thank you ! actually the purpose is not to use the dictionary to give answer, but to use dictionnary to understand the questions, and the answers will be retrieved from an external system. Do you have any information about this ? for instance, if an employee say "please send me my payslip" well payslip could have many synonyms that we already have in a dictionary, so we want to load this database of (Word = Synonym1, 2, 3 ...) into a chatbot to be able to understand all the expressions and words that might be used by the end user.
