Nested Event Model for Multimedia Narratives

The proliferation of multimedia narratives has contributed to what is known as the "crisis of choice", which demands a much more active participation on the part of the user to consume multimedia content. To address this issue, a strategy is to offer users efficient search mechanisms, sometimes based on ontologies. However, one may argue that such mechanisms are often based on abstractions that do not adequately capture the essential aspects of multimedia narratives. This paper proposes a conceptual model to specify multimedia narratives that overcomes this limitation. The model is based on the notion of event and is therefore called Nested Event Model (NEMo). The paper also includes a complete example to illustrate the use of the model.
