Pellet 2.0 RC7: The SemTech 2009 Release In anticipation of our Pellet tutorial at the Semantic Technology Conference next week, we 19ve made a new release candidate for Pellet 2.0 available for download. Pellet 2.0 RC7 improves on previous releases by resolving several exception-causing bugs reported by users, improving the lint …
- New Common Tag Format
New Common Tag Format Today we are announcing our support of Common Tag, a new semantic tagging format for Web pages. Developed jointly by a group of Web companies including Zemanta, Metaweb, and Yahoo!, the Common Tag format adds semantic meaning to tags, making Web content more discoverable and enabling …
- The BBC, the Graph, and Linked Data Stores
The BBC, the Graph, and Linked Data Stores Over the past few weeks, Talis has been working with the BBC to crawl their programmes and music sites and pull in a bunch of usable data into a Platform store. This store now contains information on over 360,000 programmes and more …
- Semantic Wikis in the Enterprise – Sanjiva Nath
Semantic Wikis in the Enterprise – Sanjiva Nath I consider myself firstly a fan and evangelist of semantic wikis and secondly a provider of technologies and solutions that offer those capabilities to enterprises. After spending several years following technologies related to this particular feature, on the eve of the Semantic …
Alex Iskod has an insightful blog post on Semantic Web: What is the Killer App that starts off a great conversation.
Before we talk about the Killer App for the Semantic Web, let us first look at some killer apps for the current Web. What do you think it is?
- Open Information repositories like Wikipedia?
- Social Networks?
- Hosted Applications?
- Social Resources (bookmarks, pictures, videos)?
- <add your favorite app here>
Depending on where you are coming from, it could be any of these or a combination. The killer app varies with time and evolution of the web. But when the web started, what got people excited was the easy accessibility of information. Even the static web served useful purpose before the dynamic web and web applications showed up.
I think the same thing is going to be true of The Semantic Web. I look at the Semantic Web as a set of incremental improvements over the current web.
Here is a rather simplistic view of the Semantic Web:
- More accessible data (some of it encoded with Microformats or RDFa or some yet to be invented markup format)
- Better associations (type) between items of information (Linked Data?)
Most of the data on the web comes from either documents or databases. Database data already has a lot of semantics associated with it (in the form of meta data) and links (in the form of foreign key relationships or symbolic keys). Somewhere along the journey from this more structured form to the display format (html), some of the valuable information is lost. How difficult is it to add this information back (in the form of semantic markup) to the display data?
Documents will evolve to have more structure too. With ODF, OOXML and other similar formats, you are more likely to see better structured documents. As web pages are widgetized, you will see richer types of data on the web pages.
Structured data and richer data and more accessible data will take us several steps forward. Once we have data that makes more sense to people and programs, we will start noticing several useful applications.
What is Semantic Web? Why do we need it? What can we do with it? This cool video (about 7 minutes) offers the simplest description and covers a few aspects of the semantic web. We need more of these.
- Semantic Web is a layer on the existing web
- By adding additional data (referred to as metadata), applications can derive more meaningful data from the web
- It is a way to connect people and data
Eyal Oren also talks about the project he is working on – Semantic Desktop. Most of the existing semantic web literature focuses on how it works, the underlying technologies (like RDF, OWL). So it is nice to have a video where you get a non-technical explanation of what it is and what you can get out of it. Hope DERI will produce more of these videos.

Yesterday I watched the this video Making Sense of the Semantic Web by Nova, a presentation at NextWeb conference. It talks about a lot more about the third generation of Web (3.0) and applications of Semantic Web with a brief description of underlying technologies. If you don’t like the term Semantic Web and want to pick another, Nova suggests “The Data Web”. While the current web is like a file system, the Semantic Web is a like a database, says Nova. Definitely worth watching this video. Nova suggests FOAF and SIOC as the starting points if you want to dip your toes into Semantic Web applications.
SMOB is a distributed / decentralised microblogging system built on RDF and Semantic Web technologies, mainly SIOC and FOAF
The SMOB client enables you to publish your microblog postings. It provides a web interface for entering new postings, stores the postings, and lets the aggregators of your choice know of each new posting.
The SMOB client complements the SMOB server, which lets you set up your own microblog aggregators.
