We are final year computer engineering student making project on human resource development and management. We want to implement artificial intelligence in our software. we are having very vast emplyoee data. But we dont have any idea about AI. for eg. if we input 10 employee names then the team leader should be given by the software depending upon knowledge base. we are bounded to some time limits so we request you all to help us as soon as possible.

Perhaps a good place to start is the resources page of this website.

I'd recommend against attempting to implement AI when you know nothing about it and have limited time. It will take you months to understand anything appart from basic concepts of AI.

Your problem description is pretty vague, but I would opt for an expert system in that case.

I think your problem is not about AI. You don't have to use ai algorithms.You should use ordering algorithms.
You should order people with criterion such as success , intelligence ,abilty...If 10 people was given to your sofware , program should select the team leader with the important criteria .If you ask your program for advertisement department , your program can select the leader who has the top creative rating ..
I think it is not easy but in other case ,AI is much more harder solution to your problem.
