SubSift is a collection of tools developed in Bristol for matching academic researchers and text. It works by converting text documents to a bag-of-word representation using TF-IDF, and calculating pairwise cosine similarities. For researchers, publication titles as listed on their DBLP page are converted to BoW. A demo can be found at https://subsift-webapp.onrender.com/subsift/ (it may take 30 seconds to load the first time).
