2 The DELPH-IN collaboration
</SectionTitle>
    <Paragraph position="0"> DELPH-IN is a loose international collaboration of researchers developing open-source software components for language processing. These components include deep parsers, deep grammars for various natural languages, and tools for shallower processing. The HOG system (Callmeier et al., 2004) for the integration of shallow and deep linguistic processors (using a pipeline making use of XML plus XSLT transformations to pass data between processors) was developed during the Deep Thought project, as was a standard for the integration of semantic analyses produced by diverse components: RMRS (Copestake, 2003) allows underspecification of semantic analyses in such a way that the analysis produced by a shallow component may be considered an underspecification of a fuller semantic analysis produced by a deeper component. Other work (Waldron et al., 2006) has provided a representation of partial analyses at the level of tokenization/morphology - using a modification of MAF (Clement and de la Clergerie, 2005). Current work within the SciBorg project2 is investigating more fine-grained integration of shallow and deep processors.</Paragraph>
