Abstract
This paper aims to apply the clustering analysis algorithm to analyze and classify the pattern of spatial topology of floor plans within a case library named “Open Case Study (OCS)”. Based on the results, this paper proposes a visual interface named “Topology Pattern Mining (TPM)” to present and rank search results in response to users’ queries. The purpose of TPM is to extend the capacity of OCS for representing the implicit knowledge of spatial topology. TPM can retrieve and classify design patterns of spatial topology, which thereby helps designers as well as participants to select appropriate proposals.
