Abstract
Research in relational keyword search has been focused on
the efficient computation of results from multiple tuples as well as strategies
to rank and output the most relevant ones. However, the challenge
to retrieve the intended meaningful results remains. Existing relational
keyword search techniques suffer from the problem of returning many
incomplete results. In this work, we adopt a semantic approach to relational
keyword search via an Object-Relationship-Mixed graph (ORMgraph).
This graph is constructed based on database schema constraints
to capture the semantics of objects and relationships in the data. Each
node in the ORM-graph represents either an object, or a relationship, or
both. We design an algorithm that utilizes the ORM-graph to process
keyword queries. Experiment results show our approach returns more
complete and meaningful results compared to existing methods, and is
efficient.
