Embodiment

[0076] Such as figure 1 As shown, a method for judging user emotions based on browsing history and expression recognition includes the following steps:

[0077] (1) Before starting the calculation, record the different index F of its emotion for each single page to be browsed, the index F is a set value, and its content is divided into n types, and n represents n emotional states; as in this In the embodiment, n=10, and the 10 emotional states include:

[0078] 1) excitement

[0079] 2) happy

[0080] 3) sunny

[0081] 4) Calm

[0082] 5) happiness

Abstract

A method for judging the emotion of a user according to browsing history and expression recognition comprises the following steps: recording different indexes F of the emotion for a single page, wherein F can comprise n emotion states; obtaining and calculating an emotion set FP obtained by user browsing page residence time; obtaining the emotion value set FC of the number of times of repeatedly checking of browsing the page within the set time; obtaining an emotion value FE corresponding to the facial expression browsed in each single page (including repeatedly browsed); obtaining a result FWof the weather emotion state value in a specified range; obtaining results FT of the holiday emotion state values within a predetermined time range; and screening the statistical results of the n emotion states under various factors by using a decision tree method, and performing calculating to obtain the final probability distribution of the current emotion category of the user. The whole flow calculation is simple and clear and can be completed without the aid of special hardware equipment, the prediction effect is good, the requirement for data sources is simpler, and extremely high flexibility is achieved.
