News Crawler

This project is an extension of the original project Nespaper3k. The original documentation from the project is still part of this README file and it starts at the heading Newspaper3k: Article scraping & curation.

This code contains extensions in the core part of the crawler, and additional classes for crawling domain specific news.

The main class for crawling news articles is located in the file crawler.py and you can run the crawler by just executing python3 crawler.py. However, before you do that, you need to setup the database, which contain the sources for crawling, and the table where to store the crawled documents.

Database

Before you can use the tool, you need to create a database, to store the crawled articles. The database consists of five tables, which are used from different modules in the whole project. These tables are: - news_source - news_article - annotated_news_article - annotation_error - translation_error

The first two tables are used by this project. The first table news_source contains a list of news domains with their url and the language in which the news articles are written.

The second table, news_article is used to store the crawled text from the news articles, along with some metadata about the news article.

To create the database from the script provided in this project, run the following command:

$./psql -h <HOST_NAME> --port <PORT> -U <USER> -d <DATABASE_NAME> -a -f crawler/database.sql

Note that you have to replace <HOST_NAME>, <PORT>, <USER> and <DATABASE_NAME> with values specific to your PostgreSQL server.

Configuring the database connection

The database connection is configured in the file crawler/database.ini by setting the host, database, username and password.

Running the Crawler

The crawler can be run as a Python script, or you can create a docker image and let the script run in a docker environment continuously. To run it as a Python script use the following code:

$ python3 crawler.py

To run it as docker container, first you need to create the docker image:

$ docker build -t news-crawler:v1 .

And the start the container with:

$ docker run -d --name news-crawler \
        -v /<LOCAL_PATH>/newspaper:/root/.newspaper_scraper \
        news-crawler:v1

Note that you have to setup the variable <LOCAL_PATH> to a path somewhere in your hard disk, to avoid deleting caches for already crawled news articles when you destroy the container.

Newspaper can extract and detect languages seamlessly. If no language is specified, Newspaper will attempt to auto detect a language.

Get it now

Run ✅ pip3 install newspaper3k ✅

NOT ⛔ pip3 install newspaper ⛔

On python3 you must install newspaper3k, not newspaper. newspaper is our python2 library. Although installing newspaper is simple with pip, you will run into fixable issues if you are trying to install on ubuntu.

If you are on Debian / Ubuntu, install using the following:

  • Install pip3 command needed to install newspaper3k package:

    $ sudo apt-get install python3-pip

  • Python development version, needed for Python.h:

    $ sudo apt-get install python-dev

  • lxml requirements:

    $ sudo apt-get install libxml2-dev libxslt-dev

  • For PIL to recognize .jpg images:

    $ sudo apt-get install libjpeg-dev zlib1g-dev libpng12-dev

NOTE: If you find problem installing libpng12-dev, try installing libpng-dev.

  • Download NLP related corpora:

    $ curl https://raw.githubusercontent.com/codelucas/newspaper/master/download_corpora.py | python3

  • Install the distribution via pip:

    $ pip3 install newspaper3k

If you are on OSX, install using the following, you may use both homebrew or macports:

$ brew install libxml2 libxslt

$ brew install libtiff libjpeg webp little-cms2

$ pip3 install newspaper3k

$ curl https://raw.githubusercontent.com/codelucas/newspaper/master/download_corpora.py | python3

Otherwise, install with the following:

NOTE: You will still most likely need to install the following libraries via your package manager

  • PIL: libjpeg-dev zlib1g-dev libpng12-dev
  • lxml: libxml2-dev libxslt-dev
  • Python Development version: python-dev
$ pip3 install newspaper3k

$ curl https://raw.githubusercontent.com/codelucas/newspaper/master/download_corpora.py | python3

Development

If you'd like to contribute and hack on the newspaper project, feel free to clone a development version of this repository locally:
