Twitter has become a key element of political discourse in candidates’ campaigns. The political polarization on Twitter is vital to politicians as it is a popular public medium to analyze and predict public opinion concerning political events. The analysis of the sentiment of political tweet contents mainly depends on the quality of sentiment lexicons. Therefore, it is crucial to create sentiment lexicons of the highest quality. In the proposed system, the domain-specific of the political lexicon is constructed by using the supervised approach to extract extreme political opinions words, and features in tweets. Political multi-class sentiment analysis (PMSA) system on the big data platform is developed to predict the inclination of tweets to infer the results of the elections by conducting the analysis on different political datasets: including the Trump election dataset and the BBC News politics. The comparative analysis is the experimental results which are better political text classification by using the three different models (multinomial naïve Bayes (MNB), decision tree (DT), linear support vector classification (SVC)). In the comparison of three different models, linear SVC has the better performance than the other two techniques. The analytical evaluation results show that the proposed system can be performed with 98% accuracy in linear SVC.

Insights to Problems, Research Trend and Progress in Techniques of Sentiment ...IJECEIAES
The research-based implementations towards Sentiment analyses are about a decade old and have introduced many significant algorithms, techniques, and framework towards enhancing its performance. The applicability of sentiment analysis towards business and the political survey is quite immense. However, we strongly feel that existing progress in research towards Sentiment Analysis is not at par with the demand of massively increasing dynamic data over the pervasive environment. The degree of problems associated with opinion mining over such forms of data has been less addressed, and still, it leaves the certain major scope of research. This paper will brief about existing research trends, some important research implementation in recent times, and exploring some major open issues about sentiment analysis. We believe that this manuscript will give a progress report with the snapshot of effectiveness borne by the research techniques towards sentiment analysis to further assist the upcoming researcher to identify and pave their research work in a perfect direction towards considering research gap.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

1. INTRODUCTION
Sentiment analysis has emerged as a critical field of research within Artificial Intelligence (AI),
finding diverse applications in politics, social media, and market research [1]. The ability to
capture and analyze public sentiment provides invaluable insights into individuals' opinions,
attitudes, and emotions, empowering organizations and policymakers to make informed
decisions. Among the plethora of social platforms, Twitter stands out as a prominent source of
real-time, user-generated data reflecting public sentiment [2].
The Indian political landscape is a dynamic and vibrant arena where local sentiments play a
pivotal role in shaping electoral outcomes [3]. In this context, sentiment analysis of political
discourse on Twitter has proven to be a powerful tool for understanding public opinion,
predicting election results, and devising effective political strategies, especially in Western
elections [4].
Karnataka, located in the southern region of the Indian subcontinent, is a state known for its
linguistic diversity, with over 150 languages spoken throughout its territory. The quinquennial
Karnataka state elections held in May 2023 provide an ideal case study to explore the sentiment
dynamics and predictive capabilities of Natural Language Processing (NLP) classification.
This paper aims to present a comprehensive analysis of sentiment on Twitter regarding the
Karnataka elections, offering valuable insights into the sentiment dynamics leading to the victory
of the Indian National Congress (INC) and the defeat of the current ruling party, Bharatiya

Janata Party (BJP). Prior to the elections, the state was long under the control of the local
Janata Dal (Secular) (JDS) party, followed by becoming a regional stronghold of theBJP in South
India. Given the BJP's defeats in multiple other local elections throughout India, especially in the
South, failure to win Karnataka in the 2023 state elections would be a significant setback for the
ruling party. Such a loss could further impact the party's efforts in the upcoming national
elections, Lok Sabha 2024, where the BJP seeks to maintain its status as the ruling national party.
Leveraging advancements in transformer-based models, specifically designed for sentiment
analysis in Indic languages [5], this study contributes to the growing body of literature on
sentiment analysis and political forecasting, focusing on the Indian political system. To achieve
our research objectives, we adopted a multi-faceted approach that involved innovative data
collection techniques, advanced transformer architectures, and targeted modeloptimization. Our
methodology included web scraping to collect a diverse range of tweets, ensuring a
representative sample of sentiments expressed in the period leading up to the election. To
augment the dataset, we employed multiple data augmentation techniques to enhance its diversity
and generalizability.
Building upon the success of transformer-based models in various natural language processing
tasks [6], we utilized state-of-the-art architectures specifically tailored for sentiment analysis in
Indic languages. The selected models, such as BERT [7] and IndicBERT [8], are known for
their ability to capture semantic nuances, contextual information, and linguistic patterns inherent
in Indian languages, making them highly suitable for analyzing sentiment in the context of
Karnataka elections.
The significance of this research lies in its potential to provide political parties with timely and
accurate insights into public sentiment, facilitating informed decision-making and strategic
planning for the forthcoming 2024 Lok Sabha elections. By leveraging the power of NLP and
sentiment analysis, political actors can gauge the effectiveness of their campaigns, identify
potential voter concerns, and tailor their messaging to align with the prevailing sentiment [9].
This paper is structured as follows: Section 2 provides a comprehensive review of related work
in sentiment analysis, political forecasting, and the use of Twitter data in analyzing public
sentiment. Section 3 details the dataset collection process, including web scraping and data
augmentation techniques employed. Section 4 presents the methodology, encompassing the
transformer-based models, hyperparameter tuning, and evaluation metrics. Section 5presents the
experimental results and analyses, highlighting the accuracy achieved in predicting the sentiment
towards the BJP's defeat or the INC's victory. Finally, Section 6 concludes the paper and
discusses avenues for future research.
2. LITERATURE REVIEW
2.1. Machine Learning for Sentiment Classification
Machine learning algorithms, such as Support Vector Machines (SVM), Naive Bayes, and
Maximum Entropy, have been widely employed for sentiment classification tasks [14].
Researchers have explored various features, including n-grams, syntactic patterns, and lexical
resources, to improve the performance of sentiment analysis models [16]. Additionally, feature
selection and dimensionality reduction techniques, such as Information Gain and Principal
Component Analysis, have been utilized to enhance the efficiency and accuracy of sentiment
classification [14].
3. International Journal on Cybernetics & Informatics (IJCI) Vol. 12, No.5, October 2023

Deep learning models, particularly neural networks, have demonstrated remarkable performance
in sentiment analysis tasks. Recurrent Neural Networks (RNNs) and their variants, such as Long
Short-Term Memory (LSTM) and Gated Recurrent Units (GRU), have been successful in
capturing contextual information and sequential dependencies in textual data [14]. Convolutional
Neural Networks (CNNs) have shown effectiveness in extracting local features and patterns from
text [15]. Recently, transformer-based models, such as BERT (Bidirectional Encoder
Representations from Transformers) [6], have gained prominence due to their ability to capture
contextual information and semantic nuances in large-scale language modeling tasks, including
sentiment analysis [6].
2.2. Political Forecasting and Twitter Data
The analysis of public sentiment on social media platforms, especially Twitter, has emerged as a
powerful tool for political forecasting and understanding public opinion. Twitter data, with
its vast volume and real-time nature, provides a valuable resource for capturing and analyzing
publicsentiment [10]. Various studies have explored the relationship between Twitter sentiment
and real-world events, including elections, stock markets, and social phenomena.
The predictive power of Twitter sentiment in elections has been investigated by researchers.
Tumasjan et al. [4] demonstrated that Twitter data can predict election outcomes by analyzing
political sentiment expressed in tweets. Bollen et al. [2] revealed a correlation between Twitter
mood and stock market fluctuations. Gohil and Vasanwala [3] conducted sentiment analysis on
Twitter data to analyze public opinion on Indian politics.
Furthermore, the sentiment analysis of Twitter data has been employed to uncover public
sentiment on specific political events, policies, and leaders. Researchers have utilized sentiment
analysis to study public reactions to government initiatives, election campaigns, and political
speeches [11]. The analysis of sentiment dynamics on Twitter provides insights into the shifting
public opinion and sentiment fluctuations over time [12].
In summary, sentiment analysis has advanced significantly with the adoption of machine
learning, deep learning, and transformer-based models. Twitter data has emerged as a valuable
resource forunderstanding public sentiment, predicting election outcomes, and studying political
dynamics. The combination of sentiment analysis techniques and Twitter data provides
researchers and policymakers with valuable insights into public opinion and sentiment.
3. DATA COLLECTION AND AUGMENTATION
This section outlines the data set collection process and describes the data augmentation
techniques employed for sentiment analysis. The data set was obtained through web scraping of
Twitter data, and two augmentation techniques were applied: Random Swap and Language
Transformation using Google Translate.
3.1. Data Collection and Analysis
The dataset for sentiment analysis was collected by employing web scraping techniques to
extracttweets from the Twitter platform. The Twitter API was utilized to retrieve tweets based on
specific keywords, hashtags, or user profiles, through the Tweepy library. The collected tweets
were processed to ensure the removal of personally identifiable information, thus maintaining
privacy and adhering to ethical guidelines. The full text of the tweet and the date-time stamp of
4. International Journal on Cybernetics & Informatics (IJCI) Vol. 12, No.5, October 2023
146
the tweet were collected for analysis in this study. While the majority of the tweets collected
werein English, a portion of them contained words and phrases in Kannada, as well as the Indian
national language Hindi. These tweets were not changed or translated, as the study aims
toclassify sentiment of multilingual tweets.
3.2. Random Swap
The Random Swap [18] technique involves randomly selecting two words within a sentence and
swapping their positions. By repeating this process for a given number of iterations, the sentence
structure is modified, generating new training examples. The Random Swap technique introduces
variations in sentence structure, enabling the model to learn and generalize better by considering
different word arrangements. This allowed us to augment the text to increase the robustness of
thetraining data.
3.3. Language Transformation with Google Translate
To further diversify the data set, Language Transformation using Google Translate [19] was
employed. This technique involves translating the original sentences into different
languages,such as Kannada or Hindi, using the Google Translate API. The translated versions of
the sentences were included in the augmented data set, enhancing its diversity and enabling
themodel to handle multilingual inputs effectively. Integrating the translated sentences into the
dataset enriches its linguistic diversity and enhances the models' ability to handle and
interpretmultiple languages effectively.

3.4. Data Classification
The augmented data was labeled manually into three distinct categories. Tweets labeled
"positive"had a positive sentiment towards the BJP, while those labeled "negative" had a positive
sentiment towards the opposition party, Congress. News reports, unbiased questions and
other neutraltweets were classified in the "comment" label, due to their lack of support or
opposition to anyone side. Sample tweets for each label are given in Table 1.

Although multiple people labeled the data, the reviewers were found have sufficient agreement
asper the Cohen's Kappa metric. The score, calculated using the equation 1, gave a k value of
0.813, indicating "substantial agreement". The metric was calculated using a set of common
tweets that all reviewers were made to assess.
κ =

3.5. Data Analysis
An exploration of the augmented data was performed using WordCloud, a library designed to
findthe most commonly used words and phrases in a piece of text. Three separate Wordclouds
were created, one for each data label, namely "positive", "negative", and "comment". This can be
seen in Figure 1. When analyzing the most common words for each sentiment, a few neutral
words such as "people", "election", and "vote" are seen in both Wordclouds. However,
certain termssuch as "Indian" are more commonly used by the pro-BJP tweets, while terms such
as "politics" are more common among the pro-Congress tweets. Other common rhetoric in the
pro-Congress tweets include references to the state Congress party leader Siddaramaiah,
words mocking theBJP Prime Minister Narendra Modi, and the term "Hindutva", a right wing
ideology sometimes negatively associated with the BJP. Pro-BJP tweets included many
references to Dr. S. Jaishankar,India's foreign minister, and the word "stranded", both of which
were trending during an online debate regarding Siddaramaih's response to news regarding
Indians stranded in Sudan in April. They also contained many campaign slogans for BJP, such as
"BJP4India", in support of the party's bid in the national elections in 2024
.

3.6. Sentiment over Time
The relative sentiment towards both parties in this election over time were also analyzed. A
sample of the collected tweets were grouped by day and the ratio of positive to negative
tweets for each group was calculated. This was then plotted on a line graph, displaying the
change in relative sentiment over time. The ratio of positive (pro-BJP) to negative (pro-
Congress) tweets fluctuated at about 0.95, implying a slight pro-Congress bias in the overall data
set. A few notable exceptions were found, however. The ratio increased to 1.37 on during the
time between April 18 to April 20; this corresponded to anti-Congress sentiment online
following Siddaramiah's tweet mentioned previously. Other such fluctuations occurred to a lesser
extent preceding the election, following which the ratio decreased to 0.89; this could be expected
given the landslide victory of Congress in the election.
4. METHODOLOGY
In this section, we provide a detailed account of the rigorous methodology employed in our
study, encompassing the utilization of transformer-based models, hyperparameter tuning, and
evaluation metrics, following the comprehensive analysis and pre-processing of the collected
data.

4.1. Transformers
To delve into sentiment analysis in the context of the Karnataka elections, we leveraged cutting-
edge transformer-based models, specifically designed for sentiment analysis in Indic languages.
Notably, we utilized BERT (Bidirectional Encoder Representations fromTransformers) [1] and
IndicBERT [2], which have demonstrated exceptional proficiency in capturing semantic nuances
and contextual information in textual data. Figure 2 illustrates thearchitecture of one of the top-
performing transformer-based models used in our study.
Figure 2. The architecture of BERT, a bidirectional transformer used in the study.
4.2. Models
For this study, BERT served as the primary transformer. It underwent pre-training on Next
Sentence Prediction and Masked Language Modeling, which endowed it with groundbreaking
bidirectional capabilities [6]. This unique pre-training strategy allowed BERT to predict masked
words in random inputs while simultaneously acquiring higher- order distributional statistics.
Additionally, we harnessed the power of IndicBERT as the primary multilingual transformer.
Built upon BERT's architecture and training data, IndicBERT encompassed over 11 Indic
languages, including Assamese, Bengali, Gujarati, Hindi, Kannada, Malayalam, Marathi, Oriya,
Punjabi, Tamil, and Telugu [8]. Among these, Kannada and Hindi predominated in the tweets
used for the study, although a few Telugu and Tamil tweets were also present.
RoBERTa played a significant role in fine-tuning the models. It employed dynamic masking
instead of BERT's static masking. Its training data consisted of BookCorpus, housing 11,038
books, English Wikipedia, over 124 million tweets, and tens of millions of articles on CC- News.
Furthermore, we incorporated XLNET, which was trained using BookCorpus, English
Wikipedia, Giga5, ClueWeb, and Common Crawl, resulting in a combined 158 gigabytes of
training data. Its algorithm rivaled that of BERT across numerous metrics.
DistilBERT, trained on data similar to BERT, exhibited an algorithm running 60% faster thanits
counterpart, while maintaining over 95% accuracy. Its efficiency allowed for a morerobust
and efficient training process.

DeBERTA, trained on English Wikipedia, BookCorpus, OPENWEBTEXT, content from Reddit,
and a subset of CommonCrawl (STORIES), outperformed both BERT and RoBERTAthrough the
implementation of two novel techniques – a disentangled attention mechanism and an enhanced
mask decoder. The former encoded words and computed their attention weights using two
vectors in relation to content and relative position, while the latter utilized absolute positions in
the decoding layer to assist in pre-training [23].
4.3. Hyperparameter Tuning
Hyperparameter tuning is a pivotal step in the optimization of transformer-based models for
sentiment analysis, requiring a profound understanding of their intricate interactions and effects
on model performance. In our study, we delved into a comprehensive exploration of various
hyperparameters, revealing their distinct influences on the efficacy of the models.
The learning rate, a critical hyperparameter, governs the step size during gradient descent,
impacting the speed and stability of model convergence. A judicious selection of the learning
rate within the range of [1e-5, 1e-3] was crucial. Higher learning rates accelerated convergence
but risked overshooting the optimal parameters, leading to suboptimal solutions. Conversely,
lower learning rates ensured steady progress but might slow down trainingconsiderably,
potentially hindering model optimization.
The batch size significantly affected the optimization dynamics and memory utilizationduring
training. We experimented with batch sizes ranging from 8 to 64. Larger batch sizes expedited
training by processing more samples in parallel, reducing computation time. However, they also
consumed more memory, making it challenging to train on resource- constrained devices.
Smaller batch sizes allowed more frequent parameter updates, potentially improving model
generalization, but the increased frequency could come at the cost of prolonged training times.
The number of layers and hidden units directly influenced the model's capacity to capture
complex patterns in sentiment expression. We explored layer sizes of 64, 128, and 256, along
with hidden units in the range of 64 to 512. Deeper models with a higher number of hidden units
exhibited enhanced expressive power, potentially leading to superior performance. However,
excessively deep models risked overfitting, particularly when training data was limited. On the
other hand, smaller models might lack the representational capacity to fully grasp intricate
sentiment nuances.
The number of attention heads played a crucial role in determining the models' ability to capture
interdependencies between words in the input text. We experimented with 4 to 16 attention
heads. Increasing the number of attention heads allowed for more fine-grained analysis of
semantic relationships, resulting in models that better understood contextual dependencies.
Nevertheless, an elevated number of attention heads also introduced additional computational
overhead, making it essential to strike a balance between performance gains and computational
cost.
The dropout rate was instrumental in regularizing the model during training to prevent
overfitting. Employing dropout during training inhibited neurons from becoming overlyreliant on
specific features, ensuring better generalization. We tuned the dropout rate to optimize this
regularization effect, avoiding both underfitting and excessive regularization that could hinder
the model's capacity to learn complex sentiment patterns.
The number of training epochs represented a critical factor in determining when model training
reached a suitable convergence point. We experimented with varying numbers of epochs,
9. International Journal on Cybernetics & Informatics (IJCI) Vol. 12, No.5, October 2023
151
ranging from 5 to 50. Too few epochs might lead to underfitting, where the models fail to capture
intricate patterns in the data. Conversely, too many epochs risked overfitting, causing the models
to memorize the training data, leading to poor generalization on unseen data.
By employing advanced hyperparameter tuning techniques, such as grid search and random
search, we navigated the hyperparameter space effectively. The fine-tuned transformer-based
models, combined with our diverse and representative dataset, allowed us to achieve remarkable
accuracy in capturing nuanced sentiment dynamics during the Karnataka elections. In the
subsequent section, we will present comprehensive results, with a particular focus on
IndicBERT's efficacy in sentiment analysis.
Figure 3. A comparison of training epochs to the accuracy of the models used in the study.
4.4. Evaluation Metrics
Precision, recall, and F1 score. Accuracy measured the overall correctness of sentiment
predictions, while precision and recall provided insights into the models' ability to accurately
identify positive and negative sentiments. The F1 score, a harmonic mean of precision and recall,
provided a balanced assessment of the models' performance.
To address any bias stemming from an uneven ratio of opinionated to neutral tweets in the
training data, we utilized the data augmentation techniques mentioned in Section 3. These
techniques enhanced the diversity and representativeness of the training data, leading to more
robust and unbiased models.
By employing these sophisticated evaluation metrics, we quantitatively assessed the accuracyand
effectiveness of our sentiment analysis models, providing meaningful insights into the sentiment
dynamics surrounding the Karnataka elections. The detailed results of our analysis, with a
particular focus on IndicBERT's performance, will be presented and discussed in the subsequent
sections.

5. EXPERIMENTAL RESULTS AND ANALYSIS
In this section, we present the experimental results and analyze the accuracy achieved in
predicting the sentiment towards the Bharatiya Janata Party's (BJP) defeat or the Indian National
Congress's (INC) victory in the Karnataka elections.
5.1. Results
We evaluated the performance of our sentiment analysis models on the dataset using the
evaluation metrics described earlier. Table 2 summarizes the accuracy achieved in predicting
sentiment towards the BJP's defeat or the INC's victory.
The results demonstrate the effectiveness of the transformer-based models, particularly
IndicBERT, in accurately predicting sentiment in the Karnataka election tweets. Although BERT
had a higher accuracy than IndicBERT, the better F1 score of the latter implies that it was the
best-performing model. This could be expected due to this model being specifically trained on 12
Indian languages, including Kannada and Hindi. Regardless, all models leveraged their ability to
capture contextual information and linguistic nuances, enabling them to decipher the sentiment
expressed in Indic languages with high accuracy.
Table 2. Accuracy of all sentiment classification models

BERT 0.88 0.87
RoBERTa 0.86 0.84
XLNet 0.80 0.83
FastText 0.80 0.74
DeBERTa 0.80 0.80
Baseline 0.36 0
5.2. Analysis
In-depth analysis of the sentiment analysis results revealed interesting insights into the public
sentiment towards the BJP's defeat or the INC's victory in the Karnataka elections. The sentiment
analysis models successfully captured the prevailing sentiment trends, providing valuable
information on the public perception of the political landscape. This analysis helps in
understanding the underlying factors contributing to sentiment patterns and can assist political
analysts and decision-makers in gaining insights into public sentiment dynamics.
Overall, the experimental results validate the efficacy of our methodology in sentiment analysis
for the Karnataka elections, with transformer-based models achieving high accuracy in
predictingsentiment towards the BJP's defeat or the INC's victory.

5.3. Prediction of electoral margins
The models' sentiment analysis were also applied to determine the outcome of the 2023
Karnataka elections. The fine-tuned models were given a set of 100 random tweets, and labeled
them with the categories of "positive", "negative", and "comment". The resulting ratio of positive
and negative tweets was then used to determine the predicted outcome of the election. The ratios
do not include the neutral tweets; thus, they do not add to 100. The results are given below in
Table 3. It is noteworthy that all models unanimously predicted Congress as the victor in the
elections, which was true in the actual elections. The ratio of Congress to BJP, given in the table
as well, is also of interest, as it shows how most models labeled a larger volume of tweets as
supporting Congress.
Table 3. Election Outcome Predictions
Model Ratio Prediction
IndicBERT 62:18 Congress
BERT 60:20 Congress
RoBERTa 75:15 Congress
XLNet 72:19 Congress
FastText 63:27 Congress
DeBERTa 57:22 Congress
Baseline 65:24 Congress
5.4. Implications and Relevance to Indian Politics
The findings of our study have significant implications for political decision-making in
thecontext of sentiment analysis of social media data. By employing various NLP models and
data augmentation techniques, we were able to accurately predict the sentiment towards the
defeat of the BJP or the victory of the INC in online discussions. These findings can provide
valuable insights for Indian political parties, policymakers, and campaign strategists, especially
preceding the 2024 Lok Sabha elections.
5.4.1. Improved Sentiment Analysis
The accurate prediction of sentiment towards political events can help political parties gauge
public opinion, understand voter sentiment, and tailor their campaign strategies accordingly. Our
study demonstrates that multilingual NLP models, such as IndicBERT, can effectively analyze
sentiment in social media data related to political events in countries where English may not be
the primary language of communication. By leveraging these models, political parties in such
nations can gain a deeper understanding of public sentiment and adapt their messaging and
outreach strategies to align with the prevailing sentiment.

5.4.2. Identifying Key Issues and Policy Prioritization
Analyzing sentiment data can help political parties identify key issues and prioritize
policyinitiatives based on public sentiment. As seen with the timeline of sentiment, social media
is a way for political entities to see real-time reactions to their policies and actions. By tracking
sentiment towards specific policy areas or events, parties can align their agendas with the
concerns and aspirations of the public faster than ever. Furthermore, sentiment analysis can aid
in identifying larger sentiment drivers, such as economic issues, social justice, or governance,
whichcan guide policy formulation and communication strategies in the long term.
5.4.3.Targeted Campaign Strategies
Our study also highlights the potential of data augmentation techniques in improving the
accuracyof sentiment analysis models. By incorporating techniques such as random swap and
data translation, we were able to augment the training data and enhance the performance
of themodels. This augmentation can lead to more robust sentiment analysis models, enabling
political parties to design targeted campaign strategies based on nuanced sentiment analysis.
Overall, the findings of our study provide valuable insights into sentiment analysis in the context
of political decision-making and campaigning in India. The use of NLP models and data
augmentation techniques can significantly improve sentiment prediction and aid political
parties in understanding public sentiment, shaping campaign strategies, and responding
effectively to emerging trends.
6. CONCLUSION AND FUTURE RESEARCH
In conclusion, the findings of this study hold significant implications for political decision-
making in the context of Indian politics. The successful application of sentiment analysis
using transformer-based models and data augmentation techniques offers valuable insights into
public sentiment during elections. By accurately capturing and understanding sentiment
dynamics, political actors can devise informed strategies, identify voter concerns, and tailor their
messaging to resonate with prevailing sentiments.
The utilization of transformer-based models, including BERT, IndicBERT, RoBERTa, XLNET,
DistilBERT, and DeBERTA, has proven to be instrumental in analyzing sentiment in Indic
languages, particularly in the case of the Karnataka elections. These state-of-the-art models excel
in capturing semantic nuances and contextual information, allowing for adeeper understanding
of sentiment expressions within the diverse linguistic landscape of Karnataka.
Moreover, the employment of data augmentation techniques further enhanced the
representativeness and generalizability of the dataset. The augmentation methods effectively
addressed bias concerns and ensured a balanced representation of opinionated and neutral tweets,
contributing to the models' robustness and accuracy.
As the field of AI and natural language processing continues to evolve, transformer-based
models and data augmentation techniques will likely play an increasingly vital role in political
sentiment analysis. Their adaptability to diverse languages and ability to capture complex
patterns make them indispensable tools for understanding public sentiment in multilingual and
culturally diverse societies like India.

6.1. Future Research
While our study contributes to the understanding of sentiment analysis in political contexts, there
are several avenues for future research. Firstly, exploring more advanced NLP models and
architectures could potentially yield even better results in sentiment analysis. Additionally,
investigating the application of sentiment analysis to other political events, such as key debates
orspeeches, or domains could provide a broader understanding of public sentiment and political
discourse. For example, a potential source of Congress' victory could have been the Bharat Jodo
Yatra of Congress leader Rahul Gandhi, which spanned multiple months prior to the election.
Analysis of sentiment regarding the Yatra could be collected and analyzed similar to the
WordCloud or sentiment timeline presented in this paper.
Furthermore, extending the analysis to targeted multilingual sentiment analysis, could address
the unique challenges and nuances of sentiment prediction in diverse linguistic contexts. For
example, the state of Karnataka has at least 3 well defined dialects of Kannada, in addition
to over 150 local dialects. A Kannada-specific analysis of this election's outcome could be
performed as well, using districts or dialect borders to divide the state into different regions for
targeted analysis of results and sentiment. Incorporating contextual information, such as
geographic location or demographic factors, even within the state, could also enhance the
accuracy and granularity of sentiment analysis in the future.
A limitation of our work, stemming the cultural atmosphere of India, is potential bias in the user
base of Indian twitter. The average age of Twitter users in the nation is lower than the national
average, implying that the younger generation uses the platform more. Other online platforms,
such as Facebook and Whatsapp, contain more data from the older generations, and would likely
provide better insight into the political sentiments of a larger group of Indians. Failure to
acknowledge this limitation could lead to potential issues for political entities as they may not be
able to effectively reach all of their electoral base.
In conclusion, sentiment analysis using NLP models and data augmentation techniques offers
valuable insights for political decision-making. By leveraging these techniques, political parties
and policymakers can gain a deeper understanding of public sentiment, tailor their strategies, and
effectively respond to emerging trends. Future research in this area has the potential to further
refine sentiment analysis methods and contribute to the development of robust tools for political
analysis and decision-making.
