Open The Door To Bringing Linked Data To Real-World Projects

ld1Linked Data: Structured Data on the Web is now available in a soft-cover edition. The book, authored by David Wood, Marsha Zaidman, Luke Ruth, and Michael Hausenblas, and with a forward by Tim Berners-Lee, aims to give mainstream developers without previous experience with Linked Data practical techniques for integrating it into real-world projects, focusing on languages with which they’re likely to be familiar, such as JavaScript and Python.

Berners-Lee’s forward gets the ball rolling in a big way, making the case for Linked Data and its critical importance in the web ecosystem:“The Web of hypertext-linked documents is complemented by the very powerful Linked Web of Data.  Why linked?  Well, think of how the value of a Web page is very much a function of what it links to, as well as the inherent value of the information within the Web page. So it is — in a way even more so — also in the Semantic Web of Linked Data.  The data itself is valuable, but the links to other data make it much more so.”

The topic has clearly struck a nerve, Wood believes, noting that today we are “at a point where structured data on the web is getting tremendous play,” from Google’s Knowledge Graph to the Facebook Open Graph protocol, to the growing use of the schema.org vocabulary, to data still growing exponentially in the Linked Open Data Project, and more. “The industry is ready to talk about data and data processing in a way it never has been before,” he continues. There’s growing realization that Linked Data fits in with and nicely complements technologies in the data science realm, such as machine learning algorithms and Hadoop, such that “you can suddenly build things you never could before with a tiny team, and that’s pretty cool….No technology is sufficient in and of itself but combine them and you can do really powerful things.”

Linked Open Data In Action In World War I Showcase Project

A fascinating project has been undertaken by the Partners of the Pan-Canadian Documentary Heritage Network (PCDHN): It’s a proof-of-concept showcase of using Linked Open Data visualizations for “Out of the Trenches.” This is a look at the First World War from the Canadian perspective: war songs, postcards, newspapers, photos, films, and these resources’ intersection with Canadian soldiers who fought in the war.

 

These digital resources from organizations such as McGill University, the Universities of Alberta, Calgary and Saskatchewan, and the Bibliothèque et Archives nationales du Québec have been linked through existing metadata provided in formats ranging from spreadsheets to MODS XML to RDF. Rather than reduce the metadata to a common subset, the approach was to maximize its use by moving to the “web of data” concept, so that the resources can be combined in different and unexpected ways, according to the proof-of-concept final report that was issued on the project.

The premise was to expose the metadata for these resources using RDF XML and existing published ontologies such as the Event Ontology, the Dublin Core Ontology and the Biographical Ontology, elements sets, vocabularies and resources like the Geonames geographical database to maximize discovery by the user community and contribute to the Semantic Web.

Announcing New sWebMap Component in JavaScript

Frederick Giasson recently announced “the release of the new sWebMap Semantic Component in JavaScript. This new mapping component is a standalone JavaScript application that can be integrated on any new or existing web sites and interact with an Open Semantic Framework (OSF) instance to search, browse, filter and display with geographically-located information on an interactive map.” Read more

MongoGraph One Ups MongoDB With Semantic Power

MongoDB has been gaining traction: 10gen, which began the MongoDB project and offers commercial MongoDB support services, said that for 2011 there was a 300 percent increase in Fortune 500 enterprise customers. The list included Disney, Viacom, HP and McKesson. The company also noted strong adoption in Europe including Telefonica and The National Archives. In all, 10gen reported that it ended 2011 with more than 400 commercial customers, with numerous large deployments scaling to 1,000 or more servers.

What makes MongoDB appealing to JavaScript programmers working with JSON objects at these and other organizations is its simplicity. If all that’s desired is to have an easy-to-use database where you can add or retrieve JSON objects – the main data type for Javascript developers – it remains an attractive option.

But Franz Inc. proposes an alternative for those who want more sophisticated functionality: Use the semantic power of its AllegroGraph Web 3.0 database to deal with complicated queries, via MongoGraph, a MongoDB API to AllegroGraph technology.

Day of the Dolphin: Swim In the Personalized Social Stream With Bottlenose

It’s the Day of the Dolphin. Bottlenose (previously known as Bottleno.se), which we initially covered here, moves out of stealth and into private beta mode. The service lassoes your Twitter, Facebook and Yammer streams, and drives real-time understanding and surfacing of personally relevant content so that you don’t have to read everything (not that you ever could!). It debuts with a new architecture for leveraging “crowd computing” for enabling scale and for creating more and more “semantic stream” smarts around the flood of information on social networks.

Nova Spivack and co-founder and CTO Dominiek ter Heide (formerly CTO of Cerego Japan who has long been tackling the issue of distilling interest profiles behind social streams) are the minds behind the service. Spivack has essentially referred to Bottlenose as everything, and more, that Twitter Annotations never was.
