Why use such complicated stuff, which is concerned with numbers, probability, density, tests, and all that which we hated in school? Why oh why?!
Fact is, archaeologists produce huge amounts of data.
The well known Austrian information scientiest Gerhard Chroust wrote an article “Software-Archäologie: Eine interdisziplinäre Betrachtung” (“software-archaeology: an interdisciplinary view”) in which he compares the maintenance of software with archaeology. It is a kinda cool and funny article, really.
