How can relationships between texts be recovered as their wording changes?

My research examines textual relations under transformation: how connections between texts persist from quotation through semantic-preserving rewriting and lexical obfuscation to allusion, as lexical and structural similarity progressively weaken.

My work develops and evaluates computational methods to represent, retrieve, rank, and visually analyse these relations across large textual collections, particularly where lexical overlap is weak or absent.
