Asent

Fast, flexible and transparent sentiment analysis

Asent is a rule-based sentiment analysis library for Python made using spaCy. It is inspired by VADER, but uses a more modular ruleset, that allows the user to change e.g. the method for finding negations. Furthermore it includes visualisers to visualize the model predictions, making the model easily interpretable.

Example

import spacy import asent # load spacy pipeline nlp = spacy.blank('en') nlp.add_pipe('sentencizer') # add the rule-based sentiment model nlp.add_pipe('asent_en_v1') # try an example text = 'I am not very happy, but I am also not especially sad' doc = nlp(text) # print polarity of document, scaled to be between -1, and 1 print(doc._.polarity) # neg=0.0 neu=0.631 pos=0.369 compound=0.7526 # Naturally, a simple score can be quite unsatisfying, thus Asent implements a series of visualizer to interpret the results: asent.visualize(doc, style='prediction') # or asent.visualize(doc[:5], style='analysis')
