Re: Checking if a list of names appears in a body of text.

have you considered a decision tree built from your list of company names?

I have a list of company names (say, IBM, Corning, General Motors, and
another 5,000 of them).

If I take a body of text, a news article, for instance, and I want to
see which company names appear in that text, is there an efficient way
to do this?

I thought about looping through the array of names, and doing an
IndexOf or Regex match, but this method is slow. Then I thought about
an array intersection, but this is problematic for two-word company
names (you can't just create the second array based on a split on
spaces).

Any hints would be much appreciated!
