5 Conclusion and Future Work

    <Paragraph position="0"> We developed an efficient retrieval engine for TFSs, ISTFS. The efficiency of ISTFS is achieved by calculating a unifiability checking table prior to retrieval and finding the best index paths dynamically.</Paragraph>
    <Paragraph position="1"> In future work, we are going to 1) minimize the size of the index tables, 2) develop a feature structure DBMS on a second storage, and 3) incorporate structure-sharing information into the index tables.</Paragraph>
