Table 1 Previous user interest modeling research has established the significance of mapping user actions to video semantics, but there are drawbacks in all approaches
User interest modeling | Advantages | Disadvantages |
|---|---|---|
Ma et al. [5] | Assumes that viewers are interested in particular well defined and easy to retrieve content features (e.g., faces) | Content-based and thus static vocabulary of what is interesting |
Shaw and Davis [17] | User comments and tags | Do not have time information |
Shaw and Davis [17] | Remix of popular video segments | Only a portion of users perform re-mixes of video |
Shamma et al. [19] | Micro-blogs are associated to TV broadcast | The timing information might not correspond to video cue time |
Carlier et al. [25] | Zoom denotes areas of interest within a video frame | Zoom is not a common feature |
Olsen and Moon [23] | Interest function | Explicit ratings |
Peng et al. [24] | Eye tracking and face recognition | Web camera |
