In order to optimise the quality of the summary to be processed, it is essential that the words in the text to be analysed are spelt correctly and recognised by the vocabulary of the selected language. By enabling the spell-checker, you will be able to identify any terms that are not spelled correctly or not recognised in the vocabulary of the selected language. If you believe that an unrecognised term should be added to Nelsenso.Net's vocabularies, you can add it. If this addition is approved, it will be available the next day.
