PURPOSE: Keyword recommendation apparatus and method thereof are provided to recommend an optimal keyword to a user by calculating a weighted value for a candidate keyword based on an evolutionary algorithm. CONSTITUTION: A candidate keyword configuration unit (110) uses keyword groups related to a document or a user and configures candidate keywords for the document. An importance calculation unit (120) calculates an importance value of a feature vector for the candidate keywords. A weighted value calculation unit (130) uses evolution algorithm based on a configured evaluation criterion and calculates a weighted value of the feature vectors. A recommended keyword determination unit (140) determines a candidate keyword having the weighted value given to an importance value of the feature vectors in the candidate keywords as a recommended keyword.
