Research on the integration of heterogeneous information resources in university management informatization based on data mining algorithms

AbstractAs far as the current higher education is concerned, the information system used in teaching and management is becoming more and more abundant, and the construction of its informatization is more and more rapid. However, the construction of university informatization project is too long, and there is no unified planning and other reasons, resulting in the difficulty of information and information management cannot be shared across departments. With the deepening of informationization and inaccurate information resources, how to use data mining technology to obtain valuable information is an important issue in the research of heterogeneous information in university management informationization. Based on the analysis of the information island problem in the informatization construction of colleges and universities, taking the student management work as a pilot, a heterogeneous information resource integration platform based on distributed query is proposed. Based on the platform, the information can be effectively applied globally. By analyzing its application in student information management, it shows that data mining is an effective technology to improve the management ability and scientific research level of colleges and universities in the construction of information technology.

Interoperability in construction – Mission impossible?

Throughout the history of human civilization, specialization and division of labour have been key factors of progress. They were made possible by the cooperation of ever-larger groups of people. Construction has been no exception. However, specialization leads to fragmentation - unless specialization is supported by approaches and technologies that enable people to work together and that systems are interoperable. When it comes to interoperability, the construction sector is often considered special, but it is not incomparable to other industries. Methodologically, this paper is based on the frameworks developed in the field of Enterprise Information Systems. It considers interoperability as a means to achieve a goal. Novel is the understanding that the ultimate goal is neither integration nor more efficient construction but rather the division of labour and specialization. A comparison of approaches to interoperability with those in other areas reveals some gaps. Research in construction information technology has focused on one type of interoperability - semantic interoperability - intending to achieve computer integrated construction. There are other types of interoperability - legal and organizational - and other levels of interoperability - federated and unified. These also deserve investigation. In the future, there will be a growing number of systems that would need to be made interoperable, especially in connection with the construction 4.0’s Internet of Things, sensors, intelligent systems, etc. Since interoperability problems are caused by the emerging specializations, the problems of interoperability will never go away. The industry will have to recognize that it will always operate in an environment where interoperability is challenged. While research will continue working towards making systems interoperable and integrated it would need also to give attention to exploring collaboration in environments that are only partially interoperable.

Screening patents of ICT in construction using deep learning and NLP techniques

PurposeThis study proposes an approach to solve the fundamental problem in using query-based methods (i.e. searching engines and patent retrieval tools) to screen patents of information and communication technology in construction (ICTC). The fundamental problem is that ICTC incorporates various techniques and thus cannot be simply represented by man-made queries. To investigate this concern, this study develops a binary classifier by utilizing deep learning and NLP techniques to automatically identify whether a patent is relevant to ICTC, thus accurately screening a corpus of ICTC patents.Design/methodology/approachThis study employs NLP techniques to convert the textual data of patents into numerical vectors. Then, a supervised deep learning model is developed to learn the relations between the input vectors and outputs.FindingsThe validation results indicate that (1) the proposed approach has a better performance in screening ICTC patents than traditional machine learning methods; (2) besides the United States Patent and Trademark Office (USPTO) that provides structured and well-written patents, the approach could also accurately screen patents form Derwent Innovations Index (DIX), in which patents are written in different genres.Practical implicationsThis study contributes a specific collection for ICTC patents, which is not provided by the patent offices.Social implicationsThe proposed approach contributes an alternative manner in gathering a corpus of patents for domains like ICTC that neither exists as a searchable classification in patent offices, nor is accurately represented by man-made queries.Originality/valueA deep learning model with two layers of neurons is developed to learn the non-linear relations between the input features and outputs providing better performance than traditional machine learning models. This study uses advanced NLP techniques lemmatization and part-of-speech POS to process textual data of ICTC patents. This study contributes specific collection for ICTC patents which is not provided by the patent offices.

Information and communication technologies (ICT) in construction and development of logistics systems

The higher and higher level of competitiveness of enterprises, the increasing expectations of customers or internalization of business are just a few examples of challenges that most of companies must face nowadays.

Review visual attention and spatial memory in building inspection: Toward a cognition-driven information system

With the increasing complexity of modern buildings, it is becoming more challenging for the professionals in the Architecture, Engineering, and Construction (AEC) industry to effectively digest complex engineering and design information and develop an accurate spatial memory that is critical to their daily tasks. As emerging visualization technologies, such as Virtual Reality, are considered as a promising solution, there is a pressing need to understand the mechanism by which different information visualization methods affect AEC task performance. Cognition literature has discovered a strong relationship between attention and memory development, but little has been done to understand how the visual attention patterns during the design documents review affect the effectiveness of spatial memory in AEC tasks. To fill the knowledge gap, this paper presents a human-subject experiment (n = 63) to test how spatial knowledge is acquired in a building inspection task and how the different visual attention patterns affect the development of spatial memory. Participants were asked to review the design information of a real building on campus. To trigger different attention patterns, they were randomly assigned to one of the three groups based on the forms of information given in the review session, including 2D, 3D, and VR groups. After a brief review session, participants were asked to go to the real building to identify discrepancies (based on memory) that were intentionally inserted by the authors. The inspection performance was used to evaluate the spatial memory development. The results indicate that in general there is a positive relationship between test subjects’ visual attention (fixation time) and spatial memory, but the increasing rate varies across the three groups, suggesting that visual context plays a critical role in the development efficiency of spatial memory. The findings also indicate that the visual attention – spatial memory relationship may be mediated by the use of different spatial knowledge acquisition strategies. This study is expected to contribute to the construction information technology literature by setting the cornerstone of a cognition-driven information system that tailors into the spatial cognitive process of AEC professionals.

The use of information technology in the management of construction projects has become a decisive factor for the successful completion of projects, taking into account time, quality and financial costs. There are challenges in visualizing the planning process and integrating information between stakeholders. The paper considers some aspects of the development trend of information technology in construction. The element base, including the risks arising during the design and construction, associated with the direct use of computer and mathematical models of the object in the design is considered. The generated information models will provide basic information for the participants in the design process, which ultimately will be the basis of the element base of an effective tool for ensuring project life cycle management. The following methods were used: system analysis, logical-mathematical modelling, systems theory, economic-visual modelling, research methods of operations, economic and mathematical methods. A basic block diagram of 4D modelling is presented to minimize the occurrence of risks during design. The model allows considering the possibility of assessing the duration of the project, the level of labour productivity, as well as visualizing the construction process. The presented analysis indicates the importance of using 4D modelling in relation to the life cycle of the object in order to prevent the possibility of construction risks.
