The invention discloses a cross-domain preference prediction recommendation method and
system based on personality characteristics, and the method comprises the steps: obtaining the personality
original data and historical behavior data of a user, and converting the personality
original data into personality characteristic representation; on the basis of personality feature representation, through a pre-constructed personality preference
association model, predicting the preference
score of the user for the non-contact items; generating a first recommendation
list according to the preference
score; generating a second recommendation
list according to the historical behavior data; dynamically adjusting the weights of the first recommendation
list and the second recommendation list according to the recommendation scene and
user feedback; and performing deep fusion on the first recommendation list and the second recommendation list according to the weight, and generating a final recommendation list. According to the method, through the personality preference
association model, accurate prediction and recommendation of people, information and articles which are never touched by the user but are likely to be preferred by the user are realized, and the problems of'information cocoon house 'and'
cold start' caused by the fact that a traditional recommendation method only depends on historical behaviors of the user are solved.
