A Survey on Intent-aware Recommender Systems
Dietmar Jannach, Markus Zanker

TL;DR
This survey reviews recent advances in intent-aware recommender systems, highlighting technical approaches, evaluation practices, and future research directions to improve personalization by understanding user intent.
Contribution
It categorizes existing intent-aware recommendation methods and discusses evaluation gaps, proposing future directions including richer interaction signals and context integration.
Findings
Diverse technical approaches like intent prediction and latent modeling exist.
Current evaluation practices have notable gaps and limitations.
Future research should incorporate more interaction signals and contextual data.
Abstract
Many modern online services feature personalized recommendations. A central challenge when providing such recommendations is that the reason why an individual user accesses the service may change from visit to visit or even during an ongoing usage session. To be effective, a recommender system should therefore aim to take the users' probable intent of using the service at a certain point in time into account. In recent years, researchers have thus started to address this challenge by incorporating intent-awareness into recommender systems. Correspondingly, a number of technical approaches were put forward, including diversification techniques, intent prediction models or latent intent modeling approaches. In this paper, we survey and categorize existing approaches to building the next generation of Intent-Aware Recommender Systems (IARS). Based on an analysis of current evaluation…
