Special Issue Information

Dear Colleagues,

In recent years, huge progress has been made in natural language processing. Initially, this progress has been related to the advent of large language models. We must acknowledge that state-of-the-art language processing and understanding systems are almost able to reach a level of performance that is close to humans, at least in some areas and applications. But still, there are lots of problems that require further analysis and investigation. How much data do we need to reach a human-level performance? Do we really need such large amounts of data? We as humans can learn from a much smaller amount of data. How can we guarantee that the model in one language will be adequately transferred to another language?  How can text generation systems add emotional content to the text messages in a close-to-human way? These are only a few examples of the questions that require further research and new ideas and solutions. Of course, this is not an exhaustive list of problems that the research community faces in the area of natural language processing.

In this context, for the Special Issue entitled “Advances in Natural Language Processing and Their Applications”, we invite original research and comprehensive reviews on, but not limited to, the following areas:

  • Architecture for the natural language processing systems;
  • Advances in feature extraction for natural language processing;
  • Datasets and their properties for natural language processing systems;
  • Language differences and how to deal with them;
  • Words and phrases with multiple meanings;
  • Methods to speed up the development and reduce the costs of NLP systems;
  • Differences between human- and computer-generated text perception;
  • Discrimination between human- and computer-generated texts;
  • Advances in sentiment analysis;
  • Dealing with misspellings;
  • Advances in NLP applications;

And others.

Aspect-level sentiment classification has received more and more attention from both academia and industry due to its ability to provide more fine-grained sentiment information. Recent studies have demonstrated that models incorporating dependency syntax information can more effectively capture the aspect-specific context, leading to improved performance. However, existing studies have two shortcomings: (1) they only utilize dependency relations between words, neglecting the types of these dependencies, and (2) they often predict the sentiment polarity of each aspect independently, disregarding the sentiment relationships between multiple aspects in a sentence. To address the above issues, we propose an aspect-level sentiment classification model based on a hybrid graph neural network. The core of our model involves constructing several hybrid graph neural network layers, designed to transfer information among words, between words and aspects, and among aspects. In the process of information transmission, our model takes into account not only dependency relations and their types between words but also sentiment relationships between aspects. Our experimental results based on three commonly used datasets demonstrate that the proposed model achieves a performance that is comparable to or better than recent benchmark methods. Full article
