Abstract: Systems and methods for assessing similarity of documents are provided. Embodiments of the systems and methods include extracting a reference document text from a reference document, extracting an archived document text from an archived document, and quantifying the reference document and the archived document. The systems and methods may also include determining a document similarity value of the quantified reference document and the archived document. Determining the document similarity value includes calculating a set of vector similarity values for a set of combinations of a reference document text vector and an archived document text vector, and calculating the document similarity value, including a sum of the plurality of vector similarity values.

Abstract: A method for assessing similarity of documents. The method includes extracting a reference document text from a reference document, extracting an archived document text from an archived document, and quantifying the reference document and the archived document. Quantifying the reference and archived documents includes tokenizing sentences of the reference document and archived document, respectively, and vectorizing the tokenized sentences to obtain a reference document text vector and an archived document text vector for each sentence of the reference and archived document, respectively. The method also includes determining a document similarity value of the quantified reference document and the quantified archived document. Determining the document similarity value includes calculating a set of vector similarity values for a set of combinations of a reference document text vector and an archived document text vector, and calculating the document similarity value, including a sum of the plurality of vector similarity values.
