Outline

• Why we need Semantics in CMS ?

• How can Semantic Web Technologies help ?

• How Redlink makes the integration much easier ?

!

• Excursus: What about Semantic Media Asset

Management Systems


"We are drowning in information and starved for knowledge." John Naisbitt

• Content is highly available through the Internet

• Information are distributed over people and systems

• Data is available in various media and technical formats

We need an efficient way for working with huge amounts of unstructured content


Content Management Systems

• CMS are a single point of entry, providing consistency and the

foundations for collaborative work with content

• CMS provide functionalities to handle large amounts of content:

• Creation of new content

• Editing of existing content

• Organisation and management of content

• Presentation of content

• Media-neutral data management (separation of layout and content)



State of Play in Content Management

• Current solutions provide efficient ways to manage

content

• Domain-specific requirements, like “multichannel content

distribution” are addressed

• Content can be managed and presented in multi-media

formats

… B U T …


Problems in current Content Management Systems

• Content is only “understandable” by users and not by machines

• Irrelevant search results

• Aggregation of relevant content needs to be done manually

!

• Inferring Knowledge from Content

• Dependencies, relations and inconsistencies among content items

need to be identified and defined manually

!

• Content is strongly connected to presentation

• works only inside a certain environment


The GOAL

DATA

INFORMATION

KNOWLEDGE

WISDOM

+ Context

+ Meaning

+ Insight

(Open) Linked Data

1. Use URIs as names for things

2. Use HTTP URIs so that people can look up those names.

3. When someone looks up a URI, provide useful information, using

the standards (RDF*, SPARQL)

4. Include links to other URIs. so that they can discover more things.


Semantic Lifting via Natural Language Processing


How should we handle this?


The Redlink Platform



• Read-Write Linked Data

• Triple store with transactions, versioning and reasoning

• SPARQL and LDPath query languages

• Transparent Linked Data Caching

The Open Platform for Linked Data

http://marmotta.apache.org/

http://marmotta.apache.org/


• Semantic Enhancement process chaining

• Several Natural Language processing facilities

• Multi-language support

• Classification and Sentiment Analysis

http://stanbol.apache.org

The Toolbox for Semantic Lifting

http://stanbol.apache.org


• Based on Apache Lucene

• Many language specific processing procedures

• Highly scalable (Solr cloud) and ultra fast

• Highly configurable

The highgly scalable Search Server

Media Asset Management Bridging the Semantic Gap


Semantic Media Asset Management Systems

• Multimedia Content is enormously growing within the last

decade (Web 2.0)

• Multimedia Content must be prepared for automatic processing

• for multimedia retrieval

• for reuse across platforms, contexts, locations, languages

• Multimedia Content Management Systems heavily rely on high

quality metadata (meaning is hidden Semantic Gap)


Semantic Web Technologies can bridge the gap


Where we use Semantics

• Controlled Vocabularies

• Domain specific Thesauri using standard representations

• Reuse of external data

• Create Knowledge by linking

• (Semi-) Automatic Metadata enrichment and classification

• Semantic Search (Facetting, Synonymes, Multilingual)


What do we need to bring Media Objects in the Web of Data


Media Fragments

„ … a media-format independent, standard means of addressing

media fragments on the Web using Uniform Resource Identifiers. “ [W3C Recommendation: Media Fragments URI 1.0 (basic)]

Media Resource Description

provide a core set of descriptive properties.“ [W3C Recommendation: Ontology for Media Resources 1.0]

Hello, my name is Tom!

Last summer I was in Paris in France for vacation. It was really amazing. I love Paris!


RDFize Tom's statement

Tom likes Paris, France. -‐> Tom likes Paris. -‐> ( Tom, likes, Paris ) -‐> Paris is a part of France. -‐> ( Paris, partOf, France )


RDFize Tom's statement

Tom likes Paris, France. -‐> Tom likes Paris. -‐> ( Tom, likes, Paris ) -‐> Paris is a part of France. -‐> ( Paris, partOf, France )
