Deriving technology intelligence from patents: Preposition-based semantic analysis
作者：
Highlights：
• A proposition-based semantic analysis to develop a patent network was proposed.
• The approach was applied to develop a technology-relation-technology network.
• Patents regarding an electric vehicle were adopted as an illustrative example.
• The relationships of technologies were defined using 13 meaningful prepositions.
• Five relationships were defined: inclusion, objective, effect, process, and likeness.
