Special Issue Information

Dear Colleagues,

We are delighted to announce the introduction of a Special Issue in Big Data and Cognitive Computing (BDCC), dedicated to the exploration of Large Language Models (LLMs). In recent years, LLMs have emerged as transformative tools with the potential to revolutionize various aspects of language understanding, generation, and manipulation.

The advent of models like GPT-3 has opened up new possibilities for natural language processing, understanding, and generation on an unprecedented scale. LLMs, with their ability to comprehend context, learn patterns, and generate coherent text, have found applications in diverse domains, including but not limited to education, healthcare, content creation, and customer support.

This Special Issue aims to bring together researchers and practitioners to share their insights, findings, and advancements in the field of Large Language Models. We encourage the submission of original research papers and comprehensive reviews on topics related to LLMs, including but not limited to the following:

  • Novel architectures and training techniques;
  • Efficient training strategies for scaling up language models;
  • Applications of large language models;
  • Ethical considerations and bias mitigation;
  • Evaluation metrics and benchmarks.

We invite researchers, academics, and industry professionals to contribute to this Special Issue and help shape the future of Large Language Models. Submissions can include original research, case studies, and reviews that shed light on the challenges, advancements, and applications of LLMs.

We look forward to your valuable contributions and the collective advancement of knowledge in the exciting field of Large Language Models.

The popularity of ChatGPT has raised questions surrounding AI’s potential for health use cases. Since the release of ChatGPT in 2022, social media users have shared their prompts and ChatGPT responses on different topics such as health. Despite editorials and opinion articles discussing the potential uses of ChatGPT, there is a lack of a systematic approach to identify and analyze the use cases of ChatGPT in health. This study establishes a framework for gathering and identifying tweets (i.e., posts on social media site “X”, formerly known as Twitter) that discuss health use cases of ChatGPT, integrating topic modeling with constructivist grounded theory (CGT) to organize these topics into common categories. Using this framework, nine topics were identified, which were further grouped into four categories: (1) Clinical Workflow, (2) Wellness, (3), Diseases, and (4) Gender Identity. The Clinical Workflow category was the most popular category, and included four topics: (1) Seeking Advice, (2) Clinical Documentation, (3) Medical Diagnosis, and (4) Medical Treatment. Among the identified topics, “Diet and Workout Plans” was the most popular topic. This research highlights the potential of social media to identify the health use cases and potential health applications of an AI-based chatbot such as ChatGPT. The identified topics and categories can be beneficial for researchers, professionals, companies, and policymakers working on health use cases of AI chatbots. Full article

Large language models (LLMs) can store factual knowledge within their parameters and have achieved superior results in question-answering tasks. However, challenges persist in providing provenance for their decisions and keeping their knowledge up to date. Some approaches aim to address these challenges by combining external knowledge with parametric memory. In contrast, our proposed QA-RAG solution relies solely on the data stored within an external knowledge base, specifically a dense vector index database. In this paper, we compare RAG configurations using two LLMs—Llama 2b and 13b—systematically examining their performance in three key RAG capabilities: noise robustness, knowledge gap detection, and external truth integration. The evaluation reveals that while our approach achieves an accuracy of 83.3%, showcasing its effectiveness across all baselines, the model still struggles significantly in terms of external truth integration. These findings suggest that considerable work is still required to fully leverage RAG in question-answering tasks. Full article

Cryptocurrencies are becoming increasingly prominent in financial investments, with more investors diversifying their portfolios and individuals drawn to their ease of use and decentralized financial opportunities. However, this accessibility also brings significant risks and rewards, often influenced by news and the sentiments of crypto investors, known as crypto signals. This paper explores the capabilities of large language models (LLMs) and natural language processing (NLP) models in analyzing sentiment from cryptocurrency-related news articles. We fine-tune state-of-the-art models such as GPT-4, BERT, and FinBERT for this specific task, evaluating their performance and comparing their effectiveness in sentiment classification. By leveraging these advanced techniques, we aim to enhance the understanding of sentiment dynamics in the cryptocurrency market, providing insights that can inform investment decisions and risk management strategies. The outcomes of this comparative study contribute to the broader discourse on applying advanced NLP models to cryptocurrency sentiment analysis, with implications for both academic research and practical applications in financial markets.
