1- What is the current research on SA? Is it used? Why it did not have the some success of others techniques?
2- What are the advantages of using SA over SVD (Scalar Vector Decomposition)?
3- At the methodological level how is it possible to evaluate the performance of a IR system over another, given the fact that some of the parameters used for these measures are human based (i.e., defining what is relevant in a given collection returned by a query)?
Please feel free to chime in!
