Replacing text from dictionary

I tried to replace abbreviations with their expansions from dictionary. But it needed splitting of sentences.

Then I tried using the recursive loop to achieve the same, but  it proved very slow.

My problem is , is there any way to automate spliiting and then running the replace(dictionary) on each column for any number of columns generated?

You can split the cell using the Cell Splitter node and then use the Column List Loop Start node to iterate over the resulting columns. Though my guess is, that this is also very slow.

Maybe there are some more convenient nodes in the Text Mining extension?
