A computer-implemented method, according to one embodiment, includes: sending one or more instructions to a web crawler to identify presentation videos on the internet and capture video data therefrom. In response, video data which corresponds to various presentation videos on the internet is received from the web crawler. The video data is used to define influence factors, such that different combinations of the influence factors represent different conditions of a presenter in the presentation videos. The video data is also used to define labels, where different combinations of the labels represent different conditions of one or more audience members in the presentation videos. Furthermore, structured data is generated by correlating certain presenter conditions with certain audience conditions, and the structured data is stored in memory.
