Summary:

People use online social platforms to express opinions about products and/or services in a wide range of domains, influencing the point of view and behavior of their peers. Understanding individuals’ satisfaction is a key element for businesses, policy makers, organizations, and social institutions to make decisions. This has led to a growing amount of interest within the scientific community, and, as a result, to a host of new challenges that need to be solved. Sentiment analysis methodologies have been investigated and employed by researchers in the past to provide methodologies and resources to stakeholders. In the field of machine learning, deep learning models which combine several neural networks have emerged and have become the state-of-the-art technologies in various domains for a variety of natural language processing tasks. The most prominent deep learning solutions are combined with word embeddings. However, how to include sentiment information in word-embedding representations to boost the performances of deep learning models, as well as explain what deep learning models (often employed as a black-box) learn are questions that still remain open and need further research and development.

The investigation of these key points will answer to why and how design choices for creating embedding representations and designing deep learning should be made. This goes toward the direction of Explainable Deep Learning (XDL), whose aim is to address how deep learning systems make decisions. This Special Issue aims to foster discussions about the design, development, and use of deep learning models and embedding representations which can help to improve state-of-the-art results, and at the same time enable interpreting and explaining the effectiveness of the use of deep learning for sentiment analysis. We invite theoretical works, implementations, and practical use cases that show benefits in the use of deep learning with a high focus on explainability for various domains.

The Special Issue is focused but not limited to these topics:

Deep learning topics:
- Deep learning topics
- Aspect-based DL and XDL models;
- Bias detection within DL and XDL for sentiment analysis;
- DL and XDL for toxicity and hate speech detection;
- Multilingual DL and XDL for sentiment analysis;
- DL and XDL for emotions detection;
- Weak-supervised DL and XDL for sentiment analysis;
- XDL design methodologies for sentiment analysis;
- Analysis of DL models for sentiment analysis.
Data representations topics
- Word embeddings for sentiment analysis;
- Knowledge graph and knowledge graph embeddings for sentiment analysis;
- Use of external knowledge (e.g., knowledge graphs) to feed DL for sentiment analysis;
- Combination of existing sentiment analysis resources (e.g., SenticNet) with embedding representations;
- Analysis of the performance of data representations for sentiment analysis tasks;
- Lexicon-based explainability for sentiment analysis.
Case studies
- Educational environments;
- Healthcare systems;
- Scholarly discussions (e.g., peer review process discussions, mailing lists, etc.);
- News platforms;
- Mental health systems;
- Social networks.
