Web 3.0

This portal is about transparency, open government and innovation. The European Commission Data Portal provides access to open public data from the European Commission. It also provides access to data of other Union institutions, bodies, offices and agencies at their request. The published data can be downloaded by everyone interested to facilitate reuse, linking and the creation of innovative services. Moreover, this Data Portal p

This viewer shows how information about thousands of object and action categories is represented across human neocortex. The data come from brain activity measurements made using fMRI while a participant watched hours of movie trailers.

Semargl is a modular framework for crawling linked data from structured documents. The main goal of project is to provide lightweight and performant tool without excess dependencies.

This is a list of publications about DBpedia Spotlight. We keep elsewhere a list of other papers that have used DBpedia Spotlight.

A triplestore is a purpose-built database for the storage and retrieval of triples,[1] a triple being a data entity composed of subject-predicate-object, like "Bob is 35" or "Bob knows Fred".

This wiki is for connecting the W3C communities (Web developers, implementers, people who make the W3C specifications). The W3C has a formal track for making standards specifications. The specs answer a lot of questions, but not all of them. The wiki is used by many communities such as the Open Web Platform and the Semantic Web. You might want to contribute to W3C work

The LDSpider project provides a web crawling framework for the Linked Data web. Requirements and challenges for crawling the Linked Data web are different from regular web crawling, thus the LDSpider project offers a web crawler adapted to traverse and harvest content from the Linked Data web.

RDF format transformations http://triplr.org/output/source-uri output-format is one of html, json, ntriples, rdf or turtle.  source-uri is like example.org/foo/bar

mnemoweb is a search engine ..

We want to make reading and discovering content on the net easier. We want to do this through our two simple principles. 1. Cut out the noise Bookmarks, saved articles, feeds -we've got all those on our browsers too, but how often do you really go back and read all the content you've saved? Right at the point of reading, you should be able to see topics that pique your interest and pull content on those topics instantly and without having to sift through tons of articles. 2. YOUR world. YOUR opinion. We strongly think that we CAN NOT, CAN NOT become a society of homogenized opinions. It's YOUR world and YOU should have a say in where you get your content from.

Semantic Web Application Platform - SWAP or, if you like, Semantic Web Area for Play... visiting RDF and all points west. working toward the SWELL langauge, MIT-LCS's advanced development prototyping of tools and langauges for the Semantic Web.

(former Google Refine) OpenRefine is a powerful tool for working with messy data, cleaning it up, transforming it from one format into another, extending it with web services, and linking it to databases like Freebase.

Cwm (pronounced coom) is a general-purpose data processor for the semantic web, somewhat like sed, awk, etc. for text files or XSLT for XML. It is a forward chaining reasoner which can be used for querying, checking, transforming and filtering information. Its core language is RDF, extended to include rules, and it uses RDF/XML or RDF/N3 (see Notation3 Primer) serializations as required.

The Web Science Trust (WST) is a charitable body with the aim of supporting the global development of Web Science  through a network of world class laboratories known as WSTnet . It is hosted by the University of Southampton. The origins of the Web Science Trust can be found in the Web Science Research Initiative (WSRI) which was established in 2006.

The Sematic Web Client Library represents the complete Semantic Web as a single RDF graph. The library enables applications to query this global graph using SPARQL- and find(SPO) queries. To answer queries, the library dynamically retrieves information from the Semantic Web by dereferencing HTTP URIs, by following rdfs:seeAlso links, and by querying the Sindice search engine. The library is written in Java and is based on the Jena framework.

The Data-gov Wiki is a project being pursued in the Tetherless World Constellation at Rensselaer Polytechnic Institute. We are investigating open government datasets using semantic web technologies. Currently, we are translating such datasets into RDF, getting them linked to the linked data cloud, and developing interesting applications and demos on linked government data.
