Iterative Query Reformulation Model with Multiple Information Sources.

[felipemoraes]

In this model for Dynamic Search, I will estimate the parameters with CA algorithm.
At each iteration we reformulate the original query and add more terms that appear on the feedback passages for that query.
As Query Reformulation from Multiple Resources Model, I will test the one proposed in the following papers:

• Effective query formulation with multiple information sources. Michael Bendersky, Donald Metzler, and W. Bruce Croft. In Proc. of WSDM 2012.
• Parameterized concept weighting in verbose queries. Michael Bendersky, Donald Metzler, and W. Bruce Croft. In Proc. of SIGIR 2011.
