Meaningful keyword search in relational databases with large and complex schema
2015
2015 IEEE 31st International Conference on Data Engineering
Preserved Fulltext
An answer is a join tree of tuples that contains the query keywords. We present a new framework for finding meaningful answers to the keyword search problem over databases with complex schema. ...
Keyword search in databases helps users who are not familiar with the database schema or a query language to explore the database efficiently. ...
In this paper, we use schema-based ranking to solve the problem of keyword search over relational databases. ...

XML keyword search has attracted a lot of interests with typical search based on lowest common ancestor (LCA). ...
However, in this paper, we show that meaningful answers can be found beyond LCA and should be independent from schema designs of the same data content. ...
Keyword search is a user-friendly way so that users can issue keyword queries without or with little knowledge about the schema of the underlying data. ...

Keyword Search over Relational Databases: Keyword search on relational databases [1, 3, 18, 16, 26] has attracted much interest. ...
In this survey, we discuss methods of keyword search on schema graphs, which are abstract representation for XML data and relational data, and methods of keyword search on schema-free graphs. ...
Because of the underlying graph structure, keyword search over graph data is much more complex than keyword search over documents. ...
