In this paper, a result presentation method of keyword search over databases named S-CBR (schema-based classification, browsing and retrieving) which includes three phases of result classification, user browsing, and retrieving is proposed. Firstly, S-CBR uses database schema and query keywords to produce the first-level classes automatically and classify results into them. For large classes, it further partitions them based on the content of keyword nodes. Furthermore, S-CBR gives each class a readable description, and presents the description and each result graphically to help users understand the results easily. Users also can retrieve the class which they are interested in based on the information of the first-level classes to find the results they need or acquire more relevant results. Experimental results verify the method's effectiveness and efficiency.
