Overview of the network method for estimating ADR severity from word embeddings. Word embeddings for 28,113 ADR terms and phrases were extracted from the RedMed word-embedding model. A network is constructed based on nearest-neighbors in the embedding space. A subset of nodes is labeled as severe or benign ADRs, and random walks from these labeled nodes are conducted. The Severity of Adverse Events Derived from Reddit scores for each ADR are calculated based on the relative number of encounters in random walks initiated from severe versus benign nodes. ADR: adverse drug reaction.
