Special Issue Information

Dear Colleagues,

Online social media (OSM) platforms are becoming one of the most effective tools of communication among people thanks to the fact that more than half of the world’s population are active OSM users. Thanks to the support supplied by OSM platforms, media can travel around the world at lightning speed. OSM can be employed for numerous purposes, including sharing news, providing a personal opinion on a subject, entertaining or educating oneself, and much more.

Therefore, it comes as no surprise that OSM sensing can be used as a source of data to understand people’s opinions as a whole. For example, a company may decide to conduct a series of studies concerning how their products are seen by customers.

On top of that, real-time OSM sensing can also be helpful in critical scenarios, such as in disaster or emergency response. Since OSM sensing is a relatively new topic, many challenges remain unsolved, and a lot more can be achieved, both in terms of methodologies and applications. Additionally, OSM sensing has some significant implications concerning how user privacy is managed and other ethical concerns.

This Special Issue therefore aims to put together original research and review articles on recent advances, technologies, solutions, applications, and new challenges in the field of Social Media Sensing.

Potential topics include but are not limited to:

  • Sensing in social media;
  • Social sensing methodologies;
  • Truth discovery and fake news detection;
  • Business intelligence;
  • Chatbot and Chatscripts;
  • Emotion recognition;
  • Artificial intelligence;
  • Privacy issues of social sensing;
  • Ethics of social sensing;
  • Event forecasting;
  • Sentiment analysis;
  • Social graph analysis;
  • Text analytics;
  • Economics and social effects;
  • Ubiquitous and pervasive crowd-sensing;
  • Semantic web;
  • Reputation and trust;
  • Nowcasting.

This paper discusses the importance of detecting breaking events in real time to help emergency response workers, and how social media can be used to process large amounts of data quickly. Most event detection techniques have focused on either images or text, but combining the two can improve performance. The authors present lessons learned from the Flood-related multimedia task in MediaEval2020, provide a dataset for reproducibility, and propose a new multimodal fusion method that uses Graph Neural Networks to combine image, text, and time information. Their method outperforms state-of-the-art approaches and can handle low-sample labelled data. Full article

Cyber-physical-social computing system integrates the interactions between cyber, physical, and social spaces by fusing information from these spaces. The result of this fusion can be used to drive many applications in areas such as intelligent transportation, smart cities, and healthcare. Situation Awareness was initially used in military services to provide knowledge of what is happening in a combat zone but has been used in many other areas such as disaster mitigation. Various applications have been developed to provide situation awareness using either IoT sensors or social media information spaces and, more recently, using both IoT sensors and social media information spaces. The information from these spaces is heterogeneous and, at their intersection, is sparse. In this paper, we propose a highly scalable, novel Cyber-physical-social Awareness (CPSA) platform that provides situation awareness by using and intersecting information from both IoT sensors and social media. By combining and fusing information from both social media and IoT sensors, the CPSA platform provides more comprehensive and accurate situation awareness than any other existing solutions that rely only on data from social media and IoT sensors. The CPSA platform achieves that by semantically describing and integrating the information extracted from sensors and social media spaces and intersects this information for enriching situation awareness. The CPSA platform uses user-provided situation models to refine and intersect cyber, physical, and social information. The CPSA platform analyses social media and IoT data using pretrained machine learning models deployed in the cloud, and provides coordination between information sources and fault tolerance. The paper describes the implementation and evaluation of the CPSA platform. The evaluation of the CPSA platform is measured in terms of capabilities such as the ability to semantically describe and integrate heterogenous information, fault tolerance, and time constraints such as processing time and throughput when performing real-world experiments. The evaluation shows that the CPSA platform can reliably process and intersect with large volumes of IoT sensor and social media data to provide enhanced situation awareness. Full article

Hashtags have been an integral element of social media platforms over the years and are widely used by users to promote, organize and connect users. Despite the intensive use of hashtags, there is no basis for using congruous tags, which causes the creation of many unrelated contents in hashtag searches. The presence of mismatched content in the hashtag creates many problems for individuals and brands. Although several methods have been presented to solve the problem by recommending hashtags based on the users’ interest, the detection and analysis of the characteristics of these repetitive contents with irrelevant hashtags have rarely been addressed. To this end, we propose a novel hybrid deep learning hashtag incongruity detection by fusing visual and textual modality. We fine-tune BERT and ResNet50 pre-trained models to encode textual and visual information to encode textual and visual data simultaneously. We further attempt to show the capability of logo detection and face recognition in discriminating images. To extract faces, we introduce a pipeline that ranks faces based on the number of times they appear on Instagram accounts using face clustering. Moreover, we conduct our analysis and experiments on a dataset of Instagram posts that we collect from hashtags related to brands and celebrities. Unlike the existing works, we analyze these contents from both content and user perspectives and show a significant difference between data. In light of our results, we show that our multimodal model outperforms other models and the effectiveness of object detection in detecting mismatched information. Full article
