Semantic Web

In addition to the classic “Web of documents” W3C is helping to build a technology stack to support a “Web of data,” the sort of data you find in databases. The ultimate goal of the Web of data is to enable computers to do more useful work and to develop systems that can support trusted interactions over the network. The term “Semantic Web” refers to W3C’s vision of the Web of linked data. Semantic Web technologies enable people to create data stores on the Web, build vocabularies, and write rules for handling data. Linked data are empowered by technologies such as RDF, SPARQL, OWL, and SKOS.

Linked Data Header link

The Semantic Web is a Web of data — of dates and titles and part numbers and chemical properties and any other data one might conceive of. RDF provides the foundation for publishing and linking your data. Various technologies allow you to embed data in documents (RDFa, GRDDL) or expose what you have in SQL databases, or make it available as RDF files.

Vocabularies Header link

At times it may be important or valuable to organize data. Using OWL (to build vocabularies, or “ontologies”) and SKOS (for designing knowledge organization systems) it is possible to enrich data with additional meaning, which allows more people (and more machines) to do more with the data.

Query Header link

Query languages go hand-in-hand with databases. If the Semantic Web is viewed as a global database, then it is easy to understand why one would need a query language for that data. SPARQL is the query language for the Semantic Web.

Inference Header link

Near the top of the Semantic Web stack one finds inference — reasoning over data through rules. W3C work on rules, primarily through RIF and OWL, is focused on translating between rule languages and exchanging rules among different systems.

Vertical Applications Header link

W3C is working with different industries — for example in Health Care and Life Sciences, eGovernment, and Energy — to improve collaboration, research and development, and innovation adoption through Semantic Web technology. For instance, by aiding decision-making in clinical research, Semantic Web technologies will bridge many forms of biological and medical information across institutions.

FREME  is a project that is developing a  Framework  for multilingual and semantic enrichment of digital content. A key aspect of the framework is that it puts standards and best practices in the area of  linguistic linked data  and multilingual content processing in action. We will introduce the framework in a dedicated webinar on 22 February, 4 p.m. CET. If you are interested in participating please contact  Nieves Sande  and  Felix Sasaki for further logistics.

This tutorial workshop, sponsored by the Unicode Consortium and organized by the German University of Technology in Muscat, Oman, is a three-day event designed to familiarize the audience with the Unicode Standard and the concepts of internationalization. It is the first Unicode event to be held in the Middle East.

The workshop programincludes an introduction to Writing Systems & Unicode, plus presentations on Arabic Typography, web best practices, mobile internationalization, and more.

The workshop websiteprovides full information about the event. Early bird registration lasts until January 31, 2016, but register early to ensure a place.

This video  explains what Linguistic Linked Data is and summarizes the outcomes of the  LIDER project . This includes best practices for working with Linguist Linked Data, a reference architecture and a roadmap for future activities around Linguistic Linked Data. The video has been produced by the LIDER project and has been published during the  European Data Forum 2015 event.

The Internationalization Working Group has published a First Public Working Draft of Internationalization Best Practices for Spec Developers.

This document provides a checklist of internationalization-related considerations when developing a specification. Most checklist items point to detailed supporting information in other documents. Where such information does not yet exist, it can be given a temporary home in this document. The dynamic page Internationalization Techniques: Developing specificationsis automatically generated from this document.

The current version is still a very early draft, and it is expected that the information will change regularly as new content is added and existing content is modified in the light of experience and discussion.

The  BPMLOD community group  has published three best practices for working with Multilingual Linked Data. The best practices are around  bilingual dictionaries multilingual dictionaries  and  multilingual terminologies. The BPMLOD group will continue to work on further best practices related to other types of language resources.

In the last two years, the  LIDER project  has organized several  roadmapping events  to gather a broad community around the topic of linguistic linked data. On October 20th 2015 LIDER will engage with two selected communities: linguistics and experts in digital humanities, via a national roadmapping workshop that will take place in Spain. The  7th LIDER roadmapping workshop  will focus on these topics and will be held in Madrid at Universidad Politécnica de Madrid. The participation will be free and open. Spanish will be the main language of the event. For more information also about participation please visit the workshop website  http://lider-project.eu/workshopMadrid/

A report summarizing the MultilingualWeb workshop in Riga is now available from the MultilingualWeb site. It contains a summary of each session with links to presentation slides and minutes taken during the workshop in Riga. The workshop was a huge success. With the parallel Connecting Europe Facility (CEF) event, it had more than 200 registered participants. See a summary of highlights , and a dedicated report about outreach activities of the supporting EU funded LIDER project . The Workshop was locally organized by Tilde , sponsored by the LIDER project and by Verisign . Learn more about the Internationalization Activity.

Character Model for the World Wide Web: String Matching and Searchingbuilds upon Character Model for the World Wide Web 1.0: Fundamentals to provide authors of specifications, software developers, and content developers a common reference on string identity matching on the World Wide Web and thereby increase interoperability.

This new version introduces numerous editorial changes as well as replacing some temporary terminology with better terms, and integrating the case folding text from the string matching algorithm into the case folding section. The document template was also adapated to match the new Internationalization publication process. See details of changes.

In the last 1 1/2 years, the LIDER project has organized several roadmapping events to gather a broad community around the topic of linguistic linked data. In July this year, LIDER will engage with two selected communities. On July 6, the 5th LIDER roadmapping workshop will be held in Rome at Sapienza University of Rome . The topic will be cross-media linked data and the event will provide several high level speakers from the multimedia area. On July 13th LIDER will organize the 6th roadmappping workshopin Munich. The event will be hosted by Siemens and will focus on content analytics and linked data in healthcare and medicine.

For both workshops participation is limited. If you are interested in the Rome event please contact Tiziano Flati , for Munich please contact Philipp Cimiano.

    Spatial Data on the Web Working Group Face to Face meeting

    Amersfoort, Netherlands

    Hosted by Geonovum

    The Spatial Data on the Web Working Group, for which W3C is collaborating closely with the Open Geospatial Consortium (OGC) will meet at Dutch geospatial standards body, Geonovum's offices. The 2 day F2F will be followed by a Spatial Data on the Web Event, open to all, on Wednesday 10th.

    In the last two decades, location data has undergone many evolutions, due among other reasons to the development of the web. Many initiatives, related to the theme of Geodata on the Web, are currently on the go. This event will discuss the latest state of the art, both from the GIS perspective as well as the Web world. We bring together the Linked Data and GIS communities for a fruitful discussion of current and future steps to be taken.
