LingFeat is an innovative Python package designed for extracting a plethora of linguistic features that help assess text readability and complexity. Whether you’re a researcher or a casual user interested in understanding the intricacies of language, this guide will navigate you through utilizing LingFeat effectively.

Overview

At its core, LingFeat extracts 255 linguistic features from English text. These features are classified into five primary categories:

• Advanced Semantic (AdSem): Measures the complexity of meaning structures.
• Discourse (Disco): Assesses coherence and cohesion in text.
• Syntactic (Synta): Examines grammatical structure complexity.
• Lexico Semantic (LxSem): Analyzes specific word or phrase difficulty.
• Shallow Traditional (ShTra): Calculates traditional text difficulty metrics.

Setting Up LingFeat

Follow these steps to install LingFeat and start extracting linguistic features:

Installation

• Option 1: Use pip to install LingFeat:

  pip install lingfeat

• Option 2: Clone the repository and install dependencies manually (recommended):

  git clone https://github.com/brucewlee/lingfeat.git
  pip install -r lingfeat/requirements.txt

Using LingFeat

Now, let’s dive into how you can use LingFeat effectively, depending on your expertise level.

A. General Usage (Basic)

If you’re not deeply into linguistics, you can focus on the fundamental features. Here’s a simple Python code snippet that returns a dictionary of readability scores:

from lingfeat import extractor
text = "Your text goes here."
LingFeat = extractor.pass_text(text)
LingFeat.preprocess()
TraF = LingFeat.TraF_()
print(TraF)

B. Advanced Language Analysis (ResearchMLNLP Purpose)

For advanced users, you can leverage various subgroups of features by importing the essentials and calling specific methods:

Import this is the only import you need
from lingfeat import extractor
text = "Your advanced text goes here."
LingFeat = extractor.pass_text(text)
LingFeat.preprocess()

# Extract various feature groups
WoKF = LingFeat.WoKF_()  # Wikipedia Knowledge Features
EnDF = LingFeat.EnDF_()  # Entity Density Features
PhrF = LingFeat.PhrF_()  # Noun Verb Adjective Phrase Features

Understanding LingFeat’s Methods: An Analogy

Think of LingFeat as a culinary chef preparing a complex dish, wherein each ingredient represents a different linguistic feature. Just as a chef measures and combines various ingredients to enhance the flavor and texture of a dish, LingFeat combines various linguistic features to present a comprehensive analysis of text.

Troubleshooting Tips

If you encounter any issues, consider the following:

• Ensure you have installed the necessary dependencies, especially spaCy by running:

  python -m spacy download en_core_web_sm

• If your installation fails, check your Python version compatibility (Python 3.5+ is required).
