Algorithmically predict public sentiment on a topic using VADER sentiment analysis

abraham

Algorithmically predict public sentiment on a topic using flair sentiment analysis.

Installation

Installation is simple; just install via pip.

$ pip3 install abraham3k

Basic Usage

The most simple way of use is to use the _summary functions.

from abraham3k.prophets import Abraham

watched = ["amd", "tesla"]

darthvader = Abraham(
      news_source="newsapi",
      newsapi_key="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      bearer_token="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      weights={"desc": 0.33, "text": 0.33, "title": 0.34},
)

scores = darthvader.news_summary(
      watched,
      start_time="2021-4-20T00:00:00Z" 
      end_time="2021-4-22T00:00:00Z",
)
print(scores)

'''
{'amd': (56.2, 43.8), 'tesla': (40.4, 59.6)} # returns a tuple (positive count : negative count)
'''


scores = darthvader.twitter_summary(
      watched,
      start_time="2021-4-20T00:00:00Z" 
      end_time="2021-4-22T00:00:00Z",
)
print(scores)

'''
{'amd': (57, 43), 'tesla': (42, 58)} # returns a tuple (positive count : negative count)
'''

You can run the function news_sentiment to get the raw scores for the news. This will return a nested dictionary with keys for each topic.

from abraham3k.prophets import Abraham

darthvader = Abraham(news_source="google") 

scores = darthvader.news_sentiment(["amd", 
                               "microsoft", 
                               "tesla", 
                               "theranos"],
                               )
print(scores['tesla']['text'])

'''

The same way works for the twitter API (see below for integrating twitter usage).

from abraham3k.prophets import Abraham

darthvader = Abraham(news_source="google") 

scores = darthvader.twitter_sentiment(["amd", 
                                    "microsoft", 
                                    "tesla", 
                                    "theranos"]
                                    )

You can also just use a one-off function to get the sentiment from both the news and twitter combined.

from abraham3k.prophets import Abraham

darthvader = Abraham(news_source="google") 

scores = darthvader.summary(["tesla", "amd"], weights={"news": 0.5, "twitter": 0.5})

print(scores)
'''
{'amd': (59.0, 41.0), 'tesla': (46.1, 53.9)}
'''

There's also a built-in function for building a dataset of past sentiments. This follows the same format as the non-interval functions (twitter_summary_interval, news_summary_interval, summary_interval).

from abraham3k.prophets import Abraham

# this works best using the offical twitter api rather than twint
darthvader = Abraham(bearer_token="xxxxxxxxxxxxxxxxxxxxxx") 

scores = twitter_summary_interval(
        self,
        ["tesla", "amd"],
        oldest=datetime.now() - timedelta(days=1),
        newest=datetime.now(),
        interval=timedelta(hours=12),
        offset=timedelta(hours=1),
        size=100,
    )

Changing News Sources

Abraham supports two news sources: Google News and NewsAPI. Default is Google News, but you can change it to NewsAPI by passing Abraham(news_source='newsapi', api_key='<your api key') when instantiating. I'd highly recommend using NewsAPI. It's much better than the Google News API. Setup is really simple, just head to the register page and sign up to get your API key.

Twitter Functionality

I'd highly recommend integrating twitter. It's really simple; just head to Twitter Developer to sign up and get your bearer token. If you don't want to sign up, you can actually use it free with the twint API (no keys needed). This is the default.

Updates

I've made it pretty simple (at least for me) to push updates. Once I'm in the directory, I can run $ ./build-push 1.2.0 "update install requirements" where 1.2.0 is the version and "update install requirements" is the git commit message. It will update to PyPi and to the github repository.

Notes

Currently, there's another algorithm in progress (SALT), including salt.py and salt.ipynb in the abraham3k/ directory and the entire models/ directory. They're not ready for use yet, so don't worry about importing them or anything.

Detailed Usage

Coming soon. However, there is heavy documentation in the actual code.
