摘要：A mechanism is provided in a computing device configured with instructions

executing on a processor of the computing device to implement a question answeringsystem for answer scoring based on a specificity score. The question answering system,executing on the processor of the computing device and configured with a questionanswering machine learning model, generates a set of candidate answers for a user-generated input question. For each given candidate answer in the set of candidateanswers, a specificity scorer of the question answering system determines a specificityvalue of each term in the given candidate answer based on a position of the term in ataxonomy data structure and determines a specificity score of the given candidate answerbased on the specificity value of the terms in the given candidate answer. The questionanswering system, determines a confidence score for each candidate answer within theset of candidate answers based on its specificity score. The question answering systemranks the set of candidate answers according to confidence score to form a ranked set ofcandidate answers and returns the ranked set of candidate answers.
