The issue that Krzysztof raises with Wik.me concerns the ultimate purpéose of why you want look up anything and what that anything is in terms of semantic primitives (i.e.the most genric terms that there are in NLP to be used in semantic analysis)

Subject: Re: [ontolog-forum] the data mining craze
Frankly speaking I am having a hard time making sense out of wik.me. For instance, I typed in Germany and got about 30 results in the 'Germany may include' list. Most of them were about German soccer teams, heavy metal bands, or the city Ogden in Utah. From my perspective this list does not follow any order nor does it contain relevant links about Germany in general (leaving the first link aside). The 'Around the Web' section lists some links also contained on the first page
of a Google search for the same term. After following the first link from the 'Germany may include' list, I get a single sentence definition of Germany and then a category called 'Contains'. This category seems to be spatial containment at first but it is not. I lists some German cities, some German states, the Oktoberfest, the German term 'Schadenfreude' and so forth. All this comes without any further *structure* and is rather confusing. After clicking on the city Duesseldorf, I don't get any additional results but just the around the Web section. Powerset.com, for instance, followed a similar but way more advanced approach in 2008 before they got bought and closed by Microsoft. The same is true for Freebase and other projects that provide structured data. Again, maybe I just used the wrong terms for testing, but I do not see where wik.me is going or who will use it.

Our pleasure, Marcia :-)
What you found is a basic categorisation
that wik.me <http://wik.me> uses to group concepts - mainly for page presentation purposes. wik.me/1 <http://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.

Very general concepts included in wik.me are not subclasses of anything
in this list. A top-level concept that SHOULD include all of these is
"Entity", defined as "That which is perceived or known or inferred to
have its own distinct existence (living or nonliving)." I suppose
things like "corner" would not be entities, since they have no
independent existence.
I don't see that wik.me has a taxonomy. It has concepts, which are
specified as "of" one or two other concepts. This "of" can
sometimes
mean a subclass relation, sometimes mean an instance of relation, and
other times have other meanings.
For example, the "Corner" which is defined as "an interior angle
formed by two meeting walls" is "of" both "building" and "area".
The listed set leaves things such as organisms out. One would think
that they all should be subclass of "Entity". If you follow some type
of animal up the hierarchy, you find at many levels it is "of" both
the next more general taxon AND "of" the current taxon type. E.g.,
the concept "Chordata" is "of" both "phylum" and "Animalia". However,
"Animalia" is only "of" "kingdom", it is not "of" "Organism". The
concept "animal" is "of" both "Animalia" and "Organism", but no chain
of "of"s links concepts for most types of animals to the concept "animal".
Wik.me provides some interesting results, but it is no taxonomy.
