The results of this analysis show that the houphouetist propaganda on Gbgagbo Laurent has three fundamental aspects. These are: fidelity to France, an outside economy and West African people migrants integration. Then, values extended by daily newspapers toward Gbagbo Laurent: aheros, a pan-africanist and a democrat. The end, this analysis show two caracteristic of this propaganda. These are: a resistant figtherto colonialism and continuing founder work.

Discretionary dissemination on Twitter

AbstractThe study provides large‐scale descriptive evidence on the timing and nature of corporate financial tweeting. Using an unsupervised machine learning approach to analyze 24 million tweets posted by S&P 1500 firms from 2012 to 2020, we find that firms are more likely to tweet financial information around significantly negative or positive news events, such as earnings announcements and the filing of financial statements. This convex U‐shaped relation between the likelihood of posting financial tweets and the materiality of accounting events becomes stronger over time. Whereas research based on early samples concludes that firms are less likely to disseminate financial information on Twitter when the news is bad and material, the symmetric dissemination behavior we find suggests that these conclusions should be revised. We also show that a machine learning algorithm (Twitter‐Latent Dirichlet Allocation) is superior to a dictionary approach in classifying short messages like tweets.

The Role of Photography in Breaking News Events: The Trump Assassination as an Example

This paper explores the role of photography in breaking news events through photographs taken by Evan Vucci during the Trump assassination. Using content analysis, the study analyzed 105 public articles to explore the visual guiding power of photography and how the media uses images to influence public opinion. The study found that photography can quickly attract public attention and influence the emotional level, while media can shape a specific narrative framework through selective display. The life of a news report lies in vividness, truth, and vividness. The same is true of news photography. Capturing real moments with both visual and emotional impact is the best news photo [1]. Meanwhile, it points out the shortcomings of China’s WeChat in reporting, such as ignoring the victims and the deep-rooted causes, and suggests that the media should reflect on the problems in reporting and take social responsibility. The study also offers suggestions for future reporting practices, emphasizing the key role of photojournalism in shaping public perception and the importance of media ethics. The limitation of the study is that the sample mainly focuses on WeChat, with a short timeframe, and future research will expand the sample and deepen the analysis of the audience’s psychological and emotional responses.

Application and Empirical Analysis of Random Volatility Model in Financial Markets

The Stochastic Volatility Model (SVM), as a key innovation in modern financial engineering, has profoundly changed our understanding of the volatility characteristics of financial markets. This model not only considers the volatility of asset prices as a time-varying random variable, but also simulates this uncertainty by introducing stochastic processes such as Brownian motion or more complex stochastic differential equations, thereby achieving a precise characterization of the dynamic characteristics of volatility. Compared to traditional fixed or historical average volatility assumptions, SVM can capture sudden changes in market sentiment, the impact of news events, and the influence of macroeconomic factors on volatility, providing investors with a more realistic perspective on the market. This article not only deeply analyzes the theoretical basis and construction methods of SVM, but also verifies its effectiveness and applicability in different financial market environments through empirical analysis and actual market data, providing valuable references and insights for financial practitioners, scholars, and policy makers.

The Construction of a Hybrid Media Storm: A Belgian Case Study

ABSTRACT In today's hybrid media system, amplified news events rage not only in “older” media such as legacy media but also on “newer” digital platforms such as online alternative news media outlets and social media. However, the role of both legacy news media and digital platforms in constructing events has been little explored. This study examines a hybrid media storm surrounding a Belgian political scandal in 2021. Based on a quantitative content analysis of 1,436 print and online articles from six Flemish newspapers and the public broadcaster’s website, 204 articles from three right-leaning alternative media, and 801 tweets between 1 February and 31 October 2021, the study reveals that digital platforms allow actors with little or no voice in legacy news media to influence the narrative of events on those platforms by actively promoting specific frames. Right-leaning alternative media's coverage, although less pluralistic than legacy media, still offers a broader frame repertoire than Twitter where the framing is one-sided. The case study shows that right-leaning alternative media and Twitter do not necessarily broaden the range of views, but are often a crucial factor in the amplification of specific frames at the expense of others.

Transmediatic depth of «The New York Times» and «El País» in their coverage of Boris Johnson’s resignation

A decade after the implementation of multimedia frameworks in the news media, it is necessary to determine which mechanisms have been incorporated into the daily routines of the news media. To accomplish this, we analysed the channels, forms and intertextual modalities employed by two leading international newspapers in their coverage of an unpredictable news event with global repercussions and a specific period: the UK government crisis of July 2022, which led to the resignation of the British Prime Minister Boris Johnson. We used a qualitative methodology of transmedia information analysis (Calvo & Serrano Tellería, 2021), adapted to assess the daily operations of online media in updating their content. Additionally, interviews were conducted with the teams responsible for this coverage. The coverage analysis revealed a transmedia depth of ten to eleven informative modalities. We found several residual differences in their audience participation policies. Certain generalist modalities, such as live streaming, video news, podcasts or social networks, were well established and used to attract readership. Furthermore, various models of newsletters and discussion forums with varying levels of access restriction were employed. However, neither of the studied media outlets offered an auditory transcription of their content. While a specific transmedia information model is emerging in digital media, further research should be undertaken to complement these findings.

Debates over the role of Traditional Chinese Medicine on COVID-19: A computational comparison between professionals and laypersons in Chinese online knowledge community

Leveraging a large collection of textual data (N = 21,539) from a Chinese online community, we employed structural topic modeling to investigate the thematic disparities between professionals and laypersons, regarding the effectiveness of Traditional Chinese Medicine (TCM) on COVID-19. Findings reveal that laypersons are the dominant communicators in terms of discussion volume, who often focus on relevant news events, societal or political aspects of TCM. In contrast, professionals keep concentrating on issues related to medical expertise, and do not shift attentions as frequent as laypersons. Despite the dominant influence of professionals on laypersons’ agenda, two-way agenda interactions identified confirm that lay public is empowered to negotiate with elite professionals under certain topics. Our results provide novel insights into the dynamic nature of attentions, behaviors, and relations among prominent communication actors, and encourage future research to examine the individual-level and societal-level impacts of these constructs in the emerging online media landscape.

A survey on temporal knowledge graph embedding: Models and applications

Knowledge graph embedding (KGE), as a pivotal technology in artificial intelligence, plays a significant role in enhancing the logical reasoning and management efficiency of downstream tasks in knowledge graphs (KGs). It maps the intricate structure of a KG to a continuous vector space. Conventional KGE techniques primarily focus on representing static data within a KG. However, in the real world, facts frequently change over time, as exemplified by evolving social relationships and news events. The effective utilization of embedding technologies to represent KGs that integrate temporal data has gained significant scholarly interest. This paper comprehensively reviews the existing methods for learning KG representations that incorporate temporal data. It offers a highly intuitive perspective by categorizing temporal KGE (TKGE) methods into seven main classes based on dynamic evolution models and extensions of static KGE. The review covers various aspects of TKGE, including the background, problem definition, symbolic representation, training process, commonly used datasets, evaluation schemes, and relevant research. Furthermore, detailed descriptions of related embedding models are provided, followed by an introduction to typical downstream tasks in temporal KG scenarios. Finally, the paper concludes by summarizing the challenges faced in TKGE and outlining future research directions.

Real-Time Extraction of News Events Based on BERT Model

Abstract For the large number of news reports generated every day, in order to obtain effective information from these unstructured news text data more efficiently. In this paper, we study the real-time crawling of news data from news websites through crawling techniques and propose a BERT model-based approach to extract events from news long text. In this study, NetEase news website is selected as an example for real-time extraction to crawl the news data of this website. BERT model as a pre-trained model based on two-way encoded representation of transformer performs well on natural language understanding and natural language generation tasks. In this study, we will fine-tune the training based on BERT model on news corpus related dataset and perform sequence annotation through CRF layer to finally complete the event extraction task. In this paper, the DUEE dataset is chosen to train the model, and the experiments show that the overall performance of the BERT model is better than other network models. Finally, the model of this paper is further optimised, using the ALBERT and RoBERTa models improved on the basis of the BERT model, experiments were conducted, the results show that both models are improved compared to the BERT model, the ALBERT model algorithm performs the best, the model algorithm's F1 value is 1% higher than that of BERT. The results show that the performance is optimised.

Geo-spatial hypertext in virtual reality: mapping and navigating global news event spaces

ABSTRACT Every day, a myriad of events take place that are documented and shared online through news articles from a variety of sources. As a result, as users navigate the Web, the volume of data can lead to information overload, making it difficult to find specific details about an event. We present News in Time and Space (NiTS) to address this issue: NiTS is a fully immersive system integrated into Va.Si.Li-Lab that organises textual information in a geospatial hypertext system in virtual reality. With NiTS, users can visualise, filter and interact with information currently based on GDELT on a virtual globe providing document networks to analyse global events and trends. The article describes NiTS, its event semantics and architecture. It evaluates NiTS in comparison to a classic search engine website, extended by NiTS's information filtering capabilities to make it comparable. Our comparison with this website technology, which is directly linked to the user's usage habits, shows that NiTS enables comparable information exploration even if the users have little or no experience with VR. That is, we observe an equivalent search result behaviour, but with the advantage that VR allows users to get their results with a higher level of usability without distracting them from their tasks. Through its integration with Va.Si.Li-Lab, a simulation-based learning environment, NiTS can be used in simulations of learning processes aimed at studying critical online reasoning, where Va.Si.Li-Lab guarantees that this can be done in relation to individual or groups of learners.

LEST: Large language models and spatio-temporal data analysis for enhanced Sino-US exchange rate forecasting

Exchange rate forecasting has a significant impact on a country’s balance of international payments, financial security and stability. Under the context of Sino-US trade war, a series of news events have happened thus increasing the abnormal fluctuations in the RMB exchange rate, and these fluctuations have made it more difficult to forecast the exchange rate. The analysis of news events’ impact on exchange rate fluctuations focused on assigning emotional labels to different economic news and political events by building an emotional lexicon. However, the previous method of using an offline emotional lexicon to analyze events could not be updated promptly making it difficult to better exploit implicit information of news events. Also, the offline emotional lexicon requires manual annotation of events which is unavoidable and subjective and therefore influences the sentiment analysis of the event. Therefore, we build a fusion forecasting framework of spatio-temporal and emotional information for accurate, real-time exchange rate forecasting. First, in the preprocessing phase, we leveraged the situational learning capabilities of Large Language Models (LLMs), specifically ChatGPT, combined with prompt engineering to enable ChatGPT to provide real-time, online, and precise automated sentiment analyses of Sino-US trade events. Second, we proposed the SG-TL fusion model, which integrates Spatio-Temporal Graph Convolutional Networks (STGCN) and Gated Recurrent Unit (GRU) models in the feature processing approach to accurately extract exchange rate features in spatial and temporal dimensions. We also employed Transformer and Long Short-Term Memory (LSTM) models in the forecasting phase to forecast the Sino-US exchange rates. Finally, Experiment results demonstrate that the exchange rate forecasting framework LEST can accurately capture the exchange rate fluctuations during the period of Sino-US trade war. Furthermore, its forecasting performance is more precise, efficient, and stable than existing works. The source code of our developed method is publicly available at https://gitee.com/andyham_andy.ham/lest-forecasting-framework.

Exploring the Correlation between Emojis and Mood Expression in Thai Twitter Discourse

Mood, a long-lasting affective state detached from specific stimuli, plays an important role in behavior. Although sentiment analysis and emotion classification have garnered attention, research on mood classification remains in its early stages. This study adopts a two-dimensional structure of affect, comprising ”pleasantness” and ”activation,” to classify mood patterns. Emojis, graphic symbols representing emotions and concepts, are widely used in computer-mediated communication. Unlike previous studies that consider emojis as direct labels for emotion or sentiment, this work uses a pre-trained large language model which integrates both text and emojis to develop a mood classification model. Our contributions are three-fold. First, we annotate 10,000 Thai tweets with mood to train the models and release the dataset to the public. Second, we show that emojis contribute to determining mood to a lesser extent than text, far from mapping directly to mood. Third, through the application of the trained model, we observe the correlation of moods during the Thai political turmoil of 2019-2020 on Thai Twitter and find a significant correlation. These moods closely reflect the news events and reveal one side of Thai public opinion during the turmoil.

“What the Heck Is Going on in the Group!”: Challenging Journalistic Authority by Pseudo-Professional WhatsApp News Groups

ABSTRACT This paper addresses the ways new entrants and mobile technologies have become significant challenges to the old news’ legitimacy models by focusing on pseudo-professional WhatsApp news groups from a journalistic authority standpoint. Based on a comparative textual analysis of how a breaking news event was handled by a leading Israeli pseudo-professional WhatsApp news group, compared to how it was covered by the Israeli News13 TV news broadcast, the findings indicate how, by adopting professional news practices and establishing unique relations of information exchange with traditional news outlets, journalistic authority is challenged by pseudo-professional WhatsApp news groups in today’s mobile news environment.

Analyzing the impact of financial news on the stock market using Natural Language Processing techniques

In the current financial domain, the impact of financial news on the stock market has become increasingly significant. Its rapid dissemination speed and wide coverage have made it a key factor in influencing investor sentiment and decision-making. Therefore, this study aims to explore how to utilize Natural Language Processing (NLP) technologies to analyze the impact of financial news on the stock market. The research involves collecting multiple sources of financial news and corresponding stock market data, and employs methods such as text preprocessing, sentiment analysis, and event extraction to process and analyze the news content. By constructing machine learning models, this study attempts to quantify the sentiment orientation of financial news and the impact of specific events on stock market volatility. The research questions focus on how to effectively extract valuable information from financial news and predict its specific impact on the stock market. The results indicate that sentiment orientation and key events in financial news are significantly correlated with short-term fluctuations in the stock market, especially for news reports on specific industries or companies. Moreover, the application of deep learning models further enhances the accuracy of predicting stock market reactions. This study not only provides financial market analysts with a new analytical tool but also offers a new perspective on understanding how financial news affects the stock market.

Retail investors and ESG news

An important debate exists around the extent to which retail investors make sustainable investments and, if they do, why. We contribute to this debate by investigating the aggregate trading patterns of retail investors around a comprehensive sample of key environmental, social, and governance (ESG) news events for U.S. firms. We show that ESG news events appear to be an important factor in retail investors’ portfolio allocation decisions. Yet, inconsistent with arguments about retail investors’ nonpecuniary preferences, our evidence shows that retail investors mainly trade on this information when they deem it financially material to a company’s stock performance. We also find their net trading demand predicts abnormal returns in the subsample of financially material events, consistent with retail traders benefiting from incorporating ESG-related information into their decision-making when it influences firm value. Overall we conclude that the average U.S. retail investor cares about firms’ ESG activities but primarily to the extent these activities matter for company financial performance.

The Ojai California Earthquake of 20 August 2023: Earthquake Early Warning Performance and Alert Recipient Response in the Mw 5.1 Event

Abstract A magnitude 5.1 earthquake in California rarely generates more than momentary notice—a headline in local newspapers and a mention with footage on the evening news—then fades into obscurity for most people. But this earthquake, which occurred near the city of Ojai, is important for seismologists, social scientists, emergency managers, policymakers, and others who are engaged in implementing and improving earthquake early warning (EEW) technology and in assessing its value in public warnings. In this earthquake, ShakeAlert, the EEW system for the West Coast of the United States operated by the U.S. Geological Survey (USGS), was publicly activated and, for the first time, a substantial number of those who received alerts provided feedback on various aspects of the alerts they received. To capture data related to public attitudes and assessments regarding this and future alerts, a supplemental questionnaire was developed and associated with the “Did You Feel It?” (DYFI) earthquake reporting system, also operated by the USGS. The DYFI system received over 14,000 felt reports; 2490 of these were by people who received or expected to receive an alert before the onset of earthquake motion at their locations. This article analyzes the aggregate results of these EEW user reports, touching on the respondent’s situation upon receiving the alert, characteristics of the alert received, and, perhaps, most importantly, how the alert recipient responded if received before feeling earthquake motion. The new DYFI EEW supplemental questionnaire also inquired about respondent views of alert usefulness and preferences in future alerts. Our report provides a first glimpse of a range of behaviors, attitudes, and assessments by users of the recently implemented EEW system for the U.S. West Coast.

Analisis Eksistensi Dan Urgensi Hakikat Pendidikan Kewarganegaraan Dalam Kasus Penyalahgunaan Narkotika Di Kalangan Selebritas Indonesia

Drug abuse among celebrities in Indonesia is increasingly widespread, as evidenced by the number of news events both on television, national news websites and even in magazines. Drug abuse among Indonesian celebrities seems to be a place of escape from the problems of the life they live. Of course, drug abuse can be detrimental to oneself, causing negative stigma, loss of work for the celebrity and others, especially if it is done by celebrities who can be a bad example for the community. Celebrities have an influential position in changing people's perspectives and mindsets. Drug abuse is a social problem that can be caused by factors that influence it, one of which is a lack of understanding of civic education. The importance of understanding and learning civic education from elementary school to college can change awake behavior and shape character in accordance with the value of the precepts contained in Pancasila. Civic education can be one part of prevention in some relevant cases, for example drug abuse. This is in line with the importance of civic education which has been explained in the Indonesian Law No.20 of 2003 concerning the national education system, chapter 10 regarding the curriculum, article 37 paragraphs 1 and 2 which explain that Civics Education is one of the lessons that are mandatory in the curriculum of basic education, secondary education to higher education. Character building in civic education will become a habit so that it cannot be influenced by the surrounding environment, so that drug abuse among celebrities only becomes a mere entertainment spectacle by the community and cannot be imitated and only becomes a lesson for bad examples in society.
