Our pleasure, Marcia :-)

What you found is a basic categorisation that wik.me uses to group concepts - mainly for page presentation purposes.  wik.me/1 is what you get when it can't find any concept that closely matches your search.

The real "taxonomy" is derived from WordNet - the top level concepts can be traced directly to WordNet noun synsets.  WordNet is a fantastic resource, and this has been a common strategy.  Root is "entity" at http://wik.me/2s .

I mentioned in my first post to this forum that our aim was to create a structure that could serve as a kind of devolved universal ontology/universal data schema. The challenge has been to find a structure that maintains this universality, but still offers some usefulness.  What we have at the moment has even fewer axioms than WordNet - and I'm sure we could introduce more.  It's a work-in-progress, and I'd certainly value the input of anyone on this forum who is interested.

I happen to find the taxonomy behind wik.me, starting from the high level:  

• organization   
• person   
• production    
• location   
• event   
  

http://wik.me/1#foundPages

At each ‘category’ there is also a synonym ring, for example, e.g.:

Person

Of people, organism and causal agent     May also be referred to as individual, mortal, somebody, someone and soul.

A human being; "there was too much for one person to do".

It would be interesting to see the taxonomy, for example, ‘shape’ is the first under ‘people’.

Pavithra, I think you must have misspelled "Einstein".   http://search.wik.me/search.htm?words=Albert+Einstein  returns 20+ concepts named for Albert Einstein - and the topmost result is the man himself.  And that list is something you CANNOT get from Google.

Clicking the top result http://wik.me/lfn2 ("Albert Einstein") also gives you something you can't get from Google - a self-organised presentation of what wik.me <http://wik.me>  "knows" about Einstein.  Google knows *nothing* about Einstein but where to find pages that contain the string "Albert Einstein".

Structured data is always going to permit greater functionality than keyword indexing.  If it didn't, you and I wouldn't have a job ;-)

But of course Google is more robust - it would have detected your spelling mistake and given you the most-likely valid alternative.  So it should be with 2000 engineers and over a decade of refinement.

wik.me <http://wik.me>  can also only return results based on the data it has mapped, which means it's a valid alternative to Google for only a minority of searches.  Our estimates suggest that with all organisations, products and services in, we should give a much better experience for around 65% of all searches currently made against Google.  That's next.
