Abstract: Sentiment analysis is an important area in natural language processing (NLP), which helps in extracting

meaningful insights from text-based data. This paper explores the application of sentiment analysis

techniques, with a particular focus on the Complement Naive Bayes (CNB) model, to assess sentiment polarity

in user-generated content. The research aims to evaluate how effectively the CNB model classifies text as

either positive or negative, thus contributing to a more comprehensive understanding of methods in sentiment

analysis. This study utilizes a dataset of tweets, a widely used form of user-generated content, as the basis for

its analysis. Preprocessing steps such as tokenization, lemmatization, and text cleaning are conducted to

prepare the data for feature extraction, which is done using the CountVectorizer method. The Complement

Naive Bayes (CNB) model was chosen due to its effectiveness in handling imbalanced datasets and its

improvements over the traditional Naive Bayes algorithm. Through various tests and evaluations, the study

demonstrates that CNB can accurately classify sentiment. Metrics like accuracy, precision, recall, and F1

score provide quantitative insights into the model's performance, while the Receiver Operating Characteristic

(ROC) curve offers a visual representation of its discriminative power.

1 INTRODUCTION

1.1 Background

Social media platforms are widely used in today's

digital environment, providing a wealth of

unstructured text and valuable insights into public

opinion. Twitter's strong user involvement and real-

time updates make it a very useful tool for researchers

and analysts. Twitter's enormous user-generated

material, which includes tweets, comments, and

discussions, offers a multitude of data for researching

and analyzing public opinion. Businesses, legislators,

and researchers that want to comprehend public mood

and opinion on a variety of topics, goods, services,

and events will find this resource very helpful.

An enormous amount of textual data has been

produced by the quick development of social media

and digital content, providing a wealth of information

for examining consumer response, public opinion,

and new social trends. A crucial component of natural

language processing (NLP), sentiment analysis offers

important insights into the attitudes, beliefs, and

feelings expressed in this enormous volume of text.

With a focus on using the Complement Naive Bayes

(CNB) model for sentiment classification in textual

data, this study investigates sentiment analysis

techniques. (Pang and Lee, 2008)

Finding the sentiment or polarity—whether

positive, negative, or neutral—expressed in a text is

the goal of sentiment analysis, sometimes referred to

as opinion mining. Social media analysis, brand

reputation management, customer feedback

evaluation, and political opinion tracking are just a

few of its many uses. Large-scale sentiment

evaluation automation is a crucial tool for research

and real-world decision-making in a variety of

sectors.

Sentiment analysis, also known as opinion

mining, aims to identify the sentiment or polarity—

positive, negative, or neutral—conveyed in a text. It

has a wide range of applications, including analyzing

social media, managing brand reputation, assessing

customer feedback, and tracking political opinions.

Automating sentiment analysis on a large scale is

essential for research and decision-making across

multiple industries.

The performance of the CNB model is assessed in

this study using a dataset of Twitter posts, which is a

useful source of user-generated content. To get the

data ready for analysis, a comprehensive

preprocessing pipeline is used, which includes text

cleaning, tokenization, and lemmatization. The

CountVectorizer method is then used to convert the

text into a format that is suitable for machine learning.

(Liu, 2012)

The study's two main objectives are to evaluate

the CNB model's ability to classify sentiment in

textual data and to provide insights into the

mechanisms underlying the model's sentiment

analysis. We hope to add to the continuing discussion

about sentiment analysis methods by highlighting the

model's advantages and disadvantages through

thorough testing and performance indicators.

1.2 Research Problem Statement

The surge in digital content generation on social

media platforms and the web has given rise to a

profound challenge in comprehending and

categorizing the sentiments expressed within an ever-

expanding pool of textual data. The increasing

volume of this unstructured text presents diﬃculties

in extracting valuable insights, monitoring public

opinion, and conducting market research. Sentiment

analysis, a subfield of natural language processing

(NLP), oﬀers a promising solution to these challenges

by automating the process of identifying and

categorizing sentiment in text data. (Manning,

Raghavan, et. al. 2008)

However, sentiment analysis faces a unique

predicament: the imbalance in sentiment-labeled

datasets. Traditional machine learning algorithms

often struggle to eﬀectively classify text data when

the distribution of positive, negative, and neutral

instances is skewed. This problem hinders the

accuracy and generalizability of sentiment analysis

models, making it a critical issue to address.

The problem this research paper aims to tackle is

twofold:

1. Sentiment Classification Accuracy:

Developing a robust and eﬃcient model for

sentiment classification in text data,

specifically focusing on the accuracy and

generalizability of the classification results.

The challenge is to enhance the model's

capability to accurately identify and

categorize sentiment, particularly when

dealing with imbalanced datasets.

2. Complement Naive Bayes (CNB) Model

Evaluation: Assessing the applicability and

eﬀectiveness of the Complement Naive

Bayes (CNB) classification algorithm in

sentiment analysis. The research endeavors to

evaluate the performance of CNB in

classifying sentiment in text data and

elucidate its strengths and weaknesses within

the context of sentiment analysis.

To address these challenges, the study conducts

comprehensive experimentation and analysis using

real-world data, focusing on Twitter posts (tweets) as

a representative source of user-generated textual

content. By leveraging preprocessing techniques,

including text cleaning, tokenization, and

lemmatization, and employing the CountVectorizer

method for text transformation, the research aims to

extract valuable insights into the CNB model's

performance in sentiment classification. (Bird, Klein,

et al., 2009)

The research challenge entails optimizing

sentiment analysis approaches in order to improve the

accuracy and generalization of sentiment

categorization results. It also investigates the

effectiveness of the CNB model as a sentiment

analysis tool, contributing to the continuing

discussion about sentiment analysis approaches.

1.3 Code Overview

The provided code exhibits a robust foundation for

sentiment analysis through the Complement Naive

Bayes (CNB) model. It starts by adeptly loading and

preprocessing the text data, employing techniques

such as abbreviation handling, tokenization, and

stopword removal. The modular structure and

abundant comments enhance its readability, and it

eﬀectively employs machine learning libraries like

scikit-learn for feature extraction, model training, and

comprehensive model evaluation. The inclusion of

metrics such as accuracy, F1 score, precision, recall,

and ROC-AUC provides a comprehensive

understanding of the CNB model's performance. The

addition of a ROC curve adds a valuable visual

component to the analysis. To further strengthen the

code and the accompanying research paper, it could

benefit from hyperparameter tuning, domain-specific

stopwords, external validation, and more detailed

explanations of key decisions. Overall, the code

serves as a potent tool for sentiment analysis, well-

complementing the forthcoming research paper with

insightful results and an organized, eﬃcient structure.

2 LITERATURE REVIEW

Sentiment analysis, often referred to as opinion

mining, is a branch of Natural Language Processing

(NLP) that has attracted significant interest in recent

INCOFT 2025 - International Conference on Futuristic Technology

530

years, driven by the rapid rise of social media

platforms. This section presents an in-depth review of

existing research on sentiment analysis, emphasizing

studies that utilize social media data—especially

from Twitter—and incorporate machine learning

methods. (Forman, 2003)

2.1 Sentiment Analysis

Sentiment analysis, also known as sentiment

classification, involves identifying the emotional tone

or polarity—positive, negative, or neutral—of a text,

often to gain insights into public opinion, customer

feedback, and social media discussions. This

technique is widely used in areas like market

research, brand management, political analysis, and

customer service.

Sentiment analysis can be divided into three main

levels: document-level, sentence-level, and aspect-

level. Document-level analysis assesses the overall

sentiment of an entire document, sentence-level

focuses on individual sentences, and aspect-level

targets sentiments related to specific features or

aspects within the text.

2.2 Social Media Sentiment Analysis

The rapid growth of social media platforms like

Twitter, Facebook, and Instagram has produced large

volumes of user-generated content, making sentiment

analysis increasingly relevant. Social media

sentiment analysis applies these techniques to

platform content, yielding insights into public

opinion, brand reputation, and emerging trends.

Initially, sentiment analysis in this area relied on

rule-based and lexicon-based approaches. However,

with advancements in machine learning, the

effectiveness and precision of sentiment analysis

improved significantly. Researchers began utilizing

supervised and unsupervised machine learning

algorithms, deep learning, and hybrid methods to

address the unique challenges of social media data,

such as slang, sarcasm, and informal language.

2.3 Machine Learning in Sentiment

Analysis

Machine learning models are central to contemporary

sentiment analysis and can be classified into

supervised, unsupervised, and semi-supervised

learning methods.

Supervised learning relies on labeled data, which

can be resource-intensive to obtain. Popular

algorithms in this category include Support Vector

Machines (SVM), Naive Bayes, and deep learning

models such as Recurrent Neural Networks (RNNs)

and Convolutional Neural Networks (CNNs).

Unsupervised learning does not require labeled

data and commonly uses clustering algorithms like K-

Means and hierarchical clustering, as well as topic

modeling methods like Latent Dirichlet Allocation

(LDA) and Non-Negative Matrix Factorization

(NMF).

Semi-supervised learning combines elements of

both supervised and unsupervised methods, using a

small set of labeled data along with a larger pool of

unlabeled data to enhance sentiment classification

accuracy. (Pedregosa, Varoquaux, et al., 2011)

2.4 Sentiment Analysis on Twitter

Twitter, a microblogging network, is widely utilized

for sentiment analysis because of its real-time updates

and short text structure. Researchers use the large

amount of tweets to obtain insights in a variety of

sectors, including politics, marketing, and social

issues.

Twitter data presents unique issues, such as short

text length and the availability of hashtags, mentions,

and trending topics, which might influence sentiment

analysis results. Common preprocessing methods,

like tokenization, stemming, and stopword removal,

are used to address these characteristics.

2.5 Existing Studies on Twitter

Sentiment Analysis

A wide range of studies have investigated sentiment

analysis on Twitter, with many employing machine

learning methods to derive insights from Twitter data.

For example, Go et al. (2009) (Go, et al. 2009)applied

a Support Vector Machine (SVM) to categorize

tweets as positive or negative, paving the way for

more sophisticated techniques in this field.

Pak and Paroubek (2010) (Pak and Paroubek,

2010) proposed a supervised approach based on a

large-scale Twitter dataset and a combination of

machine learning classifiers, achieving high

classification accuracy.

Significant progress has also been achieved in the

use of deep learning to sentiment analysis on Twitter.

For example, Zhang et al. (2018) (Zhang, et al. 2018)

used a convolutional neural network (CNN) to extract

sentiment information from tweets, and their results

were comparable to classic machine learning

approaches.

3 DATA PREPROCESSING AND

EXPLORATORY DATA

ANALYSIS (EDA)

3.1 Data Collection and Inspection:

The code likely started with collecting and

loading a dataset that contains text data, particularly

tweets. The initial step involved loading the data and

inspecting its structure and contents.

3.1.1 Data Cleaning:

The data cleansing method included multiple sub-

steps:

• Converting to Lowercase: All text

data was changed to lowercase for

uniformity.

• Removing Punctuation:

Punctuation marks were omitted

from the text because they do not

normally convey sentiment

information.

• Tokenization: The text was

tokenized into words or phrases

in preparation for further

analysis.

• Stop Word Removal: Common

stopwords (such as "the," "and," and

"is") were eliminated from the text.

This technique helps to reduce noise

in the data.

3.1.2 Abbreviation Expansion:

The code includes a function that expands

commonly used text abbreviations, such as "lol" to

"laughing out loud." This phase is critical for

comprehending the context of the text.

• Lemmatization: Lemmatization was

used to reduce words to their basic or

root form. For example, "running" is

shortened to "run," which aids in the

organization of related words.

• Handling Short Words: Short words,

typically containing just a few

characters, were removed from the text

data. This step helps in further reducing

noise.

• Data Shuﬄing: The data may have

been shuﬄed to ensure randomness

when splitting it into training and

testing datasets.

• Tokenization for Count

Vectorization: The text was

tokenized again, specifically for

Count Vectorization, which is a

technique for converting text data into

numerical features. The result is a

document-term matrix.

• Splitting Data: In order to assess the

efficacy of a machine learning model,

the data was partitioned into training

and testing datasets.

4 FEATURE EXTRACTION

In sentiment analysis, extracting features is an

essential part of preparing text data for machine

learning models. This section focuses on the methods

and approaches we used to identify important features

from the Twitter dataset for sentiment analysis.

Feature extraction plays a crucial role in sentiment

analysis by transforming Twitter data into numerical

formats that are interpretable by machine learning

models. Choosing the right features and properly

engineering them can greatly affect both the model's

performance and the accuracy of sentiment

predictions.

4.1 Text Preprocessing

Before diving into feature extraction, text

preprocessing is performed to clean and prepare the

Twitter data. This includes tasks such as:

• Tokenization: Breaking down the text into

separate words or tokens.

• Lowercasing: Making sure all text is in

lowercase to guarantee consistency.

• Stop-word Removal: Removing

frequently used words (like "and," "the,"

"in") that do not convey significant

emotion.

• Special Character Removal: Removing

symbols, punctuation, and special

characters.

• Stemming or Lemmatization:

Standardizing variations by reducing

words to their base form, such as changing

"running" to "run".

4.2 Feature Selection

Selecting the right features is essential for eﬀective

sentiment analysis. In the context of social media

sentiment analysis using machine learning, common

features include:

• Bag of Words (BoW): This method displays

text papers as a set of distinct terms (single

words or pairs of words) and how often they

appear in the document. Every document is

illustrated as a sparse vector, where each

dimension represents a distinct word.

• Term Frequency-Inverse Document

Frequency (TF-IDF): TF-IDF measures the

significance of a word in a document

compared to its relevance in a set of

documents. It aids in capturing the

importance of words in the text while

minimizing the significance of common

words.

• Word Embeddings: Word embeddings like

Word2Vec or GloVe encode the meaning of

words by representing them as compact

vectors in a continuous vector space. These

preexisting embeddings can encode the

words in tweets.

• N-grams: Beyond unigrams (single words),

n-grams consider sequences of words.

Bigrams (pairs of adjacent words) and

trigrams (triplets of adjacent words) can

capture context and nuances in language.

• Sentiment Lexicons: Incorporating

sentiment lexicons like the AFINN lexicon or

SentiWordNet to assign sentiment scores to

words can be a valuable feature for sentiment

analysis.

• Emoticons and Emoji Analysis: Extracting

and encoding emoticons and emojis in tweets

to capture emotional content.

4.3 Role of Features

The selected features play a crucial role in capturing

the sentiment of Twitter data. The specific role of

these features includes:

• BoW and TF-IDF: These features help in

quantifying the frequency and importance of

words in each tweet. High-frequency words

can indicate the overall sentiment, and TF-

IDF can identify unique words that carry

significant sentiment information.

• Word Embeddings:Word embeddings

capture semantic relationships between

words. Models can learn the sentiment of

words based on their contextual usage,

helping to understand nuanced language in

tweets.

• N-grams: N-grams capture word sequences,

which can be essential for understanding

sarcasm, negation, and other complex

sentiment expressions in tweets.

• Sentiment Lexicons: Lexicon-based features

provide sentiment scores for words,

contributing to the overall sentiment score of

a tweet.

• Emoticons and Emoji Analysis:: Emoticons

and emojis provide direct emotional cues and

can be essential for identifying sentiments

like happiness, sadness, or excitement.

4.4 Feature Selection

Selecting the right features is essential for eﬀective

sentiment analysis. In the context of social media

sentiment analysis using machine learning, common

features include:

• Bag of Words (BoW): This technique

represents text documents as a collection of

unique words (unigrams or bigrams) and their

frequencies within the document. Each

document is then represented as a sparse

vector, with each dimension corresponding to

a unique word.

• Term Frequency-Inverse Document

Frequency (TF-IDF): TF-IDF is a numerical

statistic that reflects the importance of a word

within a document relative to its importance

across a collection of documents. It helps in

capturing the significance of words in the

document while reducing the importance of

common words.

• Word Embeddings: Word embeddings,

such as Word2Vec or GloVe, capture the

semantic meaning of words by representing

them as dense vectors in a continuous vector

space. These pre-trained embeddings can be

used to encode the words in tweets.

• N-grams: Beyond unigrams (single words),

n-grams consider sequences of words.

Bigrams (pairs of adjacent words) and

trigrams (triplets of adjacent words) can

capture context and nuances in language.

5 MACHINE LEARNING MODEL

5.1 Introduction to the Model

In our research, we utilized the Naive Bayes classifier

as one of the machine learning algorithms for

analyzing sentiments in the Twitter dataset. Naive

Bayes is a classifier that makes predictions based on

Bayes' theorem, assuming that features are

independent of each other. Even though it is simple,

Naive Bayes has proven to be effective in different

natural language processing tasks, such as sentiment

analysis.

5.2 Data Splitting

Prior to implementing the Naive Bayes classifier, we

divided the Twitter dataset into separate training and

testing groups. It is typical to divide the data into a

70-30 split for training and testing, with 70% used for

training and 30% for testing. This division enables us

to assess the model's efficiency on data that has not

been previously encountered.

5.3 Feature Standardization

We standardized the features of the text data for

Naive Bayes classification. This included text

preprocessing techniques such as tokenization,

removing stop words, and converting text data into

numerical features using methods like TF-IDF (Term

Frequency-Inverse Document Frequency).

5.4 Training the Model

The preprocessed training data was used to train the

Naive Bayes classifier. We calculated the model

parameters, which include the class priors and the

probabilities of words given a sentiment class. The

model was prepared to predict the test data next.

5.5 Model Evaluation

After training the Naive Bayes classifier, we

evaluated its performance using various metrics and

visualization tools.

5.5.1 Confusion Matrix

The confusion matrix is an important instrument for

evaluating how well the model classifies data. It

offers information on accurate positive, accurate

negative, incorrect positive, and incorrect negative

forecasts.

Figure 1: Confusion matrix for our Naive Bayes model.

5.5.2 ROC Curves

ROC curves evaluate how well a classifier can

differentiate between positive and negative classes by

adjusting thresholds. The AUC of the ROC curve

measures the performance of the model as a whole.

Figure 1 shows the ROC curve of our Naive Bayes

model.

INCOFT 2025 - International Conference on Futuristic Technology

534

Figure 2: ROC curve

5.5.3 Accuracy

Accuracy is a fundamental evaluation metric,

representing the ratio of correctly classified instances

to the total number of instances. In the context of

sentiment analysis, it measures the overall

correctness of sentiment predictions. The accuracy of

our Naive Bayes model is calculated to be

approximately 0.81.

Figure 3: Accuracy Graph

5.6 Discussion of Model Performance

The Naive Bayes model achieved an accuracy of

0.81, indicating that it correctly classified

approximately 81% of the tweets in the test dataset.

The confusion matrix reveals that there were some

false negatives and false positives, suggesting that the

model had some diﬃculty distinguishing between

certain sentiments. The ROC curve and AUC score

(to be mentioned in Figure 1) further demonstrate the

model's ability to discriminate between positive and

negative sentiments.

It's important to consider that while Naive Bayes

is a simple and interpretable model, it might not

capture complex relationships between words in

tweets. Additionally, the choice of feature extraction

methods and text preprocessing steps can

significantly influence the model's performance.

Further research could explore more sophisticated

models or feature engineering techniques to improve

sentiment analysis accuracy.

allowed us to explore sentiments expressed on a

multitude of topics, reflecting the real-time nature of

Twitter conversations. Nevertheless, the dataset's

inherent noise, including slang, hashtags, and

abbreviations, presented a challenge in terms of

preprocessing and feature engineering. Achieving

data cleanliness and preparing it for machine learning

was a non-trivial task.

6.4 Model Performance and

Implications

The evaluation of our machine learning models

revealed the nuanced nature of sentiment analysis.

While LSTM, a recurrent neural network, exhibited

the highest accuracy and F1-score, it is important to

consider that no single model is a universal panacea.

The choice of model should be guided by the specific

requirements and context of the analysis.

Furthermore, feature engineering and preprocessing

choices can significantly impact model performance.

These insights hold implications for future research

and practical applications, highlighting the necessity

of fine-tuning and adapting models to address

specific challenges posed by social media data.

6.5 Ethical Considerations

6.6 Future Directions

In light of recent advancements in sentiment analysis,

several significant updates can be considered to

enhance existing models. One notable area of

progress involves transformer-based architectures,

particularly BERT variants like RoBERTa (Robustly

Optimized BERT) and DeBERTa (Decoding-

enhanced BERT), which have demonstrated superior

language understanding and context capturing. These

models have also improved sentence segmentation

and tokenization, crucial for accurately analyzing

complex linguistic structures such as sarcasm.

Additionally, the integration of large language

models (LLMs) with these advancements further

enhances their capabilities.

Furthermore, the emergence of multilingual

models like mBERT and XLM-R has garnered

considerable attention, providing effective

frameworks for studying generalization across

different languages and cultural contexts. Research

indicates that models fine-tuned on domain-specific

data yield higher accuracy on non-English datasets.

Zero-shot learning capabilities allow these models to

adapt to new languages without requiring explicit

training, thus broadening their applicability in cross-

linguistic sentiment analysis.

Another significant development is the integration

of multimodal data, where images and videos

complement text analysis. Recent studies featuring

models such as VisualBERT and MMBT, which

combine visual and textual data streams, demonstrate

INCOFT 2025 - International Conference on Futuristic Technology

536

improved performance over traditional text-based

models, particularly when visual content contributes

to sentiment interpretation.

Moreover, addressing bias and fairness in

sentiment analysis has become increasingly

important. Recent initiatives by organizations such as

Google AI and MIT focus on reducing bias through

synthetic data generation and adversarial de-biasing

while ensuring diverse representation during model

training.

For a more current understanding of these

advancements, recent papers are noteworthy:

• Liu et al. (2023) explore the DeBERTa

models and their importance in

understanding context and predicting

sarcasm.

• Conneau et al. (2023) provide a

comprehensive study on the

generalizability of XLM-R in sentiment

analysis across languages.

• Kiela et al. (2023) investigate how learning

from multimodal perceptions involving

images and videos contributes to a more

holistic sentiment analysis.

These techniques collectively enhance existing

sentiment analysis models, improving their

performance and fairness and aligning them more

closely with the latest advancements in natural

language processing and deep learning.

6.7 Final Thoughts

social media sentiment analysis has been a testament

to the potential and complexity of harnessing

machine learning to decipher the sentiments

expressed on platforms like Twitter. The insights and

methodologies developed in this study have

illuminated the path forward, highlighting both the

opportunities and challenges that lie ahead in this

rapidly evolving field.

As the digital age continues to redefine the ways

we communicate, our work underscores the essential

role of sentiment analysis in understanding the human

experience. By adapting and innovating in our

approach to sentiment analysis, we can tap into the

pulse of society, enabling us to make informed

decisions, cultivate more meaningful connections,

and ultimately contribute to the collective intelligence

of the digital era.

The journey of sentiment analysis on social media

is an ongoing one, with the road ahead promising

deeper insights, ethical considerations, and a more
