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.

In TwC, Paige oversees compliance of company policy for geographic, country-region and cultural requirements, establishing a new center of excellence for market and world readiness, globalization/localizability, and language programs, tools, resources and external community forums to reach markets across the world with the right local experience.

The Multilingual Web Workshop series brings together participants interested in the best practices, new technologies, and standards needed to help content creators, localizers, language tools developers, and others address the new opportunities and challenges of the multilingual Web. It will provide for networking across communities and building connections.

Registration for the Workshop is free, and early registrationis recommended since space at the Workshop is limited.

The workshop will be part of the Riga Summit 2015 on the Multilingual Digital Single Market. We are organizing the workshop as part of the Riga Summit to strengthen the European related community at large. Depending on the number of submissions to the MultilingualWeb workshop we also may suggest to move presentations to other days of the summit. For these reasons we highly recommend you to attend the whole Riga Summit!

There is still opportunity for individuals to submit proposals to speak at the workshop. Ideal proposals will highlight emerging challenges or novel solutions for reaching out to a global, multilingual audience. The deadline for speaker proposals is March 8, but early submission is strongly encouraged. See the Call for Participationfor more details.

This workshop is made possible by the generous support of the LIDERproject.

The 1st Summer Datathon on Linguistic Linked Open Data(SD-LLOD-15) will be held from June 15th to 19th 2015 at Residencia Lucas Olazábal of Universidad Politécnica de Madrid, Cercedilla, Madrid.

The SD-LLOD datathon will provide practical knowledge about Linguistic Linked Data. The event targets both industry and academia. Participants will learn how to migrate linguistic data and publish them as Linked Data on the Web. The datathon is organized by the LIDERproject and will include practical sessions, seminars on selected topics and hacking sessions. To register, participants are expected to submit a short description (no more than 500 words) of their work and the resources they plan to work with during the datathon.

The cost of the datathon is sponsored by the LIDER project, which includes accommodation and meals of participants. There will be an administrative fee of 50€ for registering in the datathon. A limited amount of travelling grants will be available for attendants from less-developed countries who cannot cover their trip with other funds. Registration will be closed on 15th March.

W3C announced today the 8th MultilingualWeb workshop in a series of eventsexploring the mechanisms and processes needed to ensure that the World Wide Web lives up to its potential around the world and across barriers of language and culture.

This workshop will be held 29 April 2015in Riga, Latvia, and is made possible by the generous support of the LIDER project . The workshop is part of the Riga Summit 2015 on the Multilingual Digital Single Market(27-29 April)

Anyone may attend all sessions at no charge and the W3C welcomes participation by both speakers and non-speaking attendees. Early registration is encouraged due to limited space.

Building on the success of seven highly regarded previous workshops, this workshop will emphasize new technology developments that lead to new opportunities for the Multilingual Web. The workshop brings together participants interested in the best practices and standards needed to help content creators, localizers, language tools developers, and others meet the challenges of the multilingual Web.

The Encoding specificationhas been published as a Candidate Recommendation. This is a snapshot of the WHATWG document, as of 4 September 2014, published after discussion with the WHATWG editors. No changes have been made in the body of this document other than to align with W3C house styles. The primary reason that W3C is publishing this document is so that HTML5 and other specifications may normatively refer to a stable W3C Recommendation.

Going forward, the Internationalization Working Group expects to receive more comments in the form of implementation feedback and test cases. The Working Group
believes it will have satisfied its implementation criteria no earlier than 16 March 2015. If you would like to contribute test cases or information about implementations, please send mail to www-international@w3.org.

The utf-8 encoding is the most appropriate encoding for interchange of Unicode, the universal coded character set. Therefore for new protocols and formats, as well as existing formats deployed in new contexts, this specification requires (and defines) the utf-8 encoding.

The other (legacy) encodings have been defined to some extent in the past. However, user agents have not always implemented them in the same way, have not always used the same labels, and often differ in dealing with undefined and former proprietary areas of encodings. This specification addresses those gaps so that new user agents do not have to reverse engineer encoding implementations and existing user agents can converge.

The agenda of the 4th LIDER roadmapping workshop and LD4LT eventhas been published. A great variety of industry stakeholders will talk about linked data and content analytics. Industry areas represented include content analytics technology, multilingual conversational applications, localisation and more.

The workshop will take place on September 2nd in Leipzig, Germany and it will be collocated with the SEMANTiCS conference . The workshop will be organised as part of MLODE 2014 and will be preceded by a hackathonon the 1st of September.

The event is supported by the LIDER EU project, the MultilingualWeb community, the NLP2RDF project as well as the DBpediaproject.

A report summarizing the MultilingualWeb workshop in Madrid 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 Madrid. The workshop was a huge success, with approximately 110 participants, and with the associated LIDER roadmapping workshop . The Workshop was hosted by Universidad Politécnica de Madrid , sponsored by the EU-funded LIDER project, by Verisign and by Lionbridge.
A new workshop in the MultilingualWeb series is planned for 2015.

This documentbuilds upon on the 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 matching on the World Wide Web and thereby increase interoperability. String matching is the process by which a specification or implementation defines whether two string values are the same or different from one another.

The main target audience of this specification is W3C specification developers. This specification and parts of it can be referenced from other W3C specifications and it defines conformance criteria for W3C specifications, as well as other specifications.

This version of this document represents a significant change from its previous edition. Much of the content is changed and the recommendations are significantly altered. This fact is reflected in a change to the name of the document from “Character Model: Normalization” to “Character Model for the World Wide Web: String Matching and Searching”.
