A more refined version of the AI might be able to distinguish between real PhD jobs in university and research organizations, those in industry requiring Professional Doctoral level skills and those where a Masters would be sufficient, but this would be difficult.
"There is a large ‘hidden job market’ for PhD graduates in the Australian workforce. Only 20.7 per cent of non-academic job ads (2,770 of 13,379 unique job titles) in our dataset asked for a PhD qualification, yet as many as 43 per cent (210 of 483) of the unique job ads that were analysed 3 required a high level of research skills and capabilities, indicative of a PhD. ...
The Machine revealed some interesting
patterns regarding demand for research skills, particularly in industries traditionally assumed to have low demand for PhD graduates, such as manufacturing, transport, logistics, marketing and communication. In addition, other industry sectors were shown as potentially ready to embrace more graduates with research skills, echoing the thinking of the innovation agenda."
