6. Conclusions

The academic objects like author, conferences, journals and papers are the main entities to be ranked. In this study, we have studied the methods for ranking of authors and we have classified them according to their way of calculations. There are methods which can rank any one, two or three of the mentioned academic objects but more generic solutions are missing which can be applied to all those academic objects. We observed that most of the work done for the ranking of the authors is in category of link analysis methods. The link analysis based methods use several features like the number of publications, the number of citations, the position of authors, the influence of co-authors, the effect of topic, and different combinations of these features. All the features and their combinations have their own effect on the ranking results and can be used in different scenarios. These methods can give variable results under different situations. For example, if the objective is to find topic-based ranking of authors, a generic method that only uses the number of publications or citations cannot give required results. Similarly, if question is about finding the influence of a senior author on a junior, a topic-based method is not applicable. We conclude that all ranking features have very strong influence on the results of a methods and hence selection of a ranking method must be done keeping in view the required results and objectives.
