Linked Data
2
• Linked (Open) Data (LOD) is a set of best practices for
• exposing, sharing, and connecting pieces of data on the Semantic Web using URIs and RDF
• enabling interlinking and semantic queries
• providing machine readable contents
• LOD 5-stars

Semantic Publishing
5
• The knowledge management of scholarly and bibliographic products in the Semantic Web
• Aimed at
• contributing to the realisation of the Linked Data for scholarly products
• providing access to semantic enhanced scholarly products
• enabling a variety of tasks focused on the exploitation of scholarly data such as knowledge discovery, knowledge exploration and data integration.

SPAR in ST&DL
7
• SPAR ontologies form a suite of orthogonal and complementary ontology modules for
• creating machine-readable RDF metadata for bibliographic entities
• describing more complex information, such as publishing roles, rhetoric of citations, documents, etc.
• ST&DL uses SPAR ontologies as reference models for organizing and representing bibliographic data as LOD

• Exposes data as RDF via content negotiation
• Provides a SPARQL endpoint for querying
• data
• ontologies
• data+ontologies
• Will be available at data.stdl.cnr.it

ST&DL as LOD: tools
10
• SPARifier
• a framework for converting ST&DL non-RDF data to LOD
• MACJa: Metadata And Citations Jailbreaker
• processing PDF files in order to extract relevant semantic according to SPAR
• CiTalO
• automatic typing of citations wrt to CiTO ontology

Reusing Linked Data for similarity detection
11
• Recommendation system for bibliographic resources based on
• similarity detection by exploiting titles, abstracts and keywords
• an approach that relies on the semiotic indexing of resources
STLab ISTC - CNR
Enhancing content with Linked Data
12
• Enriching bibliographic resource by linking content with Linked Data
• data.stdl.cnr.it and external datasets
• Providing more advanced knowledge-oriented interactions
• improving exploration and user experience
• improving automatic reasoning

Ongoing work
13
• Opening of data.stdl.cnr.it
• Generating citation networks with citation types
• citations as tools for linking, disseminating, exploring, evaluating research
• Linking with other services, e.g.,
• DOI
• ORCID
• CrossRef
• ScienceDirect
• Adding social interaction
