Method and device for extracting points of interest, terminal equipment and storage medium

The invention provides an interest point extraction method and device, terminal equipment and a storage medium. According to the technical scheme, target use data of the terminal equipment in a target time period are obtained, and the target use data comprise use data of at least one APP in the target time period, description data of the at least one APP and state data comprising screen turn-on information and screen turn-off information of the terminal equipment; then vectorizing the target use data, and carrying out similarity calculation on the vectorized target use data and a plurality of preset vectorized data to determine target vectorized data; and finally, determining a preset interest point corresponding to the target vectorized data as a target interest point of the target time period. According to the method for extracting the interest points, the interest points of the user in a certain period of time can be accurately perceived on the premise that the user does not need to actively inform the int
