Today finally I logged in to Twine the first time. I was reading yesterday about some shortcomings of the system, so I was keen on trying out the system by myself to get my own impression.

It's true that the system isn't as easy to understand as del.icio.us or other bookmarking tools. It takes a while until you get used to all those additional ways you can navigate through the system. Remember: "Twine looks at content and parses it automatically for the names of people, places, organizations and other subject tags. Users are then able to navigate between related content, view recommended content and connect with recommended people with related interests."

Unlike traditional search engines, which crawl the Web gathering Web pages, Semantic Web search engines index RDF data stored on the Web and provide an interface to search through the crawled data. Below is a list of Semantic Web search engines that are currently under development.

The Calais Initiative is almost one month old, and they've already received a large and welcoming response from the development community (1,113 early adopters)! When they weren't busy doing interviews or answering hundreds of emails and forum posts, they were coming up with ways to help spread the technology. They will soon be releasing a Wordpress plugin, followed by plugins for Drupal, Plone and other content management systems. They also express that Calais is not only good for named entity extraction, but can extract other facts from documents. An example they give is "what technologies are associated with what company in a document?" Good luck, Calais team!

True Knowledge is a natural language search engine and question answering site, but to leave it at that would not do the site justice. What makes it stand out from similar sounding services like Powerset and Freebase? True Knowledge tackles natural language search and question answering (much like Powerset and Hakia), and it also maintains a knowledge base of facts about the world (similar to DBpedia and Freebase). However, what makes True Knowledge stand out is that they've combined these features and encourage their userbase to contribute facts and add new knowledge.

A lot of you emailed me asking where to find more videos, so I'm delivering the goods. I've expanded the previous list from a paltry 17 to a remarkable 302, and I've included podcasts this time! There were so many videos I had to break them up into different categories for easier skimming. There are no duplicates, however I did place some videos into more than one category when I felt it was appropriate. This list is monstrous, enjoy.

I've been hard at work on updating Semantic Focus, both from an articles standpoint as well as adding new features. Although larger, more hush-hush projects (Semantic Web/NLP related) loom on the horizon, I'd like to share with you a few changes you may have noticed around the blog, and how they are especially of benefit to our guest writers and other members of the Blogosphere.

To all my fellow Python enthusiasts, Ivan Herman (with the help of new programmers from the CTIC Foundation in Spain) has released a new version of his SPARQL wrapper for Python. The wrapper creates the query URI for you and will convert the results to RDF/XML and JSON, if possible. Keep up the excellent work guys, we can never have enough Semantic Web libs for Python!

Update: 302 Semantic Web Videos and Podcasts!

I've compiled a list of videos about the Semantic Web, RDF, and OWL for your viewing pleasure! Most of these videos are short, ranging from about 6 to 10 minutes while others are long (45+ minutes). Included are a few introductions, a few interviews, and a few that get into the gritty details.
