Abstract
The present disclosure provides an information extraction method. The method includes obtaining an unstructured text data; parsing the unstructured text data based on a node format; and generating a first node set that comprises nodes describing the unstructured text data. The method further includes obtaining a rule database, the rule database comprising a plurality of rules used for generating a node, each rule designating a role of a node generated by using the rule, and the role of the node being a root node or a non-root node; synthesizing the nodes in the first node set based on the rule database to generate a root node; and generating structured data based on the root node.
