Artificial intelligence (AI), Machine Learning (ML), Deep Learning (DL) – since the start of the
Fourth Industrial Revolution, these buzzwords have been trending and sometimes falsely used as
synonyms for each other [1, 2]. The technologies associated with AI are mainly responsible for
advances in many fields like image and speech recognition. Since AI technologies can be applied
to a wide range of fields including medical and education fields, many efforts have been actively
given to identify the current technology trends and analyze development directions of it. [3, 4, 5].
Podcasting has emerged as an important information technology tool for health professionals and
consumers around the world . An initial literature research indicated, that there is a lack of
research using podcasts as a data set for trend analysis.
The goal of this thesis is to review the major research trend on the topics of AI, ML and DL using
trend analysis on health-care podcasts. A representative amount of trending health-care podcasts
will be screened and selected. All their podcasts will be downloaded and transcribed to text using
a Speech-to-Text API. The resulting text data will be used for quantitative trend analysis and to
research how the buzzwords around AI and its subsets have evolved over time.
