A new method has been experimented in order to identify more easily allergenic spores and pollen grains from Northern Europe described in the Atlas of Nilsson et al. (1977). It is a knowledge base system named XPER. This system based upon an automatic elaboration of a data matrix, includes for this contribution, 74 individuals (or taxa, objects) 40 variables (or characters, features) and 199 modalities (or character states). It is an on-line program type of identification (monothetic and multi-access key) working on several types of microcomputers. Four main subunits are available in this program (1) an editor to create, consult and modify the data arrangement of either taxa or characters or states; (2) a determiner to identify an unknown taxon by a step-by-step identification with possible return and several options; (3) a reorganizer to modify drastically the data and to connect several bases and (4) a printer to give as options, either only on the video display unit or simultaneously on paper listing: list of taxa, characters, states, data-matrix and complete descriptions of each taxon. |
