""" #App: NLP App with Streamlit Credits: Streamlit Team, Marc Skov Madsen(For Awesome-streamlit gallery) Description This is a Natural Language Processing(NLP) base Application that is useful for basic NLP tasks such as follows; + Tokenization(POS tagging) & Lemmatization(root mean) using Spacy + Named Entity Recognition(NER)/Trigger word detection using SpaCy + Sentiment Analysis using TextBlob + Document/Text Summarization using Gensim/T5 both for Bangla Extractive and English Abstructive. This is built with Streamlit Framework, an awesome framework for building ML and NLP tools.
