qrator

This project scrapes data from various news feeds.

Steps to help you get started

Requirements

• Install devel packs:

  • On Fedora/RHEL: # yum install libxslt-devel python-devel
  • On Ubuntu: # apt-get install libxml2-dev libxslt1-dev python-dev

• Install pip and virtualenv # yum/apt-get install python-pip; pip install virtualenv

• Go to project root and run # virtualenv venv; sourve venv/bin/activate

• Install requirements: $ pip install -r requirements.txt

• scrapy (0.23 preferred) and scrapyd (http://scrapyd.readthedocs.org/en/latest/install.html).

• Elasticsearch instance running on port 9200

• Ensure 'scrapyd' is running: $ sudo service scrapyd start

  • Note: refer execution steps below if you get error here.

Execution steps

• If you haven't deployed the project yet, then go to project root and run:

$ scrapyd-deploy 

• If you aren't running scrapyd as a service, and just ran the above command, you'll get an error^^:

Deploying to project "qrator" in http://localhost:6800/addversion.json
Deploy failed: <urlopen error [Errno 111] Connection refused>

• ^To avoid this, open two terminals:

  1. In one of them, run :

     $ scrapyd
     

  2. In the second one:

     $ scrapyd-deploy          
     

• scrapyd-deploy works directly because the config is already defined in scrapy.cfg file. Else, one has to run:

  $ scrapyd-deploy default -p qrator 
  

• For various scheduling/crawl commands, check scheduler/

NOTE

• News sources include major agencies like DiscoverMag, HN, NYTimes, HBR, TechCrunch and so on..

• http://localhost:6800/ -> Default scrapyd URL

• http://doc.scrapy.org/en/latest/topics/architecture.html Scrapy Architecture

• Refer to TODO.md for current project status.

GUIDELINES

• While mapping fields from crawled data, in the spiders, try to keep the field names unique. For example:

  1. pubDate:updated carries same relation as 'published'
  2. summary is same as description.
  3. and so on.. Refer to current items.py
