Here are the eight shiny, new things I learned at last week's Web 2.0 Expo, and why they signal the end of the world as we know it.

I spent much of the early part of last week at the big Web 2.0 Expo in San Francisco. Unlike prior Web 2.0 events—where a small core of tech leaders met to plan the revolution—10,000 foot soldiers showed up to learn how to win the war. It reminded me of some of the early Internet shows of the mid-'90s, or the Windows conferences before that. I learned a lot, particularly about some of the new terms and new ways people are building these new-age businesses. Here, in no particular order, are some of the new ideas that the Web 2.0 army are talking about.
What are the best 100 Web 2.0 sites and services? We don't know. But you do.
The Webware 100 will be the 10 best sites in 10 categories, chosen by Webware's readers. The first step to picking the winners is nominating candidates to vote on. Use the form below to enter a site into the awards program. You may come back to enter more. Deadline is May 7.
After nominations have closed, voting for the winners will begin. Click here to learn more.
Likewise, Microsoft, Cisco and several others have added video to their enterprise focused products. This converged view of communications is one of the reasons why Google has acquired video conferencing software from Swedish start-up, Marratech. On the blog Douglas Merrill, VP Engineering at Google says:
As a company, we thrive on casual interactions and spontaneous collaboration. So we’re excited about acquiring Marratech’s video conferencing software, which will enable from-the-desktop participation for Googlers in video conference meetings wherever there’s an Internet connection.
Whether you use your computer for work or fun, the programs you use generally have one thing in common - they are stored on your PC. Increasingly though, that software is moving online.
The move to put more and more of those familiar programs on to the web has been happening for a while but its latest incarnation has won the name of Web 2.0.
What is it - the definition is imprecise at best, but it loosely describes a category of websites that are known for interactivity, collaboration and community.
I had blogged about BookmarkAll.com sometime back and the advantages bookmarking online as opposed to bookmarking on a browser.
Well, this online bookmarking service has added some great new features. I wanted to inform you guys about their "RSS Topic" feature. For those who are not aware "Really Simple Syndication" or RSS refers to the way blogs or web sites to share their current posts, news or headlines via a frequently updated xml file.
Now users who are registered with Bookmarkall.com can bookmark RSS feeds, according to groups you frequently visit (e.g., news, web design, etc.). just like other regular bookmarks. A user can have unlimited topics.
If I am not mistaken, this is the first online bookmark manager to provide an RSS bookmark service. This presents greater convenience - you can access your favourite RSS feeds from anywhere in the World with an internet access. Besides, there are several security advantages of using their service for online bookm
Semantics (Greek semantikos, giving signs, significant, symptomatic, from sema, sign) refers to the aspects of meaning that are expressed in a language, code, or other form of representation. Semantics is contrasted with two other aspects of meaningful expression, namely, syntax, the construction of complex signs from simpler signs, and pragmatics, the practical use of signs by agents or communities of interpretation in particular circumstances and contexts. By the usual convention that calls a study or a theory by the name of its subject matter, semantics may also denote the theoretical study of meaning in systems of signs
DBin is a Semantic Web application that enables groups of users
with a common interest to cooperatively create semantically
structured knowledge bases. These user groups, which we call
“Semantic Web Communities”, are made possible by creating
customized user environments called “Brainlets”. Brainlets
provide user interfaces and domain specific tools (e.g. querying,
viewing and editing facilities) which enable community
participants to interact with the data of interest. Brainlets are
directly created by domain experts using an XML description
language. DBin clients communicate and exchange annotations
using a P2P infrastructure. Access control and digital signatures
put by DBin inside the authored RDF enable trust and information
filtering. In this paper we show a specific use case where a
“Semantic Web Community” is created to enable a group of users
to share their del.icio.us tags and organize them into a
cooperatively built RDFS ontology.
Tim Berners-Lee confirmed as plenary speaker
Tim Berners-Lee is the Director of the World Wide Web Consortium, a Senior Researcher at MIT where he leads the Decentralized Information Group, and a Professor of Computer Science at University of Southampton. While working at CERN, the European Particle Physics Laboratory, he invented the World Wide Web. It was there where he wrote the first Web client (a combination of browser and editor) and the first Web server. His original specifications of URLs, HTTP and HTML were widely adopted and refined as Web technology spread. In 2001 he became a fellow of the Royal Society, and more recently he received the 2007 Charles Stark Draper Prize, given by the National Academy of Engineering (US). His plenary talk will take place on Wednesday May 9 at WWW2007.

From our point of view the Semantic Web stack currently is used as follows: (cf. Fig. 1):
The Semantic Web Stack with Multimedia Metadata and Web Service descriptions
Fig. 1.: The Semantic Web Stack with Multimedia Metadata and Web Service descriptions.
Where (from bottom up):
* The two lowest layers, i.e. Unicode for a platform-neutral encoding and XML for the platform-neutral document representation are common to all (Semantic) Web applications
* Above the XML layer we have a rough distinction in the multimedia aspect and the Web Service aspect:
o On the Semantic Web/Multimedia tower we have both MPEG-7 and RDF/OWL for representing low and high-level features, possibly extended by rules
o On the Semantic Web/Services tower we have either the RDF/OWL/OWL-S-based branch or the WSML-based branch, both grounded on WSDL, again possibly using rules on the highest level.

Next Generation CiteSeer (CiteSeerx)
The Next Generation CiteSeer, CiteSeerx, project has been started with funding from the National Science Foundation and Microsoft Research. This project will take CiteSeer to the next level as a search engine and digital library. As an example, research underway expands CiteSeer's notion of "contribution" to acknowledgments in addition to citations, which would make it the first automatically generated acknowledgment index. A beta version is currently available at the CiteSeer site.
