Chatbots are commonly known nowadays as intelligent personal assistants which are designated to accomplish given tasks. The development of a good chatbot depends on the elements and features which then will be reflected in the performance and functionality of the application, user’s experience as well as satisfaction in order to complete their task. Two methodologies are applied in this paper, which are preliminary study and literature survey. The outcomes were reflected into the development of a new chatbot based on the attributes gained from the observation. The aim of this paper is to investigate the possible quality attributes from past researches and to develop a platform that will subsequently be used to build a quality chatbot for the tourism domain.

BACKGROUND: Aircraft maintenance and repair are critical tasks in the aviation industry for improved aircraft service and safety. Many articles and reports describe personnel factor and skill issues contribute to many aircraft incidents. Aircraft maintenance personnel needs to level up their skill set to match with task requirements in the setting of Industry Revolution 4.0. OBJECTIVE: The aim of this paper is to investigate document set that describe human errors and skill mismatch as a human factor in aircraft incidents and problems. It also discusses on the findings and management of the aircraft maintenance skill issues. METHODS: The study uses a document analytics tool to assess a set of online articles that discuss aircraft maintenance incidents and skill mismatch issues. The experiment is divided into four (4) modules: I collection of online articles and reports, (ii) document pre-processing, (iii) text analytics, and (iv) visualisation. RESULTS: The experiment’s results show that the majority of documents discuss aircraft maintenance, skill mismatch, and training gaps. CONCLUSION: We can conclude that the document dataset primarily discusses aircraft maintenance and skill set issues using the document analytics. Consequently, the management of aircraft maintenance workforce skill set issues by having initiatives for upskilling and reskilling Furthermore, firms should foster a culture of continuous learning and develop a mindset among their employees that allows them to adapt to new technologies and information in aircraft maintenance.

Requirement Elicitation is one of the challenging phases in the entire software development life cycle. It is the process of extracting and analyzing the requirements from customers to understand thoroughly of what system needs to be built. Despite all the advances in methodologies and practice approaches, extracting and establishing the right requirements are still part of the research debate. The objective of this paper is to compare the characteristics of two hybrid development approaches; Lean Six Sigma vs. Lean Agile. Most of the comparative studies done by most of the research compared within its relative knowledge such as; Lean vs. Six Sigma, Define-Measure-Analyze-Improve-Control vs. Design-For-Six-Sigma or Lean vs. Six Sigma vs Lean Six Sigma. Whereas in software industries, the comparative studies were focused on Lean vs. Agile, Agile vs. Waterfall, Lean vs. Kanban vs.Agile, which compared the project size, process cycle time, sequential or iterative process. The following parts of the study is to explore the differences and similarities in principles and practices. The study contributes significantly to the business analysts to systematically address the solutions and actions to ensure continuous improvement in producing quality software requirement.

B40 community school children experience many underprivileged lifestyles which impacted their academic performance. Through data trends and patterns, the education top management can observe the progress of academic performance and the lifestyle relationships of students in a school or nearby school. It can also help to identify the causes of progress or deterioration of the performance of B40 community students. Therefore, a data analytics framework is essential to help decision-makers to see and analyze the changing trends and patterns of academic progress in data and related lifestyles of B40 community students more effectively and accurately. The objective of this study is to design and develop association rules analysis to deduce the relevance of academic achievement and lifestyle among schoolchildren from the B40 family. The analysis framework is established in several stages that involve data collection and processing and transformation, then the design, application and evaluate of the association rules algorithms. The framework is expected to benefit students, teachers and Education Ministry. This study foresees whether educational programs and healthy lifestyle awareness can be designed specifically for the B40 children so as to improve their academic achievement as desired by the government.
