- Abstract
- Some database schema is very complex and it changes more frequently than the past. On the other hands, in such application database as scientific database and decision-support database, the importance of ad-hoc queries is expected to increase. Therefore the ability of a system to support ad-hoc queries without knowing the database schema information is needed, In this paper, we will describe a method to create candidate structured queries with concept hierarchy using user-input keywords. We will create structured queries in the following step; first, we extract the schema items related to keywords, and second, we compose possible paths between schema items, thus formulate candidate SQL queries.
