Stock Market Prediction Web App Using Machine Learning And Sentiment Analysis
Stock Market Prediction Web App based on Machine Learning and Sentiment Analysis of Tweets (API keys included in code). The front end of the Web App is based on Flask and Wordpress. The App forecasts stock prices of the next seven days for any given stock under NASDAQ or NSE as input by the user. Predictions are made using three algorithms: ARIMA, LSTM, Linear Regression. The Web App combines the predicted prices of the next seven days with the sentiment analysis of tweets to give recommendation whether the price is going to rise or fall

Twitter Sentiment Analysis using ConvNet
A tool to
- predict sentiment "positiveness" for tweets
How to use it?
>> from sentiment import sentiment_score
>> print sentiment_score(u"I love you")
0.9999
It returns a sentiment index ranging from 0 (negative sentiment) to 1 (positive sentiment).
Online Demo
- predict sentiment "positiveness" for single tweets
- gain an overview of the "positiveness" of hashtags
