Predict Soft News
Project description
The package provides classifiers for soft news based on the story text and the url structure for both the US and UK news media. We provide also provide a way to infer the ‘kind’ of news—Arts, Books, Science, Sports, Travel, etc.—for the US news media.
Quick Start
>>> import pandas as pd
>>> from notnews import *
>>> # Get help
>>> help(soft_news_url_cat_us)
Help on method soft_news_url_cat in module notnews.soft_news_url_cat:
soft_news_url_cat(df, col='url') method of builtins.type instance
Soft News Categorize by URL pattern.
Using the URL pattern to categorize the soft/hard news of the input
DataFrame.
Args:
df (:obj:`DataFrame`): Pandas DataFrame containing the URL
column.
col (str or int): Column's name or location of the URL in
DataFrame (default: url).
Returns:
DataFrame: Pandas DataFrame with additional columns:
- `soft_lab` set to 1 if URL match with soft news URL pattern.
- `hard_lab` set to 1 if URL match with hard news URL pattern.

Installation
Installation is as easy as typing in:
pip install notnews
API
soft_news_url_cat_us Uses URL patterns in prominent outlets to classify the type of news. It is based on a slightly amended version of the regular expression used to classify news, and non-news in Exposure to ideologically diverse news and opinion on Facebook by Bakshy, Messing, and Adamic in Science in 2015. Our only amendment: sport rather than sports. The classifier success is liable to vary over time and across outlets.
Arguments:
df:
url: column with the domain names/URLs. Default is url
What it does:
converts url to lower case
regex
URL containing any of the following words is classified as soft news: sport|entertainment|arts|fashion|style|lifestyle|leisure|celeb|movie|music|gossip|food|travel|horoscope|weather|gadget URL conta ining any of following words is classified as hard news: politi|usnews|world|national|state|elect|vote|govern|campaign|war|polic|econ|unemploy|racis|energy|abortion|educa|healthcare|immigration
Output:
Given both the regex can return true, the potential set is: soft, hard, soft and hard, or empty string.
By default it creates two columns, `hard_lab` and `soft_lab`
Examples:
>>> import pandas as pd >>> from notnews import soft_news_url_cat_us >>> >>> df = pd.DataFrame([{'url': 'http://nytimes.com/sports/'}]) >>> df url 0 http://nytimes.com/sports/ >>> >>> soft_news_url_cat_us(df) url soft_lab hard_lab 0 http://nytimes.com/sports/ 1 None
pred_soft_news_us: We use data from NY Times to train a model. The function uses the trained model to predict soft news.
Arguments:
df: pandas dataframe. No default.
text: column with the story text.
Functionality:
Normalizes the text and gets the bi-grams and tri-grams
Outputs calibrated probability of soft news using the trained model
Output
Appends a column with probability of soft news (prob_soft_news_us)
Examples:
>>> import pandas as pd >>> from notnews import pred_soft_news_us >>> >>> df = pd.read_csv('notnews/tests/sample_us.csv') >>> df src url text 0 nyt http://www.nytimes.com/2017/02/11/us/politics/...
