Mehdi Kargar, Aijun An, Nick Cercone, Parke Godfrey, Jaroslaw Szlichta, Xiaohui Yu
2015 2015 IEEE 31st International Conference on Data Engineering  
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.  ...

In this information searching is done with the help of keyword which is known as query keyword and searching is called as keyword searching.  ...  A huge amount of research work focusing on the keyword searching, retrieval and query processing has been done in the relational database.  ...  Schema-based approaches support keyword search over relational databases by direct execution of SQL commands.  ...

However, this is not sufficient when searching a complex schema. We demonstrate MeanKS, a new system for meaningful keyword search over relational databases.  ...  An answer is a join tree of tuples that contains the query keywords. When searching a database with a complex schema, there are potentially many answers to the query.  ...  Keyword search over databases can bridge this gap.  ...

Schema-Independence in XML Keyword Search [chapter]

Thuy Ngoc Le, Zhifeng Bao, Tok Wang Ling
2014 Lecture Notes in Computer Science  
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.  ...

A Survey of Algorithms for Keyword Search on Graph Data [chapter]

Haixun Wang, Charu C. Aggarwal
2010 Managing and Mining Graph 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.  ...

XIOTR :A Terse Ranking of XIO for XML Keyword Search

Xia Li, Zhanhuai Li, Qun Chen, Ning Li
2011 Journal of Software  
We design an XML keyword search approach, that can derive the keyword query and generate a set of effective structured queries by analyzing the given keyword query and the schemas of XML data sources.  ...  But Keyword search is hard to directly improve search quality because lots of keyword-matched nodes may not contribute to the results.  ...  Keyword search over databases allows users to find pieces of information without having to write complicated structure queries.  ...

But if the relationship among the objects is more complex, using databases for storing ontologies is an approach to be better.  ...  However, using relational databases do not sufficiently support the semantic orientated search by Structured Query Language (SQL) and the searching speed is slow.  ...  Their system extends the existing schema-free Keyword Search over relational database systems with semantic match features.  ...

Secondly, these query languages require the queries to be posed against the underlying, sometimes complex, database schemas.  ...  In this paper, we study the problem of effective keyword search over XML documents.  ...  However, existing proposals on keyword search over XML databases suffer from two problems: meaningfulness and completeness of answers, and the scope of the search.  ...
