The Next Big Thing is Web 3.0: Catch it if you can! Judy O’Connell

What is Web 3.0?

Web 1.0 was for viewing and linking

Portable, personal web, focused on the individual, on lifestream, on consolidating content, and which is

powered by widgets, drag and drop, and mashups of user engagement.

Web 2.0 is about participation

• Personal learning environment – relying on the people we

connect with through social networks and collaborative tools e.g.

Twitter, Yammer.

• Personal learning network – learning content is not as important

as knowing where or to whom to connect and find content e.g.

Skype in the Classroom, iTunes U.

• Personal web tools – used for tracking our life and powering our

learning e.g. photos to Facebook, excursion pictures to Flickr.

• Cloud computing – supporting open access between sources

and devices rather than being locked to software and individual

computers. e.g. Edmodo, Evernote, Diigo.

• Mixed reality – encompassed by e-devices and augmented

reality e.g. ebooks, QRcodes, Layar browser.

This socially powered web is exploding, and is the new baseline for all our internet and technology empowered interactions.

Web 3.0 refers to a third generation of internet-based

services that collectively will allow the emergence of

the intelligent semantic web.

Semantic Web revolutionising knowledge discovery

Our Knowledge Encounters

The semantic web, or web 3.0, is all about data integration.

It is an infrastructure technology

and an organised approach to metadata.

New functionality that requires web linking, flexible

representation, and external access APIs.

You won’t see a “Web 3.0 inside’ label

The semantic web allows a person or a computer to start off

in one database, and then move

through an unending set of

databases which are connected, not

by wires, but by being about the

same thing.

Rather than just identifying keywords and expressions, the

semantic web concentrates on

identifying the meaning of content.

The goal of linked data is to enable computers to do more useful work for us by teaching machines to read web pages.

It is about common formats and

metadata which allow for integration and combination of

data drawn from diverse sources.

It is also about language, or ontology, for

recording how the linked data relates to real world objects, allowing a ‘machine’ to

‘understand’ the semantic meaning and the

difference between Jaguar (car) and jaguar

(animal).

Linked Data principles

1. Use URIs as names for things

2. Use HTTP URIs so that people can look up those names.

3. When someone looks up a URI, provide useful information using RDF standards

4. Include links to other URIs so they can discover more things

Semantic search

Web search engines have revolutionised the way people find and use information.

Yet Google can’t find everything, and it is important to understand limitations.

Put intelligence back into search

Rather than simply identifying a useful page, these systems try to pull the information from those pages

that might be what a user is looking for, and to make this immediately apparent.

A semantic search engine tries to help a user identify further searches that may be more useful to help users hone in on what they are

looking for.

A semantic search engine tries to grab ‘affective’ aspects of web content, especially in the blogosphere or in twitter

feeds.

A semantic search engine can be more than a recommendation service. It can be used to

match people with a need.TrialX used advanced medical ontologies to combine electronic health

records with user-generate information to match people with potentially helpful clinical trial.

Take the time to keep up-to-date with search developments in order to excite students about the real meaning of the world-wide-web.

1- Handling morphological variations (tenses, plurals etc)

2- Handling synonyms with correct senses (cure, heal, treat,.. etc.)

3- Handling generalizations (disease = GERD, ALS, AIDS, etc.)

4- Handling concept matching ("what treats headache" needs concept matching such

that migraine belongs to the concept of headache in the medical sense.)

5- Handling knowledge matching (swine flu = H1N1, flu=influenza.)

6- Handling natural language queries and questions (what, where, how, why, etc.)

7- Ability to point to uninterrupted paragraph & the most relevant sentence

8- Ability to enter queries freely, no special formats like quotes, or Boolean

operators

9- Ability to operate without relying on statistics, user behaviour, and other

artificial means

10- Ability to detect its own performance

Query, browse, gather, curate and share selected information from many sources and mediums.

The real intelligence is in the connections,

and the semantic web is helping to develop ways of understanding the relationship between things.
