How to run the app

Clone the repository

git clone https://github.com/adimyth/iplbot.git

Install the requirements

pip install -r requirements.txt

Run the app

streamlit run app.py

How it works

1. Run extractor.py to extract text from the following list of wikipedia pages

   • Indian Premier League
   • Category:Indian Premier League coaches
   • Mumbai Indians
   • Chennai Super Kings
   • Kolkata Knight Riders
   • Rajasthan Royals
   • Sunrisers Hyderabad
   • Kings XI Punjab
   • Delhi Capitals This will create a file called ipl.txt which will contain the text from all the above links

2. Given an input sentence, generate_response function in bot.py does the following

   • Lowercase the entire string
   • Removing punctuation marks
   • Word tokenization
   • Lemmatization
   • Train a tfidf vectorizer on the sentences generated in step 1 as well as on the input sentence
   • Uses cosine similarity to find the two closest vectors
   • Sorts the vector similarity in decreasing order & chooses the first vector
   • Gets the corresponding sentence & capitalizes it
