6 Conclusions
</SectionTitle>
    <Paragraph position="0"> Itseemsthatthemajorityofeventsarenotfully described within a single sentence, at least for one of the most commonly used IE evaluation sets. Only around 40% of events in the original MUC data set were fully expressed within the Soderlanddataset. Itwasalsofoundthatthere is a wide variation between difierent event flelds and some information may be more di-cult to extract from text when the possibility of events being described across multiple sentences is not considered. This observation should be borne in mind when deciding which approach to use for a particular IE task and should be used to put the results reported for IE systems which extract from a single sentence into context.</Paragraph>
