Project leveraging various tools to analyze and score sentiments in tweets and documents
- Tools:Tweepy | Natural Language Toolkit (NLTK) | iPython | Bing API | Google Custom Search API | SentiWordNet | AFINN-111
- The project, dubbed 'Sentiment Analysis', involves downloading tweets using the 'ExtractTweet.py' script, which can be configured using the config.json file, including setting up consumer keys and access tokens obtained from Twitter Developer account
- After downloading, three scripts ('DeriveTweetSentimentEasy.py', 'NewTermSentimentInference.py', 'SentiWordnet.py') can be used to assign sentiment scores to tweets. These scripts leverage different approaches and vocabularies to analyze sentiment, such as the AFINN-111.txt vocabulary and SentiWordNet
- The project also includes 'DocumentSentimentClassification.py' for document sentiment classification, with configurable parameters like file name and API keys for Bing and Google. It offers an interactive example with iPython for a more hands-on experience
