6 Conclusions
</SectionTitle>
    <Paragraph position="0"> We presented two modules { Algas and Ogre { that build a dependency graph from a surface analysis. Algas uses information from a formalism called arrows properties. Nevertheless this formalism is independent from Algas input structures, that can be enriched with information that limits the relations to establish.</Paragraph>
    <Paragraph position="1"> In the future we want the user to be able to control the constraints over Algas output. That is, the user will have the option to chose if output may contain arrows crossing or not.</Paragraph>
    <Paragraph position="2"> For the moment the Susana-Algas-Ogre modules of the syntactic-semantic interface behave without problems in the domain of question interpretation. They apply successfully to an elicited corpus of questions produced by N portuguese speakers which were asked to produce them simulating e ective and natural questions.</Paragraph>
    <Paragraph position="3"> Our next step is to try to use them incrementally (A t-Mokhtar et al., 2002).</Paragraph>
    <Paragraph position="4"> Also, another improvement will be over arrow properties, as we want to organise them in a hierarchy.</Paragraph>
