BIM-to-BRICK: Using graph modeling for IoT/BMS and spatial semantic data interoperability within digital data models of buildings
The holistic management of a building requires data from heterogeneous
sources such as building management systems (BMS), Internet-of-Things (IoT)
sensor networks, and building information models. Data interoperability is a
key component to eliminate silos of information, and using semantic web
technologies like the BRICK schema, an effort to standardize semantic
descriptions of the physical, logical, and virtual assets in buildings and the
relationships between them, is a suitable approach. However, current data
integration processes can involve significant manual interventions. This paper
presents a methodology to automatically collect, assemble, and integrate
information from a building information model to a knowledge graph. The
resulting application, called BIM-to-BRICK, is run on the SDE4 building located
in Singapore. BIM-to-BRICK generated a bidirectional link between a BIM model
of 932 instances and experimental data collected for 17 subjects into 458 BRICK
objects and 1219 relationships in 17 seconds. The automation of this approach
can be compared to traditional manual mapping of data types. This scientific
innovation incentivizes the convergence of disparate data types and structures
in built-environment applications
Realization of Semantic Atom Blog
Web blog is used as a collaborative platform to publish and share
information. The information accumulated in the blog intrinsically contains the
knowledge. The knowledge shared by the community of people has intangible value
proposition. The blog is viewed as a multimedia information resource available
on the Internet. In a blog, information in the form of text, image, audio and
video builds up exponentially. The multimedia information contained in an Atom
blog does not have the capability, which is required by the software processes
so that Atom blog content can be accessed, processed and reused over the
Internet. This shortcoming is addressed by exploring OWL knowledge modeling,
semantic annotation and semantic categorization techniques in an Atom blog
sphere. By adopting these techniques, futuristic Atom blogs can be created and
deployed over the Internet
