NLP Primitives

nlp_primitives is a Python library with Natural Language Processing Primitives, intended for use with Featuretools.

nlp_primitives allows you to make use of text data in your machine learning pipeline in the same pipeline as the rest of your data.

Install

pip install 'featuretools[nlp_primitives]'

Calculating Features

With nlp_primitives primtives in featuretools, this is how to calculate the same feature.

from featuretools.nlp_primitives import PolarityScore

data = ["hello, this is a new featuretools library",
        "this will add new natural language primitives",
        "we hope you like it!"]

pol = PolarityScore()
pol(data)

0    0.365
1    0.385
2    1.000
dtype: float64

Combining Primitives

In featuretools, this is how to combine nlp_primitives primitives with built-in or other installed primitives.

import featuretools as ft
from featuretools.nlp_primitives import TitleWordCount
from featuretools.primitives import Mean

entityset = ft.demo.load_retail()
feature_matrix, features = ft.dfs(entityset=entityset, target_entity='products', agg_primitives=[Mean], trans_primitives=[TitleWordCount])

feature_matrix.head(5)

           MEAN(order_products.quantity)  MEAN(order_products.unit_price)  MEAN(order_products.total)  TITLE_WORD_COUNT(description)
