Constructing presentations as stories is about presenting events that receive their relevance and meaning within the context of the presentation, and about means to define a well-structured relationship between events and the whole presentation scheme. Information in the form of annotated web content has become the most preferred source to create functional and interesting presentations because of its flexibility and availability. Nevertheless, due to the large and diverse amount of information contained in the web, the automatic construction of presentations becomes increasingly difficult in terms of the content annotation and selection in order to define events and the arrangement of such events in a coherent and story-like manner. In this paper, we present a novel method for the construction of web presentations by implementing a simple event annotation scheme based on Rhetorical Structure Theory and an ontology-based reasoning engine that handles event sequencing to produce presentations in the form of dialogs between character agents.
