            document. Thereafter, the user can choose between two categories \
            to compare coherence between the documents: climate change adaptation \
            and climate change mitigation. Based on the selected information, \
            the application identifies relevant paragraphs in the uploaded \
            document and assigns them to the respective indicator from the NDC \
            Explorer. Currently, the NDC Explorer has 20 indicators under \
            climate change mitigation (e.g., fossil fuel production, REDD+) and \
            22 indicators under climate change adaptation (e.g., sea level rise,\
            investment needs). The assignment of the paragraph to a corresponding\
            indicator is based on vector similarities in which only paragraphs \
            with similarity above 0.55  to the indicators are considered. """)
