The economic causal chain is one example and refers to a cause-and-effect network structure among companies. It is constructed by extracting texts indicating causal relationships from the texts of financial statement summaries. A previous study showed there is a lead-lag effect that spreads to the ’effect’ stock group when a large stock price fluctuation in the ’cause’ stock group in the causal chain occurs. However, there is room for extracting a more robust lead-lag relationship by giving sentiment to the economic causal chain. The SSESTM (Supervised Sentiment Extraction via Screening and Topic Modeling) model has been proposed as a sentiment analysis specialized for stock return forecasting, and it produced a substantial profit in the U.S. and Japanese stock markets. In this study, we propose an investment strategy that exploits the lead-lag effect in the causal chain relationship considering the sentiments with the SSESTM model. We confirm the profitability of our proposed strategy and there is evidence of stock return predictability across causally linked companies considering sentiment.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122774289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the development of virtual reality technology, we can create environments in which people can practice without being exposed to certain dangers like traffic accidents that potentially occur in real environments. So far, many researches regarding car driving in VR have been developed, but little attention has been paid to analyzing and visualizing eye gaze data collected in VR education systems. Analyzing and visualizing the collected eye gaze data is potential to grasp information of whether learners overlooked objects such as traffic signals and signs. In this study, we developed a driving simulator in VR and collected eye tracking data from five university students while they were practicing driving using eye tracking technology. Also, we have developed a system that allows learners to reflect on their own driving using the collected their eye gaze data. We compared the changes in gaze between those who received feedback to improve their driving skills and those who did not. The results showed that the feedback was effective because it reduced the number of oversights while driving.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125782435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we aim to study the issues of innovative location-based e-commerce services built on social, mobility and contextual intelligence. Specifically, we explore the key elements of social, mobility, and contextual intelligence mechanism and prose a suite of important mobile commerce services. Founded on the established social, mobility, and context intelligence, we further propose a suite of innovative endorser advertising mechanism, which aims to find out those endorsers who have advertisement proneness and high sharing willingness in advertisement information diffusion, with a recommended list of potential advertisement receivers. Our mechanism propagates advertisement information in an efficiency way by helping consumers effortlessly filtering the advertisements fitting their preference, location, and context. On the other hand, it helps business propagate advertisements to the target consumers in an efficiency way.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114724325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In branding HEI, creating similar and differentiated images that students can easily associate with is essential. In addition, most students who enter HEI are interested in the academic content of HEI, but they have difficulty understanding the specialized academic content of HEI. This may cause a mismatch in the perception of academic content between students and HEI. Therefore, it is useful to extract images of similar and differentiated that students easily associate with specialized academic content. Comparing these images among departments will provide HEI with information useful for department branding and help students understand the department. The purpose of this study is to construct the following system using the syllabus. Specifically, this study aims to (1) quantitatively estimate POP courses by quantifying the similarity between courses using the syllabus and, (2) create an interdepartmental map that enables comparison among departments using POP by solving an optimization problem for course placement that minimizes the objective function.","PeriodicalId":156230,"journal":{"name":"2022 12th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129182246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
