# Most influential database papers

Ever wondered which database systems papers have been the most influential? This page explores the PageRank of a paper in the citation graph, one possible measure of influence.

All rankings, including this one, codify an ideology and thus wonâ€™t match up with everyoneâ€™s understanding of â€śinfluence.â€ť Most notably, this ranking has nothing to do with industrial adoption, actual usage, or quality of an idea, other than by correlation with citation. Note that the citation graph grows every year, so papers published more recently will, on average, have a lower score.

PageRank is computed with the Python package NetworkX on top of the citation graph of all SIGMOD, VLDB, and CIDR papers. Self-citations are excluded. Absolute and percentile ranks are then computed for each paper using the PageRank score. Authors are ranked according to the sum of their paperâ€™s PageRank score, where each paperâ€™s score is divided by the number of authors, similar to CSRankings.

## Most influential papers, by year

This is a list of papers published in a particular year, sorted by their PageRank score. You can select a different year from the dropdown. Papers published in recent years have fewer citations, and thus more noise in their score.

## Most influential people

This table ranks all authors of a VLDB, SIGMOD, or CIDR paper that has been cited at least once (by another VLDB, SIGMOD, or CIDR paper). An authorâ€™s score is the sum of their paperâ€™s normalized PageRank score. The normalized PageRank score of a paper is the PageRank score of the paper divided by the number of authors on the paper.

Due to the exponential distribution of PageRank scores, the most influential papers have significantly higher scores than the median paper. As a result, authors of the most influential papers will rank highly here, even if they have few papers overall.
