                    This site uses word similarity to score all dragon names from George R.R. Martin's 
                    <a href="https://en.wikipedia.org/wiki/Game_of_Thrones" target="_blank">A Song of Ice and Fire</a> 
                    universe in terms of their "closeness" to the given name. 
                    The dragon name that is the "closest" is the one selected as the user's dragon.
                </p>
                <p>
                    It uses three popular techniques in 
                    <a href="https://en.wikipedia.org/wiki/Natural_language_processing" target="_blank">NLP</a>
                    to calculate similarity scores - these are the 
                    <a href="https://en.wikipedia.org/wiki/Levenshtein_distance" target="_blank">Levenshtein Distance</a>, 
                    <a href="https://en.wikipedia.org/wiki/Cosine_similarity" target="_blank">Cosine Similarity</a>, 
                    and <a href="https://en.wikipedia.org/wiki/Jaccard_index" target="_blank">Jaccard Similarity</a>.
                </p>
                <p>
                    The final result shown to the user uses cosine similarity only,
                    but top ranking dragons from each of the other two techniques are 
                    also shown as alternatives.
