This visualization depicts the similarity of the works of authors in various fields. The proximity of two authors represent the similarity of their works. The closer they are- the more similar their works (with some approximations). A directed red arrow from author A to author B means that - for author A the most similar author was found to be author B. More technically, the works of each author is represented as an n dimensional vector where each dimension represents a word. The co-ordinate for each dimension is determined as the TF(Term Frequency) * IDF (Relative rarity) of each word. The distance used to measure is the CosineDistance ( 1 - CosineSimilarity).
