La logica fuzzy e le sue applicazioni alla ricerca archeologica

This paper deals with the application of fuzzy logic to archaeological research. Fuzzy logic is based on a continuum of truth values ranging from 0 (False) to 1 (True) and thus may help whenever there exists some uncertainty on data assignment to predetermined categories. After examining the features and drawbacks of typological classification and the problem of gender and age assignment in cemetery excavations, the fundamentals of fuzzy logic are summarized. Four examples of archaeological applications are then presented. The first example deals with a necropolis in which tombs present a high degree of uncertainty as far as sex and age of the deceased are concerned. Therefore it is suggested to use a fuzzy database management system, i.e. a DBMS implementing fuzzy logic and function, for data storage and processing. Such a database software was previously developed for this application. In the following three examples, classification problems are considered and it is shown how the use of fuzzy logic may change their archaeological interpretation. The authors claim that a generalized use of fuzzy logic, as is widely applied in other sciences, may improve the quality of data processing and above all produce reliable and transparent results, or at least illustrate the degree of reliability the researcher grants to those data
