This study explores these viewers’ emotional states that can be detected through facial expressions, as well as their perceived hedonic liking of the product. The study consists of five experiments, one per product/stimulus including hedonic and utilitarian foods. Seventy-six viewers successfully participated in the tasks, and 164 valid video records were analyzed by FaceReader Online. The results indicated that FaceReader Online can capture differences in emotional responses elicited by different types of food and media posts in social media marketing campaigns. Sadness prevailed all other emotions throughout the campaigns, while arousal remained at levels of inactivity. The responses in the hedonic product campaign were significantly less negative (in terms of sadness and anger) than those in the campaigns of utilitarian products. The hedonic liking ratings indicated significant differences among campaigns of similar content and media characteristics, implying the determinant role of other factors, like individual product preferences and sensory expectations. The results contribute to understanding consumer emotions during watching food related campaigns in social media.","PeriodicalId":432172,"journal":{"name":"2022 17th International Workshop on Semantic and Social Media Adaptation & Personalization (SMAP)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126041143","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}

However, a simple “presentation” of processes, or the absence of necessary further explanation and communication with the specialists, may be problematic in terms of what visitors eventually see and understand. The exploitation of digital media and their efficient management and interlinking to meaningful data and knowledge may contribute significantly to the dissemination of publicly available information and the support of OpenLabs. Considering all the above, the CAnTi (Conservation of Ancient Tiryns) research project aims to design and implement virtual and augmented reality interactive applications that will visualize the conservation and restoration (CnR) data of the Acropolis of Ancient Tiryns. The digital content of the applications will be modeled using Semantic Web (SW) technologies, providing cultural visitors with access to insight documentation data and media produced by CnR scientists. The applications will constitute a part of the OpenLab activities that will be carried out on the archaeological site, enhancing the visitors’ experience regarding the CnR of the site’s current practices and past.","PeriodicalId":432172,"journal":{"name":"2022 17th International Workshop on Semantic and Social Media Adaptation & Personalization (SMAP)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114055384","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}

What changed during the past decades and can be exploited towards greater good is the adoption of web and social media. In this paper, the main focus delves around smart retrieving of information from online sources, such as Twitter, YouTube and culturally-dedicated websites to provide cultural experts with relevant multimedia. The final scope is to build immersive experiences about migrant stories for local communities towards a more inclusive Europe. Moreover, semantic web technologies are deployed to homogenize multi-modal data and metadata into a unified knowledge graph including ontological structures for precise annotations. Additionally, this enables knowledge extraction and insights acquisition from implicit relationships.

Nevertheless, the majority of the elements comprising the strategic culture of higher education have been forged with different objectives in mind. Therefore, in order for higher education institutions to remain highly relevant, a thorough review and renewal of this culture is required. This potentially radical transformation can be greatly facilitated through a set of behavioral techniques explicitly designed to encourage the shift from an outdated but familiar situation to a beneficial but unknown one. To corroborate the validity and feasibility of the proposed transition methodologies, successful applications of behavioral principles to all levels of education around the globe are provided and discussed. Moreover, evaluation metrics for assessing the results of a behavioral strategy are given.","PeriodicalId":432172,"journal":{"name":"2022 17th International Workshop on Semantic and Social Media Adaptation & Personalization (SMAP)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131749423","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}

A typical method to this goal is to construct a visual summary, which is significantly more expressive than other alternatives, such as verbal annotations. In this paper, we describe a video summarization technique which is based on the extraction and the fusion of audio and visual data, in order to generate dynamic video summaries, i.e., video summaries that include the most essential video segments from the original video, while maintaining their original temporal sequence. Based on the extracted features, each video segment is classified as being “interesting” or “uninteresting,” and hence included or excluded from the final summary. The originality of our technique is that prior to classification, we employ a transfer learning strategy to extract deep features from pre-trained models as input to the classifiers, making them more intuitive and robust to objectiveness. We evaluate our technique on a large dataset of user-generated videos and demonstrate that the addition of deep features is able to improve classification performance, resulting in more concrete video summaries, compared to the use of only hand-crafted features.","PeriodicalId":432172,"journal":{"name":"2022 17th International Workshop on Semantic and Social Media Adaptation & Personalization (SMAP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130024304","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}

Retail and logistics companies struggle to find strategies that offer a successful and fast last-mile delivery service that satisfies consumers’ preferences and expectations. Last-mile delivery is an opportunity, as well as a challenge for e-commerce retailers and logistics companies because it needs to satisfy customers’ preferences, offering the best customer experience. This paper explores Greek consumers’ preferences of last-mile delivery alternatives. We investigate the potential of using drone delivery and the challenges the consumers face during tracking their order delivery. We conducted a survey with 174 participants exploring their online shopping behavior, which delivery options they prefer, what delivery challenges they face (e.g. home delivery without prior notice) and which factors influence their delivery decisions (e.g. delivery time-flexibility and time saving).

One key challenge is to detect the engagement and other affective states exhibited by students during online learning. This paper investigates the capabilities and limitations of neural networks to distinguish between different affective states (i.e., boredom, engagement, confusion, and frustration), and their intensity level (i.e., very low, low, high, and very high). Several models are built using a hybrid ResNet+TCN neural network architecture. The models are trained using a large dataset, DAiSEE, that contains short 10 second video recordings of students as they watch educational content ‘in the wild’. A second dataset consisting of longer videos, EmotiW2020, is used to cross validate the engagement level classification model. The affective state classification model outperforms prior models. Boredom, confusion and frustration level classification models outperform or are on par with prior models. The engagement level classification model achieved similar performance with other baseline models and was outperformed by some SOTA models, but those models used 5 times more frames and 5 to 10 times more training epochs. The engagement level classification model was validated and achieved similar performance on both the DAiSEE and EmotiW2020 datasets.","PeriodicalId":432172,"journal":{"name":"2022 17th International Workshop on Semantic and Social Media Adaptation & Personalization (SMAP)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117326539","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}
