Web search engines and specialized online verticals are increasingly incorporating results from structured data sources to answer semantically rich user queries.  ...  For example, the query Samsung 50 inch led tv can be answered using information from a table of television data.  ...  In this paper, we formulate the above problem as timebound query rewriting for structured web queries.  ...

We demonstrate the feasibility of this approach by providing a query interface for integrating hundreds of (real) structured Web information sources.  ...  These queries are rewritten using a best-effort approach: the rewriting component compares a user query against the source schemas and produces a set of rewritings based on the matches found.  ...  The Crawler is responsible for finding relevant structured Web sources. Because structured information is sparsely distributed on the Web, we use a focused crawler for this task [2, 3] .  ...

To enhance the evaluation flexibility of twig queries, we come up with further rewrite rules to prepare query graphs-even before query transformation-for making the most of existing joins and indexes.  ...  For twig queries, we define a set of rewrite rules which initiate query graph transformations towards improved processability, e. g., to fuse adjacent binary join operators to a complex join operator.  ...  Acknowledgments We thank Sebastian Bächle and the anonymous reviewers for their valuable comments on this paper.  ...

Viewing a world of annotations through AnnoVIP

<span title="">2010</span> <i title="IEEE"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/vuw5ktdyknehrehttg5qm4rfqm" style="color: black;">2010 IEEE 26th International Conference on Data Engineering (ICDE 2010)</a> </i> &nbsp;
ACKNOWLEDGMENT We are grateful to Ioana Manolescu for her substantial guidance and support in this work. We are also thankful to Alin Tilea for his contribution in developing the system.  ...  The extension we brought concerns the support for annotations, value joins in the query language, and specific techniques for materializing join views and rewriting queries including value joins.  ...  However, this still did not provide sufficient leeway to establish efficient data access support structures.  ...

We demonstrate the feasibility of this approach by providing a query interface for integrating hundreds of (real) structured Web information sources.  ...  We also discuss experimental results which indicate that our query rewriting algorithm is both effective and scalable.  ...  The Crawler is responsible for finding relevant structured Web sources.  ...

Efficiently querying RDF [1] data is being an important factor in applying Semantic Web technologies to real-world applications.  ...  For some extreme cases, they can promote 3 to 4 orders of magnitude.  ...  ., subject-subject and subject-object) are common methods for improving RDF query performance on the vertical database structure.  ...
