Determining whether a condition is historical or recent is important for accurate results in biomedicine. In this paper, we investigate four types of information found in clinical text that might be used to make this distinction. We conducted a descriptive, exploratory study us- ing annotation on clinical reports to determine whether this temporal information is useful for classifying conditions as historical or re- cent. Our initial results suggest that few of these feature values can be used to predict temporal classification.
