Web 2.0 is generally seen as an interactive social web that facilitates collaboration between people.
On the other hand, Web 3.0 is sometimes referred to as the Web of Everything because it is basically available anywhere at any time.
When it comes to Web 2.0, think of sites that consist of user opinions that give us insight on particular products. For example, customers leaving reviews for purchases or services. This can lead to false or misleading information. Users may give dishonest information due to personal feelings or beliefs.
When it comes to Web 3.0, think more of Artificial Intelligence (AI) that can learn how to analyze data and give us more reliable results.

You have probably heard the term "web 3.0" floating around the internet. Simply put, web 3.0 is the new phase of the internet's evolution. The changes that web 3.0 is bringing to the internet is going to take it to a whole new level. Computer scientists and Internet experts believe that these changes are going to make the internet smarter and our lives easier. So, to understand these paradigm-shifting changes, let's first look at the evolution of the internet as we know it.

Web 1.0 -> Web 2.0 -> Web 3.0: The Evolution

As we are going to see soon, the internet has evolved along with our needs and uses.

Web 1.0

Believe it or not, there used to be a version of the internet that existed before social media and video streaming! This was a time before Google in the mid-to-late '90s. The internet used to be dominated by AltaVista and Netscape. Back then the internet existed to only advertise their brick-and-mortar companies. These websites were "read-only web," meaning you were only allowed to search for information and read it.

Most e-commerce websites are still web 1.0 in nature since the concept behind them is simple. Present products to the customers and take money from the ones who are interested. These websites are usually very smooth and fast, however, the level of user interaction is minimalistic.

Web 2.0

The next iteration of the internet was called the "web 2.0" or the "read-write" web. Now, users were not just idle visitors, they could create their own content and upload it to a website. Starting roughly around 2003 when the term was coined by Dale Dougherty, Vice President at O'Reilly Media, web 2.0 has taken over the world by storm. In just over a decade, it has completely redefined marketing and business operations.

Instagram Influencers can make or break a brand by posting one single photo, Yelp reviewers can destroy a restaurant by one single negative review. Audience reviews are critical when it comes to buying decisions. According to a survey, 90 percent of customers reading online reviews before purchasing and 88 percent of them trusting them as much as a personal recommendation.

Web 2.0's main aim was to make the internet more democratic and make it as user-accessible as possible.

Web 3.0

Chances are that you are pretty familiar with the concept of web 3.0 already. Does this seem familiar to you?

Every time you buy something on Amazon, the website's algorithm will look at the other items that people who have purchased your product went on buy and then recommends that to you. So, think about what is going on here. The website is learning from other users what your preferred choices can be and then use it to recommend to you what you may like. In essence, the website itself is learning and becoming more intelligent.

That, in a nutshell, is the very philosophy behind web 3.0. Web 1.0 was primarily driven by content that came from the business or the institution for its customers. Web 2.0 took things a little bit further by allowing users to upload and share their content on the website itself. Web 3.0 allows online applications and websites to receive information that's on the Web and give new information/data to the users.

As Gian Gonzaga, Ph.D., senior director of research and development at the dating site eHarmony, says, "The Web can give something back that was not previously known. Web 3.0 learns and understands who you are and gives you something back."

The 4 Properties of Web 3.0

To understand the nuances and subtleties of Web 3.0, let's look at the four properties of Web 3.0:

Property #1: Semantic Web

One of the key elements of Web 3.0 is "semantic web." Tim Berners-Lee coined the term for a web of data that can be processed by machines. Berners-Lee originally expressed his vision of the Semantic Web as follows:

"I have a dream for the Web [in which computers] become capable of analyzing all the data on the Web - the content, links, and transactions between people and computers. A "Semantic Web", which makes this possible, has yet to emerge, but when it does, the day-to-day mechanisms of trade, bureaucracy, and our daily lives will be handled by machines talking to machines. The "intelligent agents" people have touted for ages will finally materialize."

Ok, so what does that mean in simple language? What does semantics really mean?

What is the difference between "I love Bitcoin " and "I <3 Bitcoin"?

The syntax between the two sentences is different but the semantics between the two is identical. Semantics deals with the meaning or the emotion conveyed by the data, and in our case, both of those sentences express the same sentiment.

Semantic web along with artificial intelligence are the two cornerstones of web 3.0. The semantic web will help teach the computer what the data means and that will evolve artificial intelligence that can utilize that information. The core idea is to create a spiderweb of knowledge across the internet which will help it to understand the meaning of words to generate, share, and connect content through search and analysis.

Thanks to semantic metadata, Web 3.0 will help in greater connectivity between data. As a result, the user experience evolves to another level of connectivity that leverages all the available information.

Property #2: Artificial Intelligence

Up next we have artificial intelligence. Currently, along with the blockchain technology, AI is the hottest and the most disruptive tech out there. According to Wikipedia, "In the field of computer science, artificial intelligence, sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and other animals." As such, artificial intelligence will help machines become more intelligent to satisfy the needs of users.

AI will allow websites to filter and present users the best data possible. Currently in web 2.0, we have started taking user opinions to help us understand the quality of a particular product/asset. Think of a website like Rotten Tomatoes where users get to vote on a list of movies. Movies with a higher rating are usually considered "good movies". Lists like these help us get to the "good data" without going through "bad data."

Peer reviews, as we have already mentioned, is one of the biggest contributions of Web 2.0. However, as we know, human recommendations are not incorruptible. A group of people may get together and give positive ratings to an undeserving movie, boosting their ratings up. Artificial intelligence can learn how to separate the good from the bad and gives us reliable data.

Property #3: 3D Graphics

Web 3.0 is going to change the future of the internet develops from the simple 2D web into a more realistic three-dimensional cyberworld. The three-dimensional design is being used extensively in websites and services in Web 3.0 such as online games, e-commerce, real-estate industry etc.

As alien as this concept sounds, the fact remains that there are thousands of people around this world who are already interacting in this space. Think about online games like Second Life or World of Warcraft where users are far more interested in the well-being of their online avatars than their real-world selves.

Philip Rosedale, the founder of Second Life, believes that virtual identities will become as popular as email addresses and mobile phones. This may seem far-fetched but remember that just 20 years ago in 1997, only a handful of people owned their email addresses. There is every chance that the amount of people with 3D identities is going to be on the rise.

Property #4: Ubiquitous

Ubiquitous means the idea of existing or being everywhere, especially at the same time i.e., omnipresent. We have already got this feature in Web 2.0. Think of social media websites like Instagram, users capture images on the camera and they can upload and distribute it online where they become their intellectual property. The image thus becomes accessible everywhere aka ubiquitous.

Development of mobile devices and internet access will make the web 3.0 experience available anywhere at any time. The internet will no longer only be on your desktop like with Web 1.0, or your smartphone, like Web 2.0. It will be omnipotent. Web 3.0 may as well be called the web of everything and everywhere, as most things around you are connected online aka Internet of Things.

We are slowly reaching this level, but we are steadily getting there.

Challenges of Web 3.0 Implementation

Let's look at some of the biggest challenges of Web 3.0 implementation:

Advantages and Disadvantages of Web 3.0

The Advantages of the Web 3.0:

Vastness: The internet is HUGE. It contains billions of page and the SNOMED CT medical terminology ontology alone includes 370,000 class names, and existing technology has not yet been able to eliminate all semantically duplicated terms. Any reasoning system which can read all this data and understand its functionality will have to be able to deal with vast amounts of data.

Vagueness: User queries are not really specific and can be extremely vague at the best of times. Fuzzy logic is used to deal with vagueness.

Uncertainty: The internet deals with scores of uncertain values. For example, a patient might present a set of symptoms that correspond to many different distinct diagnoses each with a different probability. Probabilistic reasoning techniques are generally employed to address uncertainty.

Inconsistency: Inconsistent data can lead to logical contradiction and unpredictive analysis.

Deceit: While AI can help in filtering data, what if all the data provided is intentionally wrong and misleading. Cryptography techniques are currently utilized to stop this problem.

The Disadvantages of Web 3.0:

So, there you have it. We are on the verge of a real internet revolution. While it is true that there are several challenges to Web 3.0 implementation, the sheer innovation that it can bring to our lives is truly mind-boggling. While there is a lot of hype, we still need some practical use-cases of Web 3.0 to truly understand the positive changes it can bring to our lives.

Increased information linking: Semantic web will help in the connectivity of online data.

Efficient searching

Better marketing.

More efficient web browsing.

Effective communication.

Change human interaction.

Less advanced devices will not be able to handle Web 3.0.

Web 1.0 websites will seem that much more obsolete

It can be very complicated for newcomers to understand.

Web 3.0 is the new phase of the Internet's evolution. Experts believe that the changes Web 3.0 are bringing to the Internet will make the Internet smarter and our lives easier. Web 3.0 allows websites and online apps to receive information on the web and give new data to the users. Semantic web and artificial intelligence are seen as cornerstones of Web 3.0. The Semantic Web is a web of data that can be processed by machines. It helps teach the computer what the data means and will in turn allow for more informed decisions made by the computer. The user experience evolves to a new level of connectivity. Almost everything around us is connected online.

# data[].attributes.attachment_link.readable_text
Web 2.0 are websites and applications that make use of user-generated content for end-users. Web 2.0 is characterized by greater user interactivity and collaboration, more pervasive network connectivity and enhanced communication channels.

One of the most significant differences between Web 2.0 and the traditional World Wide Web (, retroactively referred to as Web 1.0) is greater collaboration among Internet users, content providers and enterprises. Originally, data was posted on Web sites, and users simply viewed or downloaded the content. Increasingly, users have more input into the nature and scope of Web content and in some cases exert real-time control over it.

The social nature of Web 2.0 is another major difference between it and the original, static Web. Increasingly, websites enable community-based input, interaction, content-sharing and collaboration. Types of social media sites and applications include microblogging, social networking, Social bookmarking, social curation, and .
Elements of Web 2.0

Wikis: Websites that enable users to contribute, collaborate and edit site content. is one of the oldest and best-known wiki-based sites.

The increasing prevalence of Software as a Service (), and cloud computing rather than locally-installed programs and services.

Mobile computing, also known as nomadicity, the trend toward users connecting from wherever they may be. That trend is enabled by the proliferation of smartphones, tablets and other mobile devices in conjunction with readily accessible Wi-Fi networks.

Mash-ups: Web pages or applications that integrate complementary elements from two or more sources.

Social networking: The practice of expanding the number of one's business and/or social contacts by making connections through individuals. Social networking sites include , , and .

Collaborative efforts based on the ability to reach large numbers of participants and their collective resources, such as crowdsourcing, crowdfunding and crowdsource testing.

User-generated content (): Writing, images, audio and video content -- among other possibilities -- made freely available online by the individuals who create it.

Unified communications (): The integration of multiple forms of call and multimedia/cross-media message-management functions controlled by an individual user for both business and social purposes.

Social curation: The collaborative sharing of content organized around one or more particular themes or topics. Social content curation sites include , and .

The History of Web 2.0
The foundational components of Web 2.0 are the advances enabled by and other applications such as RSS and and the user empowerment that they support.

Darcy DiNucci, an information architecture consultant, coined the term "Web 2.0 In her 1999 article, "Fragmented Future":
"The Web we know now, which loads into a browser window in essentially static screenfuls, is only an embryo of the Web to come. The first glimmerings of Web 2.0 are beginning to appear, and we are just starting to see how that embryo might develop. The Web will be understood not as screenfuls of text and graphics but as a transport mechanism, the ether through which interactivity happens."
Tim O'Reilly is generally credited with popularizing the term, following a conference dealing with next-generation Web concepts and issues held by O'Reilly Media and MediaLive International in 2004. O'Reilly Media has subsequently been energetic about trying to copyright "Web 2.0" and holds an annual conference of the same name.

Web 2.0 controversy
Critics of Web 2.0 maintain that it makes it too easy for the average person to affect online content, which can impact the credibility, ethics and even legality of web content. The extent of data sharing and gathering also raises concerns about privacy and security. Defenders of Web 2.0 point out that these problems have existed ever since the infancy of the medium and that the alternative -- widespread censorship based on ill-defined elitism -- would be far worse. The final judgment concerning any web content, say the defenders, should be made by end users alone. Web 2.0 reflects evolution in that direction.

Web 2.0 technologies
Most of the technologies used in delivering web 2.0 are rich Web technologies, such as Adobe Flash, Microsoft Silverlight and JavaScript (in addition to Ajax, RSS and Eclipse). Web 2.0 applications are often based on the decentralized download methodology that made BitTorrent so successful, in which each downloader of content is also a server, sharing the workload and making heavily demanded content more accessible that it would be in the centralized model where demand can lead to overwhelmed servers and pages.

Manufacturing 2.0
The integration of Web 2.0 communication and collaboration applications into traditional manufacturing practices and processes has been dubbed Manufacturing 2.0. Manufacturing 2.0 takes typical Web 2.0 apps and services and incorporates them into every stage of development and production. The use of these technologies and tools facilitates greater collaboration and sharing and referencing of information in a business, ideally leading to better thought out design and more efficient production.

Enterprise 2.0
Similarly, the inclusion of Web 2.0 technologies into an enterprise's business processes, Intranet and is sometimes referred to as Enterprise 2.0. Most enterprise 2.0 followers use a combination of blogs, social networking and social collaborative tools as well as free, paid and homegrown technologies. The term Enterprise 2.0 was coined by Harvard Business School Associate Professor Andrew McAfee in an MIT Sloan Management Review he named "Enterprise 2.0: The Dawn of Emergent Collaboration."

Web 2.0 suicide
So synonymous with Web 2.0 is social networking that the deletion of one's social networking presences throughout the Internet is referred to as Web 2.0 suicide. There are web applications designed to facilitate the process, such as the free service Web 2.0 suicide machine. The application attempts to purge user info on some of the most common social networking presence points: Facebook, MySpace, LinkedIn and Twitter before adding the user to the Social Network Suiciders group on Facebook and signing them out.

The future of Web 2:0: Web 3.0
Some industry pundits are already claiming that Web 2.0 is merely a transitional phase between the early days of the World Wide Web's existence and a more established phase they're calling Web 3.0.

The creator of the World Wide Web, Tim Berners-Lee, suggests that the Web as a whole can be designed more intelligently to be more intuitive about how to serve a user's needs. Berners-Lee observes that although search engines index much of the Web's content, they have little ability to select the pages that a user really wants or needs. He suggests developers and authors, singly or in collaboration, can use self-descriptions or similar techniques so that new context-aware programs can better classify the information that might be relevant to a user.

Ubiquitous Computing
The model of Web 3.0's machine-classified, data sharing world creates a basis for ubiquitous computing. Ubiquitous computing, also known as pervasive computing, is a scenario in which embedded processing in everyday objects enables intercommunication and unobtrusive data sharing throughout the user's environment. The concept overlaps with that of the Internet of Things ( IoT), in which almost any entity or object imaginable can be outfitted with a unique identifier (UID) and the ability to exchange data automatically. A modest example of this concept is a fridge that sends a grocery lists to one's smartphone.

Examples
* Social Media sites/apps such as Twitter and Remind Messaging can be used in educational settings as a means for educators and students to keep in contact with each other. Students can collaborate from any location as long as they have Internet connection. Educators can send assignments, due dates and resources easily. These sites can also be used as discussion forums on specific topics.
* Blog sites such as Wordpress and EduBlogs can be an outlet for both educators and students. It is a way to express ideas and thoughts, share research, and even pose questions for others to answer. Blog authors can allow other users to comment on posts creating a space for discussion.
* Wikis are collaborative software that allow users to add content that can in turn be edited by anyone. They can be used to search for or share knowledge.

Web 1.0 is the term used to refer to the first stage of development on the World Wide Web that was characterized by simple static websites.
The term Web 1.0 didn't appear until the term Web 2.0 was coined in 1999 by Darci DiNucci. During that time, the web was undergoing a major transformation. Most websites in the 1990s had originally been built with static HTML pages, and a few simple styles embedded in the HTML markup. In the late 1990s and early 2000s, interactive website features redefined what could be accomplished in a web browser and marked a major point of evolution in the world of web development.

During the stage known as Web 1.0, websites were marked by the following typical Web 1.0 characteristics:

Static pages: Pages didn't offer interactive features that changed based on website visitor behavior. At that point websites were largely informational.

Website content stored in files: Virtually every modern website makes use of a database to store the majority of website content. During Web 1.0 this was not the case and most website content was stored directly in the website files, not in a separate database.

Combination of content and layout: Good web design practice today dictates the separation of webpage markup and styling. Virtually every modern website makes use of external style sheets to determine the look and layout of webpages. During Web 1.0 most styling was built into the page markup itself, often by misusing HTML elements such as tables.

Proprietary HTML tags: During Web 1.0 browsers attempted to stand out by offering support for proprietary tags, creating significant incompatibility problems between websites that used these tags and site visitors using unsuported browsers.

Guestbooks: Website visitor comments were usually added to a Guestbook page rather than attached directly to content pages.

E-mailing of forms: Web hosting servers during the Web 1.0 phase rarely offered support for server-side scripting, which is required to use the web server to submit a form. As a result, during Web 1.0, when the Submit button was clicked on most forms the website visitor's e-mail client would launch, and the visitor would have to e-mail their form to an e-mail address provided by the website.

The transition from Web 1.0 to 2.0 took place over time as servers were upgraded, average connection speeds increased, and developers learned new skills and techniques. The transition began in the last year or two of the 1990s and Web 2.0 features had made strong headway by 2006, although there are still vestiges of Web 1.0 with us today in quiet corners of the web.

Frequently Asked Questions

What marked the transition to Web 2.0?

There are a number of factors that marked a departure from Web 1.0 to 2.0 such as user-generated content in the form of comments, the use of databases to store content, growth in the ability of web servers to process server-side scripting languages, and the birth and explosion in growth of social media. To learn more, visit the Web 2.0 entry in our Interactive Glossary.

Why were Guestbooks a popular feature during Web 1.0?

Web 1.0 coincided with a time when dial-up Internet connections were common. Pages with long lists of user comments would take a long time to load over a dial-up connection. A Guestbook was a solution to the desire to allow user comments without bogging down the overall performance of a website. In this way, user comments were allowed, but wouldn't slow down performance of content pages.

Was blogging popular during Web 1.0?

While personal websites were popular, and there were a few sites that could be characterized as blogs by today's standards, blogging was not popular or accessible to the average web user during Web 1.0. Blogging depends on in-browser text editing, databases, server-side scripting, and other Web 2.0 features. During Web 1.0, regular website updates required a lot more technical skill than what is required today to run a blog.

Web 1.0 refers to the first stage of development of the World Wide Web. The term 'Web 1.0' did not exist until the term 'Web 2.0' was coined in 1999 by Darci DiNucci.

Typical Characteristics
* Pages were static. This means they did not have interactive features that could be modified by users. Sites were generally informational.
* Most website content was stored directly in the website files, as opposed to a separate database.
* Website visitor comments were typically added to a Guestbook page rather than attached directly to the content page.
* When users went to submit a form, their email would launch and they would have to submit to an email address provided by the website.
