||The Formal concept analysis goes back to the 1940s and is advanced by Rudolf Wille in the eighties. Based on the algebraic lattice theory so-called concept lattices will be used for visualisation of hierarchical structures in a line diagram. The method needs as input a context consisting of sets of objects and attributes and a binary relation between these objects and attributes. In a concept lattice quantitative and qualitative data can be combined and relations between the objects as well as between the attributes can be analysed. Therefore concept lattices are suitable for analysing the results of surveys. The respondents and their answer patterns constitute the context. Precondition is a hierarchical structure of the answers (e.g. ordinal ordered data). In this presentation will be demonstrated how to use the line graph of the concept lattice for analysing complex questions of tourist surveys. As an example the main activities of about 600 tourists and daily visitors in the Lake Neusiedl Region are analysed. With the procedure of Formal Concept Analysis the different answer patterns of respondents are arranged as nodes in a line diagram. This diagram is constructed by means of two partial concept lattices that will be integrated later. The interpretation of the line graph will start at the biggest nodes, consider the whole structure of the graph and include additional attributes in order to describe groups of tourists with the same activity pattern.
