Query: Collecting, Classifying, Analyzing, and Using Real-World Elections   We present a collection of $7582$ real-world elections divided into $25$
datasets from various sources ranging from sports competitions over music
charts to survey- and indicator-based rankings. We provide evidence that the
collected elections complement already publicly available data from the PrefLib
database, which is currently the biggest and most prominent source containing
$701$ real-world elections from $36$ datasets. Using the map of elections
framework, we divide the datasets into three categories and conduct an analysis
of the nature of our elections. To evaluate the practical applicability of
previous theoretical research on (parameterized) algorithms and to gain further
insights into the collected elections, we analyze different structural
properties of our elections including the level of agreement between voters and
election's distances from restricted domains such as single-peakedness. Lastly,
we use our diverse set of collected elections to shed some further light on
several traditional questions from social choice, for instance, on the number
of occurrences of the Condorcet paradox and on the consensus among different
voting rules.
