[Poster presentation] 

Floras hold vast resources of botanical data, locked in multiple overlapping natural language texts. MultiFlora aims to provide proof  of concept that by applying "Information Extraction" techniques to parallel descriptions of a taxon and correlating the resulting partial datasets, we can derive a usefully complete and accurate description.

Initial hand analysis has produced three-dimensional data matrices (Flora x characters x species ) for five species of  Ranunculus, across six Floras. Variations in terminology, and in use of mean values or ranges, are common but genuine disagreements are rare.  The GATE system (University of Sheffield) will be used to provide automatic IE, and correlation heuristics will be implemented.
