Community Question Answering (CQA) websites such as Stack Over ow provide a great platform to ask questions and get answers. Such platforms serve the purpose of helping the community of people who look for answers. The platforms thrive as a result of a small group of people known as experts who provide quality answers to question posters. There has been a lot of work to determine experts in CQA websites, make predictions about po- tential experts and predicting how their answering behaviour varies over time. There may be a situation where some experts were aggressive contributors to the community at some point in time. But gradually their contributions started to diminish and they may also finally stop contributing in future. We have presented an approach to rank the experts in the community as a function of time. Exper- tise score of an expert shows how good the expert is. Higher the expertise score, better expert the person is. Our metrics to calculate the expertise score are modifications of the existing expertise ranking metrics such that it incorporates durations of inactivity of the expert in the community while ranking them.
