  • Role-Preserving Redaction of Medical Records to Enable Ontology-Driven Processing

    Association for Computational Linguistics

    As part of a larger project involving ontology-driven medical processing, we employ a method of recognizing protected health information (PHI) that maps to ontological terms. We then use the relationships defined in the ontology to redact medical texts so that roles and semantics of terms are retained without compromising anonymity. The method is evaluated by clinical experts on several hundred medical documents, achieving up to a 98.8% f-score, and has already shown promise for retaining…

    • Based on a dictionary of words - AFINN - that have positive and negative connotations (given a positive/negative score), a tweet is given a certain positive or negative connotation based on the amount of negative/positive connotations on that tweet.
    • Words that don't have positive/negative connotations like the ones listed on the AFINN list, are given one based on their frequency of use with words that do have a positive/negative connotation on the AFINN list.
    • The frequency of each word in all the streaming tweets gathered, are outputted.

    • The "happiest" state in the US are determined based on the compounded sentiment scores of tweets for each state in the US.
