Structural Query Expansion via motifs from Wikipedia

Joan Guisado-Gámez, Arnau Prat-Pérez, Josep Lluís Larriba-Pey
2017 Proceedings of the ExploreDB'17 on - ExploreDB'17  
We propose Structural Query Expansion (SQE), a method that relies on relevant structures found in knowledge bases (KBs) to extract the expansion features as opposed to the use of semantics.  ...  SQE is capable of achieving more than 150% improvement over non-expanded queries and is able to identify the expansion features in less than 0.2 seconds in the worst-case scenario.  ...  We propose Structural Query Expansion (SQE), a new query expansion strategy that exploits KBs relying exclusively on the structural relationships of its entries.  ...

Translation techniques in cross-language information retrieval

Dong Zhou, Mark Truran, Tim Brailsford, Vincent Wade, Helen Ashman
2012 ACM Computing Surveys  
Unlike IR, CLIR must reconcile queries and documents which are written in different languages.  ...  The usual solution to this mismatch involves translating the query and/or the documents before performing the search. Translation is therefore a pivotal activity for CLIR engines.  ...  ACKNOWLEDGMENTS This research was partially supported by a PHD scholarship from the University of Nottingham and funding from the Science Foundation Ireland (Grant 07/CE/I1142) as part of the Centre for  ...
