Self-executing document revision includes creating a current version of an electronic rendering of a collaborative document based on input received from a user via a communicative coupling with a data communications network. The current version's relevancy is determined by a self-executing document revisor and compared with the relevancy of a prior version of the collaborative document. In response to determining the relevancy of the current version is less than the relevancy of the prior version, one or more segments of one or more electronically stored versions of the collaborative document are selected based on a relevancy of each of the one or more segments, the relevancy of each determined by the self-executing document revisor. The self-executing document revisor generates a graphical representation of a revised version of the collaborative document by merging the one or more segments selected with the current version of the collaborative document.
