Introduction

• MediaMixer promotes the use of semantic technologies for media mixing

• Apply them in real use cases and demos– Fragmenting media assets– Annotating them using semantic descriptions– Exposing descriptions for fragment level

search– Representing, integrating and reasoning about

rights information

08.04.2023 Slide 4 of 26

Use Case

• User Generated Content

08.04.2023 Slide 5 of 26

Use Case

• UGC from reused media

“Gangnam Style”, plus +33,000 videos using it, more than $870,000 ad revenue - New York Times, Dec 7th 2012

Use Case - Disputes

• What if more than one ownership claim?

• If disputed, no one can monetize

08.04.2023 Slide 9 of 26

Use Case - Claim?

• Are we sure we can claim?• Do we own that particular copy?• In that territory?• Also in relation with streaming and

YouTube?• Does the artist like being on

YouTube?• …

08.04.2023 Slide 10 of 26

Use Case - Claim?

Thousands of pieces of registered content…Thousands of videos on YouTube…

• Decision Support System (DSS)– You can claim on content-id X– You can’t really claim on content-id Y– Trade X for Y with C (who owns Y and

wrongly claims X)

08.04.2023 Slide 11 of 26

Use Case - Claim?

• Rights DSS requirements:– Fine grained– Scalable (largely automatized)– Takes into account:

• Contracts“…all rights on the live version but studio version just in the US.”

• Policies“…artist does not want his music together with violent images”.

• Rights Expression LanguagesDDEX metadata: <UseType>OnDemandStream</UseType>

<TerritoryCode>Worldwide</TerritoryCode>

• Goal: transform whole videos to sets of meaningful, indexable and re-usable video fragments

Baseball, Throwing, Sports, Plant, Running, …

Annotation

08.04.2023 Slide 14 of 26

Linked Data

• Globally unambiguous identifiers for any concept needed– Ideally more information

about the concept itself is available via the identifier

– Use of Web URIs → Linked Data concept space

– Would allow for inference of concept type and relationship to other concepts

Copyright ReasonerReasoning Explained

• Vocabularies and ontologies provide the building blocks:– Classes– Properties– Instances– Restrictions– …

Copyright Ontology Schema.org

Media Ontology

08.04.2023 Slide 29 of 26


• These blocks can be combined to model facts like:– A person is the creator of an asset– An asset is part of a compilation– …or an employee wants to reuse a

piece of content.

• Blocks can also model patterns to be matched by facts:– For instance a rights expression

authorising to reuse a mediafragment…

• All these models are then placed into a reasoner– A tool based on semantic technologies capable of mixing

them taking into account ontologies (constraints, functions, rules,…)

08.04.2023 Slide 33 of 26


• Ontologies teach the reasoner how to: – Detect when some facts match a pattern

08.04.2023 Slide 34 of 26


• Ontologies teach the reasoner how to: – Give precedence to patterns so others cannot

match

08.04.2023 Slide 35 of 26


• Ontologies teach the reasoner how to: – …and interpret some patterns as allowed and

others as prohibited

• So they can respond to queries based on all this:No, because it is matched

to pattern

which prohibits it.
