Abstract
New technologies are emerging on a continual basis with drastic trajectories and wider penetration into the job market. Health care is among the top ten sectors in terms of talent turnover rates. Hence, being proactive—by predicting what skills will be in demand, is essential to be prepared for these changes. To predict such transitions, this paper aims to develop a job analysis system with an example from the healthcare field in two countries; United States of America and United Arab Emirates. This empirical research consists of using data science with the help of multiple techniques. To study changes in job demand, we deployed Latent Semantic Indexing (LSI) and Latent Dirichlet Allocation (LDA) models; while for the skill changes we used techniques Factor Analysis and Non-Negative Matrix Factorization. Using different heatmaps visualizations of the LSI and LDA weights, results provided significant insights into the skill sets and demand changes in both job markets. The study concludes that low-skilled jobs are constantly being replaced by automated systems, while some of the high skill sets are also at risk.
