­Sir Tim Berners-Lee the inventor of the Web says that Linked Data is making a huge change much like the invention of the World Wide Web itself and below are listed the ten products from 2009 which he and others picked out for special review.

First is the new search product, Google Search Options and Rich Snippets and as its name suggests it extracts “rich snippets” from structured content on helpful web pages and is using this data to open standards like RDFa and microformats to power the new snippets.

Feedly, launched in August 2008, claims it is a “magazine-like start page”, while outsiders labeled it as “an alternative interface for Google Reader”. A mini bar hovers at the bottom as one surfs through web blogs and integrates FriendFeed, Twitter, Mozilla’a Ubiquity and Google Search.

A Javascript plug-in for publishers, Apture adds background information to links via pop-ups which display when a user hovers or clicks on them. Because of the amount of multimedia packed in these pop-up Apture is considered sophisticated by readers. Other sites using Apture reveal the rich, contextual and relevant content.

Fourth is Zemanta, a semantic analysis real-time tool that plugs into blogging software and offers bloggers relevant photos, links and other resources. The API also continues to be used by web startups and impresses users.

The Calais web service, considered to be Thomson Reuters’ most significant update, is a tool kit of products which makes it possible for publishers to categorize their content as places, people, companies events, fact, and more. Calais 4.0 went even further and enabled publishers to include their content in Linked Data assets from the Internet Movie Database (IMDB), GeoNames,, Wikipedia and others.

The BBC Music Beta project is BBC’s ongoing effort to build semantically linked and annotated web pages about artists played on their radio stations. Enhanced collections of data are interrelated with the BBC Music Beta project allowing fans to explore links between artists they may not have previously known.

Glue’s technology allows users to browse across verticals sites like YouTube, Amazon, and Wikipedia with the idea that the users can recommend content or items across categories like books, music and movies.

Freebase is an open database of information that is semantically marked up and is all about what one can do with structured databases. It recently announced that it had published its 10 millionth topic in spite of the skepticism that it offered nothing new and was too much like Wikipedia.

DBpedia is one of the largest sources of Linked Data on the Web and essentially extracts information from Wikipedia and makes it available on the Web.

Tim Berners-Lee, mentioned above as the inventor of the Web, is currently using to help the British government access and take advantage of Linked Data on the internet.
