Abstract
Systems and methods for identifying an adverse effect of a pharmaceutical substance are provided. A system may tokenize an electronic medical record for a plurality of tokens. The system may further generate a distance score between a first vector of a word embedding model and a second vector of the word embedding model. The first vector may correspond to a substance token and the second vector may correspond to a condition token. The system may further detect an absence of a preventative association between the substance token and the condition token in a prevention repository. The system may further generate a causal link indication indicative of a causal link between the substance token and the condition token in response to the distance score being greater than a threshold value and detection of the absence of the preventative association between the substance token and the condition token.
