In my keynote talk at the tenth SEMANTiCS conference, I wanted to make three points:
2014 is a terrific year …
What does success look like? I don't think we have to look very far to see it.
Semantic Web Technologies, including Linked Data, are proving successful in a wide range of areas.
A very simple example is the adoption of the DCAT vocabulary that allows portals like datos.gob.es and publicdata.eu to harvest metadata from distributed portals. See the relevant section of the report from the recent Share-PSI 2.0 workshop on uses of Open Data for Efficiency in Government for more and the EC's DCAT Application profile.
At the other end of the scale from simple data publication and harvesting are the life sciences.
OpenPHACTS, originally a research project, now a non-profit, has 470 million triples decribing pharmacological and chemical data (drawn from several open sources).
The Monarch Initiative has a wealth of information about model organisms, in vitro models, genes, pathways, gene expression, protein and genetic interactions, orthology, disease, phenotypes, publications, and authors with semantic similarity calculations that suggest novel relationships based on the information content of data descriptions.
Efforts like DNA Digest setting out to make vast amounts of genomic data available in a privacy-aware environment, perhaps using the eXframe platform developed largely by (commercial) Partners Healthcare company.
And, for the OWL specialists here in the room, you may be interested in the bioinformatics analyst post at Craig Venter's lab in La Jolla.
Linked Data is perfect for publishing and sharing data between government agencies, and for improving services based on that data.
Government users of Linked Data include the UN's FAO that publishes its long established AGROVOC thesaurus in 20 languages, including links/mappings to many other datasets including Chinese Agricultural Thesaurus, the US National Agricultural Library Thesaurus, Library of Congress Subject Headings and more.
Made possible by SKOS.
European Union's Publications Office publishes a growing set of authoritative lists as SKOS concept schemes. Those URIs will soon be dereferenceable and the schemes already offer all labels in 23 languages.
The study I contributed to on use of Linked Open Data in the Public Sector is published by the European Commission.
Most ambitous project is Sarven Capadisli's work on 270a Linked Dataspaces. That allows you to query across multiple datasets and see visualisations and analyses with all the SPARQL hidden away. Data includes that from:
OGC's interest goes well beyond GeoSPARQL. See, for example, their Geopatial Semantic Web Interoperability Experiment.
Hence planned joint OGC/W3C Working Group on spatial data.
Sincere thanks to the men and women who worked on updating RDF and SPARQL, on (finally) creating standards for triples, quads, TRiG, Turtle. To those working on LDP (almost complete).
And thanks to the people behind the master stroke of JSON-LD.
We already are, or soon will be, working on some of the gaps:
We have some problems around skills and tooling.
I referred to a number of W3C initiatives outside the Data Activity that I think are worth noting:
Just as tools like Callimachus are sold as application servers, not as Linked Data tools, I believe we need to make our services available to regular Web developers in their terms. SPARQL is always there, yes, but we should aim for smart servers that allow regular Web developers to do smart things easily without needing to know that what they're doing is traversing a graph.
I referred to Markus Lanthaler and Ruben Verborgh's work in the HYDRA Comunity Group in this regard as well their work with Pieter Colpaert work on Linked Data Fragments. Sören Auer talked about 'Open Watson' as a possible future project that matches these ideas around Smart Servers and Smart Clients
I'm looking forward to celebrating 20 years if success in 2024!
