The method includes obtaining a user intention list including at least one user intention; separating the user intention into a plurality of tasks; and creating a task flow graph for the plurality of tasks based on user usage data. Each vertex in the task flow graph represents a task and indicating an importance of the task. The method also includes creating a func flow graph based on the user usage data and temporal sequences of the tasks and funcs, and each vertex in the func flow graph represents a func and indicating an importance of the func.

Abstract: A method for scalable user intent mining is provided. The method includes detecting named entities from a plurality of query logs in a public query log dataset and generating features of the plurality of query logs based on the detected named entities. The method also includes applying a multimodal restricted boltzmann machine (RBM) on the generated features of the plurality of query logs to train a public multimodal RBM and generating a plurality of public query representations. Further, the method includes receiving a search query from a user, determining whether there are a plurality of history queries of the user. When there is no history query, user intent is predicted using the public multimodal RBM. When there are the history queries, the public multimodal RBM is applied on the plurality of history queries to train a personalized multimodal RBM, and the user intent is predicted using the personalized multimodal RBM.

Abstract: The present invention provides a method for classifying media access control (MAC) address based on an Ethernet ring network, and the method comprises: when the Ethernet ring network is carrying out initialization, a node of the ring classifies the MAC address corresponding to a non-ring port in its own forward database (FDB) into a MAC address group, and takes its own MAC address as the index of the MAC address group. A node of the ring broadcasts a message carrying the MAC address group indexed by its own MAC address in the Ethernet ring network; the node of the ring receiving the message completes the classification of the MAC address corresponding to the ring port in its own FDB by adding the MAC address group carried by the message into its own FDB. The present invention also provides a device for classifying media access control (MAC) address based on Ethernet ring network.

Abstract: The disclosure provides a protection switching method for an Ethernet dual-homed link, which comprises: a node on one path of a dual-homed link detects that a failure occurs in a link or node which is directly connected with the node per se; when the node which detects the failure is a non-master node, the non-master node continuously transmits N failure state protocol (SF) messages outwards through a non-failed port on the failure path; after receiving the SF messages, the master node switches traffic on the failure path to an available path. The disclosure further provides another protection switching method for an Ethernet dual-homed link and a protection switching system for an Ethernet dual-homed link. By means of the disclosure, when a failure occurs in a link or node, a fast protection switching for the Ethernet dual-homed link can be realized; moreover, when the link or node recovers from the failure, a fast backward switching for the Ethernet dual-homed link can be realized as required actually.

Abstract: The present invention discloses a method for controlling failure recovery of Ethernet loop protection and an Ethernet loop node. The method comprises: when a node adjacent to a failed link detects recovery of the link, blocking a port just recovered, setting the port to be in a pre-forwarding state and starting a timer, and releasing the port temporarily blocked if the node adjacent to the failed link has not received a control protocol message sent by a master node during a timing period of the timer, and transferring the port from the pre-forwarding state to a forwarding state. The present invention allows a port of a node adjacent to a recovered link to enter into a forwarding state from the pre-forwarding state as early as possible on the premise that a corresponding control protocol message is unable to be received in time.
