6 Concluding remarks
</SectionTitle>
    <Paragraph position="0"> Current work on FCG includes the implementation of a head-driven, bidirectional chart-parsing algorithm. The basic idea is to use fillers of identifier positions to trigger bottom-up predictions. FCGs have the advantage that the search for topologically different, alternative projections of a head or other identifier, can be accomplished by a single active edge.</Paragraph>
    <Paragraph position="1"> On the other hand the category of an edge is often abstract, and has to be determined on the basis of category definitions and the content of the edges that combined to introduce it.</Paragraph>
    <Paragraph position="2"> Finally it should be stressed that while FCG is a variant of a LFG, the idea of regarding the schemas of traditional field grammars as structures of partim information can of course be exploited in any unification-based formalism.</Paragraph>
