Figure 1 illustrates the interpretation of term-vectors: Topic specific terms (e. g. “program”, “software” and “Goethe”) point into the same direction as their fundamental topic which they are related to. In case a term combines two or more fundamental topics (due to visualisation limits this case is not shown in figure 1) it points into a combined direction of the two or more fundamental topics. Terms which are not topic specific at all (e. g. “is” or “the”) have a term-vector which has an angle near 45° towards all fundamental topics of the space R. The term-weight represents the relevance of a term
concerning its applicability to derive information about its relation to a topic in general. Term-weights are near to value one for topic specific terms and near to value zero for unspecific terms.
