Preference relations based unsupervised rank aggregation for metasearch

作者:

Highlights:

• We propose a preference relations based unsupervised rank aggregation algorithm.

• The algorithm gives weights to input rankers depending on their qualities.

• Ranker quality is estimated in unsupervised way using a variant of majority opinion.

• Performed experimental evaluation using supervised and unsupervised metrics.

• Kendall-Tau distance not suitable for evaluating metasearch algorithms.
