Get Sentiment
Video
What is the get sentiment tool?
An analysis tool for sentiments brings polarity to a document and identifies the sentiments that are present.
In order to extract the negative and positive sentiments from a document you can use the get_sentiment tool with Lettria.
Importing the library & your personal API key
After you've installed the Lettria package on Python you'll need to import the library.
import lettria
Next you are going to need to include your personal API key which can be found via the Lettria platform in the dashboard.
api_key = 'your personal API key' nlp = lettria.NLP(api_key)
Adding your document
Now you will need to open your saved document. Be sure to add the name of
‘your file’ since it may differ from the name of my example file.
with open("example.txt", "r") as f: example_data = f.readlines()
Next I am going to add the document to the NLP.
nlp.add_document(example_data)
Extracting sentiments
In order to extract the sentiments from the document use the following command:
get_sentiment = nlp.get_sentiment get_sentiment(granularity = 'sentence')
Analyzing your document further
To further analyse the sentiments in your document you can also use the get_sentiment tool at the granularity of ‘subsentence’.
get_sentiment(granularity = 'subsentence')
Saving your results
In order to save your results you can use the following command.
nlp.save_results(‘example_results')
And a json file with your results that can be used for further analysis will be saved.
Code set
import lettria api_key = 'your personal API key' nlp = lettria.NLP(api_key) with open("example.txt", "r") as f: example_data = f.readlines() nlp.add_document(example_data) get_sentiment = nlp.get_sentiment get_sentiment(granularity = 'sentence') get_sentiment(granularity = 'subsentence') nlp.save_results(‘example_results')
