The MON's Personal Events ontology provides a vocabulary for storing information about the main events of a person's life (e.g. Marriage, School attendance etc.). A <tt>PersonalEvent</tt> is defined as an event related to a person. Following the Neo-Davidsonian[1] event semantics, this class subsumes six event types: - <tt>Employment</tt> the fact of having a paid work; - <tt>Marriage</tt> the fact of being married with some one; - <tt>Attendance</tt> the fact of having attended a school; - <tt>PetOwnership</tt> the fact of owning a pet; - <tt>LivingInAPlace</tt> the fact of living in a place; - <tt>VisitingAPlace</tt> the fact of visiting a place. These six event types support the application for delivering the reminiscence therapy presented in [2]. Additional event types can be also gathered from Framester's Frames [3]. In fact, a frame is a stereotyped situation that could used to model information about events of a person's life. <b>References</b> [1] D. Davidson. The logical form of action sentences. In N.
