  Engineers often need to discover and learn designs from unfamiliar domains
for inspiration or other particular uses. However, the complexity of the
technical design descriptions and the unfamiliarity to the domain make it hard
for engineers to comprehend the function, behavior, and structure of a design.
To help engineers quickly understand a complex technical design description new
to them, one approach is to represent it as a network graph of the
design-related entities and their relations as an abstract summary of the
design. While graph or network visualizations are widely adopted in the
engineering design literature, the challenge remains in retrieving the design
entities and deriving their relations. In this paper, we propose a network
mapping method that is powered by Technology Semantic Network (TechNet).
Through a case study, we showcase how TechNet's unique characteristic of being
trained on a large technology-related data source advantages itself over
common-sense knowledge bases, such as WordNet and ConceptNet, for design
knowledge representation.
