| PrefLib : A Library for Preferences Menu ▾ ❖ Format ❖ Datasets ❖ Search PrefLib PrefLib is a reference library of preference data maintained by Nicholas Mattei and Simon Rey . The original version of this website was developed by Nicholas Mattei and Toby Walsh . We aim at providing a comprehensive resource for the multiple research communities that deal with preferences: computational social choice, recommender systems, data mining, machine learning, combinatorial optimization, to name just a few. The strength of PrefLib is to provide carefully curated data, formatted in a unified format. We encourage the users to read the detailed explanations that we provide regarding the format and the modelisation choices. Once everything is clear, feel free to explore the datasets we are hosting, or to search for specific files that may interest you. PrefLib-Tools Providing data is only the first step, the next one being actually using the data. To help you with that, we provide a Python library |
