9 Semantic Search Engines That Will Change Search

by decembre
Here is a wrap up of some of the top semantic search engines which we’ve covered previously, and some updates on their research.

EyePlorer - Semantic - not a proper visual search engine (no search for any words or phrase) Give a visual representation for common, popular facts and suggest connections with other related facts and sources

by decembre
The service rather provides you with a visual representation for common, popular facts and suggest connections with other related facts and sources. All results displayed inside a colored wheel can be arranged onto a virtual notepad for later reading and sorted for relevance.

ARQ - Property Paths

by greut

A property path expression (or just 'path') is similar to a string regular expression but over properties, not characters. ARQ determines all matches of a path expression and binds subject or object as appropriate. Only one match is recorded - no duplicates for any given path expression, although is the path is used in a situation where it's initial points is already repeated in a pattern, then this duplication is preserved.

Introducing Operator, a Microformat Detection Extension for Firefox 2____Mozilla Labs - 2006

by decembre & 7 others , 2 comments
Operator demonstrates the usefulness of semantic information on the Web, in real world scenarios.Here are some examples of things you can do with this release of Operator, and with the Web as it exists today : Yahoo! Local and Your Address Book. With Operator you can send the phone number of your favorite pizza place from Yahoo! Local to your address book, without having to type anything..... Operator requires information on the Web to be encoded using microformats, and since this method for semantically encoding information is relatively new, not all sites are using microformats yet. However, Operator works great with any blog that uses rel-tag, and the sites Yahoo! Local, Flickr, and Upcoming.org, all of which contain millions of pieces of information expressed using microformats. As more sites begin to semantically encode data with microformats, Operator will automatically work with them as well.

Make your Data Web Friendly - W3C Q&A Weblog

by greut (via)

A Web language is not only a markup language (be XML, SGML or binary). For example, JPEG is not a Web format, but a format used on the Web. A Web format has the capability to play into the Web, it has linking capabilities.
