I do not think that on the current market, or being developed, there is
a real concept search tool. The key issue is that nobody has offered a
satisfactory answer on what a concept is and its structural formula
(Epistemological solution)before any computer programming language is
applied. What we have now is just a some kind of "keyword linking"
tricks or schemes, similar as what Bill Gates describes, just "a bunch
of links" out of a searching inquiry.
Now, back to the origin of argument, it is that what is a concept, or
say "what is the most fundamental structural unit used to build our
complete human reasoning and human knowledge systems. When you start
asking the right questions, and the right answers should come.
Please visit my web site for the discovery of such basic units, which I
name "Codon" since they are so much resembling (perfect analogy to)the
mechanism and structure (conceptually) of DNA.
Now the website: www.Codonology.com
Good future!
