The ESSAI corpus \ contains clinical trial protocols in French. They were mainly obtained from the \ National Cancer Institute The typical protocol consists of two parts: the \ summary of the trial, which indicates the purpose of the trial and the methods \ applied; and a detailed description of the trial with the inclusion and \ exclusion criteria. The CAS corpus contains clinical cases published in \ scientific literature and training material. They are published in different \ journals from French-speaking countries (France, Belgium, Switzerland, Canada, \ African countries, tropical countries) and are related to various medical \ specialties (cardiology, urology, oncology, obstetrics, pulmonology, \ gastro-enterology). The purpose of clinical cases is to describe clinical \ situations of patients. Hence, their content is close to the content of clinical \ narratives (description of diagnoses, treatments or procedures, evolution, \ family history, expected audience, etc.). In clinical cases, the negation is \ frequently used for describing the patient signs, symptoms, and diagnosis. \ Speculation is present as well but less frequently.
