Provided are a method and an apparatus for recommending an answer to a question based on artificial intelligence and a computer device. The method includes: receiving a query being a question; matching the query to questions having answers in a question and answer repository; calculating a semantic similarity between the query and each of the questions having answers in the question and answer repository if no question in the question and answer repository is exactly matched to the query; determining whether a question with a semantic similarity to the query greater than a preset threshold exists in the question and answer repository; if yes, recommending the answer to the question with the semantic similarity to the query greater than the preset threshold as an answer to the query.
