If you haven’t noticed we have rebranded and started using DALL·E to improve our websites user experience. We really have fallen in love with the output. However we are always removing the bottom 16 pixels because this is where DALL·E puts their companies logo.
Another important aspect of this script is the ability to decrease the image quality, enabling it to load faster on more devices, thereby decreasing the load time on our website. Imagine of the header image of this blog post took 1 minute to load on your cellphone and imagine trying to wait 1 minute for a website to load. When adding large images to the internet, often there’s a need to lower the quality. This script automatically manages the quality of your image, and you can change the settings by updating the quality variable.
To remove the labeling created by DALL·E’s workflow, we can apply a quick python solution to solve the problem.
We hope this allows you a quicker path to using DALL·E designs in your future.
To begin, you’ll need a directory of images and your computer turned on.
import os
from PIL import Image
# Set the directory containing the image files
directory = "C:/Users/ityle/Downloads/Edit"
# Set the output quality (0-100)
quality = 75
# Set the pixel trim size
trim = 16
# Get a list of the files in the directory
files = os.listdir(directory)
# Iterate through the files
for file in files:
# Check if the file is a PNG
if file.endswith(".png"):
# Open the image file
im = Image.open(os.path.join(directory, file))
# Convert the image to JPEG
im = im.convert("RGB")
# Crop the bottom 16 pixels off the image
width, height = im.size
im = im.crop((0, 0, width, height-trim))
# Lower the image quality
im.save(os.path.join(directory, "modified_" + file.replace(".png", ".jpg")), "JPEG", quality=quality)
You will need to edit the file directory to ensure you’re aiming at the correct folder. This script applies modified to the beginning of any changed images and also helps improve the quality of the image, to lower the sizes from 2mb to 100kb.
Removing the DALLE logo is now a quick process and you’re back to using these amazing graphics in no time. For more help with your python, please contact us.
Named Entity Recognition (NER) is a subtask of natural language processing (NLP) that aims to identify and classify named entities in text, such as people, organizations, locations, and dates. The ne_chunk() function from the nltk.chunk module is a method of performing named entity recognition in Python using the Natural Language Toolkit (NLTK) library.
The ne_chunk() function takes a list of POS-tagged tokens as input and returns a tree of named entities. The tree is represented as a nested list of tuples, where each tuple corresponds to a named entity and contains the label of the entity and a list of the words in the entity. For example, the named entity “New York” would be represented as ("GPE", "New York"), where “GPE” is the label for geographical locations.
The ne_chunk() function uses a rule-based approach to named entity recognition, which means that it uses a set of hand-written rules to identify and classify named entities. The rules are based on the POS tags of the words in the text and the context in which they appear. For example, a proper noun (NNP) that appears after the word “of” is likely to be the name of an organization.
One of the main advantages of the ne_chunk() function is its simplicity and ease of use. It requires minimal configuration and can be easily integrated into existing NLP pipelines.
However, the rule-based approach also has some limitations. The accuracy of the named entity recognition depends on the quality and coverage of the rules and can be affected by variations in the text, such as the use of synonyms or nicknames. Additionally, the ne_chunk() function can only recognize a limited set of named entities and doesn’t support fine-grained entity types, such as job titles or product names.
Another limitation of ne_chunk() is that it doesn’t take into account the context in which the named entities appear, which can be important for disambiguating entities and understanding their meaning.
Despite these limitations, the ne_chunk() function can still be useful for basic named entity recognition tasks, such as extracting names of people, organizations, and locations from unstructured text. In addition, it can be used as a starting point for more advanced NER systems or for tasks where high accuracy is not a strict requirement.
Overall, the ne_chunk() function is a simple and easy-to-use method for performing named entity recognition in Python using NLTK. While its accuracy may be limited, it can still be useful for basic NER tasks and as a starting point for more advanced systems.
To add named entity recognition (NER) to the existing code, you can use the ne_chunk() function from the nltk.chunk module, which takes a list of POS-tagged tokens as input and returns a tree of named entities. Here is an example of how to use the ne_chunk() function:
# Import the ne_chunk function from the nltk.chunk module
from nltk import ne_chunk
# Perform named entity recognition on the filtered tokens
named_entities = ne_chunk(filtered_tokens)
# Print the named entities
print(named_entities)
This script uses the ne_chunk() function to perform named entity recognition on the filtered tokens, which are the tokens that have been filtered by POS tags. The function returns a tree of named entities, which you can print to see the recognized entities.
You can also use nltk.ne_chunk() function which take the POS tagged tokens and return the tree of named entities, this function uses the maxent classifier to classify the words.
# Perform named entity recognition on the filtered tokens
named_entities = nltk.ne_ch
Part-of-speech tagging, also known as POS tagging or grammatical tagging, is a method of annotating words in a text with their corresponding grammatical categories, such as noun, verb, adjective, adverb, and so on. This process is important for natural language processing (NLP) tasks such as text classification, machine translation, and information retrieval.
There are two main approaches to POS tagging: rule-based and statistical. Rule-based tagging uses a set of hand-written rules to assign POS tags to words, while statistical tagging uses machine learning algorithms to learn the POS tag of a word based on its context.
Statistical POS tagging is more accurate and widely used because it can take into account the context in which a word is used and learn from a large corpus of annotated text. The most common machine learning algorithm used for POS tagging is the Hidden Markov Model (HMM), which uses a set of states and transition probabilities to predict the POS tag of a word.
One of the most popular POS tagging tools is the Natural Language Toolkit (NLTK) library in Python, which provides a set of functions for tokenizing, POS tagging, and parsing text. NLTK also includes a pre-trained POS tagger based on the Penn Treebank POS tag set, which is a widely used standard for POS tagging.
In addition to NLTK, other popular POS tagging tools include the Stanford POS Tagger, the OpenNLP POS Tagger, and the spaCy library.
POS tagging is an important step in many NLP tasks, and it is used as a pre-processing step for other NLP tasks such as named entity recognition, sentiment analysis, and text summarization. It is a crucial step in understanding the meaning of text, as the POS tags provide important information about the syntactic structure of a sentence.
In conclusion, Part-of-Speech tagging is a technique that assigns grammatical category to words in a text, which is important for natural language processing tasks. Statistical approach is more accurate and widely used, and there are several libraries and tools available to perform POS tagging. It serves as a pre-processing step for other NLP tasks and it is crucial in understanding the meaning of text.

Here is an example of a Python script that uses the Natural Language Toolkit (NLTK) library to perform part-of-speech tagging on the text scraped from a website:
Find the code from the youtube video above, here on github, explained line by line below.
import requests
from bs4 import BeautifulSoup
import nltk
# Work-around for mod security, simulates you being a real user
headers = {
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:55.0) Gecko/20100101 Firefox/55.0',
}
# Scrape the website's HTML
url = "https://dev3lop.com"
page = requests.get(url, headers=headers)
soup = BeautifulSoup(page.content, "html.parser")
# Extract the text from the website
text = soup.get_text()
# Tokenize the text
tokens = nltk.word_tokenize(text)
# Perform part-of-speech tagging on the tokens
tagged_tokens = nltk.pos_tag(tokens)
# Print the tagged tokens
print(tagged_tokens)
This script uses the requests library to scrape the HTML of the website specified in the url variable. It then uses the BeautifulSoup library to extract the text from the HTML. The text is tokenized using the word_tokenize() function from NLTK, and then part-of-speech tagging is performed on the tokens using the pos_tag() function. The resulting list of tagged tokens is then printed to the console.
Filtering out common words
If you’re digging deeper, you may want to see what “NN” for nouns, “VB” for verbs, and “JJ” for adjectives are in usage.
We can quickly filter out the POS tags that are not useful for our analysis, such as punctuation marks or common function words like “is” or “the”. For example, you can use a list comprehension to filter out the POS tags that are not in a certain list of POS tags that you are interested in analyzing:
# List of POS tags to include in the analysis
include_pos = ["NN", "VB", "JJ"]
# Filter the tagged tokens to include only the specified POS tags
filtered_tokens = [(token, pos) for token, pos in tagged_tokens if pos in include_pos]
# Print the filtered tokens
print(filtered_tokens)
Now that you’re done counting occurrences, you can inspect the print of token_counts and notice this method also helped you sort the information from largest to smallest. We hope this lesson on Part-of-Speech Tagging using a Web Scrapped Website is a solution you’re able to take into consideration when generating your next python data pipeline!
