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.

Language Tags and Locale Identifiers for the World Wide Webdescribes the best practices for identifying or selecting the language of content as well as the the locale preferences used to process or display data values and other information on the Web. It describes how document formats, specifications, and implementations should handle language tags, as well as extensions to language tags that describe the cultural or linguistic preferences referred to in internationalization as a “locale”.

Changes in this update include the following: All references to RFC3066bis were updated to BCP 47 or to RFC5646 or RFC 4647 as appropriate.References to HTML were changed to point to HTML5. Imported and rewrote the text formerly containing in Web Services Internationalization Usage Scenarios defining internationalization, locale, and other important terms. Modified and reorganized the other sections of this document. Moved the Web services materials to an appendix.

The LIDER project is fostering the creation of a community around Linguistic Linked Data (LLD): linked data used to represent metadata about linguistic resources and the resources themselves, e.g. lexica, thesauri, corpora, multilingual semantic networks etc. In a dedicated  LD4LT  community group call on 2 April,  3 p.m. CEST , we will discuss how LLD can contribute to the creation of the digital single market. See for more details the  slides that will be presented during the call.

The call is open to the public, no LD4LT group participation is required. Dial-in informationis available. No knowledge about linguistic linked data is required.

See the program . The keynote speaker will be Page Williams, Director of Global Readiness, Trustworthy Computing, Microsoft. She is followed by a strong line up in sessions entitled Developers and Creators, Localizers, Machines, and Users, including speakers from Microsoft, the European Parliament, the UN FAO, Intel, Verisign, and many more. The workshop is made possible with the generous support of the  LIDER project.

Participation in the event is free. Please register via the  Riga Summit for the Multilingual Digital Single Market site.

The MultilingualWeb workshops, funded by the European Commission and coordinated by the W3C, look at best practices and standards related to all aspects of creating, localizing and deploying the multilingual Web. The workshops are successful because they attract a wide range of participants, from fields such as localization, language technology, browser development, content authoring and tool development, etc., to create a holistic view of the interoperability needs of the multilingual Web.

We look forward to seeing you in Riga!

The LIDER project is  developing  LingHub , a repository of metadata about language resources and linguistic data. During a dedicated  conference call on 19 March, 3 p.m. CET , LingHub will be discussed in the  LD4LT community group  to gather feedback from the public at large. The call is open to the public, no LD4LT group participation is required. Dial-in information is available. The call will be relevant for anybody interest specifically in language resources, or in public metadata repositories and the  re-use of public sector information in general.

The Unicode® Consortium announced the start of the beta review for Unicode 8.0.0, which is scheduled for release in June, 2015. All beta feedback must be submitted by April 27, 2015.

Unicode 8.0.0 comprises several changes which require careful migration in implementations, including the conversion of Cherokee to a bicameral script, a different encoding model for New Tai Lue, and additional character repertoire. Implementers need to change code and check assumptions regarding case mappings, New Tai Lue syllables, Han character ranges, and confusables. Character additions in Unicode 8.0.0 include emoji symbol modifiers for implementing skin tone diversity, other emoji symbols, a large collection of CJK unified ideographs, a new currency sign for the Georgian lari, and six new scripts. For more information on emoji in Unicode 8.0.0, see the associated draft Unicode Emoji report.

Please review the documentation, adjust code, test the data files, and report errors and other issues to the Unicode Consortium by April 27, 2015. Feedback instructions are on the beta page.

See more information about testing the 8.0.0 beta. See the current draft summaryof Unicode 8.0.0.

The LIDER project is developing a reference architecture for working with Linguistic Linked Data (LLD). LLD is linked data used to represent metadata about linguistic resources and the resources themselves, e.g. lexica, thesauri, corpora, multilingual semantic networks etc. The reference architecture defines various aspects of LLD processing, related e.g. to LLD publishing, linking, services or discovery. As part of this activity, the LD4LT community group is organizing a conference call on 5 March, 3 p.m. CET, to gather feedback from the public at large.

The call is open to the public, no LD4LT group participation is required. Dial-in informationis available. No knowledge about LLD is required. We especially are interested in feedback from potential users of LLD in content analytics related application areas.
