Distribution-aware hybrid noise augmentation in graph contrastive learning for recommendation

The recommender systems are one of the most effective big data tools for solving the information overload problem, but data sparsity greatly affects its performance. However, most of the existing graph-based contrastive learning methods perturb the original graph structure for data augmentation, which may lead to semantic loss and subsequently degrade the recommendation performance. Meanwhile, studies have shown that improving the uniformity of data distribution is more effective than data augmentation using graph perturbation. In this paper, to enhance the uniformity of data distribution, we propose Distribution-Aware Hybrid Noise augmentation in graph contrastive learning for Recommendation (DAHNRec). Specifically, we design distribution-aware hybrid noise augmentation (DAHN) method to generate noise suitable for the users and items, instead of simply utilizing random noise following uniform distributions. By applying DAHN, the model can learn the appropriate noise distribution during the training process to enhance the uniformity of the embedding space. Additionally, we propose Balanced Bayesian Personalized Ranking (BBPR) as the loss function for recommendation tasks to improve difference characterizing between positive and negative samples. This improves the ranking tasks’ performance. Furthermore, we conduct extensive experiments based on public benchmark datasets. The results indicate that DAHNRec outperforms several existing methods. Furthermore, DAHNRec is a general recommendation model based on user–item interactions, which can be used to improve the recommendation performance in various real-world scenarios, such as e-commerce platforms and social media.

Корпусная интерпретация англоязычного экологического дискурса: лингвистические закономерности и функциональные особенности

English-language environmental speech has its own linguistic features. Ecological discourse is a relevant, self-sufficient, and highly identical communication continuum. This article introduces a corpus analysis of the English-language environmental discourse with its linguistic patterns and functional interpretation. The texts were considered not as static linguistic objects, but as a system of functional features in speech. The English-language research material was authentic and featured various environmental issues. Corpus analysis is a popular and reliable tool for big linguistic data while the corpus-discursive methodology proved to be an effective interdisciplinary tool. It was applied to the EuroNews Green Corpus, aggregated from 506 English-language texts on environmental issues. This innovative type of corpus can be qualified as instrumentally independent. The research proved the effectiveness of universal case managers or case shells of open architecture, e.g., Sketch Engine. Not only did it manage to collect the data, but also performed quite a complex structure analysis, interpreting, and discourse modeling. Corpus linguistics is looking for qualitatively new opportunities to identify complex linguistic relations. The case study provided a comprehensive description of environmental discourse as an object of linguistic research. Based on statistic details, the authors analyzed the categories of tokens, keywords, and terms to structure them as lemmas, collocations, and n-grams, which were presented as metadata. The metadata modeling provided concordances, thesauruses, and frequency glossaries. Environmental discourse had a pronounced lexical and semantic uniqueness resulting from specific ecological terminology. However, the multidimensional corpus analysis revealed an extremely low frequency of the key concept of ecology. Thus, this corpus study of the English-language ecological discourse demonstrated a good potential for further linguistic research.

Digital Footprint: Assessing Student Satisfaction with Education Quality

The COVID-19 pandemic has changed the way learning is organized around the world. Russian universities have also been faced with the need to quickly transfer all teaching to an online format. The importance of student satisfaction with the education quality in online learning is increasing, since it is an important condition for motivation. The paper shows that based on the analysis of students’ messages in the social network, it is possible to observe and analyze the overall dynamics and trends in student community satisfaction with the quality of the learning / the efficiency of universities and conduct a comparative analysis of the identified characteristic data groups with their totality. It is shown that the data on the reaction of students of a particular university may have significant deviations from the totality of data, which reflects the characteristics of the reaction of students of a particular university to events occurring at the same time. This may indicate the internal differences of the university, which form an appropriate response to external events.To understand the satisfaction of students in the transition to a new implementation format of the learning. The digital traces of students from the social network VKontakte were analyzed using individual Big Data tools on the PolyAnalyst software platform. This made it possible to trace changes in the mood of students and, on the example of a single university, to identify and explain deviations in the attitude of students to the implementation of the learning, as well as to verify the methodology. The methodology developed by authors makes it possible to detect problematic issues in the university, including the moment of their occurrence, relevance, degree of concern of students. Such content analysis can be used not only to assess students’ satisfaction with the quality of the learning, but also to monitor the emergence of any problems that cause concern and strong reactions on the part of the student community, as well as other communities and individual groups.
