Extracting directed emotions at scale with LMs

Perspectives: Directed Emotion Extraction

Overview

The Perspectives library offers an easy way to extract directed emotions at scale with its cutting-edge emotion extraction model. It is built on top of the powerful pandas DataFrame functionality, with added support for semantic search. The library introduces several novel methods for text analytics, perfect for dealing with customer feedback, analyzing semantic trends, or profiling entities within a text.

Main Features

1. Easily extract perspectives from text: The get_perspectives() function allows you to extract the speaker's identity, emotions, and the object of these emotions, giving you useful insights about the emotions in your text.

2. Powerful search capabilities: You can search the dataset based on the speaker, emotion, object, and reason. The search method leverages the sentence transformer models for semantic search functionality, providing you with outputs that are spot-on.

3. Improved machine learning models: The library efficiently interfaces with PyTorch BART model for Seq2Seq learning and the mpnet-base model for sentence-transformations, which provides powerful text representation for ML models.

4. Structured emotional outcomes: All outputs are neatly structured in DataFrame format, allowing for easy downstream analysis and visualizations.

Installation

pip install perspectives

Usage

from perspectives import DataFrame

# Load DataFrame
df = DataFrame(texts = [list of sentences]) 

# Load model
df.load_model() 

# Get perspectives
df.get_perspectives()

# Search
df.search(speaker='...', emotion='...')

# Profile
df.profile_graph(speaker='...')
