What is Web 2.0 and Web 3.0?
Web 2.0 is a term that describes the second generation of the World Wide Web technology and Web design. It focuses on the ability to enhance creativity, share information online, increase collaboration and improve the Web functionality from Web 1.0. Web 2.0 is flexible, simple and lightweight, in which it is easy to use, adopt, create and deliver. This has therefore led to the development of online communities and hosted services such as social-networking sites, blogs, and wikis (as discussed in the first blog post). This has shifted the development of the Web from a passive consumption of content to an active role where participation, creation and sharing are involved. These sites have an “architecture of participation” which encourages users of application to add value from their involvement, in comparison to Web 1.0 which only allows visitors to passively view the website content only the owners can modify. What attracts users to the Web 2.0 developments is that it provides the ease of communication, coordination, online self-expression and the ability to control their educational learning and create customised information, resources, tools and services.
Web 3.0 is the next step in the evolution of the Internet and Web applications based on how websites are created and, more importantly, how people interact with them. The CEO of Google Eric Schmidt defines it as small data from applications that can run on any device, in a fast, customizable and virally distributed way through social media. These applications allow users to generate content that is personalised and managed more efficiently through multiple information coming from apps that are intelligent enough to do the searching of the user’s histories and interests. A benefit of Web 3.0 is the ability to access data from anywhere which has driven the usage of smart phones can cloud apps. Key emerging technology trends include broadband adoption, mobile internet access and mobile devices. A common example of using Web 3.0 is if you want to watch a movie and get food afterwards, you could type in a complex sentence like “I want to watch a latest movie and then get pizza afterward, what are my options?” The Web 3.0 browser with then analyse your question and search the internet for potential answers and show all the possible results.
Information Architecture
Information Architecture (IA) is the art and science of organizing and labelling websites, intranets, online communities and software to support usability. The IA process is the first thing you do when designing a site. It determines what, how and where information will be stored, processed, collected and used as well as how the content of the website is organised and presented to people with the use of navigation and search functions. In other terms, it is figuring out what you want your site to do and then constructing a blueprint with the creation of site maps, hierarchies, categorizations, navigation, and metadata. It is essential to first define the goals and reason for the site, determine the target audience, the content of the site, metaphor exploration and the layout grid for the site. Design elements for the site include: navigation, colours, context and accessibility, mobile sites, syndication, and succinct writing. Further information on IA can be found on WebMonkey.
Relationship of information Architecture to Web 2.0 and 3.0
Web 2.0 and 3.0 has a direct impact on what we do with Information Architecture. It is based the usability, findability and Extensibility.
- A navigation model based on social goals, where we want content created, and becomes a framework for users to build on.
- A content model based on what users need to create and share, what other users look for, which supports user content.
- A metadata model that captures social dimensions, what’s important to users and supports social interaction

Information architect sets up initial structure for the site, users pages and content and handles the ongoing review of site design, placement of problem topics (under the Navigation model). Overall they controls the design and categories of the website.
Semantic Web: The Semantic Web is an extension of the current Web which allows people to share, reuse, and combine information across application, enterprise and community boundaries. It is based on machine-readable information and XML technology, making it possible for the web to understand and satisfy the requests of people and machines on the web content (provides a common language). For example, a computer program can learn enough about the data in order to process it without any human input. In other words, it teaches the computer to do the reading.
Internet of Things: This refers to the network of physical objects that feature an IP address for internet connectivity, as well as the communication between objects and other internet-enabled devices and systems. After connecting the device over the internet, it might talk to us, communication with the apps or with each other. For example, it is used in some home heating where there are clever function that automatically turn down the temperature if it is sunny or even turn off when there is no one home.
Artificial Intelligence (AI): This is the intelligence exhibited by machines. It is a branch of computer science related with making computers behave and understand human intelligence. Currently no computers are able to fully exhibit human behaviour. However, the greatest advances have come from games such as computer chess which has the ability to beating human opponents. Other than games, AI includes specializations such as expert systems, natural language, neural networks and robotics.
Theres also Web 4.0 AND Web 5.0! What does the future hold?
Although both Web 4.0 and Web 5.0 are still in the developing mode, we do know that it will be about a linked web which communicates with us like we communicate with each other. This is called a “symbiotic” web.
Web 4.0 can be considered as an Ultra-Intelligent Electronic Agent, symbiotic web and Ubiquitous web. This is where machines would be able to read the content of the web and react with speed, superior quality and performance and with more commanding interfaces. It will be able to read and write concurrency web. According to Choudhury (2014), Web 4.0 will be able to start functioning like an operating system with similarities to the human brain as a massive web of highly intelligent interactions.
When it comes to Web 5.0, it is presumed to be about the emotional interaction between humans can computers based on neuro-technology. With an emotional web this will enable and recognise how users feel. An example of this is http://www.wefeelfine.org, which maps emotions of people. By using headphones, users can interact with the content which further interacts with their feels or facial recognition

Question Time!
What do you like about Web 2.0 and 3.0?
What Artificial Intelligence have you experienced (maybe from a game you played)?
In terms of the Internet of Things, have you come accross any physical objects in your household, school, work?
