... in the introduction and in section 2, since CRFs and models for parsing constitute the main issue in our work, we discuss some important models here. Beyond the models for parsing discussed in section ... Fillers of named entities should be, in principle, distin- guished from any other filler, since they may be informative to discriminate entities. Following this intu...
