Keyword Search over Relational Databases: A Metadata Approach

Summary: Metadata-based framework for keyword search in relational DBs without precomputed indices or full content access. The method casts keyword-to-SQL translation as a joint assignment problem solved by the Hungarian algorithm, capturing inter-dependencies among keyword mappings and yielding semantically faithful SQL queries, with thorough experiments.
