摘要:This contribution presents two projects: EuporiaRhetorica and the Digital Lexicon of Ancient Rhetoric (DiLAR). DiLAR aims at creating a lexicon of Latin and Greek rhetorical terminology from the annotation of texts. EuporiaRhetorica is thetool developed by Federico Boschetti, by which the authors are proceeding with the annotation of the rhetorical texts that will constitute the DiLAR. The Euporia method firstly requires a context-free grammar to define the formal annotationlanguage. Secondly, it needs a parser to interpret the language and represent its tree structure (AST: Syntax Tree). Finally, Euporia requires a visitor to pass through each tree node to perform operations or serialize the language differently. In particular, the contribution highlights the advantages of the Euporia method applied to the annotation of texts at the thematic and lexical level through the case study of Cicero’s rhetorical texts and the Rhetorica ad Herennium.
