This research aims to assess the predictive accuracy of sentiment analysis in the stock market by constructing a reinforced model that integrates both sentiment and technical analysis. While prior studies have concentrated on social media sentiment for stock price prediction, this research introduces an enhanced model that combines sentiment analysis with technical indicators to improve the precision of stock market prediction. The study creates and evaluates predictive models for stock prices and trends using a substantial dataset of tweets from twenty prominent companies. Finally the re-enforced model has been developed and tested on the stock prices of: Apple, General Electric, Ford Motors and Amazon. The deliberate selection of these companies, each representing distinct industry sectors, serves a dual purpose. It not only facilitates a practical evaluation of our model across diverse market conditions but also ensures computational feasibility, allowing for a focused and detailed analysis of the model’s predictive accuracy and reliability in various economic landscapes. The study’s outcomes offer valuable insights into the effectiveness of the reinforced model, which combines sentiment and technical analysis to predict stock market movements, providing a more comprehensive approach to understanding market sentiment’s influence on stock prices. Furthermore, these findings contribute to the existing knowledge on stock market prediction techniques and emphasize the importance of considering multiple factors in decision-making.\u0000</p>","PeriodicalId":47264,"journal":{"name":"Electronic Commerce Research","volume":"21 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an example, we use perhaps the most serious misconception about PLS-SEM namely its alleged suitability for estimating the parameters of reflective measurement models. The Woozle effect is a cumulative process by which falsehoods become established as fact, and the self-correcting mechanisms of science are suspended. Through a literature review, we identify a number of factors that are likely to have contributed to the Woozle effect in the PLS-SEM literature.

This dynamic creates a natural competitive environment between the platforms and the TPSs. An increasingly prevalent strategy to enhance product competitiveness is the utilization of coupon promotions, which both platforms and TPSs have adopted. This study developed a theoretical model to study the dynamics of a retail system wherein an online platform facilitates the sale of products by a TPS, while simultaneously introducing products of differing quality levels. Four distinct promotion scenarios, based on whether the platform and TPS implement coupon offerings, are examined. The analysis outcomes reveal that coupon promotions initiated by both the platform and TPS result in reduced actual payments from consumers, particularly when the platform’s product holds a quality advantage. Surprisingly, in cases where the TPS’s product boasts a quality advantage, consumer actual payments may be higher in a promotion scenario compared to a non-promotional one. Furthermore, we demonstrate that the platform can leverage the TPS’s promotion efforts, particularly when commission fees and incremental purchases are on the higher side. Intriguingly, in situations where the TPS’s product holds a quality advantage, a co-promotion strategy, as opposed to a sole TPS-promotion approach, emerges as the optimal choice, especially when commission fees are substantial and incremental purchases are limited.</p>","PeriodicalId":47264,"journal":{"name":"Electronic Commerce Research","volume":"22 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By utilizing simulation techniques on the dynamic model, we have identified notable factors that impact the stability of the APP competition system, including: the adjustment speed of IHA, APP heterogeneity, and TPA fees. Our findings are as follows: (1) A higher adjustment speed of IHA leads to increased system instability, resulting in a chaotic state and reduced profitability for both IHA and TPA. (2) We discovered that APP competition systems with either high or low APP heterogeneity are more prone to instability. (3) In relation to TPA fees, higher fees tend to foster greater instability within the platform ecosystem, while also increasing IHA profits.

Some merchants require live streaming rooms to guarantee a minimum sales threshold in order to ensure their earnings. Based on certain variables, live streaming rooms can opt to utilize a \"guaranteed sales\" marketing strategy or a \"breakthrough sales\" marketing strategy. This study focuses on the live streaming e-commerce supply chain and considers factors such as streamers’ social influence and the live streaming room’s slotting allowance. We have developed a Stackelberg game model and designated the live streaming room (LSR) as the leader with partner merchants as followers. Optimal marketing effort level decisions and optimal discount rate decisions are studied under both the \"guaranteed sales\" and the \"breakthrough sales\" marketing strategies. We then consider whether variations in the slotting allowance charged by the LSR to the merchant have an impact. Our results indicate that the LSR’s optimal marketing strategy is mainly determined by the streamers’ social influence. When the streamers’ social influence is low, the LSR benefits more from the \"guaranteed sales\" marketing strategy; when it is high, the room benefits more from the \"breakthrough sales\" marketing strategy. For merchants, if there is no difference in the slotting allowance, then the merchant always makes more profit using the “breakthrough sales” strategy. If there is variation in the slotting allowance, the merchant's profit under the two strategies is uncertain. The greater the difference between the two marketing strategies, the greater the probability of choosing the \"breakthrough sales\" strategy.

The primary objective of this study is to harness the power of AI technology and (VCD) to stimulate economic expansion and enhance user experiences. Primarily, this study employs a literature review approach to systematically survey existing research on the application of AI in environmental design and analyzes case studies illustrating how VCD satisfies the requirements of environmental design. Subsequently, focusing on representative Landscape Environment Design (LED) projects, the study elucidates the practices of landscape environmental design under the support of VCD and AI technologies. Finally, through the collection of economic data, such as visitor numbers and revenue, before and after the integration of AI and VCD elements in the West Lake Wetland Park, located in Hangzhou, Zhejiang Province, an empirical analysis quantifies the variations in economic growth. The study assesses the impact of VCD elements, AI design elements, and environmental design changes on economic growth in the West Lake Wetland Park. The case analysis of the West Lake Wetland Park demonstrates a 20% increase in visitor numbers within a year after the integration of AI and VCD elements, and an accompanying 30% rise in commercial activity revenue by enhancing visitor experiences. Furthermore, the amalgamation of AI and visual communication in landscape design not only promotes sustainable development and energy conservation but also propels the growth of Gross Domestic Product (GDP) in the region. During the research period, the application of AI and VCD in landscape environmental design projects contributed to an approximately 15% increase in regional GDP. Based on the research findings, it can be deduced that the integration of AI technology and VCD holds substantial potential and opportunities within the realm of metaverse e-commerce. This integration has the capacity to propel economic growth and enhance user experience significantly.

Therefore, this study proposes a methodology for extracting color palettes to represent image sentiments, emphasizing the significance of color palettes as highlighted in various studies. Previous approaches to color palette extraction have included heuristic methods, survey-based selection, or utilizing clustering algorithms like K-means clustering based on color frequencies in images. In this study, we calculate the influence scores of colors for classifying image sentiments and propose deriving representative sentiment-color palettes based on these scores. Initially, we train a multi-label classification model to predict the sentiment labels of images and then create datasets for distorted images where pixels corresponding to specific colors are removed. By comparing the model outputs obtained from these distorted images with the original dataset, we obtain quantitative influence scores of colors for classifying sentiment labels. Furthermore, we extract sentiment-color palettes consisting of four important colors for 30 different sentiments.

Based on this background, we consider there are two strategies of an e-commerce platform to introduce a showroom channel, i.e., self-build strategy and cooperation strategy. Then we build theoretical models by characterising cost inefficiency of self-build strategy and information asymmetry of cooperation strategy in the platform supply chain. Next, we derive the optimal decisions under different strategies, and investigate the advantage of different strategies. Last, we explore the strategic introduction of the showroom channel in the platform supply chain. We find the following results. (1) Under cooperation strategy, the platform can strategically design two different cooperation contracts to the retailer, i.e., full incentive contract and partial incentive contract. Moreover, the retailer may be hurt by a higher demand due to information asymmetry under cooperation strategy. (2) Self-build strategy generates information advantage and cooperation strategy brings channel advantage, which jointly affect the optimal showroom channel strategy of the platform. To be more specific, when high-type demand of the retailer is relatively high and reservation profit of the retailer is relatively low, channel advantage dominates information advantage, then the platform will choose cooperation strategy.
