Webmastering: Semantic Web

Wikipedia.org Definition: The Semantic Web is an evolving development of the World Wide Web in which the semantics of information and services on the web is defined, making it possible for the web to understand and satisfy the requests of people and machines to use the web content.
SemanticWeb.org wiki definition: The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites. It has been described in rather different ways: as a utopic vision, as a web of data, or merely as a natural paradigm shift in our daily use of the Web. Most of all, the Semantic Web has inspired and engaged many people to create innovative semantic technologies and applications. semanticweb.org is the common platform for this community.

Semantic web is one of the Web3.0 technologies.

Semantic Vs. Syntax?

Syntax in linguistics: is the study of the principles and rules for constructing sentences in natural languages.

Semantic: is the study of meaning.

How Semantic Web (SW) works?

Although the computers present the data (texts, imges & videos) from any given website well, yet computers doesn't understand the content of the website sent data.

Semnatic web aims to give a computer valid meaning for the data sent through any given website, through applying metadata to any given site, to make these data readable by computers.

Such process will help much the quality of search results dramatically.

The process is simple, suppose that you have a blog where you post essays about technology and gadgets, with different images, videos.

Now you want to improve your rank through search results for semantic web search engines, you are going to mark up your videos with metadata, it is easier for semantic search engines to relate, find and exchange information about the content posted.

Webmastering: Beyond Web 3.0

Experts of the Web, seem to have no limit for their expectations about the Web.

Next is a part of "Howstuffworks.com: Beyond Web 3.0"

Some Experts opinions About the Web:

• According to technology expert and entrepreneur Nova Spivack, the development of the Web moves in 10-year cycles. In the Web's first decade, most of the development focused on the back end, or infrastructure, of the Web. Programmers created the protocols and code languages we use to make Web pages. In the second decade, focus shifted to the front end and the era of Web 2.0 began. Now people use Web pages as platforms for other applications. They also create mashups and experiment with ways to make Web experiences more interactive. We're at the end of the Web 2.0 cycle now. The next cycle will be Web 3.0, and the focus will shift back to the back end. Programmers will refine the Internet's infrastructure to support the advanced capabilities of Web 3.0 browsers. Once that phase ends, we'll enter the era of Web 4.0. Focus will return to the front end, and we'll see thousands of new programs that use Web 3.0 as a foundation [source: Nova Spivack].

• The Web will evolve into a three-dimensional environment. Rather than a Web 3.0, we'll see a Web 3D. Combining virtual reality elements with the persistent online worlds of massively multiplayer online roleplaying games (MMORPGs), the Web could become a digital landscape that incorporates the illusion of depth. You'd navigate the Web either from a first-person perspective or through a digital representation of yourself called an avatar.
  

• The Web will build on developments in distributed computing and lead to true artificial intelligence. In distributed computing, several computers tackle a large processing job. Each computer handles a small part of the overall task. Some people believe the Web will be able to think by distributing the workload across thousands of computers and referencing deep ontologies. The Web will become a giant brain capable of analyzing data and extrapolating new ideas based off of that information.

• The Web will extend far beyond computers and cell phones. Everything from watches to television sets to clothing will connect to the Internet. Users will have a constant connection to the Web, and vice versa. Each user's software agent will learn more about its respective user by electronically observing his or her activities. This might lead to debates about the balance between individual privacy and the benefit of having a personalized Web browsing experience.

• The Web will merge with other forms of entertainment until all distinctions between the forms of media are lost. Radio programs, television shows and feature films will rely on the Web as a delivery system.

it's too early to tell which (if any) of these future versions of the Web will come true. It may be that the real future of the Web is even more extravagant than the most extreme predictions. We can only hope that by the time the future of the Web gets here, we can all agree on what to call it.

As per my comment the Web is still under discovering it's real potential.

Webmastering: Web 1.0, Web 2.0, Web 3.0

Web 2.0: is a terminology coined by Dale Dougherty of O'Reilly Media,to simply notify the tremendous changes in the web as a media.

Web 2.0 Refers to the use of the same technologies yet in different techniques for the site development and execution to allow better user experience through easy sharing, bloging , RSS service, social networking.

web 2.0 refers to websites that:

• Give the ability to users to add and change the content of the website (that belongs to Web 2.0 website) such as Amazon.com, Forums.
• Give the ability to people tio link to each others in a huge social networks, such as Facebook.com, MySpace.
• Give the ability to visitors to easily share content, such as YouTube.com.
• Extend the use of the internet to other devices than Personal computer and laptops, many people now extend the use of internet to cellular phones, gaming concoles and in the near future television sets will join the horde or face teh extinction, just like the late VCR.
• Also, allowing the users to grab a quick news alerts using RSS (Really Simple Syndicate), wihtout going through a dozen of web sites to get this mission accomplished.

Web 2.0 is intended to be:

1. The internet is an applications platform (cloud Computing).
2. Democratizing the web (allowing more people to share and add and change data in the Web 2.0 websites).
3. Employ more mehtods of information discloser (open information range).

Q: What is Web 1.0?

A: that is a simple question to ask, yet controversal to answer.

Web 1.0: is -as a casual not professional answer- whatever website that doesn't provide any of the Web2.0 services.

Let's think of Web 1.0 as a library, you can useit a source of information but you can't share the onformation nor you can contribute to this library.

in the library example Web 2.0 is a group of friends, while you can recieve information you can share and contribute information within this group of friends.

Web 1.0 Refers to websites that:

1. aren't Interactive: might contain useful data, but not continiuosly changing and growing data.
2. are Static, Visitors of these websites aren't able to Add or Change any part of the data.
3. aren't open source, Web 1.0 depends on proprietary software that is owned by companies and not allowable by public to alter or add any code snippets to it, on contrary is the open source software where poeple, publicly, own the software and its code is opened to be altered or added to.

Q: What is Web 3.0?

Web 3.0 is -in short- personalizing the web to the visitors, it is the upcoming revolution in the web techniques.

Many experts believe that the Web 3.0 browser will act like a personal assistant. As you search the Web, the browser learns what you are interested in. The more you use the Web, the more your browser learns about you and the less specific you'll need to be with your questions.

As I write this blog entry, I know that Google uses Google Account to personalize search results for registered visitors.

Many experts compare Web 3.0 to a giant database, which will use the Internet to make connections with information.

A Web 3.0 search engine could find not only the keywords in your search, but also interpret the context of your request. It would return relevant results and suggest other content related to your search terms.

Experts believe that:

• Web 3.0 will provide users with richer and more relevant experiences.
• with Web 3.0, every user will have a unique Internet profile based on that user's browsing history.
• the foundation for Web 3.0 will be application programming interfaces (APIs). An API is an interface designed to allow developers to create applications that take advantage of a certain set of resources.
• Web 3.0 will start fresh. Instead of using HTML as the basic coding language, it will rely on some new -- and unnamed -- language. These experts suggest it might be easier to start from scratch rather than try to change the current Web.

Experts beliefs are more applicable and going into actual steps.

I hope to see more virtual reality to the Web 4.0
