Using auto-ethnomethodology
Harold Garfinkel outlines this documentation approach, drawn from Karl Mannheim's "documentary method of interpretation" (Garfinkel 1967, 78), which bears significant parallels to the concept of semiotics: this method treats the actual appearance of an activity (arguably the signifier) as evidence "documenting" that activity's underlying pattern (that which is signified). For instance, a writer marking a draft-in-progress with the note "Hmm, now where does this go from here?" is an observable, recordable signifier documenting the underlying cognitive pattern of composition (signified), which can be examined and interpreted by the observer.
