... Gajzler proposed a scheme to support the technological decisions through a text mining analysis, that is able to provide a quantitative representation of text documents to provide a tree diagram that shows that it is feasible to perform such analysis to result in an accurate statistical analysis. He also proposed another classification mechanism that is capable of measuring how the location affects the selection criteria of apartment sales [26]. Bilal and Oyedele developed a benchmarking system which is capable to evaluate the tender profitability using deep learning and text mining techniques combined with Big Data processing tools, the model generated a list of seventeen key performance indicators (KPIs) which wraps the different aspects related to each project that affect its profitability [27]. ...
Complexity of the construction projects vary by the domain and type of the project. Due to the interaction between different disciplines and parties, Energy and Petroleum Projects (EPP) are considered among the most complex. This complexity produces a dense network of interrelated documents which are produced to cover the various aspects and details of the project. Analyzing this network which is composed of unstructured data is required to gain insights from old data, this task traditionally requires experience, knowledge, and awareness about the existence of the required data. Accordingly, a key asset of any company is the knowledge accumulated over the time from various projects. This research proposes a framework that enables salvaging traditional archives and include its data in searchable databases to increase the efficiency of archiving such accumulated data without affecting the normal workflow of companies, and hence decrease the manhours expenditure and reduce the time of archiving while not affecting the accuracy of the outcome. Due to the large diversity of the EPP projects, the research focuses on five main commodities which are selected based on the frequency of their existence in projects in addition to their monetary value as the main data to be stored which are Tanks, Air Coolers, Pumps, Generators and Distributed Control Systems (DCS). The key attributes of each commodity are identified based on technical questionnaires with technical specialists to act as the basis for building the proposed framework. The proposed framework integrates four modules to provide a complete solution to the problem, by implementing data mining techniques while harnessing the power of big data analytics tools to transform the existent unstructured data into structured data in the form of smart archives which can then be used to support ongoing business processes.
... Also, the record of events -faults, failures may not be a categorical source of information about the condition of the building, at best it is a prognostic. A building book is a much better source of information about a building, which is an element required by the applicable law in the country [13,14,15,17]. The A protocol prepared in this way has the character of a qualitative description, where on its basis the engineer controlling the building summarizes and evaluates it through qualitative values according to the adopted scale, e.g. ...
By analyzing the individual stages of the building's life cycle, it can be easily concluded that the building's exploitation process is the longest and at the same time it is the justification for the construction project related to the construction of this building. In the course of the building's exploitation, various phenomena occur that affect its condition and thus the possibility of unlimited use. These are natural phenomena, as well as phenomena derived from external influences, which often lead to deterioration of the building's condition, or even its degradation. In response to these phenomena, maintenance, renovation and modernization activities are undertaken. Technical management is related to the identification of these phenomena, programming of adequate measures and their implementation. The conducted analysis of the results of the survey in the group of property managers allows to state categorically that the process of technical management is relatively little supported by IT tools and is still based on individual analysis and often intuitive actions. The article presents the possibilities of applying an innovative approach in the acquisition and collection of information about the technical condition of buildings, indicating the legitimacy of standardizing information forms and using them in building a database of cases of the CBR (case based reasoning) inference system. © 2021.

... There have been genuine and wrong approaches to the demand for more buildings in Nigeria in order to meet the population surge in Nigeria [3]. The wrong approach, which include but not limited to the use of sand Crete blocks as beams, as shear and load bearing walls, sub-standard materials such as reinforcement, cement and also poor concrete, has contributed greatly to the collapse of many building in Nigeria [4]. ...
Building failure or collapse happens both in the developed and developing countries but the rate of occurrence in the developing country such as Nigeria is quite alarming and therefore call concern. The menace of building collapse in Nigeria is very alarming and appalling. Building collapse in Nigeria has become the norms they are easily swept under the carpet whenever it occurs. It is rather unfortunate that both human and economic loss we record each time there is a failure or building collapse is rather humongous. There is also a lot of blame game among professional stakeholders in the industry once failure or collapse of building occur and unfortunately, there is no proper scientific investigation in most developing countries such as Nigeria to ascertain the cause of failure or collapse as the case may be in order to avoid any future occurrence. In the cause of this review, it was discovered that building materials such as reinforcing steel, cement, sand, granite, sandcrete blocks and concrete play huge important role in either the collapse or stability of buildings in Nigeria. The roles of these materials are so vital that they contribute immensely to the collapse of buildings. It was concluded that 10-25% of buildings that collapse in Nigeria are as a result of the use of poor quality building materials. The review has extensively dealt with building collapse in relation with the role of building materials during construction.
... Before now, concrete was produced of three or four materials namely; cement, aggregate sand and water, but presently durable concretes combine six or more construction materials. Various researches have been done on mineral admixture [13][14][15][16][17][18][19][20][21]. Minimizing micro cracks in concrete can be achieved through mixing the concrete with mineral admixtures either in the batching plant or in the bond plant [20], improves the service life of concrete structure in a cost-effective manner. ...
This study was carried out to review different types of available innovative construction materials. It was found that advancement in nanotechnology, use of mineral admixture, glass and plastic, biological materials, wood and other construction materials have contributed significantly to the growth of discovery and production of innovative construction materials. The implementation of some innovative construction materials, meets the requirements for sustainability, durability, reliability, safety, cost reduction, increasing quality, better mechanical and physical characteristics, flexibility in extreme conditions and locations, simple assembly and environmentally friendly. Construction materials used to carry out project consumed about 40% of the entire cost of the project in the construction industry. The success stories were recorded in the area of turning industrial and agricultural wastes to wealth. This reviewed paper will enrich the database for innovative materials entering the construction industry.
... Gajzler [42] shows a good and condensed view of the DIKW pyramid, which evolved over many years, as can be seen in figure 2.3. "The DIKW pyramid, also known variously as the DIKW hierarchy, wisdom hierarchy, knowledge hierarchy, information hierarchy, and the data pyramid, refers loosely to a class of models for representing purported structural and/or functional relationships between data, information, knowledge, and wisdom. ...

Large and complex systems are used in every field of industry and research. Most of these systems can be classified as knowledge processing systems or subgroups of these. We investigate how someone can trust such systems and their outputs when only knowing how trustable the used inputs and sources are and how the system is working.
After broad structured investigations the conclusion was that there exist some ways and methods in a larger context, but there is a strong need for embedding trust in particular into the work with knowledge processing systems, so the first contribution of this thesis is a sound and comparing literature review on knowledge processing and trust and their related research fields.
One hurdle in this is also the multidisciplinary application of the term "Trust" and finding a distinguished handling and definition for applying trust in a technical domain.
The second contribution of this thesis is the proposing of a definition of the "Trust Model" terminology in the context of knowledge processing and the investigation of suitable trust models. These models are the "Binary Trust Model", the "Probabilistic Trust Model", the "Opinion-Space Trust Model", and our self developed "Weighted Arithmetic Mean Trust Model" which suits in particular for the application in knowledge processing systems.
Furthermore as a third contribution, we discuss these models for measurement, application, and ways of how to work with trust in knowledge processing systems. We focus on the possibilities of how to propagate trust through (multiple calculation steps executing) knowledge processing systems and evaluate and compare the investigated and developed trust models on several scenarios. We are convinced that the field of knowledge processing could highly benefit by using trust.
With our research work and the evaluation of the models we are one step closer to our initial motivation of finding suitable ways for using trust in knowledge processing.

The importance of issues related to digitization, integrated activities (from integrated management to the integrated BIM), and partly augmented reality were highlighted. An attempt to synthesize new instruments in Construction Management has been presented.
... The American Institute of Architects (AIA) has created a new type of contract, used for the implementation (design) of construction projects, called the Integrated Project Delivery (IPD), [22]. Integrated design is an iterative and interactive process, a way of implementing the entire investment process, which, in a rational (almost optimal, [5,[23][24][25][26][27]) manner, in terms of cooperation of the project team-which includes the architect, the industry, the investor, the contractor and the user-allows creation of a balanced object from the viewpoint of construction and operating costs. ...
This article presents the architect's attitude towards the paradigms of sustainable development. The place and role of the architect in the implementation of the multidimensional processes of sustainable design are presented. Basic dilemmas and antinomies are presented. The analysis of architects' attitudes towards these problems is performed in various contexts, examining the architect's awareness and his/her environment in view of changes under way. The article draws attention to the status of knowledge, changes in design paradigms, legislative and organizational requirements. The importance of architectural culture level, the need for training and ways to support the implementation of new design paradigms through integrated activities are indicated. The research results, regarding public awareness of architecture and sustainable development, are illustrated, with examples from Poland.
... In order to attract investments and to use them purposefully, public authorities must have economic skills in state or district management. This may be achieved by relying on the experience of countries with strong economies and evaluating the future positive or negative effects of capital expansion directions, applying the latest concepts of sustainable development and multicriteria methods for the search and selection of alternative solutions [15][16][17]. Therefore, to identify opportunities of increasing investment attractiveness and to purposefully direct investment flows to the problematic business branches and/or problematic areas, it is necessary to develop a purposeful investment absorption strategy and to minimise potential risk factors (Fig. 1). ...
The region's macro environment analysis identifies the measures that would improve the investment environment in the region and help to create an effective direct domestic and foreign investment promotion system. Based on the findings of the integrated analysis, in the decision-making stage the investment direction is selected, the implementation of which will allow achieving the stated goal. The alternatives for the implementation of the investment direction are formed. Alternatives are described using the efficiency criteria and are assessed using MCDM1 multi-criteria methods. The article presents the creation of the theoretical model of determination of the investment strategy in the context of sustainable development. The study includes an integrated regional analysis using Vilnius district as an example.
... Construction projects are unique and temporary, which means that construction project teams are also temporary and consist in multidisciplinary teams. During these projects it is valuable to collect information about events, consequences and the steps taken together with their effectiveness 25 . It is important to collect all available information and use it in subsequent projects. ...
In modern economic society, organizations’ competitiveness relies heavily on their ability to leverage and manage knowledge rather than in physical assets, some authors refer even though the concepts of knowledge management (KM) are being well implemented in the industrial sector, the construction segment, however, appears to have some difficulties in adopting the practices and strategies offered by KM. It is known that the construction sector (CS) is experiencing a time of instability and recession, and one of the causes of this may involve the lack of adaptation to knowledge era. Therefore, this paper, based on literature review, gives an overview of inhibitor and the facilitator factors of knowledge sharing (KS) with the objective to answer two questions: which of the KS inhibitors and facilitators characterize the CS? has the CS its specifics KS inhibitors and facilitators? It’s presented a framework in order to verify the existence of exclusive factors of the sector. At this point it is possible to suggest that CS has mainly organizational factors as inhibitors and the facilitator’s factors are almost individual. The facilitating factors might be the consequence of an effective and successful KS strategy and can be seen as guidelines to improve the construction industry organizational performance.
Purpose
Knowledge- and communication-intensive domains still long for a better support of creativity that considers legal requirements, compliance rules and administrative tasks as well, because current systems focus either on knowledge representation or business process management. The purpose of this paper is to discuss our model of integrated knowledge and business process representation and its presentation to users.
Design/methodology/approach
The authors follow a design science approach in the environment of patent prosecution, which is characterized by a highly standardized, legally prescribed process and individual knowledge study. Thus, the research is based on knowledge study, BPM, graph-based knowledge representation and user interface design. The authors iteratively designed and built a model and a prototype. To evaluate the approach, the authors used analytical proof of concept, real-world test scenarios and case studies in real-world settings, where the authors conducted observations and open interviews.
Findings
The authors designed a model and implemented a prototype for evolving and storing static and dynamic aspects of knowledge. The proposed solution leverages the flexibility of a graph-based model to enable open and not only continuously developing user-centered processes but also pre-defined ones. The authors further propose a user interface concept which supports users to benefit from the richness of the model but provides sufficient guidance.
Originality/value
The balanced integration of the data and task perspectives distinguishes the model significantly from other approaches such as BPM or knowledge graphs. The authors further provide a sophisticated user interface design, which allows the users to effectively and efficiently use the graph-based knowledge representation in their daily study.
