How to handel this?
Unified platform, Drupal7, 2012

News, current affairs, sports, entertainment, lifestyle, recipes, health, science, debate – all in one hierarchically flat platform.
MUST ALSO BE UNIFORM AS DATA!

Referer trafic

- Machine readability- Semantic metadata - Linked data- Open data- SEO
The content must be able to live independently from the platform!
![Page 9: Svenska Yle metadata and data first](https://reader037.vdocuments.mx/reader037/viewer/2022103117/55b6c26bbb61eb12388b45d9/html5/thumbnails/9.jpg)
Content – i.e. articles – rule!
60% of the trafic starts from an article, 29% from the main page. 11% covers everything else!

Metadata is the key
• Content, platform and distribution are exploding in diversity.
• We need to be able to serve the web with our content as data.
• Semantically rich ontologies with public URI’s• We use Finto (Finnish ontology and thesauri service) and
Freebase >> Wikidata ca. Aug. 2015• Linked data
• Map relation’s between content to link them together • Data graph
• This graph gives structure, recommendations, search engine optimization, new knowledge, global intercompability
= Data first

The components• Finnish ontology and thesauri library
(FINTO) www.finto.fi • Frebase www.freebase.com • Drupal module for annotation:
https://www.drupal.org/project/yild
• + journalists do the base annotation• complemented with automatic annotation
• New module can utilize wikipedia, geonames > almost all open metadata repositories: YILD – Yle Integrator for Linked Data https://www.drupal.org/project/yild

Yle-API• On top of our metadata sits an
Yle API-layer (API = application programming interface)
• Meta-API ties together all Yle-metadata to a graph
• API-calls in JSON(-LD)• Compatible with Schema.org, EBUCore och Dublin

The opening of Yle-APIWe have taken the first steps to start opening up our API’s by publishing the Programmes API.
When the Articles- and meta-API’s are opened 3rd party developers can build own versions of most of our services

Annotation – journalists vs. algorithms
Journalists:
+ abstraction+ logic
- inconsistancy in both quality and quantity- poor attention to detail
Algortihms:
+ attention to detail+ consistancy
- lack of human logic- lack of languag knowledge - idioms- great sense of detail

• Based on semantic tags• Easy to add more
attributes like metrics• Can be improved by
algorithms, like cos-similarity
• Must be careful to not make too exact recommendations > boring
• Serendipitet, show the audience what they didn’t know they wanted to know

How?It’s really quite simple Below note to developer who built it.
![Page 25: Svenska Yle metadata and data first](https://reader037.vdocuments.mx/reader037/viewer/2022103117/55b6c26bbb61eb12388b45d9/html5/thumbnails/25.jpg)

ExampleThe same content after 3 months. The graph lives!

Hur?Still demands quite complicted api-calls must optimize
