In this paper, we outline an approach for constructing clusters of related terms that may be used for deriving formal conceptual structures like taxonomies. In contrast to previous approaches in this direction, we take into account the fact that words can have several meanings and consider two alternative soft clustering techniques, namely Overlapping Pole-Based Clustering (PoBOC) and Clustering by Comittees (CBC) for this purpose. These soft clustering algorithms try to detect different contexts of the clustered words, resulting in possibly more than one cluster membership. We report on initial experiments conducted on textual data from the tourist domain.
