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/data-intensive approximations to a notional sub-type/supertype definition of the relationships between value and label cells.
