Web database schema identification through a simple query interface
Lizhu Zhou · Journal of Tsinghua University(Science and Technology) · 2010
Web databases (WDB) provide different types of query interfaces to access data. While the simple query interface (SQI) is one of the most popular interfaces,most existing works use a complex query interface to perform schema recognition of the backend databases. This paper presents a method for instance based query probing and schema identification through SQI. A query probing strategy was developed to generate the full-conditioned query. An extended identification method for the non-query attributes for result schema was developed to effectively improve the attribute recall rate. Tests on website of online book,movie and mobile phone shopping sites show that this method achieves accurate recall of schema identification.
