What entity linker was used

[cramraj8]

I couldn't locate any resource or link to entity linker that was used in the publication. @mickeystroller can you provide the link for it ?

The datasets used in the paper come with entities extracted from previous literature. Specifically, the S2-CS dataset is based on the dataset at http://boston.lti.cs.cmu.edu/appendices/WWW2016/ and the TREC-BIO dataset is based on PubTator annotations at https://www.ncbi.nlm.nih.gov/research/pubtator/. The entity liner details are discussed in these two papers accordingly.
