Special Issue Information

Dear Colleagues,

In the era of social media, users have changed the way they communicate, overcoming geographical distances. The shared content is a valuable, dynamic, and continually updated source of information that may be applied to different objectives for addressing marketing strategies, ad targeting, event detection and tracking, and so forth. Nevertheless, the nature of social media contents require Big and Fast Data enabled solutions, and the data value may be carried out only if we are able to filter out dirty and noisy data by also measuring the quality of information.

Over the years, much of the literature about social media analysis has focused on information extraction in order to guide recommender systems in different areas. However, social media contents often convey news, share information during critical events, support a political campaign, and so on. Further, it is sometimes difficult for users to recognize true information or evaluate the trustworthiness of its authors. Thus, it is also crucial to move attention towards these problems and evaluate the impact and new methods against the EU’s 2018 general data protection regulation (GDPR), recent events around information theft, and the role of social media in crime organization activities.

This Special Issue on "Advances in Social Media analysis" aims to collect recent advances in social media data stream analysis. In particular, we would like to collect works aiming to extract knowledge embedded in shared media (text, images, and video) for qualitative filtering, correlating, aggregating, summarizing, and turning data into usable understandable and actionable knowledge.

Potential topics include but are not limited to the following:

  • Quality of information on social media;
  • Information retrieval on social media;
  • Information ranking on social media;
  • Recommender systems;
  • Misinformation and fake news;
  • Social media marketing;
  • Topic detection and tracking;
  • Information summarization;
  • Security and privacy for social network and media;
  • Cloud-based data analysis for social network and media;
  • Social media analysis challenges and applications.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Information is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

The approach presented here introduces the use of directed and weighted graph indicators in order to incorporate the intensity of bilateral contacts. The indicators are tested on a reference email network, and their applicability in explaining the role of each individual in the organization is explored. The results suggest that directional indicators have high explicatory relevance and can add value to conventional Social Network Analysis (SNA) approaches. Full article

Intelligent agents have the potential to understand personality traits of human beings because of their every day interaction with us. The assessment of our psychological traits is a useful tool when we require them to simulate empathy. Since the creation of social media platforms, numerous studies dealt with measuring personality traits by gathering users’ information from their social media profiles. Real world applications showed how natural language processing combined with supervised machine learning algorithms are effective in this field. These applications have some limitations such as focusing on English text only and not considering polysemy in text. In this paper, we propose a multilingual model that handles polysemy by analyzing sentences as a semantic ensemble of interconnected words. The proposed approach processes Facebook posts from the myPersonality dataset and it turns them into a high-dimensional array of features, which are then exploited by a deep neural network architecture based on transformer to perform regression. We prove the effectiveness of our work by comparing the mean squared error of our model with existing baselines and the Kullback–Leibler divergence between the relative data distributions. We obtained state-of-the-art results in personality traits estimation from social media posts for all five personality traits. Full article

Burst analysis and prediction is a fundamental problem in social network analysis, since user activities have been shown to have an intrinsically bursty nature. Bursts may also be a signal of topics that are of growing real-world interest. Since bursts can be caused by exogenous phenomena and are indicative of burgeoning popularity, leveraging cross platform social media data may be valuable for predicting bursts within a single social media platform. A Long-Short-Term-Memory (LSTM) model is proposed in order to capture the temporal dependencies and associations based upon activity information. The data used to test the model was collected from Twitter, Github, and Reddit. Our results show that the LSTM based model is able to leverage the complex cross-platform dynamics to predict bursts. In situations where information gathering from platforms of concern is not possible the learned model can provide a prediction for whether bursts on another platform can be expected. Full article
