In computer aided architectural design words are an unemployed source of information. Through a series of case studies we deduced a design annotation data model. All entities in this model can be captured from the design draft, except one: the word-relation. Therefore a system was developed that generates word graphs using single words from the draft as input. The system searches for semantic relations between words and for new intermediate words that can connect two existing words. The system has filters that select only those graphs that are considered interesting by the designers. The envisioned applications of word graphs in the context of Computer Aided Architectural Design are to contribute to the architect's design and to enhance the fluency of the design. These expectations are met, but must be considered in relation to the architect's drafting behavior.
