From knowledge based software engineering to knowware based software engineering

The first part of this paper reviews our efforts on knowledge-based software engineering, namely PROMIS, started from 1990s. The key point of PROMIS is to generate applications automatically based on domain knowledge as well as software knowledge. That is featured by separating the development of domain knowledge from the development of software. But in PROMIS, we did not find an appropriate representation for the domain knowledge. Fortunately, in our recent work, we found such a carrier for knowledge modules, i.e. knowware. Knowware is a commercialized form of domain knowledge. This paper briefly introduces the basic definitions of knowware, knowledge middleware and knowware engineering. Three life circle models of knowware engineering and the design of corresponding knowware implementations are given. Finally we discuss application system automatic generation and domain knowledge modeling on the J2EE platform, which combines the techniques of PROMIS, knowware and J2EE, and the development and deployment framework, i.e. PROMIS/KW＊＊.

Blockchain as a Service (BCaaS): A Value Modeling Approach in the Education Business Model

The adoption of Blockchain has caused the organization to rethink how it operates and adds value to its current processes. Some scholars refer to Blockchain as the Black Swan of the 21st century, which will have a greater impact than the introduction of the Internet. Currently, there is little discussion about Blockchain technology and the value model approach and how organizations can close the gap between strategy and operational planning to successfully implement this technology in organizations. This paper explores the relationship and implications of Blockchain technology in relation to the value chain model in education. This paper proposes a value modeling approach for implementing Blockchain in the education sector and demonstrates how a solution works in practice. The novelty of the research will be from both theoretical and practical perspectives. The study will appraise enhancement that can be made within the existing literature on Blockchain and the value chain model, and how the alignment of the two concepts can be used to improve the use of the current value chain model in the education sector.

Computing a ground appropriateness index for route selection in permafrost regions

The reasonable calculation of ground appropriateness index in permafrost region is the precondition of highway route design in permafrost region. The theory of knowledge base and fuzzy mathematics are applied, and the damage effect of permafrost is considered in the paper. Based on the idea of protecting permafrost the calculation method of ground appro- priateness index is put forward. Firstly, based on the actual environment conditions, the paper determines the factors affecting the road layout in permafrost areas by qualitative and quantitative analysis, including the annual slope, the average annual ground temperature of permafrost, the amount of ice in frozen soil, and the interference engineering. Secondly, based on the knowledge base theory and the use of Delphi method, the paper establishes the knowledge base, the rule base of the permafrost region and inference mechanism. The method of selecting the road in permafrost region is completed and realized by using the software platform. Thirdly, taking the Tuotuo River to Kaixin Mountain section of permafrost region as an example, the application of the method is studied by using an ArcGIS platform. Results show that the route plan determined by the method of selecting the road in perma-frost region can avoid the high temperature and high ice content area, conform the terrain changes and evade the heat disturbance among the existing projects. A reasonable route plan can be achieved, and it can provide the basis for the next engineering construction.
