Term associations in query expansion
Michael Edward Symonds, Guido Zuccon, Bevan Koopman, Peter Bruza, Laurianne Sitbon · 2013
Many successful query expansion techniques ignore information about the term dependencies that exist within natural language. However, researchers have recently demonstrated that consistent and significant improvements in retrieval effectiveness can be achieved by explicitly modelling term dependencies within the query expansion process. This has created an increased interest in dependency-based models.
