Web 3.0 and Semantic 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: <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">Nova Spivack<span style="line-height:22px;font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">].

You can still use it to receive information but you also contribute to the conversation and make it a richer experience.

Characteristics of Web 2.0

 * <span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">The ability for visitors to make changes to Web pages: Amazon allows visitors to post product reviews. Using an online form, a visitor can add information to Amazon's pages that future visitors will be able to read.


 * <span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">Using Web pages to link people to other users: <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">social networking sites like Facebook and MySpace are popular in part because they make it easy for users to find each other and keep in touch.


 * <span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">Fast and efficient ways to share content: YouTube is the perfect example. A YouTube member can create a video and upload it to the site for others to watch in less than an hour.


 * <span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">New ways to get information: Today, Internet surfers can subscribe to a Web page's Really Simple Syndication (RSS) feeds and receive notifications of that Web page's updates as long as they maintain an Internet connection.


 * <span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">Expanding access to the Internet beyond the computer: Many people access the Internet through devices like cell phones or video game consoles; before long, some experts expect that consumers will access the Internet through television sets and other devices.

Current Problems with Web 2.0
<span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">1) <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">High recall and low precision<span style="line-height:22px;font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">. The most relevant pages are retrieved, but so are many other irrelevant or semi-relevant pages

<span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">2) <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">Low recall<span style="line-height:22px;font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">:  Sometimes we don’t get the answer we want at all

<span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">3) Results are too vocabulary-sensitive: Semantically similar words do not return similar results

<span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">4) Results return only single Web pages. We must travel to separate places, extract information, then bring together a solid body of information. This requires several queries

<span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">5) <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">Search engines<span style="line-height:22px;font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;"> are not integrated with software; they often stand isolated.

"Therefore the term <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">information retrieval<span style="line-height:22px;font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">, used in assocation with search engines[LINK], is somewhat midleading; location finder might be a more appropriate term." The <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">semantic meaning<span style="line-height:22px;font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;"> behind what information we with to retrieve is "not machine-accessible." The computer cannot interpret sentences the way humans can.

Rather than a <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">Web 3.0, we'll see a Web 3D. Combining virtual reality elements with the persistent online worlds of massively multiplayer online roleplaying games <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">(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 (to learn more about an avatar's perspective, read <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">How the Avatar machine Works).

<span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">​ <span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">The Web will build on developments in distributed computing and lead to true <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">artificial intelligence. In <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">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 <span style="font-size:15px;font-family:Arial;color:rgb(0,0,0);white-space:pre-wrap;">ontologies. The Web will become a giant brain capable of analyzing data and extrapolating new ideas based off of that information.

<span style="color:rgb(0,0,0);font-family:Arial;font-size:15px;white-space:pre-wrap;line-height:1.4em;">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.
