NBA Sentiment Analysis and Prediction

Overview

This project displays visualizations of historical data, predictions, and sentiment analysis data for five NBA teams: Lakers, Celtics, Warriors, Rockets, and Bulls. The historical data has been collected using the NEWS API (articles) and the balldontlie API (past NBA scores). AWS has been used for making predictions (SageMaker) and performing sentiment analysis (Comprehend). The score predictions were made using the historical scores, while the sentiment analysis was made based on the tone of the articles about each team.

Features

• Visualization of historical data.
• Sentiment analysis for each team's related news articles.
• Real-time prediction of each team's future scores.

Data Collection

Score data of the five NBA teams was collected using the Balldontlie API (score) and the News API (articles).

Sentiment Analysis

Amazon Comprehend was used to perform sentiment analysis on the news articles related to each team. The results are displayed on a pie chart, with each slice representing the ratio of positive, negative, and neutral news articles.

Prediction Model

Amazon SageMaker was used to train a logistic regression model on historical data for each team. The model predicts the scores of each team in upcoming matches. The results are displayed on a line chart.
