- Abstract
- Linkages between research outputs are crucial in the scholarly knowledge graph. They
include online citations, but also links between versions that differ according to
various dimensions and
links to resources that were used to arrive at research results. In current scholarly
communication systems
this information is only made available post factum and is obtained via elaborate
batch processing. In this
paper we report on work aimed at making linkages available in real-time, in which
an alternative,
decentralised scholarly communication network is considered that consists of interacting
data nodes that
host artifacts and service nodes that add value to artifacts. The first result of
this work, the "Event
Notifications in Value-Adding Networks" specification, details interoperability requirements
for the
exchange of real-time life-cycle information pertaining to artifacts using Linked
Data Notifications. In
an experiment, we applied our specification to one particular use-case: distributing
Scholix
data-literature links to a network of Belgian institutional repositories by a national
service node. The
results of our experiment confirm the potential of our approach and provide a framework
to create a
network of interacting nodes implementing the core scholarly functions (registration,
certification,
awareness and archiving) in a decentralized and decoupled way.

- Abstract
- Logic can define how agents are provided or denied access to resources, how to interlink
resources using mining processes and provide users with choices for possible next
steps in a workflow. These decisions are for the most part hidden, internal to machines
processing data. In order to exchange this internal logic a portable Web logic is
required which the Semantic Web could provide. Combining logic and data provides insights
into the reasoning process and creates a new level of trust on the Semantic Web. Current
Web logics carries only a fragment of first-order logic (FOL) to keep exchange languages
decidable or easily processable. But, this is at a cost: the portability of logic.
Machines require implicit agreements to know which fragment of logic is being exchanged
and need a strategy for how to cope with the different fragments. These choices could
obscure insights into the reasoning process. We created RDF Surfaces in order to express
the full expressivity of FOL including saying explicitly `no'. This vision paper provides
basic principles and compares existing work. Even though support for FOL is semi-decidable,
we argue these problems are surmountable. RDF Surfaces span many use cases, including
describing misuse of information, adding explainability and trust to reasoning, and
providing scope for reasoning over streams of data and queries. RDF Surfaces provide
the direct translation of FOL for the Semantic Web. We hope this vision paper attracts
new implementers and opens the discussion to its formal specification.
