Query: Benchmarks for Graph Embedding Evaluation   Graph embedding is the task of representing nodes of a graph in a
low-dimensional space and its applications for graph tasks have gained
significant traction in academia and industry. The primary difference among the
many recently proposed graph embedding methods is the way they preserve the
inherent properties of the graphs. However, in practice, comparing these
methods is very challenging. The majority of methods report performance boosts
on few selected real graphs. Therefore, it is difficult to generalize these
performance improvements to other types of graphs. Given a graph, it is
currently impossible to quantify the advantages of one approach over another.
In this work, we introduce a principled framework to compare graph embedding
methods. Our goal is threefold: (i) provide a unifying framework for comparing
the performance of various graph embedding methods, (ii) establish a benchmark
with real-world graphs that exhibit different structural properties, and (iii)
provide users with a tool to identify the best graph embedding method for their
data. This paper evaluates 4 of the most influential graph embedding methods
and 4 traditional link prediction methods against a corpus of 100 real-world
networks with varying properties. We organize the 100 networks in terms of
their properties to get a better understanding of the embedding performance of
these popular methods. We use the comparisons on our 100 benchmark graphs to
define GFS-score, that can be applied to any embedding method to quantify its
performance. We rank the state-of-the-art embedding approaches using the
GFS-score and show that it can be used to understand and evaluate novel
embedding approaches. We envision that the proposed framework
(https://www.github.com/palash1992/GEM-Benchmark) will serve the community as a
benchmarking platform to test and compare the performance of future graph
embedding techniques.
