Problems solved by technology
After analysis, the inventor found that the static user modeling method can only give a rough description of the user's interests, and there are some problems in practical applications. First, because this user model is static, the user's interest described by the model is only It is valid for a certain period of time and cannot reflect changes in user interests in the future; secondly, the personal information submitted by users is a subjective input and cannot objectively reflect the characteristics of their interests
[0006] Dynamic user modeling analyzes user activities and behaviors on the website. After analysis, the inventor found that the description granularity of the user model is very small, and there is no general description for a specific point of interest.
[0007] In addition, there are other user modeling methods that require the user to provide feedback information, which will complicate the user's operation and affect the user's normal behavior

Embodiment Construction
[0055] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0056] like figure 1 As shown, in the embodiment of the present invention, the process of providing target information to the user is as follows:
[0057] Step 11. Obtain the historical behavior data of the user's browsing information, the historical behavior data including information content and browsing time.
[0058] Step 12, classify the content of the information, and obtain the probability that the information belongs to the set category.
[0059]Step 13. Obtain the user's interest value at the set time according to the obtained probability and the browsing time.
[0060] Step 14, according to the interest value, provide target information to the user at a set time.
[0061] figure 1 In the flow shown, the information browsed by the user may be a website, a webpage, or an object in the webpage, which may be set according to user requirements...

The invention discloses a method for providing target information to users. The method includes: obtaining historical behavior data of users browsing information, the historical behavior data including information content and browsing time; classifying the information content, And determine the probability that the information belongs to one or more categories to which the content belongs according to the classification results; determine the user's interest in the one or more categories at the set time according to the probability and the browsing time value; according to the interest value, provide the user with the target information of the category corresponding to the interest value not less than the set threshold at the set moment. The invention also discloses a device for providing target information to users. The invention can quantify and describe the user's interest in information in multiple granularities according to the user's demand, dynamically reflect the changing process of the user's interest, and simplify the user's operation.
Description
technical field [0001] The invention relates to the field of network technology, in particular to a method and equipment for providing target information to users. Background technique [0002] There is a huge amount of information on the Internet, which is rich in content and in various forms. Internet users hope to obtain information that meets their personal needs from the vast information resources. Search engines, metasearch engines, and other search tools help us extract information from the vast web of information. When a user performs a search, generally only a few search keywords are provided, while a search engine returns a huge number of search results. If there is no analysis of user interests, that is, if no accurate user model is established, users will be submerged in the ocean of information. [0003] It can be seen that establishing an accurate user model is very important for obtaining user target information. User modeling has become the core research ...
