Clustering methods are applied regularly in the bibliometric literature to
identify research areas or scientific fields. These methods are for instance used
to group publications into clusters based on their relations in a citation
network. In the network science literature, many clustering methods, often
referred to as graph partitioning or community detection techniques, have been
developed. Focusing on the problem of clustering the publications in a citation
network, we present a systematic comparison of the performance of a large number
of these clustering methods. Using a number of different citation networks, some
of them relatively small and others very large, we extensively study the
statistical properties of the results provided by different methods. In addition,
we also carry out an expert-based assessment of the results produced by different
methods. The expert-based assessment focuses on publications in the field of
scientometrics. Our findings seem to indicate that there is a trade-off between
different properties that may be considered desirable for a good clustering of
publications. Overall, map equation methods appear to perform best in our
analysis, suggesting that these methods deserve more attention from the
bibliometric community.
