Is ChatGPT a Viable Competitor to Domain-Specific Sentiment Analysis Machine Learning Models?
Introduction:
Welcome to an exciting exploration of ChatGPT, a revolutionary machine learning tool that has taken the world by storm. This GPT (Generative Pre-trained Transformer) has left both casual users and experts mesmerized with its remarkable capabilities. What’s particularly impressive about ChatGPT is its ability to excel in various tasks, from general domains to specific fields.
As a researcher, I am particularly intrigued by its application in sentiment analysis (SA), a popular branch of Natural Language Processing (NLP). SA has far-reaching applications across multiple domains, including finance, entertainment, and psychology. However, the use of specific terms and jargon in different fields poses an interesting question – can general domain ML models match the performance of domain-specific models?
In this article, we dive into this research question and compare ChatGPT to a domain-specific ML model. Drawing from the SemEval 2017 Task 5, a domain-specific sentiment analysis challenge, we evaluate the performance of ChatGPT in this specific task. Additionally, we explore how the ChatGPT API can be used to label datasets, providing code examples for better understanding.
Furthermore, we discuss the results of the comparison and delve into the reproducibility details, offering a comprehensive analysis of the findings. We also provide a discussion on the implications of this comparison in an applied scenario. Please note that this article aims to shed some light on the subject through a hands-on experiment and does not serve as an exhaustive scientific investigation.
Join me as we unravel the capabilities of ChatGPT and its relevance in sentiment analysis, offering insights into the fascinating world of AI research and industry applications.

ChatGPT, a Generative Pre-trained Transformer machine learning (ML) tool, has taken the world by storm with its impressive capabilities. It has garnered attention from casual users, professionals, researchers, and even its own creators. One specific area of interest for researchers like myself is the tool’s ability to perform sentiment analysis (SA), a widely used Natural Language Processing (NLP) technique.
SA has numerous applications and can be utilized in various domains such as finance, entertainment, and psychology. However, certain fields, like finance, have their own specific terms and jargon. This raises the question of whether general domain ML models can perform as well as domain-specific models in handling these specialized terms.
If you were to pose this research question to ChatGPT, the answer might surprise you. As an AI researcher, industry professional, and hobbyist, I am accustomed to fine-tuning general domain NLP machine learning tools, like GloVe, for specific tasks in different domains. This is because finding an out-of-the-box solution that performs well without any fine-tuning has historically been uncommon. However, ChatGPT may change that.
In this article, we will compare ChatGPT to a domain-specific ML model, focusing on the following topics:
1. SemEval 2017 Task 5 — A domain-specific challenge
SemEval is a well-known NLP workshop where research teams compete in sentiment analysis, text similarity, and question-answering tasks. The 2017 edition of SemEval included Task 5, which involved scoring financial microblogs and news headlines for sentiment analysis. To evaluate the performance of different solutions, the organizers provided gold-standard datasets created by domain specialists and linguists.
For our comparison, we will use the gold-standard dataset from the Subtask 2 of SemEval 2017 Task 5, which consisted of news headlines. The dataset was divided into training and testing sets, with the training set comprising 1,142 sentences and the testing set containing 491 sentences. An analysis of the data distribution revealed a bimodal distribution, with more positive sentences than negative ones.
2. Using ChatGPT API to label a dataset
To label the dataset, we utilized the ChatGPT API, which has been previously discussed for tasks such as data synthesis. Code examples for sentiment labeling using the ChatGPT API can be found in the API code samples section. However, please note that using the API comes at a cost.
To label multiple sentences at once, we prepared a prompt using a dataframe containing the gold-standard dataset. The prompt included the sentence to be labeled and the target company for the sentiment analysis. The ChatGPT API was then called using the text-davinci-003 engine. Adjustments were made to account for the maximum number of tokens allowed and the maximum length of the prompt and response.
The results of using the ChatGPT API to label the gold-standard dataset are shown in the article, with each sentence labeled for sentiment.
2.1. Issues with ChatGPT and its API at scale
Like any other API, the ChatGPT API has certain requirements and limitations. These include a request rate limit, a request limit for tokens, and a maximum length for requests. It is essential to be mindful of these requirements when working with the API.
In the context of this domain-specific problem, which involves sentiments related to specific target entities (companies), additional challenges were encountered. The prompt design had to account for the presence of a target entity in each sentence and make it easy to process the results. Moreover, when dealing with a large number of sentences, some inconsistencies, mismatches, and biases were observed in ChatGPT’s responses. These issues required fine-tuning and experimentation to achieve desired outcomes.
In summary, while ChatGPT offers impressive capabilities for sentiment analysis, it is important to be aware of its limitations and biases. Proper usage requires a learning curve, and the API may require adjustments to ensure accurate and consistent results.
Please note that this article presents a simple hands-on experiment rather than an exhaustive scientific investigation. The results provide valuable insights into the subject matter, but further research may be necessary for a comprehensive understanding of the topic.

Summary: Is ChatGPT a Viable Competitor to Domain-Specific Sentiment Analysis Machine Learning Models?
ChatGPT is a GPT (Generative Pre-trained Transformer) machine learning tool that has amazed users, professionals, and researchers alike. Its ability to excel in both general and domain-specific tasks is truly impressive. As a researcher, I am particularly interested in its performance in sentiment analysis (SA), which is a widely used natural language processing (NLP) technique. In this article, I compare ChatGPT to a domain-specific ML model using the SemEval 2017 Task 5 dataset. I also discuss the process of using ChatGPT API to label a dataset and highlight some issues and limitations encountered. Despite these challenges, the results obtained showcase the potential of ChatGPT in domain-specific tasks.
