Conceitos essenciais
Course recommender systems should incorporate real-time job market trends and skill demands to provide learners with course recommendations that enhance their employability and career prospects.
Resumo
The paper presents the perspective of academic researchers working in collaboration with industry practitioners to develop a job-market-oriented course recommender system. It identifies key properties such a system should have:
- Aligned with the latest job market trends to prioritize courses teaching high-demand skills.
- Unsupervised to adapt to the rapid evolution of the job market without the need for extensive manual data labeling.
- Sequential to recommend a progression of courses where each course builds upon the previous ones.
- Aligned with users' goals such as attaining a specific role or increasing their overall marketability.
- Explainable to ensure user trust and engagement.
The paper also outlines several research directions to address the challenges in developing such systems, including:
- Creating or providing datasets for training and evaluating course recommendation models.
- Designing evaluation metrics that consider alignment with the job market.
- Estimating users' goal progress and tailoring recommendations accordingly.
- Developing skill-based explainable models and visualization techniques.
- Designing unsupervised skill matching and taxonomy construction methods to keep up with evolving job market demands.
The paper also introduces an initial system, SEM and JCRec, that addresses some of the existing limitations of course recommender systems. SEM uses large language models for unsupervised skill extraction and matching, while JCRec employs reinforcement learning to recommend course sequences that maximize the number of job opportunities available to the user.
Estatísticas
The contemporary job market is dynamic and rapidly evolving, necessitating continuous adaptation of individual skill sets.
There is a notable mismatch between the skills learners possess, the skills taught, and those in demand in the job market.
Existing course recommender systems often focus solely on learner-course dynamics, neglecting the crucial aspect of aligning recommendations with real-time job market trends.
