1. A method comprising: operating a switch to release a document viewer activation control to a first selector, in response to receiving an activation input for a document viewer through an application interface; configuring the first selector with the document viewer activation control to: select application location for the application interface from the document viewer activation control; select document view logs, each associated with a document identifier, with document view entries each comprising a time stamp, and view location matching the application location, from a view log memory allocation of a controlled memory structure; and release the document view logs to document prioritization logic; configuring the document prioritization logic with the document view logs to: calculate average document view rate for the application location from time stamp intervals between the document view entries; calculate an average view rate for each document of a plurality of documents at the application location from the time stamp intervals between the document view entries for each of the plurality of documents; normalize the average view rate for each document with the average document view rate; weight normalized average view rates through operation of a relevance modeler to generate relevancy scores; operate a combiner to rank the relevancy scores in descending order and combine in a document relevance set; and release the document relevance set to a second selector; configuring the second selector with the document relevance set to: select the plurality of documents, from a document collection memory allocation in the controlled memory structure, with matching document identifiers to the relevancy scores; and release each document and the document relevance set to the document viewer in the application interface; configuring the document viewer with the document relevance set to prioritize rendering of each document based on associated rank of the relevancy scores; operating the switch to release a document view signal to a compiler, in response to a document viewing in the document viewer; and configuring the compiler with the document view signal to: identify a document view log for a viewed document, through the matching document identifiers, in the view log memory allocation; generate a new document view entry for the document viewing in the document view log; append the application location of the application interface during the document viewing in the new document view entry as the view location; and record a new time stamp from a clock in the new document view entry for the document viewing.
