Replace multiple consecutive occurrences of a character with a single occurrence

Question

I am making a natural language language processing application in Java, I am using data from IMDB and Amazon.

I came across a certain dataset which has words like

Answer 1

There are no English words that I know of that have more than two consecutive identical letters.

1. Iterate over all words
2. If the word has more than two consecutive identical letters, then:
   • Remove all but two of the duplicate letters, and see if a valid word is formed.
   • Otherwise, remove all but one duplicate letter, and see if a valid word is formed.
   • Otherwise, fail.

This approach would not catch:

• partyy

• "stoop" (plus that's ambiguous! Is that "stop" with an extra "o" or simply "stoop")
