2results about How to "Improve clustering efficiency" patented technology

This application discloses a method, apparatus, device, and medium for event aggregation based on feature association, relating to the field of text classification and analysis. The method includes: acquiring multiple event texts to be aggregated and multiple historical event clusters; wherein each event text includes a title and a summary; based on single-pass clustering, clustering is performed on the title and summary respectively, using multiple historical event clusters, to determine the title identifier and summary identifier of each event text; traversing all summary identifiers, processing each event text to obtain multiple aggregated event clusters; wherein in each round of traversal, event texts are selected based on the current summary identifier to construct the current event set, and the current event set is updated according to the title identifiers of all event texts in the current event set to obtain the aggregated event clusters; and the historical event clusters and aggregated event clusters are merged and updated according to the title identifier and summary identifier to complete the event aggregation. Implementation of this application can improve the accuracy of event aggregation.

The present disclosure provides a node clustering method and device, electronic equipment and storage medium, the method comprising: determining a plurality of routing paths according to the calling relationship between a plurality of network nodes; determining a starting node and its belonging node hierarchy from the plurality of network nodes; traversing each routing path starting from the starting node; when traversing the current routing path, determining the hierarchy of each node according to the distance between each network node and the starting node and the hierarchy of the starting node; if the hierarchy of the next node of the current node has been determined, ending the traversal and recording the path traversal result; when the traversal of the plurality of routing paths is completed, clustering the network nodes at the same hierarchy into the same cluster node group according to all the results. The method clusters the network nodes according to the data flow direction in the network, and sets the traversal end condition, which can solve the problem that node clustering cannot be achieved in the presence of a loop.
