Revisiting Character-Based Affective Storytelling under a Narrative BDI Framework

Abstract. This paper presents an ontological approach to the domain of drama. After a description of the drama domain in a cross-cultural and media setting, we introduce the ontology Drammar. Drammar consists of two components, encoding respectively the conceptual model and the SWRL rules. The conceptual model, mainly grounding in AI theories, represents the major concepts of drama, such as agents, actions, plans, units, emotions and values. Then, the paper focuses on the rule component that augments the representation by mapping the intentions of the characters onto the actions actually performed and by appraising the emotion felt by the characters in the drama. To illustrate the functioning of the ontology we introduce a running example from an excerpt of the drama Hamlet. Finally, we carry out an evaluation of the approach on an annotation task that is relevant for drama studies research and teaching. In particular, the emotion appraisal is tested on the main characters of four dramas of di↵erent nature, by computing precision and recall results with respect to a human annotator.

Coupling conceptual modeling and rules for the annotation of dramatic media

“…Goals originate from the values of the agents, i.e., put at stake or balanced through the plan actions. The representation of dramatic characters is formalized through the rational agent paradigm, or Belief Desire Intention (BDI) paradigm [4] (which has already seen some applications in the computational storytelling community [18] [20]). The dramatic scenes of the story are the places for the interplay of the actions that are carried out by the agents to achieve their goals.…”

Automatic Annotation of Characters’ Emotions in Stories

Interactive Storytelling

Abstract. The emotional states of the characters allow the audience to understand their motivations and feel empathy for their reactions to the story incidents. Consequently, the annotation of characters' emotions in narratives is highly relevant for story indexing and retrieval but also editing and analysis. In this paper, we address the construction of tools for the annotation of characters' emotions in stories, opening the way to the construction of a corpus of narratives annotated with emotions.

“…Agents, in fact, are the most complex entities (such a complexity is revealed by the number of properties having agents as domain). Agent representation in Drammar descends from the BDI theory [9], which has already seen some applications in the computational storytelling community [44] [47]. According to BDI, an agent is a tripartite function of Beliefs, Desires (or Goals), and Intentions (or Plans of actions), where beliefs are the knowledge of the agent (what it knows or believes to be true), goals are the objectives to be achieved through the plans of actions.…”

Multimedia tool suite for the visualization of drama heritage metadata

Multimed Tools Appl

This paper presents a multimedia tool suite for, on the one hand, the annotation of metadata that encode the dramatic qualities of cultural heritage items, and, on the other, the visualization of such metadata for drama analysis and didactics. The tool suite relies upon an ontology of drama to devise an annotation schema for the metadata concerning the dramatic qualities. The two major modules of the tool suite are a web-based platform, that allows for the insertion of the annotation metadata, and a visualization program for the interactive exploration of such metadata, respectively. The tool suite was tested on the cross-media studies of drama analysis and teaching of drama structure through the application to classical examples.
