June 26th, 2019 @ LIBER LOD Workshop 2019
The ADAPT Centre is funded under the SFI Research Centres Programme (Grant 13/RC/2106) and is co-funded under the European Regional Development Fund.

2. www.adaptcentre.ieSFI ADAPT Centre for Digital Content Technology
• Supported by Science Foundation Ireland, ADAPT combines the
expertise of researchers at four universities (TCD, DCU, UCD, and
TU Dublin). ADAPT engages with over 140 organizations to
produce ground-breaking digital content innovations.
• The ADAPT Research Centre focuses on developing next
generation digital technologies that aim to enhance people’s
lives by helping to analyse, personalise and deliver digital data
more effectively for businesses and individuals.
• ADAPT research and technologies enable businesses in all
sectors to harness global digital content and media technologies
to achieve unprecedented customer and community
engagement.

• Within Theme E address the integration, management and
optimization of privacy-aware data flows between users
and content services.
• There are 3 “strands” within the theme:
1. Content Metadata for Privacy Management
à Led by Prof. Dave Lewis
2. Data Integration Mappings: User Interaction and
Continuous Management

NAISC – pronounced noshk – stands for Novel Authoritative
Interlinking of Schema and Concepts.
The work of Lucy McKenna – PhD student at the ADAPT
Currently given a presentation in another session, but at LIBER.
The remainder of the talk will be mostly about her research.
Based on:
• Lucy McKenna, Christophe Debruyne, Declan O'Sullivan: NAISC: An
Authoritative Linked Data Interlinking Approach for
the Library Domain. JCDL 2019 (to appear)
• Lucy McKenna, Christophe Debruyne, Declan O'Sullivan: Modelling the

6. www.adaptcentre.ieLibraries and Linked Data
• Using Linked Data (LD) could improve the discoverability,
searchability and interoperability of library data.
• Uptake of LD in libraries is relatively slow.
• Developed a LD interlinking approach for the library
domain.
• Aim: to improve LD interlinking accessibility for Information
Professionals (IPs) such as librarians, archivists and
cataloguers.

7. www.adaptcentre.ieLD Survey for Information Professionals
• Online questionnaire - 50 Questions - 185 participants
• Distributed to libraries, archives and museums.
• Challenges identified included:
• Lack of LD provenance data
• Technologically complex LD tooling
• LD tooling does not meet requirements of library
• Difficulty interlinking and integrating data

Competency question driven ontology engineering
• Adoption of the PROV-O ontology
• Minimal extension
– introduction of
classes for NAISC
specific entities
and activities
• Prescription of
knowledge
organization –
clever use of
named graphs

14. www.adaptcentre.ie( Lucy’s) Future work
• Refine method and tool based on feedback, and conduct a
final experiment.
• Investigate how named graphs and RDF* affect IPs.
How does this work fit in Theme E’s wider research agenda
on Linked Data publishing and interlinking?
