What is Web 3.0 ?

Web 3.0 is one of the terms used to describe the evolutionary stage of the Web that follows Web 2.0.

Nova Spivack defines Web 3.0 as the third decade of the Web (2010-2020) during which he suggests several major complementary technology trends will reach new levels of maturity simultaneously including:

1. transformation of the Web from a network of separately siloed applications and content repositories to a more seamless and interoperable whole.
2. ubiquitous connectivity, broadband adoption, mobile Internet access and mobile devices;
3. network computing, software-as-a-service business models, Web services interoperability, distributed computing, grid computing and cloud computing;
4. open technologies, open APIs and protocols, open data formats, open-source software platforms and open data (e.g. Creative Commons, Open Data License);
5. open identity, OpenID, open reputation, roaming portable identity and personal data;
6. the intelligent web, Semantic Web technologies such as RDF, OWL, SWRL, SPARQL, GRDDL, semantic application platforms, and statement-based data stores;
7. distributed databases, the “World Wide Database” (enabled by Semantic Web technologies); and intelligent applications, natural language processing, machine learning, machine reasoning, autonomous agents.

Research under Spivack's definition

Transformation: Web 1.0 was "read-only", Web 2.0 is "read-write", and Web 3.0 will be "read-write-execute".

Network computing: Web 3.0 could be the realization and extension of the Semantic web concept. Academic research is being conducted to develop software for reasoning, based on description logic and intelligent agents.

Distributed databases: The first step towards a "Web 3.0" is the emergence of "The Data Web" as structured data records are published to the Web in reusable and remotely queryable formats, such as XML, RDF, Website Parse Template and microformats.

Intelligent applications:Web 3.0 has also been used to describe an evolutionary path for the Web that leads to artificial intelligence that can reason about the Web in a quasi-human fashion.

3D spaces: Another possible path for Web 3.0 is towards the 3 dimensional vision championed. This would involve the Web transforming into a series of 3D spaces

Socio-technological research: Web 3.0 is "the biological, digital analog web where information is made of a plethora of digital values coalesced for sense and linked to the real-world by analog interfaces.

How is Yahoo! different/similar to Google marketing?

Billing

Yahoo! Sponsored Search allows advertisers to decide on the maximum amount they want to pay for every click that their ad gets. It sets a minimum account balance and sends you a bill when that amount has been reached—which may mean multiple charges each month.

Google Adwords has no minimum spending requirement. It accumulates advertising clicks and sends you a bill every month.

Keywords feature

Google Adwords allows its clients to choose the keywords that relate to their business, and offers cost estimates as well as keyword traffic to allow its clients to make more-informed decisions on selecting keywords to help maximize their budget.

Yahoo! Sponsored Search also comes with an interesting, but much less powerful keyword-help feature, where various keywords (relevant to your business) will be displayed for advertisers to select from.

ADs Matching
Google Adwords uses a technology called contextual targeting that automates the matching of ads to relevant web pages in the Google content network. Google Adwords also offers its advertisers greater control by allowing them to hand-pick particular sections of websites where they wish to see their ads appear.

Using Yahoo! Sponsored Search, the maximum cost-per-click and the quality of your ad determines where the ad will be displayed in the search results.

Reporting
Google Adwords advertisers can measure results using the placement performance report, through which an ad's performance can be reviewed site-by-site, to determine better-performing websites that should be targeted more aggressively.

Yahoo! Sponsored Search data are only updated daily.

What are the most popular Web analytics tools?

Google Analytics (www.google.com/analytics/) is in a class by itself. It offers substantially more functionality than the other basic tools, but is free.

Unlike tools such as Webalyzer or AWStats, you need to install Google Analytics on your site, which involves pasting a chuck of HTML (provided by Google) into every page. This obviously requires a bit of HTML know-how, but if you know what you're doing, shouldn't require too much effort. Depending on the size of your site and how it's set up, installing the Google Analytics code might take anywhere from a couple of minutes to a few hours. Once the code is added, Google displays your statistics in a custom reporting interface that you can view online.

In addition to the reports offered by tools like Webalizer or AWStats, Google allows you to find out how often visitors come to your site, tracks visitor conversion across a series of pages, compares the behavior of different types of visitors (such as new versus returning, or those from different referring sites), and much more. A selectable date range allows you to analyze any given time period, instead of being limited to a monthly view (as you are with AWStats and Webalizer). Google has a nifty feature that allows you to look at a rendered version of the site and see the percentage of people that clicked each link on a given page.

What kind of assistive devices are there?

Braille embossers transfer computer generated text into embossed Braille output. Braille translation programs convert text scanned-in or generated via standard word processing programs into Braille, which can be printed on the embosser.

Light signaler alerts monitor computer sounds and alert the computer user with light signals. This is useful when a computer user can not hear computer sounds or is not directly in front of the computer screen. As an example, a light can flash alerting the user when a new e-mail message has arrived or a computer command has completed.

Screen readers are used to verbalize, or "speak," everything on the screen including text, graphics, control buttons, and menus into a computerized voice that is spoken aloud. In essence, a screen reader transforms a graphic user interface (GUI) into an audio interface. Screen readers are essential for computer users who are blind.

Speech recognition or voice recognition programs, allow people to give commands and enter data using their voices rather than a mouse or keyboard. Voice recognition systems use a microphone attached to the computer, which can be used to create text documents such as letters or e-mail messages, browse the Internet, and navigate among applications and menus by voice.

Screen enlargers, or screen magnifiers, work like a magnifying glass for the computer by enlarging a portion of the screen which can increase legibility and make it easier to see items on the computer. Some screen enlargers allow a person to zoom in and out on a particular area of the screen.

Other benefits to using Web standards

(1)Reducing dependency on any one developer
A common challenge for web developers when assuming management of existing sites is the code written by other developers with poor HTML code quality. Because standards are very well documented, another person taking over some standard-compliant code can hit the ground running - and will not need to become familiar with the previous developer's coding practices.

(2)Benefits to web site visitors
Thanks to accessibility, faster loading web pages, and compatibility with more browsers, visitors are more likely to appreciate your service and come back later.

(3)Increase Website Traffic -Better search engine ranking
Separating presentation from content increases the information/markup ratio, making CSS-based documents more pertinent with regard to the search terms, which makes them rank higher in search results.

(4)Compatible with newer browsers
More and more browsers, other than Internet Explorer for Windows, are used to surf the web. However, testing each web page in every configuration is impossible. Coding to standards is then the only practical solution.
