Methods of Investigation
Already in use• Simple word selection/word count (Tock,
Brousseau, Parisse)• Phrase statistics (Gervers/Margolin)• Graphetic detail analysis (Fiebig)• Hand identification by pattern analysis
(Schomaker/Burgers)• Named entity recognition
(Stoyan/Schmidt)

Possible Programming
Testing/adapting existing algorithms• Author identification tools• Graphical variation tools• Named Entity Recognition methods for clauses
to find the connections between charters that aren’t kept in the same archive/aren’t printed in the same edition:• e.g.: Influence of recipient on the charters• Spread of formula, regions of legal culture
