The World Wide Web is transforming from strings to things
The authority data librarians curate are about things (people, places, …)

A discovery system revolving around authorities is one way of achieving this

Instead, they could give information on documents about things

A discovery system revolving around authorities is one way of achieving this
In the German speaking world, all authorities are collected in the GND
| 23 | Authority control and semantic interoperability | November 18, 20137
GND
PND SWD GKD EST
The GND uses an entity-based model
• Corporate Body
• Conference or Event
• Subject Heading
• Work
• Place or Geographic Name
• Family
• Person
| 23 | Authority control and semantic interoperability | November 18, 20138
The GND Ontology is a formalisation of that entity-based model in OWL

Libraries can leverage those structures to build entity-centric discovery
Topical search can revolve around subject headings
| 23 | Authority control and semantic interoperability | November 18, 201316
We can also explore networks of persons
| 23 | Authority control and semantic interoperability | November 18, 201317
Through vocabulary interlinking we can achieve (almost) true multilinguality
| 23 18
So is the use of semantic networks a cure-all for navigation in libraries?

We often focus too much on books and forget the authorities (people, places, …)

A discovery system revolving around authorities can add new perspectives

I see some far-reaching
opportunities!
