8. A method for assessing similarity of documents, comprising: extracting a reference document text from a reference document; extracting an archived document text from an archived document; quantifying the reference document, comprising: tokenizing reference document sentences of the reference document text; and vectorizing the tokenized reference document sentences to obtain a plurality of reference document paths; quantifying the archived document, comprising: tokenizing archived document sentences of the archived document text; and vectorizing the tokenized archived document sentences to obtain a plurality of archived document paths; determining a document similarity value of the quantified reference document and the quantified archived document, comprising: selecting a first reference document path from the plurality of reference document paths; selecting a first archived document path from the plurality of archived document paths; making a first determination that a length of the first reference document path is different from a length of the first archived document path; based on the first determination: identifying a shorter path and a longer path of the first reference document path and the first archived document path; generating subsequences from the longer path, with a length matching the length of the shorter path; calculating a path similarity value for the shorter path and the subsequences; adding the path similarity value to a sum, wherein the sum is the document similarity value.

The method of claim 8 , further comprising: making a determination that the document similarity value is above a minimum similarity threshold; and based on the determination: reporting the archived document to a user.
