Background: Despite existing research on text mining and machine learning for title and abstract screening, the role of machine learning within systematic literature reviews (SLRs) for health technology assessment (HTA) remains unclear given lack of extensive testing and of guidance from HTA agencies. We sought to address two knowledge gaps: to extend ML algorithms to provide a reason for

    Sep 01, 2021 The complete text mining work is available in Chapter12-1b.xlsx and Chapter12-1c.xlsx. Chapter12-1b.xlsx does not make use of the function TEXTJOIN, while Chapter12-1c.xlsx does. A careful examination of our result reveals that our text mining model does not work well for reviews 9, 15, 16, 20, and 26. This does not mean our mining job is a
