The present invention discloses a deep webpage data source classifying management method based on a query interface connecting picture. The method includes the following procedures: (1) acquiring the form assembly of a deep webpage query interface; (2) automatically extracting the characteristic values of the query interface form acquired in procedure (1) which comprises a form label name and attribute values; (3) constructing characteristic vectors of the form; (4) acquiring an associated adjacent matrix related with label, attribute value and the combination of label and attribute value, through the similarity comparison among vectors; (5) constructing a connecting picture of the query interface form assembly which can be expressed by the associated adjacent matrix; (6) utilizing a clustering method to cluster weighted undirected graphs; (7) acquiring the clustering result of the deep webpage data source. The present invention increases the automatic classifying management performance of the large-scale deep webpage data source through effectively constructing the query interface connecting picture of the deep webpage data source and combining with the graph mining.
