Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings.
[0020] see as figure 1 As shown, the technical solution adopted in this specific embodiment is: it is based on the time, frequency of occurrence, and channel dimensions that determine the subjective value of information, and through the subjective value algorithm, it screens valuable information for users and improves the efficiency of users in obtaining useful information; , the subjective value algorithm includes a time algorithm, a word segmentation algorithm (frequency coefficient α), and a channel authority algorithm (channel coefficient β); the time algorithm refers to refining the time granularity according to the release time of the content, for users to select Any time period is used as the time interval for calculating the subjective value of information; the word segmentation algorithm refers to combining the machine learning word segmentation algorithm base...

An information screening method relying on subjective values relates to the technical field of information pushing. A time algorithm is to refine the granularity of the time according to the content release time, so that a user can select any time period as the time interval to calculate the subjective value of the information. A word segmentation algorithm is a combination of machine learning algorithm based on statistics, the user input string for word segmentation, the selection of information points, and statistics of the frequency of the point. A channel authoritative algorithm refers tothe integration algorithm to calculate the number of points obtained by the user production information, as the information of the channel coefficient [beta]. Said subjective value=alpha t* beta t, wherein alpha t represents a frequency coefficient within a selected time period and beta t represents a channel coefficient within a selected time period. By referring to the frequency of information appearing in a certain time and the authoritativeness of information dissemination channel, the algorithm calculates the subjective value of the information, and recommends the information with high subjective value to the user to assist the user in learning, life and production decision-making.
Description
technical field [0001] The invention relates to the technical field of information push, in particular to an information screening method based on subjective value. Background technique [0002] Public opinion is influenced by the right to speak. In cyberspace, the right to speak is concentrated in the "priority of being read", and more specifically, the order in which information is listed, and the competition for headlines on the homepage is becoming increasingly fierce. The ranking of the information list mainly refers to the "click rate", as well as the "background intervention" of the network platform, such as "bidding ranking". [0003] This "bidding ranking" method has directly or indirectly led to the "partial eclipse" of public information consumption, and will even be used by utilitarians to forcefully push false information to the society, which is extremely harmful to the healthy and green development of cyberspace. , hindering the process of transforming the i...
