authority control and semantic interoperability
DESCRIPTION
When the web moves from strings to things libraries can leverage on their authority data to improve the navigation in their catalogues and thus to help improve the user experience. In this presentation held at a workshop organised by the URBS library community in Rome on November 18, 2013, I try to give theoretical and practical examples of how this can be implemented.TRANSCRIPT

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, …)
| 23 | Authority control and semantic interoperability | November 18, 201320
A discovery system revolving around authorities can add new perspectives
| 23 | Authority control and semantic interoperability | November 18, 201321
I see some far-reaching
opportunities!
