Text Mining-Based Patent Analysis of Bim Application in Construction

Abstract

As a data tool applicable to the full life-cycle of construction engineering and management, Building Information Modeling (BIM) has great potential for significantly increasing project productivity and performance. Awareness of BIM application hotspots and forecasting its trends can drive innovations in construction field. Using patents as data resources, this study develops an effective framework integrating the citation network analysis and the topic clustering technology to identify BIM application information and forecast its trends. This framework comprises three-step analysis:(1) quantitative characteristic analysis of patent outputs; (2) Social Network Analysis (SNA)-based co-occurrence network analysis; and (3) identification of BIM topics using a Latent Dirichlet Allocation (LDA). Finally, the case demonstrates the effectiveness of this framework contributing to promote technological development and innovation of BIM. The contributions of this study are threefold: (1) an innovative text mining-based framework for BIM patent analysis in construction is developed; (2) patents that have focused on identifying the application hotspots and development trend of BIM in accordance with our developed framework are reviewed; and (3) a signpost for technological development and innovation of BIM is provided.

Application of BIM Technology in Data Collection of Large-Scale Engineering Intelligent Construction

“…Sheng said that the idea of BIM began to take shape in the 1970s, and since then, BIM technology has been continuously developed in practical construction and theoretical applications and supplemented and defined in more detail [2]. Pan et al said that in the definition given by Wikipedia, it is pointed out that the purpose of BIM technology is to establish and manage the functions of engineering construction projects and the process of digitizing, visualizing, and visualizing physical characteristics [3]. Perera et al said that multiple forms of model information have become an important resource platform for sharing data and information in the process of project construction and are deeply embedded in the entire life cycle of the project (including project planning, design, construction, operation, and maintenance stages) [4].…”

Investigating the Key Hindering Factors and Mechanism of BIM Applications Based on Social Network Analysis

“…Out-degree refers to the number and association of the other nodes affected by this node. A high out-degree usually indicates that the node has more influence [71].…”

“…In this study, the social network analysis method was used to construct and analyze a social network model of the key hindering factors of BIM applications. The specific operation steps are as follows [71]:…”

Text mining and association rules-based analysis of 245 cement production accidents in a cement manufacturing plant

“…model is utilized to examine the interdependence between causal variables. To solve the problem of jumbled information in the investigation and recording of hidden dangers in subway construction, Pan et al (2021) researched and put forward an automatic analysis of hidden dangers recording framework, which includes Chinese word segmentation technology, TF-IDF (term frequency-inverse document frequency) algorithm, and…”
