[~,c] = ismember(word,uniqueWord);
out = [uniqueWord, num2cell(accumarray(c,1))];

You can use the strcmp (string compare) function to search for matches with a particular word. Then, you can use the nnz (number of non-zeros) function to count the number of hits.
For example:
>> nnz(strcmp(word,'sleep'))
ans =
10
You can then either loop through all the words you want to search for, or you can look into cellfun to apply the same code as above for all elements of the uniqueWord array. Up to you.
