Document Type and Number:
Japanese Patent JP6643554
Kind Code:
B2
Abstract:
Embodiments of the present disclosure disclose a method and apparatus for recommending entity. A method for recommending entity includes: acquiring a candidate entity set associated with a to-be-searched entity, in response to receiving a user's search request for an entity; inputting the candidate entity set into a pre-trained ranking model to obtain a candidate entity sequence; and selecting a candidate entity from the candidate entity sequence and recommending the selected candidate entity to the user. The ranking model ranks the candidate entity set based on at least one of: a degree of correlation between each candidate entity in the candidate entity set and the to-be-searched entity; a degree of interest of the user in the each candidate entity in the candidate entity set; and a degree of expectation of the user for the each candidate entity in the candidate entity set. This embodiment achieves a more relevant, individualized, surprising, and diversified entity recommendation for the user and/or the to-be-searched entity.
