8 Conclusion
</SectionTitle>
    <Paragraph position="0"> This article described a framework and an algorithm for solving references made to documents in meeting recordings by linking referring expressions to the document elements they denote. The implementation of the algorithm, together with test data (annotated meeting documents and transcripts) and an evaluation metric, show that the best results are obtained when combining anaphora tracking with a weighted lexical matching between RE plus right context, against title plus article contents.</Paragraph>
    <Paragraph position="1"> An extension of the present algorithm is under study, in which REs are processed differently according to their type: REs explicitly referring to an article ('the article', 'the section'), REs referring to positions ('the article at the bottom left'), REs referring to the entities of the contents, etc. These could be matched to various data categories from the document representations.</Paragraph>
    <Paragraph position="2"> Since printed documents and spoken interaction are two important modalities in communication, this article is also a step towards cross-modal applications. The reference-based alignment between transcripts and documents generates enriched transcripts, with explicit information about the contents and the timing of document mentions; conversely, it also helps document structuring. These in turn enhance browsing and searching capabilities for multimodal meeting processing and retrieval.</Paragraph>
