I decided to put the much heralded WolframAlpha to the test with the obvious word - dyslexia, just to see how it faired. I think my response at this level must be "nothing to write home about". Here are the results.
Input interpretation: dyslexia (English word)
Definition: Noun - dyslexia - impaired ability to learn to read
Word origins: German | Greek (first recorded use: 1887 (122 years ago))
American pronunciation: (This does not appear to show well here.)
Broader terms: learning disability / learning disorder
In response to "How do you make a concept map?" it responded "Wolfram|Alpha isn't sure what to do with your input."
At least when I put the same question to Google it gave me half a dozen good answers.
