As a newcomer to this area I tried to define to myself what stands behind this buzzword. My answer is simple: Web 3.0 is about new techniques to organize, retrieve, share and combine information using Graphbases.
We can define four generations of information-organization methods:
| Generation | Method | Data Structure |
| Web 0.0 | Directories | Hierarchical |
| Web 1.0 | Indexing |
Flat |
| Web 2.0 | Tagging (folksonomy) | Flat |
| Web 3.0 | Linking | Graph |
(I guess that every time the volume of the web, i.e. the amount of documents, grows by four or five orders of magnitude, a new technology emerges.)
We can define three basic classes of items we should link together: Objects, Concepts, and Attributes:
-
Objects could be real-world objects (
), desktop objects ( 
) or web objects ( 
) . -
Concepts (
) are representations of abstract topics or categories (e.g. 'service providers'), instances (e.g. Verizon), or concrete objects (e.g. Verizon' CEO) [don't confuse the concept and the real-world object it represents. See the semiotic triangle below].
-
Attributes Includes Tags (
) like "V-e-r-i-z-o-n" or "I-v-a-n-S-e-i-d-e-n-b-e-r-g", as well as Geotags, URLs ( 
), etc.
- When we link attributes to web objects (
) we call it tagging, or indexing if it is done automatically. -
Ontologies, Taxonomies and/or Topics Maps, link together concepts:
- Semiotic triangle looks like
Graphbase is an information-base based on graphs in a fashion that can work at Internet scale. When URIs ( 
) are used to annotate information items, items can be uniquely identified, so Graphbases allow data to be processed outside the particular environment in which it was created.
Combining together concepts, tags, objects and URIs we can create simple Graphbase like:
In the Web 3.0 environment there will be multiple different applications and ways to use Graphbases for exposing, sharing, and connecting pieces of data, information, and knowledge. For example:
-
Intra-document information analysis based on domain ontologies to identify the latent knowledge found in text. In simple words, it enables better search engines.
-
Inter-document data-web: linking together heterogeneous objects enabling better browsing.
-
Extract structured meaning (i.e. concept-attribute pairs) from documents, and linking them to the document to present knowledge in a standard form, permitting software agents to better find and combine information.
- ...
So, to summarize this simplistic view, Web 3.0 is about new ways to organize and retrieve information.
The next question one would like to answer is "when does it worth the effort?" In other words, "why and when indexing and tagging are not good enough?" I am not sure I have good answers yet, so I will be happy to have some feedback on this.
Cheers,
Gil'ad

It is a very user friendly, web-based application that is well worth taking the time to explore. Take a few minutes and look at Projjex.com. The tutorials are excellent & you don't need to be a Rocket Scientist to figure out how to use it. It even offers a free version so you can try it on for size. |
