Abstract

The invention discloses a method and device for determining the preference degree of a user to an object type, and relates to the technical field of communication. A specific embodiment of the methodcomprises the steps of obtaining sample information; Wherein the sample information comprises user attributes, object types and the number of selected people of each user attribute under each object type; performing normalization calculation on the number of selected people of each user attribute under each object type to obtain the selection probability of each user attribute under each object type so as to determine the preference degree of each user attribute under each object type and generate a preference degree table; and obtaining a to-be-queried user attribute, performing query in thepreference degree table according to the to-be-queried user attribute, and determining an object type associated with the to-be-queried user attribute and a corresponding preference degree. Accordingto the embodiment, the sequencing of the recommended products is optimized according to the preference of the user attributes to the object types, the personalized recommendation method of the objecttypes is achieved, the preference of the user is met, and the efficiency of obtaining the commodity information by the user is improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for determining a user's preference for an object type. Background technique [0002] With the rapid development of network technology, people can obtain more and more information from the network, and they are more and more accustomed to using this information to assist themselves in completing various work and life matters. For example, before eating out, users often check restaurants and dishes on the Internet to decide where to eat. [0003] In order to meet the above needs of users, in some service platforms, it is often necessary to calculate the user's preference for commodity categories, so as to realize the function of recommending commodities or merchants to users according to the preference. [0004] In the prior art, commodity categories are usually sorted according to the relative pros and cons of the evaluation indicators, and combined w...
