Multi-Aspect Group Formation using Facility Location Analysis

by Mahmood Neshati, Hamid Beigy, and Djoerd Hiemstra

In this paper, we propose an optimization framework to retrieve an optimal group of experts to perform a given multi-aspect task/project. Each task needs a diverse set of skills and the group of assigned experts should be able to collectively cover all required aspects of the task. We consider three types of multi-aspect team formation problems and propose a unified framework to solve these problems accurately and efficiently. Our proposed framework is based on Facility Location Analysis which is a well known branch of the Operation Research. Our experiments on a real dataset show significant improvement in comparison with the state-of-the art approaches for the team formation problem.

The paper will be presented at the 17th Australasian Document Computing Symposium ADCS 2012 at the University of Otago, Dunedin, New Zealand on the 5th and 6th December, 2012.
