Context
• Audiovisual metadata is essential• (incomplete) definitions :
– (AV) Annotation : any piece of data linked to an audiovisual fragment
– Augmented/annotated video : video augmented with annotation data
• What for?– Search / retrieval– Linking
– Navigation– Visualisation

Visualisation
• Variety of visualisation modalities• Two different goals:
– Find the most appropriate visualisation for the annotations for the current task
– Do not too tightly bind the annotations and their visualisations (prevents reusability)
► empower users with the ability to define their own visualisations

Hypervideo
• Term used by Ted Nelson (1960s)• A definition : interactive video-centric
hypermedia document built upon an audiovisual content augmented with data in a time synchronized way
• Two dimensions :– Hypermedia– Video-centered

• But : poor bet on visualisation emergence – did not meet appropriate users
– Need to provide bootstrap components/examples

– (AV) Annotation : any piece of data linked to an audiovisual fragment
– Augmented/annotated video : video augmented with annotation data
• What for?– Search / retrieval– Linking
– Navigation– Visualisation
- importance : evidence- ATM, metadata is mostly limited to ressource
metadata- Bridge the semantic gap- Search : first thing that comes to mind. Need to
cross the semantic gap though, it is the aim of many projects
- Linking : in the LinkedData perspective, AV cannot directly be linked. Need additional layers (annotations)
- Visualisation : seems obvious, but often overlooked: once you have found the video fragments that interest you, how do you visualise them appropriately ?

• Variety of visualisation modalities• Two different goals:
– Find the most appropriate visualisation for the annotations for the current task
– Do not too tightly bind the annotations and their visualisations (prevents reusability)
► empower users with the ability to define their own visualisations
- visualisation of augmented videos- «for the task carried out» : essential criterion- if we design annotation content with a specific
visualisation in mind, we can prevent the reuse of annotations through other means
- if we design visualisations too tighly linked with annotations, it prevents reusability -> lost time.
Until know, I have spoken about visualisation in general
Will introduce a concept that we think is appropriate

Hypervideo specificities
• Annotations mandatory to address/augment video content
• Variety of visualisation modalities• Space/time disorientation more pregnant• Cognitive load / time pressure• Rhetorical and aesthetic challenges
HV : restriction of generic hypermedia
Given the combination of video+annotations ->- variety : AV- or annotation-focused (subtitles vs
transcription) / temporal / non-temporal (static) / overview / detailed / synthesis...
- disorientation : common in hypermedia, but exacerbated
Before going into our proposal of a model for HV, I will give some information about where we come from.

CHM : Component-based Hypervideo Model
• Main goals :– Conceptual and implementable model– Explicit annotation decoupling– Expressivity / simplicity
- There are other hypermedia models that introduce time (AHM + NCM). Our approach is compatible with AHM (but with more focused)
HV is a restriction of hypermedia – profit from this constraint
