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.

Swoogle describes itself as being the search engine for the Semantic Web. Swoogle crawls the web looking for RDF documents. At this time Swoogle offers the these services:
- Search ontologies and instance data
- Search terms (URIs that have been defined as classes and properties)
- Provide metadata of Semantic Web documents
- Support browsing the Semantic Web
- Archive different versions of Semantic Web documents

It seems as though nothing short of a new buzzword can stop the burst of activity in the vertical search market, and who are we to complain? Vertical search engines differ from their horizontal brethren (who attempt to index the Web as a whole) by focusing on a single topic or niche about which to index information from the Web. Often, a VSE can deliver results with much greater relevancy and accuracy than major horizontal players like Google, Yahoo, and Microsoft.
The discussion of semantic search has gradually become popular. Just not long time ago, semantic search was thought to be barely a little bit more than a dream. At present, optimistic researchers have started to believe its possibility in the near future. Very recently at Read/WriteWeb, Dr. Riza C. Berkan, the CEO of Hakia (a company declared to perform "semantic search"), posted an article about semantic search that attracted much attention. Despite of agreeing with the post, here are more thoughts about semantic search.
The more we use the Internet, the more we realize the necessity of finding new solutions to better organize the growing mass of information. Today we actually have a certain number of tools to add meaning to the information that we drop all over the Web. Adding a comprehensible meaning to computers, allowing them to help us better organize things. That's the big idea behind the Semantic Web, an idea which appears more and more obvious to us everyday. In this field, we already have many advanced technologies, starting with those offered by the W3C itself: XML, RDF, OWL, etc.
To begin with, there is a very simple idea: Websites should themselves indicate their changes to the search engines. I've already touched upon the subject in the previous part of this series, right now search engines have a reversed approach which consists of crawling the Web constantly looking for the slightest modification. Don't you think it's silly? Think about the number of Web pages to visit, imagine the cost to get the lowest frequency between each visit. Consequently, it seems difficult to consider the development of new search engines today. Nevertheless, the advent of the Semantic Web should lead to their multiplication, in a vertical way, while search engines are getting specialized more and more in specific fields.
While I am still waiting for an invitation from Twine (probably you too?) I have received one from Powerset - natural language search. Powerset obviously is a promising company (and is promising a lot), so I was excited when I was starting to play around with this new tool which still isn't available for the public.
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.

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.

I just stumbled upon a useful resource from Sindice (the Semantic Web search engine) called the Map of Data. The Map of Data lists sites that export their information via Microformats and embedded RDF (as well which format(s) the sites are using). Each site has been categorized and conveniently placed into lists. The categories include books, people, places, products and listings, social news, events, politics, and more. According to Sindice over 10 billion pieces of reusable information can already be found across 100 million pages.
