The cosmic large-scale structure from galaxy redshift surveys provides a powerful probe of the properties of dark energy and the time dependence of any cosmological model in a manner that is highly complementary to measurements of the cosmic microwave background, supernovae, and weak lensing. The scope of galaxy redshift surveys has dramatically increased in the last decades. We are developing the methodologies which aim to extract the cosmological information with the most robust way in terms of taking care of the priors, observational and theoretical systematics. These considerations would become more important with the increasing observed volume of galaxy surveys. We have applied our methodologies on the latest SDSS-III/BOSS galaxy sample. In addition, we extend our methodologies by considering the impact of varying neutrino masses. In the end of this talk, I would like to mention the works we have done regarding extracting cosmological information from void clustering.
