3 Metadata based Navigation
</SectionTitle>
    <Paragraph position="0"> By tagging entity information and resolving cross document co-references for attorneys and judges, we were able to identify all the documents a particular attorney or judge appeared in. The RDF meta-data model goes a step further weaving together the relationships between attorneys, judges, rms, courts and the documents that reference them.</Paragraph>
    <Paragraph position="1"> With the metadata model it now becomes easier for the user to see all related information from any particular node. The combination of information extracted from documents with information from authority les, gives us a dynamic view of relationships in the content that can answer questions such as What other attorneys were mentioned in the same article? and Who else works at the same rm as this attorney? These relationships facilitate navigation between related entities. Figure 6 shows how the metadata model allows the user to navigate from one related node to the next. Not only are we able to tell the rm an attorney belongs to even if that wasn't speci cally mentioned in the text of the document, but we can also use the metadata model to shift our focus onto the rm node and immediately see a list of other attorneys related to that rm. Switching to any one of those nodes (attorneys) immediately shows us articles related to the next attorney. In a similar fashion we can move from judges to courts and articles and back.</Paragraph>
