Cold-start and data sparsity problems in a digital twin based recommendation system
| Resumo: | The emergence of Digital Twins (DT) in Industry 4.0 has enabled the decision support systems taking advantage of more effective recommendation systems (RS). Despite the RS’s growing popularity and ability to support decision-makers, these face two significant challenges, cold-start and data sparsity, which limits the system’s capability to provide effective and accurate decision support. This paper aims to address these issues by conducting a literature review, analysing the current research landscape, and identifying the main enabling methods, algorithms, and similarity measures to mitigate these challenges. The performed analysis enables the point out of future research directions for developing effective and accurate RS that empower decision-makers. |
