Social media platforms have become influential in shaping public opinion, making it critical for political campaigns to understand the sentiment behind public discourse. In this study, social media data (e.g., tweets and posts) were collected and processed using Hadoop’s MapReduce framework to efficient handling large-scale data. Sentiment analysis was performed using a logistic regression model to classify public sentiment as positive, negative, or neutral. The model achieved an accuracy of 85%, with a precision of 0.86 for predicting a win and 0.84 for predicting a loss. Positive sentiment drivers such as "Viksit Bharat" and "stronger nation" had a strong positive impact on the likelihood of winning, while terms like "vote" and "voice" were associated with negative sentiment and a higher probability of losing. The study demonstrates that data-driven sentiment analysis can provide valuable insights for political strategists, enabling informed decision-making and improving campaign effectiveness.

INTRODUCTION In the digital era, social media platforms have become powerful tools for shaping public opinion and influencing political landscapes. Political leaders are increasingly using platforms like Twitter, Facebook, and YouTube to engage with voters, communicate policies, and build their public image. Simultaneously, the vast amount of unstructured data generated through user interactions—comments, likes, shares, and reactions—provides valuable insights into the sentiment and popularity of political figures. However, extracting meaningful information from such large-scale data presents significant challenges due to the high volume, velocity, and variety of data. Traditional data processing techniques often fail to handle this complexity effectively. Therefore, leveraging the Apache Hadoop framework, known for its distributed storage and parallel processing capabilities, becomes essential for efficient data mining and sentiment analysis of political leaders' popularity on social media. This approach enables real-time analysis, uncovering sentiment trends and public perception dynamics, which are crucial for strategic political decision-making. Despite the growing importance of social media in political discourse, there is a lack of systematic frameworks for efficiently processing and analyzing such data. Existing sentiment analysis techniques often struggle with scalability and accuracy when handling big data. Moreover, political sentiment is inherently complex, influenced by factors such as sarcasm, slang, and regional variations in language.

By integrating machine learning models for sentiment classification and trend prediction, this research aims to provide a comprehensive understanding of political leaders' popularity and public sentiment. Existing sentiment analysis techniques struggle to efficiently process and analyze the large volume, velocity, and variety of social media data related to political leaders. Traditional methods lack scalability and accuracy, making it difficult to extract meaningful insights and predict political popularity. In the era of digital transformation, social media has become a pivotal platform for public discourse, enabling individuals to express opinions, share information, and engage in political discussions. Platforms like Twitter, Facebook, and Instagram have revolutionized the way political leaders communicate with the public, offering realtime insights into their popularity and public perception. The massive volume of data generated on these platforms presents a unique opportunity to analyze public sentiment and evaluate the popularity of political figures. Sentiment analysis, a branch of natural language processing (NLP), plays a crucial role in extracting and interpreting emotions, opinions, and attitudes from textual data [1][2][3]. When combined with data mining techniques, it provides a powerful tool for uncovering patterns and trends in public sentiment [4]. Some research paper explores the efficient application of sentiment analysis and data mining to assess the popularity of political leaders on social media, utilizing the Apache Hadoop framework for scalable and distributed data processing [5][6][7]. The growing influence of social media on political landscapes has made it an indispensable tool for gauging public opinion [8]. Traditional methods, such as surveys and polls, are often limited by their scope, cost, and time constraints. In contrast, social media offers a vast, real-time, and cost-effective dataset that reflects diverse perspectives from a wide demographic. However, the sheer volume and complexity of social media data pose significant challenges for analysis. Sentiment analysis addresses these challenges by classifying text into positive, negative, or neutral categories, providing a quantitative measure of public sentiment [1]. Despite its potential, sentiment analysis faces hurdles such as sarcasm, irony, and context-dependent meanings, which can affect accuracy [3]. Data mining complements sentiment analysis by identifying patterns, correlations, and trends in the data, enabling a deeper understanding of public opinion [9]. The Apache Hadoop framework, an opensource platform for distributed storage and processing of big data, offers a scalable solution for handling the challenges posed by social media data [5]. Its core components, the Hadoop Distributed File System (HDFS) and the MapReduce programming model, enable efficient processing of large datasets across clusters of computers [2]. HDFS provides fault-tolerant storage, while MapReduce facilitates parallel data processing, making Hadoop ideal for big data applications. By leveraging Hadoop's distributed architecture, researchers can preprocess, analyze, and visualize social media data at scale, overcoming the limitations of traditional data processing systems [5]. This research paper proposes an efficient approach to evaluating the popularity of political leaders on social media by integrating sentiment analysis, data mining, and the Apache Hadoop framework. The study aims to address the challenges of analyzing large-scale social media data while providing accurate and actionable insights into public sentiment. By analyzing tweets and other social media posts, the proposed approach can identify trends, track changes in sentiment over time, and assess the impact of specific events on political leaders' popularity [10]. This paper aims to develop an efficient framework using Apache Hadoop to handle big data challenges, classify sentiment accurately, and provide real-time insights into political leaders' public perception.

LITERATURE SURVEY The field of sentiment analysis and data mining has undergone significant transformation over the past three decades, evolving in tandem with advancements in computational technologies and the exponential growth of digital data. This section systematically reviews this evolution through distinct chronological phases, highlighting key technological breakthroughs and their applications in political sentiment analysis. 2.1 Early Foundations (Pre-2000) The foundational period of sentiment analysis and data mining was characterized by basic lexiconbased approaches and limited computational capabilities. Researchers primarily relied on predefined word lists containing positive and negative sentiment indicators to perform text classification [1]. Data mining techniques during this era, including clustering and classification algorithms, were predominantly applied to structured datasets in commercial domains such as market research and customer relationship management [10]. However, these methods proved inadequate for handling the volume and complexity of unstructured data that would later emerge through social media platforms. 2.2 Machine Learning Revolution (2000-2006) The turn of the century marked a paradigm shift with the introduction of machine learning techniques for sentiment analysis. Pang et al.'s (2002) seminal work demonstrated the effectiveness of Naive Bayes and Support Vector Machines (SVMs) in analyzing sentiment within movie reviews, establishing machine learning as a superior alternative to lexiconbased methods [4]. Concurrently, data mining witnessed substantial progress through the adoption of association rule mining and decision tree algorithms, enabling more sophisticated pattern recognition in large datasets [9]. This period coincided with the emergence of major social media platforms, including Facebook (2004) and Twitter (2006), which presented both new challenges and opportunities for sentiment analysis due to their unique linguistic characteristics (slang, abbreviations, emoticons) and unprecedented data volumes [1]. 2.3 Big Data Era (2006-2010) The introduction of Apache Hadoop in 2006 by Cutting and Cafarella revolutionized data processing capabilities [5]. Hadoop's distributed file system (HDFS) and MapReduce programming model provided the first scalable framework for storing and processing massive social media datasets. This technological breakthrough enabled researchers to overcome previous limitations in handling unstructured data, making comprehensive social media analytics feasible for the first time. During this period, O'Connor et al. (2010) demonstrated the potential of Twitter data as a real-time indicator of public sentiment by correlating social media analysis with traditional political opinion polls [10]. 2.4 Deep Learning Integration (2010-2020) The subsequent decade witnessed remarkable advancements through the integration of deep learning architectures with big data frameworks. Recurrent Neural Networks (RNNs) and Convolutional Neural Networks (CNNs) significantly improved sentiment classification accuracy by capturing contextual relationships in text data [11]. The Hadoop ecosystem expanded through integration with complementary tools like Apache Spark (for real-time processing) and Apache Hive (for data warehousing), creating comprehensive solutions for social media analytics [5]. These technological synergies enabled more sophisticated applications, particularly in political sentiment analysis, where researchers began developing predictive models for election outcomes based on social media data.

No.11 © Little Lion Scientific ISSN: 1992-8645 www.jatit.org E-ISSN: 1817-3195 4832 2.5 Contemporary Developments (2020-Present) Recent years have seen the convergence of artificial intelligence (AI) and natural language processing (NLP) with big data frameworks, pushing the boundaries of sentiment analysis capabilities [11][12][13]. Transformer-based models like BERT and GPT have demonstrated exceptional performance in understanding nuanced political sentiment across social media platforms [12]. The integration of these advanced NLP techniques with Hadoop-based architectures has created powerful systems for real-time monitoring and prediction of political trends [14][15]. Current research focuses on overcoming remaining challenges such as sarcasm detection, multilingual analysis, and the ethical implications of predictive political analytics. Table 1 summarizes this evolutionary trajectory, highlighting how each technological breakthrough has enhanced the capacity to analyze political sentiment at scale. The progression from simple lexicon-based methods to contemporary AI-driven approaches reflects both the growing complexity of social media data and the corresponding advancements in analytical methodologies.

PROBLEM FORMULATION The problem addressed in this research is the challenge of accurately predicting election outcomes based on voter sentiment analysis of social media data. Political campaigns generate vast amounts of data through social media interactions, reflecting public perception of candidates and campaign messages. However, effectively extracting and interpreting this data to identify the factors influencing electoral success remains a complex task. Existing models often struggle to distinguish between influential and non-influential factors, particularly when dealing with high-dimensional, unstructured data. Additionally, the impact of positive and negative campaign messaging on voter behavior is not well understood. While themes related to development and national strength, such as "Viksit Bharat" and "stronger nation," have shown a strong positive correlation with winning outcomes, themes like "vote" and "voice" are linked to higher chances of losing, possibly due to voter fatigue or lack of substantive content. The challenge lies in developing a robust, scalable framework that can accurately classify voter sentiment, identify high-impact keywords, and provide actionable insights for optimizing campaign strategies. This research aims to address these gaps by proposing a machine learning-based sentiment analysis model using the Apache Hadoop framework, focusing on improving predictive accuracy and understanding the nuanced impact of positive and negative messaging on electoral outcomes. 4. DATA COLLECTION For the research paper, data collection involves gathering 20 social media messages (e.g., tweets, Facebook posts) each for political leaders who won and lost the LokSabha 2024 elections [26][27]. The data is sourced from platforms like Twitter and Facebook, focusing on public posts and comments reflecting public sentiment. These messages are collected using APIs or web scraping tools, ensuring they are relevant to the election context. The dataset is then pre-processed (e.g., removing duplicates, handling noise) and stored in the Hadoop Distributed File System (HDFS) for efficient processing. This structured approach ensures a balanced dataset for sentiment analysis and data mining using the Apache Hadoop framework [28][29][30].

PROPOSED METHODOLOGY Here we applied Sentiment Analysis and Data Mining Using Hadoop methodology in our collected data. We show the flow of data with the help of Figure 2. Figure 2 shows the process of sentiment analysis and data mining using Hadoop to predict election outcomes. It starts with collecting social media data (e.g., Tweets, Facebook posts) via APIs or web scraping, storing it in Hadoop Distributed File System (HDFS). The data is pre-processed by cleaning, tokenizing, and filtering for relevant keywords. Sentiment analysis classifies each post/tweet using a pre-trained model, assigning sentiment scores (Positive, Negative, Neutral). Hadoop’s Map Reduce phase processes the data: the mapper emits (keyword, sentiment score) pairs and the reducer aggregates scores for trend analysis over time. A machine learning model (e.g., Logistic Regression) is trained on historical data to predict election outcomes. Finally, insights are visualized through charts or dashboards for interpretation.

EXPERIMENTAL RESULTS AND ANALYSIS The proposed framework employs the Apache Hadoop ecosystem for distributed data processing and machine learning-based sentiment analysis. Social media data related to political campaigns were collected and processed using Hadoop Distributed File System (HDFS) and MapReduce. Sentiment classification was performed using a logistic regression model trained on labeled datasets. The model classified sentiments into three categories: Positive, Negative, and Neutral. Feature extraction involved keyword analysis, where the frequency and contextual relevance of keywords were assessed to enhance prediction accuracy. The model's performance was evaluated using standard metrics such as accuracy, precision, recall, and F1score. Weighted models were also tested to determine the impact of strategic keyword emphasis on prediction accuracy. 6.1 SENTIMENT DISTRIBUTION Figure 3 presents the overall sentiment distribution extracted from social media data related to election campaigns. Positive sentiment accounted for 60% of the total data, indicating that campaign messages were generally well-received by the public. Negative sentiment represented 25%, reflecting criticism or opposition, while neutral sentiment stood at 15%, showing mixed or indifferent opinions. Figure 3, a pie chart, visually illustrates this distribution, reinforcing the conclusion that public perception of the campaigns was predominantly favorable.
