Plateau?

Gartner’s hype cycle

Morphology of Plateau• Research to bridge the gap between theory

and application.

• Real world application needs could be interesting research directions.

• Expectations are higher than used to -evaluation of the added value to the status quo.

Hypermedia. Ruben Verborgh, 2014

• Leveraging The Consumption of Linguistic Open Data for Educational Purposes. Antonio J. Roa-Valverde, 2015

Serendipitous Web Applications through Semantic Hypermedia

“… to enable a new generation of intelligent Web clients through hypermedia and semantics, enabling a

more serendipitous Web…”

“How can semantic hypermedia improve the serendipitous reuse of data and applications on the

Web?”

Ruben Verborgh

Leveraging the consumption of Linguistic Open Data for Educational Purposes

“we exploit the practical dimension of Wiktionary”

“…with our educational use case, we show how our research can be put in practice in the context of a

mobile application designed exclusively for supporting users in the acquisition of new foreign second

language (FSL) vocabulary.”

Antonio J. Roa-Valverde

A Common API for Linked Data Entity Summaries

“We introduce SUMMA, an API definition that enables to decouple generation and presentation of

summaries. It enables multiple consumers to retrieve summaries from multiple providers in a

unified and lightweight way.”

Andreas Thalhammer

Leveraging Websites to APIs using Semantics

“helps to identify the most appropriate set of LOV vocabulary terms for a given webpage by leveraging the existing dynamics within the LOV graph and the

usage patterns in the LOD cloud.”

“…an online service endpoint, which can be used by developers and ontology engineers…”

Industry

• BBC(linked data platform, bbc.co.uk/things)

• Google(schema.org, knowledge graph, email markup)

• Facebook(graph search, FAIR)

BBC

• Dynamic Semantic Publishing Framework provided by Ontotext

- 800+ Dynamic pages generated through SPARQL for the World Cup 2010

- 2 million page requests/day

• Linked Data Platform

BBC Things

Knowledge graph

Google Email markup“Unlock the power of your emails with schema.org”

JSON-LD + schema.org actions

e.g. schema.org/RsvpAction that “extends” the schema.org/Action

schema.org

• Contract with the developers about the understandable metadata terms on the published web content

• Uptake: 17% of 15M domains according to the Common Web Crawler, Q4 2014

• Misuse of the vocabulary of some type >50%, Meusel et al. at ESWC 2015

Facebook AI Research

“…we plan to work openly with and invest in the AI research community in France, the EU, and beyond as

we strive to make meaningful progress in these fields. We have a collaborative agreement in place with INRIA…”

Facebook + INRIA

Best way to bridge the gap is to bring the two sides under the same roof.

Outlook

Problems

• Open Data portals with SPARQL endpoints. How many developers are able to use that?

• Is there enough prototypes using Semantic Technologies and/or consuming Open Data?

• Educate developers.

What to do?• Find broken parts in the funnel and fix them,

build a product, PhD, MSc, push a solution on github.

• Encourage research directions with practical applications.

• Providing data dumps or SPARQL endpoints does not help neither the Semantic Web per se, nor the real Web.

• Publish MOOC online courses.

What else to do?

• Understand and promote the realistic added valueof the Semantic Web technologies.

• Applied research.

• Solutions that push further the real world through the Web.

• Envision the next step for the Web.
