This paper presents a Deep Web data sources discovery method based on ontology.It uses webpage classification,form structure classification and form content classification to find Deep Web querying interface in some fields.It proposes that semi-automatic construction and automatic extension of ontology are added to the webpage and form content classification,and heuristic rules are enriched in the form structure classification.Experimental results show that this method can improve the precision and recall of Deep Web database discovery effectively.
