2nd ViPi Workshop; 02/05/2012, Vilnius, Lithuania
SCENE #1 – AT THE BOOKSTORE IN 1999
Gabrielė enters the bookstore where Ignacijus (the owner) is sitting on his desk reading
“Hi Ignacijus! How are you doing today?” “Good morning Gabrielė. Everything is Fine..how can I help you? Are you looking for something specific?” “Well, I want to read and learn how to use MS
Word..I need it for my job”

SCENE #1 – CONTINUE
“Ok, Gabrielė…looking at the shelves here, I suggest you take these two books…”
the first is clear from the title that is about MS Word, the second not that clear but should be fine as the first gives reference to it in the text” “Thank you Ignacijus! Let me check a little bit their content”

“Ignacijus…it seems that the second book has nothing to do with MS Word!”
“I am sorry Gabrielė for the inconvenience…was not able to know…I will try to remember it”
MS Word is a text processing tool that…
Internet Explorer is not a text processing tool, like MS Word is.
Internet Explorer is a web browser…

SCENE #2 – AT THE BOOKSTORE IN 2004
6
As time passed, many more writers were sending books to Ignacijus store…from journals to comics to scientific articles to cooking recipes to academic books…
Ignacijus was standing sad, as he could not be of any help to his customers anymore…too much information to process

SCENE #3 – AT THE BOOKSTORE IN 2008
Ignacijus was in the process of organising his store…he bought a computer and also a furniture for storing card-catalogs
Then he tagged all books with card-triplets of the form [subject – property – object]
and properly filed this tagging…he was now able to look at the cards and locate any book to match his customers’ needs
2nd ViPi Workshop; 02/05/2012, Vilnius, Lithuania
SCENE #3 – CONTINUE
For convenience Ignacijus used the following tagging for the books: [bookID1 - is about - MS Word] [MS Word - is a tool for - text processing] [Libre office - has tools for - text processing] [bookID2 - is about - Web browsers] [Internet Explorer - is a - Web browser] … [Gabriele – speaks – Lithuanian] [Gabriele – prefers to pay by – credit card] [Silvijus – has impairment – visual] [Silvius – uses assistive device – keyboard] 8

SCENE #4 – AT THE BOOKSTORE IN 2012
Silvijus enters the bookstore and asks for a book about ViPi mobile applications
“Hi Silvijus…yes of course I can help you…let me check my computer and I will bring you exactly what you want!”
2nd ViPi Workshop; 02/05/2012, Vilnius, Lithuania
SCENE #4 – AT THE BOOKSTORE IN 2012
Ignacijus finds in his cards that Silvijus has a visual impairment, that he prefers to read books in English and that he is using some assistive technology with his keyboard…
So he goes directly on the proper shelf and brings two books that fit exactly what Silvijus needs and are also accessible for him

THE STORY OF THE WEB Initially the Web was full of static websites and
interlinked pages/documents. Nice!! People were searching using keywords and were
provided with lots of results through which they were (sometimes) able to find exactly what they wanted. Lately, the search engines also became smarter
and helped people by learning of links… But then social networking sites came, and blogs and
wikis and collaboration tools and… They allowed anyone to write and publish content
on the Internet The Web 2.0 era…Very nice!!! but
Too much information and too difficult to search within11

THE STORY OF THE WEB
And finally the Web 3.0 era started where ICT scientists realized that this huge repository of content should somehow be organized and tagged semantically. The Semantic Web! The content entities/objects
(text, images, videos, chats, emails, blog posts, etc) is not thrown in the repository directly, but is first described with pre-defined vocabularies
[Subject --Property -- Object]
Even better! 12
2nd ViPi Workshop; 02/05/2012, Vilnius, Lithuania
VIPI UTILIZES THE SEMANTIC WEB CONCEPTS
ViPi large repository of Learning Objects (LOs) All LOs are semantically tagged with
predefined vocabularies [LOid1 – is of type - video] [LOid1 – is compatible with impairment - hearing]
At the same time, all users’ profiles are enriched with semantic tags [User1 – has impairment - hearing] [User1 – prefers content of type –
image/video/text] Searching through the repository and finding
the proper content becomes much easier because of the stored meaning!
