Kind Code:
A1
Abstract:
A knowledge graph-based text comparison method, relating to the big data technology. Said method comprises: acquiring training text, recognizing target entities and target relationships in the training text, then generating a graph by taking the target entities as nodes and the target relationships as edges, and taking the graph as an initial graph; marking the target entities and the target relationships of the initial graph, and clustering the nodes of the initial graph according to the marked target entities and target relationships, so as to obtain a target graph; acquiring text to be compared, and inputting said text into the target graph, and calculating a coverage rate, on core information in the target graph, of entities and relationships extracted from each piece of said text; and if the coverage rate exceeds a preset threshold, determining that said text is text of the same category. The present invention further relates to blockchain technology, and said text is stored in a blockchain. The method increases the text comparison accuracy and efficiency by means of graph comparison.
