6 Conclusion
</SectionTitle>
    <Paragraph position="0"> This ongoing work has shown the importance of relative time lines in order to link events to one another. The identi cation of event elements and their normalisation will then form a basis for reasoning over these elements with regards to rst time-stamping of events and then temporally relating the events. The aim of many BioNLP studies is ultimately to reason over extracted events and, as such, the relative timing of these events is crucial. For example, if we know 1. tissue X is transformed into tissue Y at stage S and 2. molecule M is expressed in X at stage S-1, then it can be reasoned that event 2 has an impact on event 1. This reasoning can be made more successful if we know as much about the events as possible, not just that tissue Y is formed and molecule M is expressed.</Paragraph>
    <Paragraph position="1"> It has also been demonstrated that we not only need to look beyond the sentence level for temporal resolution but also beyond the article in order to replicate the reader's assumed level of background knowledge.</Paragraph>
