… if all agents publish its scholarly data as Linked (Open) Data
Publication is published N times...
… if N agents publish its scholarly data as Linked (Open) Data
Linked (Open) Data is generated with N different ways
Semantic Publishing
enhances the meaning of publications by enriching them with metadata
Semantic Publishing: ad-hoc solutions
different agents ownoverlapping or complementary scholarly data
use their own ad-hoc solutionsto generate and publish their own Linked (Open) Data
Semantic Publishing: fragmented datasets
different agents ownoverlapping or complementary scholarly data
focus on metadata or content, rarely on both
content annotations are rarely published as datasets
Semantic Publishing: currently leading to..
duplicate efforts for Linked (Open) Data generation:
(re-)implementing from scratch
non-negligible implementation & maintenance costs
Semantic Publishing: current
effort for Linked (Open) Data generation:
implementation & maintenance ↗
Semantic Publishing: our approach
effort for Linked (Open) Data generation:
implementation & maintenance ↘
model, semantic annotations, integration & cleansing ↗
How can we reduce implementation costsincrease Linked Data quality?
Semantic Publishing: our approach
general-purpose Linked (Open) Data generation and publication workflow
adjusted to each agent’s scholarly data
integrates metadata & content annotations
Semantic Publishing: iLastic
general-purpose Linked (Open) Data generation and publication workflowbased on our modular RML tool chain
adjusted to iMinds & Ghent university repositoryoverlapping and complementary scholarly data
integrates metadata & content annotationsbased on the RML tool chain & text enricher alignment
