  Reviewing scientific literature is a cumbersome, time consuming but crucial
activity in research. Leveraging a scholarly knowledge graph, we present a
methodology and a system for comparing scholarly literature, in particular
research contributions describing the addressed problem, utilized materials,
employed methods and yielded results. The system can be used by researchers to
quickly get familiar with existing work in a specific research domain (e.g., a
concrete research question or hypothesis). Additionally, it can be used to
publish literature surveys following the FAIR Data Principles. The methodology
to create a research contribution comparison consists of multiple tasks,
specifically: (a) finding similar contributions, (b) aligning contribution
descriptions, (c) visualizing and finally (d) publishing the comparison. The
methodology is implemented within the Open Research Knowledge Graph (ORKG), a
scholarly infrastructure that enables researchers to collaboratively describe,
find and compare research contributions. We evaluate the implementation using
data extracted from published review articles. The evaluation also addresses
the FAIRness of comparisons published with the ORKG.
