In this paper we describe a method to obtain summaries focussed on chosen characters of a free text. Summaries are extracted from discourse structures, which resemble rhetorical trees. They are obtained by exploiting cohesion and coherence properties of the text. Evaluation intends to evidence the contribution of each module in the final result.

We present a discourse parsing architecture based on an incremental approach and aimed at building a rhetorical structure of a free text.

The present paper extends that translation to s...
