In computer-aided architectural design, words are an underemployed
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.
