5. The information query method as claimed in claim 4, wherein the step of acquiring the user ID updated asset information from the corresponding information terminal according to the intersection user ID further comprises:
and the account center acquires the asset information updated by the user ID from the corresponding information terminal according to the browsing behavior data or/and the clicking behavior data of the user ID in the intersection.
6. The information query method as claimed in claim 4, wherein before the step of the account center acquiring the asset information updated by the user ID from the corresponding information terminal according to the user ID in the intersection, the method further comprises:
and a step of performing data cleaning on the browsing behavior data and the clicking behavior data, and removing invalid behavior records from the behavior data.
7. An electronic device comprising a memory and a processor, wherein the memory stores an information query program, and the information query program when executed by the processor performs the steps of:
an account center is established, and the account center is in wireless connection with a plurality of information terminals, wherein the account center stores accounts of the information terminals, and the accounts comprise user IDs and asset information used by the user IDs;
when the account of any information terminal changes, the account center stores the user ID into a message queue;
constructing an active user list according to the user liveness;
acquiring an intersection user of the active user list and the message queue;
acquiring asset information updated by the user ID from a corresponding information terminal according to the intersection user ID; wherein, include:
forming behavior sequences by browsing behavior data or/and clicking behavior data of users in the intersection, wherein the behavior sequences are time sequences which are ordered by various asset information identifiers according to behavior occurrence time;
dividing the behavior sequence into a plurality of first sub-sequences with at least one sequence length, the sequence length of the first sub-sequences being shorter than the sequence length of the behavior sequence;
constructing a tree of behavior sequences according to the first subsequence; wherein the step of constructing a tree of behavior sequences from the first subsequence comprises: taking each asset information identifier appearing in the behavior sequence as a root node, taking various asset information identifier combinations in the first subsequence as branches, forming each subtree by each branch of each root node connected with the root node, wherein the asset information identifier Fu Zaihang represented by the root node is a node value of the root node, the number of occurrences in the sequence of the asset information identifiers represented by the root node is the node value of the child node, and the sum of the number of occurrences in each first subsequence of the asset information identifier combinations represented by the root node to the child node is the node value of the child node;
combining the asset information identifier represented by the root node of each branch of the subtree of the behavior sequence tree with the asset information identifier represented by the child nodes except the bottom child node to form a plurality of second subsequences with different sequence lengths according to the layer sequence;
obtaining the predicted probability that the asset information identifier of the next order of each second sub-sequence is any asset information identifier in the behavior sequence;
ordering the second subsequence and a third subsequence consisting of asset information identifiers of a next order according to the order of the prediction probability from high to low;
screening out a third subsequence comprising the maximum prediction probability of the last asset information identifier of the user behavior sequence, thereby obtaining the asset information identifier of the next order of the last asset information identifier, and updating the asset information corresponding to the asset information identifier of the next order of the user.
8. A computer-readable storage medium, wherein an information inquiry program is included in the computer-readable storage medium, which when executed by a processor, implements the steps of the information inquiry method according to any one of claims 1 to 6.
