APPLICATION OF FORMAL CONCEPT ANALYSIS TO EVALUATE ENVIRONMENTAL DATABASES

The application of Hasse diagrams for comparative evaluation may be us eful. One drawback, however, is that sometimes the Hasse diagrams cons ists of several parts, which are not connected. In such cases the inte rpretation becomes troublesome or even impossible. With the example of environmental databases on CD-ROM it is shown how lattice theory help s in such cases. It can be exemplified that a specific data structure leads to the disintegration. (C) 1997 Elsevier Science Ltd.
