Web 3.0: Semantic web Presentation by: Amardeep Singh Shakhon Introduce yourself! Introduction about what your covering in the presentation Presentation by: Amardeep Singh Shakhon
Mental image Abstraction Language This is the process most users use when looking at content or images on a webpage. 1) Initially they look at points of interest and create a mental image of the information. 2) Once the mental image is defined they abstract information from that image to define a recognisable language in their mind. This entire process is done within milliseconds! Users have a ‘subjective’ view to content e.g. Image “My daughter” – everyone in this room would have a different interpretation of who that is what she looks like, what she's wearing, her age, height, etc... What we are doing is conceptualising a word and giving it meaning. By understanding this process the content we provide online can be tailored to help with the development of a recognisable mental image across user groups. ----------------- So what are the problems where facing now? (NEXT SLIDE )
“ Imagination without terms are blind and terms without imaginations are empty. ” Emaneoway Cont Emaneoway = Psylosper If i had something in mind i could tell you even if your not able to see it. On the other hand – If I was to use a term you don't know you would have no image in mind. This quote shows the powerful relationship between the words we use and their interpretation or response from the listener or users. It is important to be clear when using words to help paint the ‘right’ picture in our users minds.
Current problem... Computers blindly retrieve and show us information The internet allows for computers to talk to one another but they were not designed to understand what the information actually means. Computers don’t understand what they are presenting. However if computers could understand the information they are showing they could change from passively helping us to actively helping us. That’s the problem!
What’s the difference? Semantic Web Current web People Places Rich media Possibly any concept you can think of. Separate data structures Relationships are defined by data clusters and/or business rules Hard to make data associations Semantic web The semantic web allows for information to have meaningful relationships between one another and also allows systems to communicate and learn from one another. EXAMPLE: If I was to book a dentist appointment online, and search for local dentists within a mile proximity from me. The system should return dentists who are within this range from me (nothing new). However it could go further and only present those dentists who have opening slot available that matches my availability e.g. from Outlook or my Gmail calendar. Current web is restricted to the architecture of a database structure and how information is sliced, not what it means. Therefore its not possible for systems to learn from each other at a semantic level. Web 2.0 has been designed for people to communicate with each other via online communication channels e.g. Facebook, LinkedIn. Whereas Web 3.0 is all about computers and systems communicating with each other.
How does it work? Scan multiple sites at the same time Ability to combine and relate content Create inference and reasoning Creation of information models The one of key interest to experience architects and practitioners would be ‘creation of information models’. NEXT SLIDE –>
Personal Information model (PIMO) Persons “Speaker name” Works for Calendar events Presentation Outlook Event hosted by an organisation Presentation chaired by: “Persons name” This personal information model show an example of possible connections that could occur in Web 3.0 applications. This is my personal information model at for me right now (the model is based around a presentation). Included in Organisation Organisation Organisation Bought to you by another organisation
How could we benefit from PIMO? Emailing systems Concept of ‘saving’ files (where do I put them?) Browsing information Here’s just three small examples of how personal information models can help users achieve their goals. EMAIL: An email system could make suggestion as to which topics emails belong to and automatically sort incoming information in a prioritised stake based on what your doing or deadlines. SAVING: The system could make valuable suggestions on where to save a document in relation to your pre-existing PIMO structure. By adding documents to this structure the system can grow, develop, learn and even rationalise reasons for saving things in certain ways. BROWSING INFOMRATION: PIMO would allow for an ‘Information push’ which is adaptive. Showing tasks, data sources, ‘concepts’ that are available. I going to discuss more on saving and browsing information in relevance to the personal information model. NEXT SLIDE
Saving to a PIMO? So lets suppose I wanted to save this presentation to my computer (say a hard drive) or to a web application e.g. Slideshare, Facebook or iGoogle. How would my personal information model help me to save this information?
Saving to a PIMO? This presentation Who What Where How Tarek Web 3.0 The PIMO allows the user to save new content semantically using words that help to describe and define content. Additionally this also allows the user to define the own taxonomy. This is an activity users already do e.g. Labelling folders on your desktop to help organisation data, activities. MULTI PERSPECTIVE ACCESS: This form of saving information allows users to access the same content from many angles. This is called ‘multiple perspective access’ which allows the data to be sliced in many ways whilst retaining its semantic structure and relationships. This combination of perspective directories means the user gets an excellent orientation of the data and multiple access points to his/her information space. (meaning: many more information retrieval and surfacing possibilities). Tarek Web 3.0 T-Mobile Talk
? Browsing information with PIMO Semantic tagging PIMO Users consider the contents of a web page or the document PIMO uses current web tagging services and then make proposals as to how to tag the information to best suit the users current PIMO.
Browsing information with PIMO Semantic Search Search enquiry text Internet PIMO User inputs a string search enquiry which is submitted along with the PIMO code (concepts and instances) The system would return information related to the string enquiry along with information relevant to the PIMO e.g. People, projects, concepts)

Google Docs! Watch the Video Google docs is a new free service that allows multiple users to work on a single file. This web application means users can access this information from anywhere in the world. It also allow for far great file integrity as file are not being copied and worked on separately. SHOW VIDEO https://www.google.com/accounts/ServiceLogin?service=writely&passive=true&nui=1&continue=http%3A%2F%2Fdocs.google.com%2F&followup=http%3A%2F%2Fdocs.google.com%2F<mpl=homepage&rm=false#
Wait this is online? Watch the Video As google docs is an online application it can bee access from any device. Your literately taking your office machine with you whilst maintaining contact with your colleagues.
gOS (Google Operating System) Watch the video Google are setting up for their release of the new google operating system. The GOS has been design around the internet and the idea of a ‘cloud’. The cloud is an online space allowing users to upload files and download them via multiple channel of communication. SHOW VIDEO http://www.youtube.com/watch?v=fIhfYKx8kCk
