                      Problem
                           4


 Each application domain uses its own terminology

 Formal languages are difficult to understand by non-

 specialists

 Domain experts prefer natural language in order to

 describe a problem

 Make sure that the author stays within the controlled

 natural language
                      Outcome
                           5


 Prototype able to guide the writing process of an

 author

 Provide tailored output according to the author’s

 need

 Domain specialists do not need to learn a formal

 language

 In relation to the project
   Importance on having an initial plan

   I appreciated the help that your supervisor can provide

 In relation to the topic of the project
   Natural language can be very ambiguous that is why controlled
    natural languages are used and a good interface that provides
    writing support becomes a very important component.
   A good way to guide a user in a constraint environment is to
    give him the approved vocabulary and let him define new
    words in a systematic way
