12. A system comprising: a document repository to store a plurality of documents; a comparison engine comprising: a vector generator to generate a vector for each of a new document and a document from the document repository, wherein: the vector comprises a number of elements equal to a number of terms of interest; and for each term of interest, an associated element value of the vector is assigned as zero if the term of interest does not occur in the document, and one if the term does occur in the document; and a similarity generator to determine a similarity between the document and the document from the document repository, the similarity based on the vector for the new document and the vector for the document from the document repository, wherein to determine the similarity between the document and the document from the document repository comprises calculating a cosine measurement of similarity between the vector for the new document and the vector for the document from the plurality of documents; and a pairing engine comprising: a document receiver to receive the new document to be paired with the documents in the document repository; a document submitter to submit the new document to the comparison engine and direct the comparison engine to determine a similarity between the new document and each document of the plurality of documents in the document repository; and a pair indicator to indicate a pairing between the new document and a document in the document repository having the highest similarity with the new document if the similarity between the new document and the document in the document repository having the highest similarity with the new document is greater than or equal to a threshold value; and a merge engine comprising: a document receiver to receive a new document to be incorporated with the documents in the document repository; a document submitter to submit the new document to the comparison engine and direct the comparison engine to determine a similarity between the new document and each document of the plurality of documents in the document repository; a merged document generator to generate a merged document by combining at least a portion of the new document with at least a portion of a document in the document repository having the highest similarity with the new document if the similarity between the new document and the document in the document repository having the highest similarity with the new document is greater than or equal to a threshold value; a document remover to remove the document in the document repository having the highest similarity with the new document; and a merged document adder to add the merged document to the document repository; wherein the vector generator further generates a new vector for the merged document.

The system of claim 12 , wherein the merge engine is further configured to: submit the merged document as a new document to the pairing engine.
