Hardman Supporting the generation of argument structure within video sequences ABSTRACT Browsing is a useful way of exploring annotated media repositories. Sets of links can be automatically created from the annotations associated with the media items in the repository. When there are also relationships among the annotations themselves, such as when the annotation terms are part of a thesaurus, these relations can also be used in the link generation process. Using structured annotations and a thesaurus for generating link sets has two advantages. The first is to evaluate the effectiveness of the terms in the thesaurus for classifying the media items in the repository. The second is to be able to control the links being generated by changing relationships within the thesaurus. The work is illustrated using video segments annotated with argument structures, but we show that the method used is independent of the media types and applicable to systems that use similar annotation structures and typed relations among them.

Automatic Generation of Matter-of-Opinion Video Documentaries

“…The elements of this form are points of view, positions and logos arguments 5 . Content in video is conveyed by the video track and in the audio track, which are processed by the visual and auditory perception channels, respectively.…”

“…The rationale behind this choice is that decomposing the process into two steps allows to better pinpoint how statements and terms in the thesauri contribute to the graph creation. This information can be used to improve the quality of the generated semantic graph ( [5]). We describe these two sub-processes in detail in the following two sections.…”

Blending coherence and control in the construction of interactive educational narratives from digital resources

“…Topia has been used to create interactive presentations containing the works of a particular artist or school and associated descriptive texts about the creator and the works. Bocconi, Nack, and Hardman (2005) organised video clips into argument structures, weaving comments from individuals into an apparent conversation or debate. The approach employs annotations of each video clip in terms of the assertions and lines of argument they contain.…”

Intentions based authoring process from audiovisual resources

“…The project Vox populi [Bocconi 2005] is mainly based on an argumentative modeling applied to a purely audio-visual corpus (a hundred interviews which capture the point of view of American citizens after the events of September 11, 2001). A user's query, by choosing a point of view, generates a semantic graph which is built dynamically starting from annotations of topic as well as of provided arguments.…”
