This class is used for our implementation of: "Searching Patterns for Relation Extraction over the Web: Rediscovering the Pattern-Relation Duality" . Y. Fang and K. C.-C. Chang. In WSDM, pages 825-834, 2011. For further information, WSDM 2011 Conference Website .

Description

Generation of queries for specific search Engines. The implementation of the Search Engines and Query Generator used must correspond in their implementation to obtain the expected results. To understand how the queries are generated please refer to Algorithm PatternSearch(To,S,E) in Figure 9 on Section 5 of the paper mentioned here.
