Web database schema identification through simple query interface

摘要: Web databases provide different types of query interfaces to access the data records stored in backend databases. While most existing works exploit a complex interface with multiple input fields perform schema identification databases, little attention has been paid on how identify web by simple (SQI), which only one single text field. This paper proposes new method instance-based probing WDBs' and result for SQI. The problem is defined as generating full-condition SQI novel strategy proposed. also identified based webpages SQI's query, an extended non-query attributes proposed improve attribute recall rate. Experimental results online shopping book, movie mobile phone show that our effective efficient.
