The Digital Plato Project ( developed tools for paraphrase search that enable a completely new, web-based analysis of texts. Using the rWMD (relaxed Word Mover’s Distance), paraphrase candidates can be identified in digitized text corpora; the reference annotator can be used to comment on the relationships between the found text passages in different categories and the search based on complex n-grams enables to model different paraphrase terms for different search queries.
