Indeed Scrapper

Scrapper and Parser for Indeed Jobs and Resumes using Python, BeautifulSoup and Selenium/Requests and storing and manipulating data using mongodb

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• Python 2.7
• Virtualenv
• MongoDb

Setup the project

• Clone the Repository

$ git clone https://github.com/shiv-param/indeed_scrapper

• Create your virtual environment

$ virtualenv venv
$ source venv/bin/activate

• Go to the scrapper/ directory

$ cd scrapper

• Install all the libraries required

$ pip install -r requirements.txt

• If you are going to use Selenium for scrapping (Recommended for Resumes), you need to download either of Chrome, Firefox or PhantomJS Webdrivers and save them into tools/ directory and add their path to your Environemnt's PATH variable.

• Make a file in your scrapper/ directory named local_config.py and add the configuration parameters provided in config.py to this file. We are going to change these paramters according to the requirements of the problem.

Now we are ready to change the configuration paramters and run the project.

Note: Do not push your webdrivers and local_config.py to git

Preparing your QuerySet

If we see the url for a jobs/resumes results page, for example

For Jobs: https://www.indeed.co.in/jobs?q=Android&l=Bangalore
For Resumes: https://www.indeed.com/resumes?q=Android&l=Hyderabad%2C+Telangana

We will find out that the urls are constructed as following:

For Jobs: <job_base_url>?<query1_key>=<query1_value>&<query2_key>=<query2_value>....
For Resumes: <resume_base_url>?<query1_key>=<query1_value>&<query2_key>=<query2_value>....

So according to the pattern, The following paramters of our local_config.py file will be set as:

JOB_BASE_URL = "https://www.indeed.co.in/jobs"
RESUME_BASE_URL = "https://www.indeed.com/resumes"
JOB_QUERIES_COLUMNS = ["q", "l"]
RESUME_QUERIES_COLUMNS = ["q", "l"]

And we will be setting the values for these query_keys in a sepeate csv file which we are going to place in our tools/data/ directory and update the following parameters of our local_config.py file:

JOB_QUERIES_INPUT_CSV_PATH = "../tools/data/job_queries.csv"
RESUME_QUERIES_INPUT_CSV_PATH = "../tools/data/resume_queries.csv"

Please refer to queries_template.csv to know the format of the csv.

Now we are ready with our QuerySet for the project.

Note: Do not push your queries.csv to git.

Understanding the Configuration

To select for which scrapping (Jobs or Resumes or both) you are going to run the code, change the following parameters in our local_config.py:

FOR_RESUME = False
FOR_JOB = False

Webdriver Settings

If you are going to use Selenium, change the following parameters in our local_config.py:

WEBDRIVER_REQUIRED = True
WEBDRIVER_TYPE = "chrome"   # Use 'firefox' and 'phantom' for Firefox and PhantomJS Webdrivers respectively
WEBDRIVER_EXECUTABLE_PATH = "path to your webdriver"
MAX_TABS = 10   #Maximum no of tabs you want to allow the code to open at a time

In case if you are scrapping for Resume, we recommend you to use the login feature as number of records are limited to 1000 for resumes in case of no login and 5000 in case of login. For this, change the following parameters in our local_config.py:

LOGIN_REQUIRED = True
LOGIN_URL = "https://secure.indeed.com/account/login"
LOGIN_DETAILS = [  ## List of login credentials eg [{'username': 'someone@example.com', 'password': 'password'} ... ]
    {
        'username': 'someone@example.com',
        'password': 'password'
    }
]

Multiprocessing Settings

In case if you want to use Multiprocessing while scrapping and parsing, change the following parameters in our local_config.py:

MULTIPROCESS_REQUIRED = True
MULTIPROCESS_TYPE = "sequential"  # if you want to run jobs for Job and Resume parallely then 'shared'. Otherwise 'sequential'. By default 'sequential'
NO_OF_PROCESSES = 10

Database Settings

Set up your mongodb database. Create your collections for queries, jobs and resumes. Change the following database parameters in our local_config.py for database support:

HOST = "" # Your DB host
PORT = "" # Your DB port
DB_NAME = "" # Your DB name
COL_QUERIES = "" # Your Queries Collection Name
COL_JOBS = "" # Your Jobs Collection Name
COL_RESUMES = "" # Your Resume Collection Name

Now we are ready with our configuration for the project.

Execution

The basic flow of our codes is:

Add Queries to DB -> Run Link Extraction -> Run HTML Extraction -> Run HTML Parser

Assuming you have already configured your local_settings.py and queries.csv,

• To add queries to DB:

$ cd scrapper/
$ python queries_addition.py

• To run link extraction:

$ cd scrapper/
$ python link_extractor.py

• To run html extraction:

$ cd scrapper/
$ python html_extractor.py

• To run html parsing:

$ cd scrapper/
$ python html_parser.py

Note: Run python status.py to know the status of your execution process.

Final Data
