Abstract
We describe a prototype system for assigning table cells to their proper place in the table's logical (relational) structure, based on a simple model of table structure combined with a number of measures of cohesion between cell contents. Preliminary results suggest that very simple string-based cohesion measures are not sufficient for the extraction of relational information, and that future work should pursue the aim of more knowledge/dataintensive approximations to a notional subtype /supertype definition of the relationships between value and label cells. 1 Introduction Real technical documents are full of text in tabular and other complex layout formats. Most representations of tabular data are layout or geometrybased: in sgml, in particular, Marcy Thompson notes "table markup contains a great deal of information about what a table looks like. . . but very little about how the table relates the entries. . . . [This] prevents me from doing automated context-based data retrieval or...
