Background
The public conception of scientific expertise is, at times, slanted by mistrust especially in relation to several public health issues, e.g., vaccination, autism, and Covid-19. How
Methods
For bag-of-words representation $X$ w. documents in columns and words in rows, such that each entry $X_{ij}$ is the $i$th word in the $j$th column, we solve
\begin{equation} \underset{W,H}{\mathrm{argmin}} \parallel X - WH \parallel^{2}_{F} ~~~ s.t. ~ W,H \geq 0 \end{equation}
