Retrieval of plane geometry resource database based on dynamic geometry
Guo Yuan-gang · Journal of Computer Applications · 2008
It is not satisfactory to retrieve similar geometry propositions in geometry resource databases in a traditional way. For plane geometry resource databases based on dynamic geometry, this paper provided a similar retrieval method using geometry characteristic information. Geometry characteristic information quantifies various geometry elements of a geometry proposition and can be extracted from drawing instruction sequences, this retrieval method can properly find out similar geometry propositions.
