Towards a conceptual model for cognitive-intensive practices

Different conceptual data models in the literature are either geared towards the description of low-level features of media content or to more abstract and complex conceptual representations. A lesser number attempt to cover both purposes, i.e. to support both low-level aspects and high-level concepts in a single reasoning process. However, these models lack the needed expressiveness to represent cognitive-intensive activities, which are tightly based on production and consumption of knowledge present in multimedia content and commonly relate concepts at arbitrary abstraction levels. This work aims to contribute to a better understanding of how it could be possible to model the knowledge "flow" in such activities, which may include the collaboration of different cognitive systems (human and software) and interaction with devices, software interfaces, and real objects.
