The invention discloses a
deep learning-based question and answer
knowledge graph construction method and
system, and the method comprises the steps: collecting multi-dimensional question and answer data of a target domain from a plurality of data sources, carrying out the cleaning and
standardization processing of the question and answer data, so as to eliminate
noise information, and generating a preliminary
data set; performing semantic analysis on the question and answer data by using a
deep learning model, and generating a context embedding representation of each question and answer text in the question and answer data; knowledge entities and relationships among the entities are identified from the context embedding representation, and a preliminary knowledge triple is constructed; and based on the knowledge triad, constructing a preliminary question and answer
knowledge graph for the identified entities and relationships, and allocating a
unique identifier to each node in the preliminary question and answer
knowledge graph to generate a structured question and answer knowledge graph. By utilizing the embodiment of the invention, the question and answer knowledge graph construction efficiency and the semantic understanding capability can be remarkably improved, and the application of an intelligent question and answer
system in a complex scene is promoted.
