Abstract
Disclosed is a system for comparing a plurality of documents, wherein each of the plurality of documents comprise one or more sentences the system comprises a lexicon ontology represented into multi-dimensional hierarchical space communicably coupled with a server arrangement. The server arrangement is configured to obtain the documents, tokenize, using a tokenizer module, the sentences in each of the documents to obtain a plurality of tokens for each of the documents, determine token coordinates of each of the tokens in the multi-dimensional hierarchical space representing the lexicon ontology, determine sentence coordinates for each of the sentences in the documents using a transmutation module, generate similarity scores for each of the sentences in the documents using a comparison module, and determine a measure of similarity between the documents based on the similarity scores of the sentences in the documents.
