Karine Chemla is currently Senior Researcher at the French National Center for Scientific Research (CNRS), France, in the research group SPHERE (Science—Philosophy—History). Her interest is in the history of mathematics in ancient China within the context of a world history. She also researches modern European mathematics. In both cases, she focuses from a historical anthropology viewpoint, on the relationship between mathematics and the various epistemological cultures in the context of which it is practiced and cultivated. Chemla is more widely interested in the theoretical challenges ancient mathematics raise for history of science. She conducts theoretical work on, for example, algorithms, mathematical proofs, the historians’ sources and notions such as “practice” and “cultures.” Chemla published, with Guo Shuchun, Les neuf chapitres (2004) and edited The History of Mathematical Proof in Ancient Traditions (2012). Since 2011, with Agathe Keller and Christine Proust, she is the head of the European Research Council project “Mathematical Sciences in the Ancient World” (SAW). Jacques Virbel, now retired, has served between 1975 and 1981 as vice-director of the Laboratoire d’Informatique pour les Sciences de l’Homme (Laboratory for Digital Humanities and Social Sciences). Between 1990 and 2005, he was a member of the Institut de Recherche en Informatique de Toulouse (Toulouse Institute of Computer Science Research). He has been the head of the multidisciplinary workshop “Text and Communication” (1989-2000) and of the “Cognitive Science Research Program” in Toulouse (1999-2002). Virbel has been active for forty years in information analysis and retrieval, linguistics, and pragmatics. His publications and other works focus on natural language processing and information management, text analysis and modeling in social sciences and the Humanities (archeology, history, architecture, literature, neuropsycholinguistics), text linguistics, speech acttheory, and visual semantics aspects of text architectures, application of text linguistics to text-to-speech engine for blind users of textual data, and design of psychology experiments using texts. Virbel is currently writing about an extension of speech act theory to written units larger than simple oral sentences (i.e.: texts).
