Looking for a college project

Question

Hello

I'm looking for a project for my 4th year at the Informatics Faculty in Damascus University.

In my college we have to make a project on each year in the last three years (we study informatics for 5 years in college).

My project on the last year was: XMPP Java Implementation.

In this year we need to make a more complicated project, using the software engineering methods, more complicated database usage, a little bit data mining, a little bit information retrieval.

Any new feasible ideas?

My team is consisted of 4 students.

We should be able to analyze, design, implement, test, distribute the project in about 3 months at most.

Thanks in advance.
