Linked Data Publication and Interlinking Research within the SFI funded ADAPT Centre

  1. 1. Linked Data Publication and Interlinking Research within the SFI funded ADAPT Centre Christophe Debruyne - ADAPT, Trinity College Dublin, Dublin, Ireland christophe.debruyne@adaptcentre.ie 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. 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. 7/4/19 2
  3. 3. www.adaptcentre.ieSFI ADAPT Centre for Digital Content Technology Theme A: Understanding Global Content Theme B: Transforming Global Content Theme D: Interacting with Global Content Theme C: Personalizing the User Experience Theme E: Managing the Global Conversation 7/4/19 3 NLP and Machine Learning Multimodal Interaction And Search Translation Automation Personalization and AdaptivityData and Privacy Management
  4. 4. www.adaptcentre.ieTheme E • 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 à Led by Prof. Declan O’Sullivan 3. Data Governance and Data Value à Led by Dr. Rob Brennan 7/4/19 4
  5. 5. www.adaptcentre.ieNAISC 7/4/19 5 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 Provenance of Linked Data Interlinks for the Library Domain. WWW (Companion Volume) 2019: 954-958 • Lucy McKenna, Christophe Debruyne, Declan O'Sullivan: Understanding the Position of Information Professionals with regards to Linked Data: A Survey of Libraries, Archives and Museums. JCDL 2018: 7-16
  6. 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. 7/4/19 6
  7. 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 7/4/19 7 Interlinking method suitable for IPs User friendly GUI supporting method Provenance information GOAL
  8. 8. www.adaptcentre.ieNAISC Framework 7/4/19 8 Staging Characterization Mappings in Use Reuse Matching Align and Map The focus is on the creation and management of interlinks.
  9. 9. www.adaptcentre.ieNAISC Provenance Model 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 7/4/19 9

  14. 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? 7/4/19 14
