4 CONCLUSION
</SectionTitle>
    <Paragraph position="0"> In this paper, we have presented an object-based knowledge representation model that allows to extract and to represent knowledge in the knowledge base from discourse. This model can be used in the context of man-machine dialogue or for information retrieval.</Paragraph>
    <Paragraph position="1"> We have posed the problem of coherence as regarding the knowledge represented in the knowledge base, taking into account the apparent contradictions within discourse. The incoherence can be result fi:om a lot of phenomena but we restrict ourselves in this communication to incoherence stemming from negation. All the cases treated (among others) show that a surface negation does not always fit a deep negation and, in fact, seldom entails ~n incoherence. Consequently, the negation cart have art effect in object-based knowledge representation model such as to update properties of objects but it rztrely provobe ~n incoherence between the objects of discourse and the objects of knowledge base,</Paragraph>
