On the application of the Two-Factor Theory to online employer reviews
Journal of Data, Information and Management - Tập 4 - Trang 1-23 - 2021
Philipp Koncar, Tiago Santos, Markus Strohmaier, Denis Helic
Monitoring hygiene and motivation factors from Herzberg’s Two-Factor Theory is a popular way of understanding the influential aspects for employee satisfaction and motivation. The increased availability of employee feedback comprised in online employer reviews yields a promising data source to learn more about these influential factors and the theory itself. However, the application of the Two-Fac...... hiện toàn bộ
imc-precip-iso: open monthly stable isotope data of precipitation over the Indonesian Maritime Continent
Journal of Data, Information and Management - - 2024
Rusmawan Suwarman, Sandy Herho, Halda Belgaman, Kimpei Ichiyanagi, Takayuki Uesugi, Dasapta Irawan, Imam Yosa, Arika Utami, Sonny Prayogo, Edvin Aldrian
Stable isotopes, δ2H, δ18O, and d-excess, are valuable tools as natural tracers of diffusion processes and phase changes in the global hydroclimatological cycle. The Indonesian Maritime Continent (IMC) is an archipelago area surrounded by very warm waters which induce convective activities as the primary heat source driving global atmospheric circulation. Given the central role of IMC in this hydr...... hiện toàn bộ
AI in operations management: applications, challenges and opportunities
Journal of Data, Information and Management - Tập 2 - Trang 67-74 - 2020
Ali K. Dogru, Burcu B. Keskin
We have witnessed unparalleled progress in artificial intelligence (AI) and machine learning (ML) applications in the last two decades. The AI technologies have accelerated advancements in robotics and automation, which have significant implications on almost every aspect of businesses, and especially supply chain operations. Supply chains have widely adopted smart technologies that enable real-ti...... hiện toàn bộ
An inconsistency index of interval additive reciprocal matrices with application to group decision making
Journal of Data, Information and Management - Tập 2 - Trang 201-213 - 2020
Fang Liu, Qin Yu, Mao-Jie Huang, Dan A. Ralescu
Inconsistency measure and aggregation of decision information are two important issues in group decision making. In this study, interval additive reciprocal matrices are used to express the opinions of decision makers within the framework of fuzzy analytic hierarchy process (FAHP). Some existing consistency indexes of interval additive reciprocal matrices are reviewed and the existing shortcomings...... hiện toàn bộ
A risk-averse multi-item inventory problem with uncertain demand
Journal of Data, Information and Management - Tập 1 - Trang 77-90 - 2019
Yanan Li, Ying Liu
The observed values of demands in real-life inventory problems are sometimes imprecise due to the lack of information and historical data, thus a growing research is committed to study the properties of risk measures in fuzzy inventory optimization problems. In this paper, a risk-averse fuzzy optimization method is adopted for the multi-item inventory problem, in which the demands are described by...... hiện toàn bộ

Hệ thống tổ chức, thu thập và trình bày thông tin tình báo nguồn mở Dịch bởi AI
Journal of Data, Information and Management - Tập 4 - Trang 107-117 - 2022
Saiful Khan, David Wallom
Thông tin tình báo nguồn mở là một lĩnh vực đang phát triển nhanh chóng trong ngành an ninh và tình báo, liên quan đến việc thu thập dữ liệu mở từ các nguồn trên internet, biến dữ liệu đó thành tình báo có thể hành động, và tái sử dụng khi có thể và phù hợp. Trong quá trình tạo ra hoặc xử lý dữ liệu đầu vào thô, việc ghi lại và quản lý thông tin nguồn gốc tương ứng, ví dụ như quy trình làm việc, t...... hiện toàn bộ

Multi-task learning in under-resourced Dravidian languages
Journal of Data, Information and Management - Tập 4 - Trang 137-165 - 2022
Adeep Hande, Siddhanth U. Hegde, Bharathi Raja Chakravarthi
It is challenging to obtain extensive annotated data for under-resourced languages, so we investigate whether it is beneficial to train models using multi-task learning. Sentiment analysis and offensive language identification share similar discourse properties. The selection of these tasks is motivated by the lack of large labelled data for user-generated code-mixed datasets. This paper works wit...... hiện toàn bộ
Uncertain barrier American options pricing problems based on floating interest rate
Journal of Data, Information and Management - Tập 5 - Trang 255-265 - 2023
Lifen Jia, Jiarui Jiang, Fengjia Guo
A Knock-in option is a path-dependent barrier option whose payoff depends on whether the value of the underlying asset reaches a specific threshold. In this paper, we establish an uncertain stock model with a floating interest rate and provide the pricing formulas for American knock-in options. Besides, we present parameter estimation for the uncertain stock model and conduct an uncertain hypothes...... hiện toàn bộ
Big data for sustainable agri‐food supply chains: a review and future research perspectives
Journal of Data, Information and Management - Tập 3 - Trang 167-182 - 2021
Abderahman Rejeb, Karim Rejeb, Suhaiza Zailani
Research on agri-food supply chains (AFSCs) has attracted significant attention in recent years due to the challenges associated with sustainably feeding the global population. The purpose of this study is to review the potentials of big data for sustainable AFSCs. One hundred twenty-eight (128) journal articles were selected to identify how big data can contribute to the sustainable development o...... hiện toàn bộ
