Abstract
In this paper we propose some improvements to the proposed ISO-TimeML standard for the semantic annotation of information about time and events. We argue that these improvements are called for, either in order to deal with suboptimal choices in the XML-based representation of annotation structures, or for resolving some of the difficulties that arise due to the impossibility to separate semantic phenomena relating to time and events, like temporal quantification, from their more general form. We indicate solutions for both types of cases.
