Abstract

The embodiment of the invention discloses a user interest model updating method and device. A user interest model is represented through a concept hierarchy tree. The concept hierarchy tree comprises interest clusters, interest categories and interest keywords from the high concept hierarchy to the lower concept hierarchy, wherein one or more interest keywords belong to the same interest category, and one or more interest categories belong to the same interest cluster. The method comprises the steps that a user operation behavior is converted into a text, and interest keywords are extracted from the text; the interest keywords are clustered to obtain at least one interest category; the concept hierarchy tree is updated by using the interest category obtained through clustering. It shows that the interest keywords are extracted from the user operation behavior, the newly-added messages (the interest keywords) are clustered, and the newly-added messages do not exist in the user interest model in disorder. Even if the multiple newly-added messages exist, the number of the categories obtained through clustering is much smaller than the number of the newly-added messages, and therefore the influence on the user interest expression accuracy can be lowered.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a user interest model updating method and a related device. Background technique [0002] The user recommendation device can automatically recommend recommended information such as websites, articles, news, commodities, etc. that may be of interest to the user. The recommendation process of user recommendation devices in the current communication field (eg, data analysis platform, push platform) generally includes three stages: user modeling, item matching and recommendation output. Among them, user interest modeling determines the success rate of recommendation to a large extent; user interest modeling is the process of acquiring and maintaining knowledge related to user interests, needs or habits, and the result will produce a model that represents the user's unique interests and needs. user interest model. [0003] When user interest changes, the user interest model a...
