This article introduces the NRHM special issue on Interactive Digital Narrative (IDN) and Complexity. It first shortly describes the field of IDN and why developments with respect to content, content and interaction focus on complexity issues. It finishes with a short outline of the five papers that form the body of the special issue. [ABSTRACT FROM AUTHOR]

The article offers information on the development in the digital technology, focusing on interactive storytelling. It states that s everal modern movements can trace their roots back to this movement, such as the urban exploration movement, which explores the hidden city landscape through accessing underground tunnel systems and rooftops pathways.

This article considers the automated generation of humorous video sequences from arbitrary video material. We present a simplified model of the editing process. We then outline our approach to narrativity and visual humor, discuss the problems of context and shot order in video, and consider influences on the editing process. We describe the role of themes and semantic fields in the generation of content-oriented video scenes. We then present the architecture of AUTEUR, an experimental system that embodies mechanisms to interpret, manipulate, and generate video. An example of a humorous video sequence generated by AUTEUR is described. [ABSTRACT FROM AUTHOR]

While many multimedia systems allow the association of semantic annotations with media assets, there is no agreed-upon way of sharing these among systems. As an initial step within the multimedia community, we identify a small number of fundamental processes of media production, which we term canonical processes. We specify their inputs and outputs, but deliberately do not specify their inner workings, concentrating rather on the information flow between them. We thus identify a small set of building blocks that can be supported in semantically aware media production tools. The processes are identified in conjunction with a number of different research groups within the community who supply, in the companion papers, descriptions of existing systems and a mapping to them. We give a basic formalisation of the processes and discuss how this fits with other formalisation endeavours. We present a number of frequently asked questions during the development of the model and this special issue. [ABSTRACT FROM AUTHOR]
