  • Patent number: 11431578
    Abstract: Provided are a method, apparatus, device for determining a network anomaly behavior. The method includes: acquiring network data traffic in a target network, and determining each data packet contained in the network data traffic as a node of a complete graph, to construct a data complete graph; optimizing the data complete graph into a minimum spanning tree by a Kruskal algorithm, and determining each node of the minimum spanning tree as a cluster center; classifying all data packets contained in the network data traffic based on cluster centers, to acquire data element sets corresponding to the cluster centers respectively; and determining an anomaly behavior in the target network based on a type of each of the data element sets, wherein the type of the data element set is determined by a type of a network attack contained in the network data traffic.

  • Patent number: 11164210
    Abstract: A method, a device and a computer storage medium for promotion displaying are disclosed. The method includes: using user's behavior data to perform intent recognition for the user; under the condition that an intent in a specific class is recognized, determining a target entity corresponding to the recognized intent in the specific class; expanding the recognized intent in the specific class using attribute information of the target entity; and displaying promotional data corresponding to the intent obtained from the expansion to the user. According to the technical solution, promotional data may be displayed to the user according to the user's intent, and thus the displaying efficiency and coverage rate of the promotional data may be improved.

  • Patent number: 11138381
    Abstract: A method, a computer device and a readable medium user's intent mining are disclosed. The method includes: obtaining text feature information corresponding to behavior data of a user; extracting an intent information list corresponding to the behavior data by using a pre-trained intent extracting model; and obtaining the target intent information of the user from the intent information list corresponding to the behavior data of the user, according to the text feature information and the intent information list corresponding to the behavior data, and a preset semantic similarity threshold, and adding the target intent information of the user to an intent information queue for advertisement recommendation.
