7 Conclusions
</SectionTitle>
    <Paragraph position="0"> We proposed term distillationfor cross-database retrieval. Using NTCIR-3 test collection, we evaluated this technique in patent retrieval and found a positive eect. We think cross-database retrieval can be applied to various settings including personalized retrieval, similar document retrieval and so on.</Paragraph>
    <Paragraph position="1"> For the future work, we hope to apply term distillation to cope with vocabulary gap problems in these new settings. In addition, we think term distillation can be used to present query terms to users in reasonable order in interactive retrieval systems.</Paragraph>
