Information storage method and device

The invention discloses an information storage method and device. The method comprises the steps of performing named entity identification on an unstructured text to obtain a plurality of entity tags,storing the entity tags with association between every two entity tags in a triple form, and performing modeling representation on entities and/or relationships in an attribute graph in an ontology graph form to form an attribute graph ontology graph; according to the output type of each triad in the triad set and the attribute ontology graph, constructing a target rule for mapping the triads tothe attribute graph; and mapping the triples in the triple set into an attribute graph according to the target rule, storing the attribute graph into a topic graph, performing manual auditing on the topic graph, performing correction, and synchronously storing the topic graph into a knowledge base. By the adoption of the scheme, the incremental information is converted into the triad, then the triad is mapped into the attr
