Package recommender systems: A systematic review
S.N. van Schaik, Judith Masthoff, Agung Toto Wibowo · Intelligent Decision Technologies · 2020
This paper presents a systematic review of research into package recommender systems (PRS). PRS recommend a combination of items rather than individual items, for example, multiple attractions to visit on a day trip to a city, trousers and a shirt to wear together, or multiple dishes to make up a m eal. The review provides a framework for considering existing PRS research, and highlights the techniques used for package recommendation and the evaluation methods and metrics employed. It also raises many issues that warrant future research.
