MediaMap Core : an ontology for audiovisual production

431 vues

Publié le

The MediaMap Core is an ontology for audiovisual production aimed to foster amateur/professionnal production, asset management, indexing and repurposing.
Our asset modeling focus on audiovisual fragment rather than whole program to facilitate commissionning, search and repurposing on a finer granularity.
We also propose a new way to describe these fragment during their production through a shooting script-based indexing. It relies on framing (camera parameters, effects, etc.) and composition information (element posture, movement, shot values, etc.).

MediaMap Core : an ontology for audiovisual production

  2. 2. EMWRT 816, May 2013 – Compiègne, FranceGoals and ApproachContributive production and fragment-based repurposingAcquisition : commission and searchDelivery : indexing and repurposingSemantic is the way to goSemantic modeling : what kind of ontology are we building ?Semantic Asset Management : manage each component of an assetSemantic description : professionnal and production-centered indexingSemantic process : knowledge gathering throughout the chain
  3. 3. EMWRT 816, May 2013 – Compiègne, FranceContributive production processMutli-source fragment acquisition+ Scripting : prescription of fragments needed in post-production+ Commissionning : content is shot externally and indexed before delivery+ Search : content and description are transformed in the desired format+ Acquisition : fragment semantic indexing + production knowledge update +shooting script update
  4. 4. EMWRT 816, May 2013 – Compiègne, FranceAmateur/professionnal productionHow to leverage amateur production quality ?+ Scripting (Script)framing and composition shot by shot+ Shooting (Script + Camera + Software)shooting process guidancedetailed instructions and illustrations for amateurlive feedbacks during shootingshot annnotation (people, location, etc.)+ Acquisition (Script + Shot + Annotation)preindexing of each shot + annotation
  5. 5. EMWRT 816, May 2013 – Compiègne, FranceSemantic modelingAsset = fragment + indexingContent = structured set of assets+ What kind of content and indexing do you need ?+ Models focused on media file and distribution dont represent intermediaryfragments or production knowledge+ Only a production model can cope with the challenge of contributiveproduction and fragment repurposingAsset description is only a mean to an end+ There are as many ways to describe an asset as there are users and goals+ Shooting script description is a good way to commission or search forfragments
  6. 6. EMWRT 816, May 2013 – Compiègne, FranceExogenous/Endogenous approachesFile/Asset management+ Exogenous models represent only the final resultof the production (media file)+ Abstraction levels are used to manage all the fileshaving technical similarities or for informationfactoring but disregards editorial aspects orconsequences+ Endogenous models follow the dynamic of the production process to representthe fragment to-be-produced and its (multiple) manifestation(s)+ An Asset is the combination of multiple components (editorial, sequence, file),each of which is representing an intermediary result of the production, makingit possible to manage each component independentlyMPEG-7 Content Management
  7. 7. EMWRT 816, May 2013 – Compiègne, FranceKnowledge and Assets inthe production process+ Planning : commission order, etc.+ Shooting Script : editorial structure (shot, scene, etc.), framing, composition+ Fabrication : multiple takes for one shot+ Derushing : production report, takes selection/segmentation, etc.+ Editing : take re-segmentation, editorial restructuration, multiple edits+ Distribution : multiple releases (web, broadcast, etc.)+ Archive : high-quality release + indexing
  8. 8. EMWRT 816, May 2013 – Compiègne, FranceExogenous/Endogenous approachesFile/Asset description+ Exogenous models use signal processing to build up information afterproduction- mostly technical and morphological- also descriptive but with the semantic gap as a serious obstacle+ Other models are used to associate administrative (production related) ordomain/task-specific information to the file+ Endogenous models collect knowledge as it is expressed/updated bycontributors during production, thus facilitating- exchange information between contributors- custom-tailored knowledge selection and presentation- asset archiving and repurposing
  9. 9. EMWRT 816, May 2013 – Compiègne, FranceMediãMāp approachendogenous during productionexogenous for exploitationAssociate any kind of knowledge to an assetWhenever needed in the processWhatever the methods used to create/collect it
  10. 10. EMWRT 816, May 2013 – Compiègne, FranceSemantic Asset ManagementarchitectureAsset and knowledge gathering throughout the chain+ Capture the domain knowledge contained in the production documents to build adescriptive Knowledge Base (KB) associated to AV fragments(commission order, shooting script, production report, etc.)+ Model the production process in a KB to provide a custom-tailored view oncommission order to each contributor depending on its role, skill, mission+ Search and reuse intermediary fragments of the chain from a repository(shot, scene, take, edit, broadcast release, web release, archive, etc.)Semantic DB project (contributor, process, commission, deliverable, etc.)Semantic DB fragment (components, struture, description, etc.)Asset repository (media file, edit file, etc.)
  11. 11. EMWRT 816, May 2013 – Compiègne, FranceSemantic modelingWhat kind of ontology are we building ?+ Multimedia ontology are heterogeneous and mostly exogenous(MPEG-7 based, EBU-core, W3C Media annotation, etc.)+ Heavyweight upper ontology are quite difficult to use for professionnal users(Dolce, ABC, SmartSUMO, etc.)+ Lightweight ontologies are not built using ontological methodology(XML transformation, UML modelling)or lacks important formal features(disjointness, inverse relations, distinctive traits between sibling, etc.)There is a need for a middle way : a core ontology- easy to understand because focused on one domain- formally built to maximize inference and alignment
