Indeed, this is a very applied topic, but this does not mean that there 
is no research to be done in the field. Of course, one will have to 
think beyond the existing concepts (semantic wikis are already in wide 
use, so research activities there are limited). As an example of a new 
idea, the Shortipedia project [1] combines semantic wiki technology with 
linked data to let communities edit and integrate data from the Semantic 
Web. This won the third prize in last year's Semantic Web Challenge, and 
shows that there are still some new things to be done in the space.

However, "semantic wiki" is almost as general a topic as "Semantic Web" 
(wikis are Webs in small, aren't they?). You will still have to be more 
specific. A good tactic might be to ask yourself which scientific 
methods you would like to apply for gaining insights (do you implement 
and evaluate? ask users and do statistics? write down mathematical 
proofs?). Moreover, your supervisor should have something to say about 
what kind of topics are in scope for you (obviously, he or she can only 
supervise topics in his/her area of expertise).

You may want to have a look at the proceedings of the annual Semantic 
Wiki Workshop [2] for inspiration. There is also a related mailing list. 
Students who want to do practical work in the field are encouraged to 
participate in our Google Summer of Code programme [3] -- this is rather 
a (quite cool) internship than a research project, but its a good way to 
get to know semantic wikis from a practical side.
