One of the main aims of European ethnology in the second half of the 20th century was to create the ethnographical atlases of various nations in Europe. The basic purpose of the cartographical elaboration of the regional variants of certain cultural elements of the given nation in a certain system and that of collecting them into atlases was to create a database on which investigations could be carried out to define the territorial structure of the given folk culture. The easiest way to define this territorial pattern is the computer elaboration of the database, which means the digitalization and the cluster analysis of the data made by computer. On the methods and on the possibilities of the computer elaboration of the Atlas of Hungarian Folk Culture (AHFC) a paper was held by the author at the 11th Conference of the SIEF’s International European Network (Workgroup) on Ethnocartography in Poland (Borsos 2000). At the 12th conference in Slovakia the author talked about the first results of the cluster-analysis (Borsos 2000/2001).In the last decade the computer programs for the digital version of the AHFC have been developed and the digital version has been extended with supplementary maps as well. As in the digital version we can find not simply scanned pictures of the original sheets but the basic structure of the atlas (base-map, collecting points) is also available, it is not only possible but fairly easy to add new (virtual) sheets to the atlas. So the Atlas has been supplemented with maps elaborating some of the statistical data (demographic and agricultural) of the period between 1900–1910, which is the time interval represented by the cultural data of the atlas. This virtual 10th volume of the atlas contains ‘sheets’ about important information on the cultural picture of the settlements shown and of their cultural environment. The new volume can also help to draw a more accurate map about cultural regions. Another type of supplementary maps can be seen in the virtual 11th volume showing the regional distribution of the territory inhabited by Hungarians regarding cultural and non-cultural aspects. The last section of the distributional maps shows the regional structure of the Hungarian folk culture based on the computer elaborated data of the first 9 volumes, as well as the synthetic regional structure based on the comparison of the computer-drawn picture with three other sources: the statistical investigations of the database, the maps of the two virtual volumes and the scientific literature.

First the author summarizes the attempts of defining the regions of Hungarian folk culture and he concludes that the next step in this kind of investigation must be a certain definition based on as many cultural elements as possible. He intends to do it by using the database of the Atlas of Hungarian Folk Culture and computer methods. He investigates the opportunity and the problems of the transformation of the data of the Atlas into a computer database, he presents the problems to be solved and some possible solutions. He concludes that for various reasons only a limited number of the cultural phenomena mapped in the atlas are suitable for computer analysis. He summarizes the methodological background of the correlation and cluster analysis to be used. He emphasizes that due to the special character of mapping the inconsistencies and the mixing of different points of view in the Atlas, and to the character of the computer analysis that is mechanical and not elaborate enough, this kind of definition of the cultural re-gions of the Hungarian-speaking areas cannot replace the previous definition of regions but it can offer a good frame of reference to define the regions more precisely.
