In 2024, political strategies are no longer crafted solely by human instinct and experience; artificial intelligence (AI)plays an integral role in shaping decisions, especially in data-rich environments like politics. The ability to sift through vast amounts of data—news articles, social media, public statements—and derive actionable insights gives political campaigns a significant edge. In this article, we delve into how AI, driven by sophisticated sentiment analysis, opinion mining, and predictive modeling, is reshaping Malaysian political strategies.
Our analysis focuses on a hypothetical case where data from various public domains such as news websites and social media are aggregated to gauge public opinion on major political figures in Malaysia. We will illustrate how to collect, clean, analyze, and verify this data using both R and Python, guiding you through every step, from building web crawlers to performing Exploratory Data Analysis (EDA).
Step 1: Data Aggregation with Web Crawlers
The first step in our analysis involves gathering data. We focus on public sources like news websites, blogs, and social media. For this, we need web crawlers to automatically extract data from web pages.
Python Code for Web Crawling (BeautifulSoup & Requests):
python
import requests
from bs4 import BeautifulSoup
# Example URL from a public news site
url = 'https://example-news-site.com/malaysia-politics'
response = requests.get(url)
# Parsing the HTML content using BeautifulSoup
soup = BeautifulSoup(response.content, 'html.parser')
# Extracting article titles and content
articles = soup.find_all('article')
data = []
for article in articles:
title = article.find('h2').text.strip()
content = article.find('div', class_='content').text.strip()
data.append({'title': title, 'content': content})
# Saving the data as HTML file for future referencewithopen('news_data.html', 'w', encoding='utf-8') as file:
file.write(soup.prettify())
R Code for Web Crawling (rvest & httr):
r
library(rvest)
library(httr)# URL of the news site
url <-'https://example-news-site.com/malaysia-politics'# Get the HTML content
webpage <- read_html(url)# Extracting article titles and content
titles <- webpage %>% html_nodes('h2')%>% html_text(trim =TRUE)
content <- webpage %>% html_nodes('.content')%>% html_text(trim =TRUE)# Creating a dataframe
news_data <- data.frame(title = titles, content = content)# Saving the HTML file for reference
write_html(webpage,"news_data.html")
Here, we’ve employed BeautifulSoup and rvest to scrape data from public news websites, focusing on political articles. This data will serve as the foundation for further analysis.
Step 2: Data Verification and Cleaning
Once the data has been scraped, the next step is to verify its integrity. We need to ensure that the extracted data is clean, accurate, and relevant.
Python Code for Data Cleaning and Verification:
python
import pandas as pd
# Load data into a pandas DataFrame
df = pd.DataFrame(data)
# Drop any rows with missing titles or content
df_clean = df.dropna(subset=['title', 'content'])
# Verify data integrityprint(df_clean.info())
print(df_clean.head())
# Check for duplicates
df_clean = df_clean.drop_duplicates(subset='content')
# Verifying if any irrelevant or repeated data is present
df_clean = df_clean[~df_clean['content'].str.contains('Advertisement|Sponsored')]
R Code for Data Cleaning and Verification:
r
library(dplyr)# Load the data into a dataframe
df <- as.data.frame(news_data)# Remove rows with missing content or titles
df_clean <- df %>% filter(!is.na(title),!is.na(content))# Check for duplicates and drop them
df_clean <- df_clean %>% distinct(content, .keep_all =TRUE)# Removing irrelevant content like advertisements
df_clean <- df_clean %>% filter(!grepl('Advertisement|Sponsored', content))
At this stage, we ensure that only relevant and clean data proceeds to the next steps. The removal of irrelevant information, such as advertisements, is crucial in producing accurate analysis.
Step 3: Exploratory Data Analysis (EDA)
EDA helps us understand the underlying patterns in the data. For political analysis, we might want to see how frequently certain political figures are mentioned, the tone of these mentions, or even the topics of most interest.
Python Code for EDA:
python
import matplotlib.pyplot as plt
from wordcloud import WordCloud
# Generate a word cloud for the content
text = ' '.join(df_clean['content'].tolist())
wordcloud = WordCloud(width=800, height=400, background_color='white').generate(text)
# Display the word cloud
plt.figure(figsize=(10, 5))
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis('off')
plt.show()
# Checking the top 10 most frequent wordsfrom collections import Counter
words = text.split()
word_counts = Counter(words)
print(word_counts.most_common(10))
R Code for EDA:
r
library(wordcloud)
library(tm)# Generate a word cloud
corpus <- Corpus(VectorSource(df_clean$content))
corpus <- tm_map(corpus, content_transformer(tolower))
corpus <- tm_map(corpus, removePunctuation)
corpus <- tm_map(corpus, removeWords, stopwords("en"))# Plot the word cloud
wordcloud(corpus, max.words=100, random.order=FALSE, colors=brewer.pal(8,"Dark2"))# Get top 10 most frequent words
dtm <- DocumentTermMatrix(corpus)
freq <- colSums(as.matrix(dtm))
top_words <- sort(freq, decreasing=TRUE)[1:10]
print(top_words)
The word cloud visualizations and frequent word counts give us insight into which topics or political figures dominate the discourse. These initial observations set the stage for deeper sentiment analysis.
Step 4: Data Enrichment and Sentiment Analysis
Sentiment analysis allows us to determine the emotional tone of the articles. This helps in understanding public opinion about political figures and topics.
Python Code for Sentiment Analysis (TextBlob):
python
from textblob import TextBlob
# Function to classify sentimentdefget_sentiment(text):
analysis = TextBlob(text)
if analysis.sentiment.polarity > 0:
return'positive'elif analysis.sentiment.polarity == 0:
return'neutral'else:
return'negative'# Apply sentiment analysis
df_clean['sentiment'] = df_clean['content'].apply(get_sentiment)
# View the distribution of sentimentsprint(df_clean['sentiment'].value_counts())
R Code for Sentiment Analysis (SentimentAnalysis):
r
library(SentimentAnalysis)# Perform sentiment analysis
sentiment_scores <- analyzeSentiment(df_clean$content)# Convert scores to positive, negative, or neutral
df_clean$sentiment <- convertToDirection(sentiment_scores$SentimentQDAP)# View the distribution of sentiments
table(df_clean$sentiment)
By applying sentiment analysis, we can now identify how each political figure or issue is perceived by the public. The data is enriched with sentiment labels, giving us a clearer picture of public sentiment trends.
Step 5: Predictive Modeling for Political Sentiment Trends
With the cleaned and enriched data, we can now apply predictive modeling to anticipate future trends in political sentiment.
Python Code for Predictive Modeling (Linear Regression):
python
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
# Preparing data
df_clean['length'] = df_clean['content'].apply(len)
X = df_clean[['length']] # Using content length as a simple feature
y = df_clean['sentiment'].apply(lambda x: 1if x == 'positive'else0) # Binary target# Train-test split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)
# Train a simple linear regression model
model = LinearRegression()
model.fit(X_train, y_train)
# Evaluate the modelprint(f"Model Accuracy: {model.score(X_test, y_test)}")
R Code for Predictive Modeling (Logistic Regression):
r
library(caret)# Preparing data
df_clean$length<- nchar(df_clean$content)
df_clean$sentiment_binary <- ifelse(df_clean$sentiment =='positive',1,0)# Train-test split
set.seed(123)
trainIndex <- createDataPartition(df_clean$sentiment_binary, p =.8,list=FALSE)
trainData <- df_clean[trainIndex,]
testData <- df_clean[-trainIndex,]# Logistic regression model
model <- glm(sentiment_binary ~length, data = trainData, family = binomial)# Model summary
summary(model)# Prediction accuracy
pred <- predict(model, testData, type ='response')
testData$pred_binary <- ifelse(pred >0.5,1,0)
accuracy <- mean(testData$pred_binary == testData$sentiment_binary)
print

AI-Driven Decision Making in Malaysian Politics: How Artificial Intelligence is Reshaping Political Strategies in 2024
Introduction
In 2024, political strategies are increasingly powered by artificial intelligence (AI). This transformation is especially visible in data-rich environments like politics, where decisions are no longer driven solely by intuition but by deep data insights. In Malaysian politics, AI is quietly playing a pivotal role in shaping campaigns, from analyzing public sentiment to predicting voter behavior.
This article explores how AI, fueled by sentiment analysis, opinion mining, and predictive modeling, is revolutionizing political strategy in Malaysia. Using publicly available data, we demonstrate the step-by-step process of collecting, cleaning, and analyzing data to gain valuable insights into public opinion. The article also incorporates both R and Python programming languages to show how to aggregate, verify, and enrich data, alongside conducting Exploratory Data Analysis (EDA).
Step 1: Data Aggregation with Web Crawlers
The first step in our analysis involves gathering data from public sources such as news websites and blogs. To automate this process, we utilize web crawlers that collect relevant data on political figures and topics.
Python Code for Web Crawling (BeautifulSoup & Requests):
python
import requests
from bs4 import BeautifulSoup
# Example URL from a public news site
url = 'https://example-news-site.com/malaysia-politics'
response = requests.get(url)
# Parsing the HTML content using BeautifulSoup
soup = BeautifulSoup(response.content, 'html.parser')
# Extracting article titles and content
articles = soup.find_all('article')
data = []
for article in articles:
title = article.find('h2').text.strip()
content = article.find('div', class_='content').text.strip()
data.append({'title': title, 'content': content})
# Saving the data as HTML file for future referencewithopen('news_data.html', 'w', encoding='utf-8') as file:
file.write(soup.prettify())
R Code for Web Crawling (rvest & httr):
r
library(rvest)
library(httr)# URL of the news site
url <-'https://example-news-site.com/malaysia-politics'# Get the HTML content
webpage <- read_html(url)# Extracting article titles and content
titles <- webpage %>% html_nodes('h2')%>% html_text(trim =TRUE)
content <- webpage %>% html_nodes('.content')%>% html_text(trim =TRUE)# Creating a dataframe
news_data <- data.frame(title = titles, content = content)# Saving the HTML file for reference
write_html(webpage,"news_data.html")
Using web crawlers, we successfully gather content from public news sources. This provides us with a wealth of textual data related to Malaysian political figures.
Step 2: Data Verification and Cleaning
Once we have the data, it’s crucial to clean and verify its integrity before proceeding with analysis. In this stage, we remove any irrelevant content, duplicates, and advertisements.
Python Code for Data Cleaning:
python
import pandas as pd
# Load data into a pandas DataFrame
df = pd.DataFrame(data)
# Drop any rows with missing titles or content
df_clean = df.dropna(subset=['title', 'content'])
# Verify data integrityprint(df_clean.info())
print(df_clean.head())
# Check for duplicates
df_clean = df_clean.drop_duplicates(subset='content')
# Verifying if any irrelevant or repeated data is present
df_clean = df_clean[~df_clean['content'].str.contains('Advertisement|Sponsored')]
R Code for Data Cleaning:
r
library(dplyr)# Load the data into a dataframe
df <- as.data.frame(news_data)# Remove rows with missing content or titles
df_clean <- df %>% filter(!is.na(title),!is.na(content))# Check for duplicates and drop them
df_clean <- df_clean %>% distinct(content, .keep_all =TRUE)# Removing irrelevant content like advertisements
df_clean <- df_clean %>% filter(!grepl('Advertisement|Sponsored', content))
At this stage, the dataset is cleaned of irrelevant material, ensuring that only quality data proceeds to the next step. The data is now ready for exploratory analysis.
Step 3: Exploratory Data Analysis (EDA)
Exploratory Data Analysis (EDA) allows us to discover patterns, trends, and relationships within the data. In this case, we examine the most frequently mentioned words in political discussions to identify prominent topics.
Python Code for Word Cloud:
python
from wordcloud import WordCloud
import matplotlib.pyplot as plt
# Generate a word cloud for the content
text = ' '.join(df_clean['content'].tolist())
wordcloud = WordCloud(width=800, height=400, background_color='white').generate(text)
# Display the word cloud
plt.figure(figsize=(10, 5))
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis('off')
plt.show()
R Code for Word Cloud:
r
library(wordcloud)
library(tm)# Generate a word cloud
corpus <- Corpus(VectorSource(df_clean$content))
corpus <- tm_map(corpus, content_transformer(tolower))
corpus <- tm_map(corpus, removePunctuation)
corpus <- tm_map(corpus, removeWords, stopwords("en"))# Plot the word cloud
wordcloud(corpus, max.words=100, random.order=FALSE, colors=brewer.pal(8,"Dark2"))
Word Cloud Visualization:
![Word Cloud](<<previously generated image>>) Figure 1: Word cloud showcasing the most common words in political discussions.
Next, we analyze the top 10 most frequent words from the dataset to see which political topics dominate public discourse.
Python Code for Top 10 Most Frequent Words:
python
from collections import Counter
import seaborn as sns
# Simulate text data and count word frequencies
words = text.split()
word_counts = Counter(words)
# Get the 10 most common words
common_words = word_counts.most_common(10)
words, counts = zip(*common_words)
# Create a bar plot for the top 10 words
plt.figure(figsize=(10, 6))
sns.barplot(x=list(counts), y=list(words), palette="Blues_d")
plt.title("Top 10 Most Frequent Words")
plt.xlabel("Frequency")
plt.ylabel("Words")
plt.show()
R Code for Top 10 Most Frequent Words:
r
library(ggplot2)# Create a document term matrix
corpus_dtm <- DocumentTermMatrix(corpus)
freq <- sort(colSums(as.matrix(corpus_dtm)), decreasing =TRUE)
top_words <- head(freq,10)# Create a bar plot for the top 10 words
barplot(top_words, las =2, col ="lightblue", main ="Top 10 Most Frequent Words")
Top 10 Most Frequent Words:
![Top 10 Words](<<previously generated image>>) Figure 2: Bar plot of the top 10 most frequent words in the dataset.
Step 4: Sentiment Analysis – Understanding Public Perception
Once we have identified the major themes, we move on to sentiment analysis. This helps us assess how political figures are perceived—whether positively, negatively, or neutrally.
Python Code for Sentiment Analysis (TextBlob):
python
from textblob import TextBlob
# Function to classify sentimentdefget_sentiment(text):
analysis = TextBlob(text)
if analysis.sentiment.polarity > 0:
return'positive'elif analysis.sentiment.polarity == 0:
return'neutral'else:
return'negative'# Apply sentiment analysis
df_clean['sentiment'] = df_clean['content'].apply(get_sentiment)
# View the distribution of sentimentsprint(df_clean['sentiment'].value_counts())
R Code for Sentiment Analysis (SentimentAnalysis):
r
library(SentimentAnalysis)# Perform sentiment analysis
sentiment_scores <- analyzeSentiment(df_clean$content)# Convert scores to positive, negative, or neutral
df_clean$sentiment <- convertToDirection(sentiment_scores$SentimentQDAP)# View the distribution of sentiments
table(df_clean$sentiment)
Sentiment Distribution Pie Chart:
![Sentiment Distribution](<<previously generated image>>) Figure 3: Pie chart illustrating the distribution of positive, neutral, and negative sentiments in the dataset.
Step 5: Predictive Modeling for Political Sentiment Trends
Finally, we apply predictive modeling to understand future sentiment trends. By training a simple regression model, we can predict whether future content is likely to be positive, neutral, or negative based on content features such as text length.
Python Code for Predictive Modeling (Linear Regression):
python
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LinearRegression
# Preparing data
df_clean['length'] = df_clean['content'].apply(len)
X = df_clean[['length']] # Using content length as a simple feature
y = df_clean['sentiment'].apply(lambda x: 1if x == 'positive'else0) # Binary target# Train-test split
X_train, X
