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

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
