Rapid miner functionnalities

Hello,
I am starting a new project and I am looking for the solution which could be the most suitable for it. I started to build some small processes with Rapid Miner using text mining extensions.
Now, I would like to know if the following functionnalities are possible with this solution :

1. Is there an operator to work with synonymous ?

2. A dictionnary node ? To detect specified word and excludes specific ones.

3. A node which recognize dates format ?

4. Navigate in the document by clicking on the result word set

5. Finally, is it possible to have an end user interface, I mean to build it in that way non IT people could use it by navigating in the document

Thanks a lot !
