From zero to hero

Texthero is a python toolkit that help you work with text-based dataset quickly and effortlessly. Texthero is very simple to learn and designed to be used on top of Pandas.

You can think of Texthero as a tool to help you understand and work with text-based dataset. Given a tabular dataset, it's easy to grasp the main concept. Instead, given a text dataset it's harder to have quick insights of the underline data. With Texthero, preprocessing (cleaning), mapping words into vectors and visualize the reduced vector space takes only a couple lines of code.

To use Texthero, you don't have to spend hours understanding complex and messy code. Texthero is composed of only three python modules preprocessing.py, representation.py, visualization.py and it's well documented. Other than that, Texthero is optimized to be very fast.

Installation

Texthero is available on the Python Package Index and can be installed via pip.

pip install texthero

☝️Under the hoods, Texthero makes use of multiple NLP and machine learning toolkits such as Gensim, NLTK, SpaCy and scikit-learn. You don't need to install them all separately, pip will take care of that for you.

Getting started

The best way to learn Texthero is probably via the Getting Started official documentation. In case you are a pro python user, then help(texthero) should suffices.

Example

import texthero.texthero as hero
import pandas as pd

df = pd.DataFrame(["hello world", "hello", "world"], columns='text')
df = hero.do_preprocess(df)
df = hero.do_tfidf(df)
df = hero.do_pca(df)
hero.scatterplot(df)

(The same example can also be found as a "getting-started guide" here: ...)

API

Texthero is composed of three modules: preprocessing.py, representation.py and [visualization.py])(/texthero/visualization.py).

⚒️ 1. Preprocessing

Scope: prepare the text data for further analysis.

Complete documentation: preprocessing

📒 2. Representation

Job: map text data into vectors and do dimensionality reduction.

Supported representation algorithms:

  1. Term frequency, inverse document frequency (do_tfidf)
  2. Word2Vec from Gensim [🔜]
  3. GloVe [🔜]
  4. Transformers [🔜]

Supported dimensionality reduction algorithms:

  1. Principal component analysis (do_pca)
  2. Non-negative matrix factorization (do_nmf)

Complete documentation: representation

🔮 3. Visualization

Job: collection of functions to both summarize the main facts regarding the data and visualize the results. This part is very opinionated and ideal for anyone that needs a quick solution to visualize on screen the text data for instance during a text exploratory data analysis (EDA).

Most common functions:

  • Text scatterplot. Handy when coupled with dimensionality reduction algorithms such as pca.
  • Most common words
  • Most common words between two entities [🔜]

Complete documentation: visualization
