This project focuses on analyzing customer sentiment through the implementation of the NLTK (Natural Language Toolkit) algorithm on product web reviews. The process involves extracting data from a SQL database, applying sentiment analysis using Python, generating CSV files, and then visualizing the data in Power BI for deeper insights.
- Python 3.x
- NLTK (Natural Language Toolkit)
- SQL Server (or any SQL database)
- Power BI Desktop (for visualization)
-
Database Setup:
- Ensure the availability of the SQL database containing the product web reviews.
- Make sure the necessary credentials and permissions are set up for access.
-
Python Script for SQL Extraction (extract_data.py):
- Utilize this script to connect to the SQL database and extract relevant data.
- Ensure that the script handles any necessary data transformations or filtering required.
-
Python Script for NLTK Algorithm (sentiment_analysis.py):
- This script implements the NLTK algorithm for sentiment analysis.
- It takes the extracted data as input and generates sentiment scores for each review.
-
Python Script for Generating CSV File (generate_csv.py):
- After sentiment analysis, use this script to generate CSV files containing the processed data.
- Customize the script to include any additional metadata or formatting required.
-
Automatic Upload of CSV File in Power BI:
- Set up an automated process or schedule to upload the generated CSV files to Power BI.
- Utilize Power BI APIs or any relevant integration tools for seamless data transfer.
-
Data Processing in Power BI:
- Upon uploading the CSV files, perform necessary data processing steps in Power BI.
- This may include data cleansing, transformation, and merging with other datasets if needed.
-
Visualization in Power BI:
- Leverage Power BI's visualization capabilities to create insightful dashboards and reports.
- Design visualizations that effectively communicate customer sentiment trends and patterns.
