4. Problem 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
A controlled natural language is a well-defined subset of a natural language that can be translated unambiguously into a formal language

5. Outcome 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

10. Technologies Used Asynchronous JavaScript + XML (AJAX)
Retrieve data from a server asynchronously in the background without interfering with the behavior of the existing page
JavaScript Object Notation
More compact that XML

Use of session to identify different users

18. Lessons Learned 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
