Popular Python package Spacy is used for natural language processing. Removing named entities from a text, such as people's names, is one of the things you can perform with Spacy. This can be done using the ents property of a Spacy document, which returns a list of named entities that have been identified in the text.  


Removing names using Spacy can have several applications, including:  

  • Anonymizing text data: Removing names from text data can be useful for protecting the privacy of individuals mentioned in the data.  
  • Text summarization: Removing named entities, such as names of people, organizations, and locations, can help to reduce the amount of irrelevant information in a text and improve the overall readability of the summary.  
  • Text classification: Removing named entities can help to improve the performance of text classification models by reducing the amount of noise in the text and making it easier for the model to identify the relevant features.  
  • Sentiment Analysis: Removing names can help to improve the accuracy of sentiment analysis by reducing the amount of personal bias and opinion present in the text.  


Here is how you can remove names using Spacy:

Code

In this solution we used spacy library of python.

using Spacy to remove names from a data frame in Python 3.9

Dependent Libraries : 
import spacy
import pandas as pd

# Test dataframe
df = pd.DataFrame({'ID':['A123','X907'], 'Comment':['I am five years old, and my name is John', 'Today I met with Dr. Jacob']})

# Initialize the model
nlp = spacy.load('en_core_web_trf')

def remove_names(text):
    doc = nlp(text)
    newString = text
    for e in reversed(doc.ents):
        if e.label_ == "PERSON": # Only if the entity is a PERSON
            newString = newString[:e.start_char] + newString[e.start_char + len(e.text):]
    return newString

df['Comment'] = df['Comment'].apply(remove_names)
print(df.to_string())

     ID                               Comment
0  A123  I am five years old, and my name is
1  X907                 Today I met with Dr.
  1. Copy the code using the "Copy" button above, and paste it in a Python file in your IDE.
  2. Enter the Text
  3. Run the file to annihilate Names in the text


I hope you found this useful. I have added the link to dependent libraries, version information in the following sections.


I found this code snippet by searching for "Using Spacy to remove names from a data frame "in kandi. You can try any such use case.


Note


In this snippet we are using a Language Model (en_core_wb_trf)

  1. Download the model using the command python-m spacy download en_core_web_trf.
  2. Paste it in your terminal and download it

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.


  1. The solution is created in Python 3.7.15 Version
  2. The solution is tested on Spacy 3.4.3 Version
  3. the solution is tested on Pandas 1.3.5 Version


Using this solution, we can remove Names in text with the help of function in spacy . This process also facilities an easy to use, hassle free method to create a hands-on working version of code which would help us remove names in the text in python.
