Enriching the ToE dataset

• Several AgendaItem instances have the same title over years

• Track the evolution of topics in debates related by the same title

• Triplifying speeches text • Tools: LDA package, TextRazor API • Output: - Topics for sets of Speech instances with same date and title - Wikipedia/DBpedia pages describing the extracted topics
