The invention discloses a
data classification method and device based on
machine learning, equipment and a storage medium, and relates to the field of
machine learning. Constructing and training a classification model by taking the extracted bag-of-words vector as model input and the classification identifier as target output, and constructing a structured
knowledge graph by taking the keywords extracted from the model, the classification and the
weight coefficient as knowledge entries; to-be-classified field information is obtained, keyword matching is carried out based on the
knowledge graph, graph keywords contained in the to-be-classified field information are extracted, and a graph keyword set is constructed; and extracting graph keywords, matching candidate classifications by matching knowledge entries, and screening target classifications based on
weight coefficient scores. According to the scheme, explicit expression and dynamic fusion of
machine learning are achieved by constructing the
knowledge graph, the contradiction that classification decision cannot be explained and knowledge is difficult to update is effectively solved, the defects that a rule method is rigid and a
machine learning method is black in a traditional technology are overcome, and the adaptability and reliability of a
system in a dynamic service environment are improved.
