True KnowledgeTrue 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.

FreebaseAt ISWC2008 Freebase released its new RDF service for generating RDF representations of Freebase topics, allowing Freebase to be used as Linked Data! To obtain the RDF data for a topic send a GET request to http://rdf.freebase.com/rdf/some.topic.id where "some.topic.id" is replaced by the desired topic identifier (slashes in the identifier must be replaced by dots). Topic data can be represented as N3, RDF/XML or Turtle depending on the preferences expressed in your client's HTTP Accept header. Try it out with the Freebase topic Semantic Web.

Cross-Pollinating DBpedia and FreebaseNow that Freebase is available as Linked Data a big question that comes to mind is whether these two major projects will move to assimilate one another. DBpedia and Freebase – two endeavors primarily focused on curating unstructured and semi-structured data about everything and releasing it back into the wild (with structure) – get the bulk of their information from Wikipedia, so the amount of topical overlap is assumed to be extremely high. DBpedia gains new information when it extracts data from the latest Wikipedia dump, whereas Freebase, in addition to Wikipedia extractions, gains new information through its userbase of editors.

The Seesaw Effect of Algorithms vs. DataOver the years I've noticed that the importance of algorithms and data tends to shift back and forth, depending on which at the time is hardest to duplicate (often from a business perspective). This effect seems to be caused by the availability or demand of one side increasing or decreasing, shifting the balance of importance to the other. At one point the world of software was dominated by the proprietary. The organization with the best software (backend, algorithms, etc) was the dominant entity and data (from say, a Web 2.0 perspective) was generally not the focus. This may have partly been the responsibility of a mindset formed during an era with very little storage space and before mass user activity on the Web.

DBpedia concepts with corresponding photo collections from Christian Becker's Flickr Wrappr are now accessable by following the dbpedia:hasPictureCollection property. This means an additional 30-50 million photos are accessible through DBpedia.

For each of the 1.95 million DBpedia concepts, Flickr Wrappr generates a collection of Flickr photos that depict the concept. The DBpedia project never ceases to amaze me! Check out their entry for examples and more information.

Update: Paul Miller from Talis updated me with some new information.

Talking with TalisI just recently stumbled upon Talking with Talis, a blog by Talis that hosts podcasts they've created from interviews with various people in the Semantic Web community. In their archives you can find nearly 60 podcasts, and this number is growing. The podcasts are fairly lengthy too, with most ranging between a half-hour to an hour long. For convenience and reference, each podcast entry lists the sites they talk about during the conversation, which makes following along easier.

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.

FreebaseFreebase stores millions of entities and assertions about nearly every topic one can ponder (thanks are owed to their seed dataset – Wikipedia – and their amazing community). The amount of information that Freebase stores is incredible, and is a testament to what can be accomplished with the help of a dedicated community and a little (or a lot) of clever software engineering.
