Embodiment 1
[0113] as attached image 3 As shown, a method for creating a multi-dimensional feature map of a personal scene in time series, including:
[0114] Step 1: Preset the multi-level scene tag library, and preset the corresponding scene logical relationship, the calculation rules of the correlation probability between the scenes, the timing relationship between the scenes, and the chain series expression relationship. The multi-level scene tags include A first-level scene label and a multi-level subordinate scene label, the first-level scene label includes four labels of people, time, place, and weather;
[0115] Specifically, in this embodiment, the following design is made for the preset multi-level scene tag library:
[0116] 1. People are the first-level scene tags, and the corresponding tag entries are preset; it contains the second-level scene tags: gender / occupation / marriage status / age / health status / mood, and the corresponding tag entries are preset; the second-level scene...
Embodiment 2
[0144] Step 1: Preset the multi-level scene tag library, and preset the corresponding scene logical relationship, the calculation rules of the correlation probability between the scenes, the timing relationship between the scenes, and the chain series expression relationship. The multi-level scene tags include A first-level scene label and a multi-level subordinate scene label, the first-level scene label includes four labels of people, time, place, and weather;
[0145] Specifically, in this embodiment, the following design is made for the preset multi-level scene tag library:
[0146] 1. People are the first-level scene tags, and the corresponding tag entries are preset; it contains the second-level scene tags: gender / occupation / marriage status / age / health status / mood / activity, and the corresponding tag entries are preset; the second-level scene tags The doctor in contains three levels of scene tags: title / position / work unit / work address, preset corresponding tag entries, and...
Embodiment 3
[0171] The present invention also proposes an application of an automatically created personal scene map, applying the automatically created personal scene map to a personalized recommendation system, realizing user behavior prediction through the personal scene map, and realizing Personalized recommendations.
[0172] In this embodiment, the created personal scene map is stored on the server and associated with the user terminal. When the user uses a mobile terminal to perform certain operations, the system automatically obtains the scene where the user is immediately located, and obtains the corresponding scene tag value. Then match the closest personal scene from the user's personal scene map stored on the server, predict the user's behavior according to the position of this personal scene in the user's personal scene map, and realize personalized recommendation accordingly. For example, the probability that Dr. Liu goes home directly after get off work from Monday to Thurs...
