Multi-source Education Knowledge Graph Construction and Fusion for College Curricula

The field of education has undergone a significant transformation due to the rapid advancements in Artificial Intelligence (AI). Among the various AI technologies, Knowledge Graphs (KGs) using Natural Language Processing (NLP) have emerged as powerful visualization tools for integrating multifaceted information. In the context of university education, the availability of numerous specialized courses and complicated learning resources often leads to inferior learning outcomes for students. In this paper, we propose an automated framework for knowledge extraction, visual KG construction, and graph fusion, tailored for the major of Electronic Information. Furthermore, we perform data analysis to investigate the correlation degree and relationship between courses, rank hot knowledge concepts, and explore the intersection of courses. Our objective is to enhance the learning efficiency of students and to explore new educational paradigms enabled by AI. The proposed framework is expected to enable students to better understand and appreciate the intricacies of their field of study by providing them with a comprehensive understanding of the relationships between the various concepts and courses.Comment: accepted by ICALT202

A study of senior-friendly transportation services in Beijing

Thesis (Master's)--University of Washington, 2020With the increasing population of the elders in China, many social challenges arise. To make travel easier for the elderly, new technology can be used to increase transportation services. This thesis will use successful cases around the world as examples and conclude with useful planning and design approaches to use in Beijing. Based on the successful cases, I created a survey to learn about the kind of technology and services that are preferred by seniors in Beijing. The main focus of this thesis is on how to improve senior-friendly transportation services in Beijing. First, the literature review will introduce how emerging new services affect seniors’ lifestyles, and the successful examples in other cities or countries. After this, it is necessary to learn what the elders’ specific travel needs in Beijing are by collecting survey responses —and then answer how transportation agencies should implement mobility services for the elderly. Last, I make recommendations regarding how to fill the elderly care services gap through new technology. The thesis is based on a mixed-research method. At first, I took the results from previous studies to identify senior-friendly transportation services. I included and analyzed successful examples and considered how to learn from these successes in Beijing. I created hypotheses of which kind of services would be most helpful to the elders. After that, I used a survey to determine the elders’ transportation preferences, understand their needs, and to rank the order of importance of the alternative services. I analyzed the survey results and based on the research, provided some suggestions about adding supporting facilities to public transportation systems, and some new technology, such as autonomous driving, as a future trend of senior-friendly transportation system. Additionally, door-to-door services for helping seniors travel in Beijing are highly desirable, and thus a community shuttle bus is an excellent service to consider

Cross-reactive immune responses to monkeypox virus induced by MVA vaccination in mice

Abstract Mpox (monkeypox) infection cases increased recently in non-Mpox outbreak areas, potentially causing an international threat. The desire to defend against a potential outbreak has led to renewed efforts to develop Mpox vaccines. In this report, mice were immunized with various doses of modified vaccinia virus Ankara (MVA) to evaluate the cross-reactive immune response of MVA immunization against protective antigens of the current monkeypox virus. We demonstrated that MVA induced specific antibodies against protective antigens (A29, A35, B6, M1, H3, and I1), mediating the neutralization abilities against the MVA and the monkeypox virus (MPXV). Moreover, recombinant protective antigens of the MPXV elicited cross-binding and cross-neutralizing activities for MVA. Hence, the MVA induced cross-reactive immune responses, which may guide future efforts to develop vaccines against the recent MPXV. Notably, compared to the other protective antigens, the predominant A29 and M1 antigens mediated higher cross-neutralizing immune responses against the MVA, which could serve as antigen targets for novel orthologous orthopoxvirus vaccine
