Comparison of multiple taxonomic hierarchies using TaxoNote

Morse, David R,; Ytow, Nozomi; Roberts, David McL. and Sato, Akira (2003). Comparison of multiple taxonomic hierarchies using TaxoNote. Technical Report 2003/17; Department of Computing, The Open University.



Recent work on modelling taxonomic names and the relationshipsbetween them has highlighted the need for capturing the multiple names and hierarchies that exist in taxonomic nomenclature. In this paper we describe TaxoNote Comparator, a tool for visualising and comparing multiple classification hierarchies. In order to align the hierarchies, the Comparator creates an integrated hierarchy containing all the taxa in the hierarchies to be compared, so that alignment of the hierarchies can be maintained. In addition, a table of assignments reports the taxonomic names that are common to all hierarchies and the differences between them, which facilitates structural comparisons between the hierarchies.
