic relation extraction</a> to see if my system performs any better (for an academic thesis). The only such automatic extraction system that I know about is reverb. </p>
  
  <p>In the readme for the <a href="http://reverb.cs.washington.edu/" rel="nofollow">reverb</a> system they say that reverb is "is designed for Web-scale information extraction, where the target relations cannot be specified in advance and speed is important." My system is much slower than reverb (I think because it parses sentences and performs deeper analysis) so I am not sure if the comparison is meaningful. I extract more relations but the comparison is a little unfair (because my system is so much more computationally intensive). Are there other systems like reverb that can do automatic relation extraction? Maybe systems that are not "designed for web-scale information extraction" that are more fair competitors?</p>
  
  <p>I know NLTK does relation extraction but you have to supply a specific regex glue to bind entities in a relation. </p>
  
  <p>Are there other tools out there that NLP practitioners use to do automatic relation extraction?</p>
