Use NLP to better filter tweets based on keywords

[Chintan2108]

• Currently the words are being filtered using keyword matching Code here
• This approach simply looks for the exact keywords in the tweets and filters them
• It is always possible that some tweets may contain some keywords which might have a similar meaning to algae bloom (such as eutrophication) but are not the exact same
• Such tweets while important are not filtered and instead missed out
• Use NLP and word embedding concepts to process the tweet content and find similarity with the keywords so that the tweets having words which have similar meaning to keywords but are not exact keywords are not missed out
