A second difference is that whereas, in our approach, syntax and aggregation choices are guided by a hypertagger trained to predict the best sequence of syntactic constructs for a given input, in Lampouras and Androutsopoulos the aim is to systematically minimize the length of the output, that is, to maximize aggregation.
we allow for various ways of aggregating a given content into different sentences and select one based on linguistic and semantic criteria, whereas Lampouras and Androutsopoulos (2013) select the aggregated sentences based solely on sentence length.
