Latest Patents

The provided information lists 1 patent for Yi Zhan: “Structured Query Statement Similarity Detection Method and Apparatus, and Device.” The invention describes acquiring two structured query statements and constructing an abstract syntax tree for each. It then traverses nodes in the first tree, matches them with nodes at the same level in the second tree, and uses the matching results and corresponding weights to determine statement similarity. The method gives particular consideration to the root node and its child nodes, reflecting their relevance to the query results.
