            length of 120 is an empirical value which should reflect the length \
            of a “context” and should limit the paragraph length deviation. \

            SDG 16 “Peace, Justice and Strong Institutions” and SDG 17 \
            “Partnerships for the Goals” are excluded from the analysis due to \
            their broad nature which could potentially inflate the results. \

            displayed in a summary table including the number of the SDG, a \
            relevancy score highlighted through a green color shading, and the \
            respective text of the analyzed paragraph. Additionally, a pie \
            chart with a blue color shading is displayed which illustrates the \
            three most prominent SDGs in the document. The SDG classification \
            uses open-source training [data](https://zenodo.org/record/5550238#.Y25ICHbMJPY) \
