Charles is studying a corpus and he found the following absolute frequencies of occurrence (indicated by the function C(word)) for the given words. In addition, this corpus contains 164,000 tokens and the number of distinct word-types is 6,250.

Charles knows that it is important to apply a smoothing techniques for each estimate. However, he does how to apply any of them. Choose one smoothing approach and apply to the different occurrence estimate. What is the main advantage and drawback of your proposed solution?

\begin{tabular}{|c|c|} \hline Word & C (word) \\ \hline & 8,200 \\ \hline the & 456 \\ \hline new & 11 \\ \hline solution & 42 \\ \hline is & 321 \\ \hline very & 5 \\ \hline good & 25 \\ \hline \end{tabular}
