ABSTRACT
Sufficient data and precise digital information are the main requirements for all processes within the BIM methodology. To enable an effective exchange and usage of data throughout the life cycle of a building, data catalogs and building codes provide centralized repositories using standardized definitions of building elements and properties. At present definitions for these elements and properties exist mostly in unstructured non-machine-readable form. This information needs to be transferred into structured data catalogs to be able to be used in the BIM process efficiently. To provide a structural basis to simplify exchange, interoperability, and portability ISO 23386 was conducted. This paper aims to conceptualize and implement a k-means clustering algorithm using GermaNet to support the creation of groups of properties hierarchies according to ISO 23386. Finally, the developed method is tested on different data catalogs and evaluated concerning its usability for the desired use case.
