Embodiment Construction
[0027] The present invention proposes a parallel graph summarization method based on attribute graph, such as figure 1 shown, including:
[0028] Step 1: Preprocess the obtained graph data, and process each node in the graph into a node structure with its own information and all direct neighbor information;
[0029] Step 2: Randomly select a direct neighbor node for the current node, and then select a node with the same attribute and maximum similarity as the current node among all direct neighbor nodes of the neighbor node as a candidate node to be merged with the current node;
[0030] Step 3: Determine whether the error introduced after the current node merges with the candidate node exceeds the error threshold. If it exceeds, return to step 2 to continue searching for other candidate nodes. If not, merge the two nodes;
[0031] Step 4: Perform two-node merging by updating all node information in the node structure, and repeat steps 3-4 until the number of remaining nodes ...
