Integrating machine translation into MOOCS
This paper presents TraMOOC (Translation for Massive Open Online Courses), a European research
project developed with the intention of empowering international learners in the digital multilingual
world by providing reliable machine translation (MT) specifically tailored to MOOCs from English into
11 languages (Bulgarian, Chinese, Croatian, Czech, Dutch, German, Greek, Italian, Polish,
Portuguese, and Russian). The paper describes how the project is addressing the challenges involved
in developing an innovative, high-quality MT service for producing accurate translations of
heterogeneous multi-genre MOOC materials, encompassing subtitles of video lectures, assignments,
tutorials, and social web text posted on student blogs and fora. Based on the results of a large-scale
and multi-method evaluation conducted as part of the TraMOOC project, we offer a reflection on how
to best integrate state-of-the-art MT into MOOC platforms. The conclusion summarizes the key
lessons learned, that can be applied by the wider community of international professionals with an
interest in the multilingual aspects of innovative education and new learning technologies
Teaching practice tasks
Publikacja recenzowana / Peer-reviewed publicationTeaching Practice Tasks has been designed for students of initial teacher training courses who are about to start their teaching practice. The book contains a set of materials that provide guidance and enable trainees to keep record of their development at the beginning of their teaching career. The book may be used by institutions which organize their studentsâ teaching practice in cooperation with school-based mentors. The tasks offered in the book may be used by teacher trainers and mentors as a tool to check and assess traineesâ progress.
The book may be particularly helpful in supervision of extra-mural and distance learning students, who because of geographical and time constraints may wish to take up their teaching practice at their local schools. Teacher training institutions may find visiting student teachers in their home places almost impossible and a written record of teaching experience can provide a reliable alternative.
What does the book contain?
The book contains a range of tasks that will help trainees to develop skills necessary in the teaching profession. The materials may be divided into the following: Reflection tasks, Observation tasks, Team / solo teaching tasks, Materials for Teaching Practice supervisor
Why paper mills clean up : determinants of pollution abatement in four Asian countries
The authors find strong evidence that despite weak or nonexistent formal regulation and enforcement of environmental standards, many plants in South and Southeast Asia are clean. At the same time, many plants are among the world's worst polluters. To account for the extreme variation among plants, the authors review evidence from a survey of pollution abatement by 26 pulp and paper plants in four countries: Bangladesh, India, Indonesia, and Thailand. They incorporate 3 sets of factors affecting pollution intensity: plant characteristics, economic considerations, and external pressure from the government and private stakeholders. They find that the level of pollution abatement is positively associated with scale and competitiveness, negatively associated with public ownership, and unaffected by foreign links (in ownership or financing). Informal regulation, or community pressure on plants works to abate pollution, with high income being a powerful predictor of effectiveness. Privatization, to the extent that it increases plant efficiency, can significantly improve environmental performance. To prevent environmental injustice in poor or marginalized communities, the authors conclude, governments may want to consider strategies for improving their participation, and may want to target regulation to address pollution problems among them.Environmental Economics&Policies,Water and Industry,Water Conservation,Pollution Management&Control,Sanitation and Sewerage,Environmental Economics&Policies,Water and Industry,Pollution Management&Control,Sanitation and Sewerage,TF030632-DANISH CTF - FY05 (DAC PART COUNTRIES GNP PER CAPITA BELOW USD 2,500/AL
Methods of covert communication of speech signals based on a bio-inspired principle
This work presents two speech hiding methods based on a bio-inspired concept known as the ability of adaptation of speech signals. A cryptographic model uses the adaptation to transform a secret message to a non-sensitive target speech signal, and then, the scrambled speech signal is an intelligible signal. The residual intelligibility is extremely low and it is appropriate to transmit secure speech signals. On the other hand, in a steganographic model, the adapted speech signal is hidden into a host signal by using indirect substitution or direct substitution. In the first case, the scheme is known as Efficient Wavelet Masking (EWM), and in the second case, it is known as improved-EWM (iEWM). While EWM demonstrated to be highly statistical transparent, the second one, iEWM, demonstrated to be highly robust against signal manipulations. Finally, with the purpose to transmit secure speech signals in real-time operation, a hardware-based scheme is proposedEsta tesis presenta dos mĂ©todos de comunicaciĂłn encubierta de señales de voz utilizando un concepto bio-inspirado, conocido como la âhabilidad de adaptaciĂłn de señales de vozâ. El modelo de criptografĂa utiliza la adaptaciĂłn para transformar un mensaje secreto a una señal de voz no confidencial, obteniendo una señal de voz encriptada legible. Este mĂ©todo es apropiado para transmitir señales de voz seguras porque en la señal encriptada no quedan rastros del mensaje secreto original. En el caso de esteganografĂa, la señal de voz adaptada se oculta en una señal de voz huĂ©sped, utilizando sustituciĂłn directa o indirecta. En el primer caso el esquema se denomina EWM y en el segundo caso iEWM. EWM demostrĂł ser altamente transparente, mientras que iEWM demostrĂł ser altamente robusto contra manipulaciones de señal. Finalmente, con el propĂłsito de transmitir señales de voz seguras en tiempo real, se propone un esquema para dispositivos hardware
Is ChatGPT a Good Recommender? A Preliminary Study
Recommendation systems have witnessed significant advancements and have been
widely used over the past decades. However, most traditional recommendation
methods are task-specific and therefore lack efficient generalization ability.
Recently, the emergence of ChatGPT has significantly advanced NLP tasks by
enhancing the capabilities of conversational models. Nonetheless, the
application of ChatGPT in the recommendation domain has not been thoroughly
investigated. In this paper, we employ ChatGPT as a general-purpose
recommendation model to explore its potential for transferring extensive
linguistic and world knowledge acquired from large-scale corpora to
recommendation scenarios. Specifically, we design a set of prompts and evaluate
ChatGPT's performance on five recommendation scenarios. Unlike traditional
recommendation methods, we do not fine-tune ChatGPT during the entire
evaluation process, relying only on the prompts themselves to convert
recommendation tasks into natural language tasks. Further, we explore the use
of few-shot prompting to inject interaction information that contains user
potential interest to help ChatGPT better understand user needs and interests.
Comprehensive experimental results on Amazon Beauty dataset show that ChatGPT
has achieved promising results in certain tasks and is capable of reaching the
baseline level in others. We conduct human evaluations on two
explainability-oriented tasks to more accurately evaluate the quality of
contents generated by different models. And the human evaluations show ChatGPT
can truly understand the provided information and generate clearer and more
reasonable results. We hope that our study can inspire researchers to further
explore the potential of language models like ChatGPT to improve recommendation
performance and contribute to the advancement of the recommendation systems

Exploration of WEB resources in the domain of metal processing technologies
The amount of information contained in the WEB grows in a galloping way, which is caused by the spread of Internet access and lowering the cost of storing and sharing data across the network. The vast amount of data, impossible to be analyzed by human, is the reason why finding and selecting valuable information has become a serious problem. Due to this situation, a highly useful and desired solution would be the development of a system that would allow continuous monitoring of the WEB and finding for the user valuable information from the selected Internet resources. This paper describes the concept of such a system, along with its initial implementation and application to search for information in the field of foundry industry
