Semantic web technologies in AEC industry: A literature overview

E‐maintenance platform design for public infrastructure maintenance based on IFC ontology and Semantic Web services

“…20 Furthermore, it is hard to define a model to satisfy the particular needs of various experts involved because the model is not allowed to extract partially. 22 As the most widely used data exchange standard for BIM, IFC developed by building SMART, which provides the commonly shared concepts, attributes, and relationships of BIM resources, 20 has been widely supported by the market-leading BIM software vendors in the AEC industry. 22 As the most widely used data exchange standard for BIM, IFC developed by building SMART, which provides the commonly shared concepts, attributes, and relationships of BIM resources, 20 has been widely supported by the market-leading BIM software vendors in the AEC industry.…”

“…22 The application of semantic technologies transforms the Web into a semantic network that is globally interconnected. The creation of these links between data on the Web enables people and machine to explore them.…”

“…19 In order to overcome these problems, industry domains and software developers have been trying to change the ways to define, tailor, and manage the semantics of product models, which makes semantics of a building a research hotspot. 22 As the most widely used data exchange standard for BIM, IFC developed by building SMART, which provides the commonly shared concepts, attributes, and relationships of BIM resources, 20 has been widely supported by the market-leading BIM software vendors in the AEC industry. 23 The IFC schema is based on a set of concepts, such as classes, attributes, relationships, property sets, and quantity definitions, to describe information of building models to be exchanged between different software applications so that BIM data can be extracted from proprietary software and be exchanged with other applications.…”

“…Pauwels et al conclude three main added value features brought by Semantic Web technologies, which are information exchange, data integration and complex search queries across several data sources, and construction document information management. 22 The application of semantic technologies transforms the Web into a semantic network that is globally interconnected. Semantic Web technologies enable an explicit representation of the meanings of the information on the Web by means of ontologies.…”

Comparison between traditional and digital preliminary cost-estimating approaches

“…Furthermore, the evaluation of the information contained in the virtual objects that constitute the model generated using BIM Authoring tools must consider also the information that are linked to the objects from different sources (e.g., databases, devices, etc.) [18][19][20]. Thus, the implementation of a digital system that is able to provide cost evaluation in a preliminary phase requires the definition of a structured cost library that can be defined with different levels of integration, starting from element cost types and reaching the introduction of resources and activities.…”
