BACKGROUND Allergic rhinitis (AR) is a chronic disease, and several risk factors predispose individuals to the condition in their daily lives, including exposure allergens inhalation irritants. Analyzing potential that can trigger AR provide reference material for use reduce its occurrence lives. Nowadays, social media part of life, with an increasing number people using at least 1 platform regularly. Social enables users share experiences among large groups who same interests experience afflictions. Notably, these channels promote ability health information. OBJECTIVE This study aims construct intelligent method (TopicS-ClusterREV) identifying based on comments. The main questions were as follows: How many comments contained factor information? categories be summarized into? do AR? METHODS crawled all data from May 2012 2022 under topic <i>allergic rhinitis</i> Zhihu, obtaining total 9628 posts 33,747 We improved Skip-gram model train topic-enhanced word vector representations (TopicS) then vectorized annotated text items training classifier.

Purpose This study explores the intricate relationship between unemployment rates and emotional responses among Chinese university graduates, analyzing how these factors correlate with specific linguistic features on popular social media platform Sina Weibo. The goal is to uncover patterns that elucidate psychological dimensions of challenges this demographic. Methods analysis utilized a dataset 30,540 Weibo posts containing keywords related anxiety, collected from January 2019 June 2023. were pre-processed eliminate noise refine data quality. Linear regression textual analyses employed identify correlations for individuals aged 16–24 characteristics posts. Results found significant fluctuations in urban youth rates, peaking at 21.3% A corresponding increase anxiety-related expressions was noted posts, peak aligning high rates. Linguistic revealed category “Affect” showed strong positive correlation indicating increased expression alongside rising unemployment. Other categories such as “Negative emotion” “Sadness” also correlations, highlighting robust economic distress. Conclusion findings underscore profound impact well-being students, suggesting hardships are closely linked stress heightened negative emotions. contributes holistic understanding socio-economic faced by young adults, advocating comprehensive support systems address both facets

BACKGROUND Depression is a significant global public health issue that affects the physical and mental well-being of hundreds millions people worldwide. However, substantial number individuals with depression on social media often go undiagnosed struggle to access timely effective treatment, increasingly becoming major societal concern. OBJECTIVE This paper aims explore develop an online risk detection method based deep learning technology identify at Chinese platform Sina Weibo. METHODS We initially collected approximately 527,333 posts publicly shared over one year from 1600 without Weibo platform. Subsequently, we developed hierarchical Transformer network learn semantic features for each user. comprises two levels structures, word level other sentence level. These Transformers are employed extract textual post, aggregated all user generate user-level features. A classifier then applied predict depression. Finally, conducted statistical linguistic analyses content using LIWC. RESULTS divided original dataset into training, validation, test sets. The training set consists 1000 100 validation includes 600 users, 300 Our achieved accuracy 84.62%, precision 84.43%, recall 84.50%, F1 score 84.32% applying sampling techniques.

Abstract Background Depression represents a pressing global public health concern, impacting the physical and mental well-being of hundreds millions worldwide. Notwithstanding advances in clinical practice, an alarming number individuals at risk for depression continue to face significant barriers timely diagnosis effective treatment, thereby exacerbating burgeoning social crisis. Objective This study seeks develop novel online detection method using natural language processing technology identify on Chinese media platform Sina Weibo. Methods First, we collected approximately 527,333 posts publicly shared over 1 year from 1600 with without Weibo platform. We then developed hierarchical transformer network learning user-level semantic representations, which consists 3 primary components: word-level encoder, post-level aggregation encoder. The encoder learns embeddings individual posts, while explores features user post sequences. aggregates sequence semantics generate representation that can be classified as depressed or nondepressed. Next, classifier is employed predict depression. Finally, conducted statistical linguistic analyses content Linguistic Inquiry Word Count. Results divided original data set into training, validation, test sets. training consisted 1000 Similarly, each validation comprised 600 users, 300 both cohorts (depression nondepression). Our achieved accuracy 84.62%, precision 84.43%, recall 84.50%, F -score 84.32% employing sampling techniques. However, by applying our proposed retrieval-based strategy, observed improvements performance: 95.46%, 95.30%, 95.70%, 95.43%. These outstanding results clearly demonstrate effectiveness superiority model technique. breakthrough provides new insights large-scale through media. Through behavior analysis, discovered are more likely use negation words (the value “swear” 0.001253). may indicate presence negative emotions, rejection, doubt, disagreement, aversion Additionally, analysis revealed tend emotional vocabulary their expressions (“NegEmo”: 0.022306; “Anx”: 0.003829; “Anger”: 0.004327; “Sad”: 0.005740), reflect internal emotions psychological state. frequent could way express feelings toward life, themselves, surrounding environment.

Background Implementing machine learning prediction of negative attitudes towards suicide may improve health outcomes. However, in previous studies, varied forms were not adequately considered, and developed models lacked rigorous external validation. By analyzing a large-scale social media dataset (Sina Weibo), this paper aims to fully cover develop classification model for predicting as whole, then externally validate its performance on population individual levels. Methods 938,866 Weibo posts with relevant keywords downloaded, including 737,849 updated between 2009 2014 ( 2009–2014 ), 201,017 2015 2020 2015–2020 ). (1) For development, based 10,000 randomly selected from , human-based content analysis was performed manually determine labels each post (non-negative or attitudes). Then, computer-based conducted automatically extract psycholinguistic features the same posts. Finally, features. (2) validation, level, implemented remaining 727,849 validated by comparing proportions predicted human-coded results. Besides, similar analyses 300 actual Results F1 area under ROC curve (AUC) values reached 0.93 0.97. significant differences but very small effect sizes observed whole sample χ 2 1 = 32.35, p &lt; 0.001; Cramer’s V 0.007, 0.001), men 9.48, 0.002; 0.005, 0.002), women 25.34, 0.009, 0.001). AUC 0.76 0.74. Conclusion This study demonstrates efficiency necessity confirms that validation is essential before implementing into practice.
