What are the functions?

Cellar Extractor

1. get_cellar
Gets all the ECLI data from the eurlex sparql endpoint and saves them in the CSV or JSON format, in-memory or as a saved file.

2. get_cellar_extra
Gets all the ECLI data from the eurlex sparql endpoint, and on top of that scrapes the eurlex websites to acquire the full text, keywords, case law directory code and eurovoc identifiers. The full text is returned as a JSON file, rest of data as a CSV. Can be in-memory or as saved files.

ECHR - Work in progress

Rechtspraak - rechtspraak_extractor

What are the parameters?

1. get_cellar
Parameters:
• max_ecli: int, optional
Maximum amount of ECLIs to retrieve
Default: 100
• sd: date, optional, default '2022-05-01'
The start publication date (yyyy-mm-dd)
• ed: date, optional, default current date
The end publication date (yyyy-mm-dd)
• save_file: ['y', 'n'],optional, default 'y'
Save data as in a data folder, or return in-memory
• file_format: ['csv', 'json'],optional, default 'csv'
Returns the data as a JSON/dictionary, or a CSV/Pandas Dataframe object.
2. get_cellar_extra
ed=None, save_file='y', max_ecli=100, sd="2022-05-01",threads=10
• max_ecli: int, optional
Maximum amount of ECLIs to retrieve
Default: 100
• sd: date, optional, default '2022-05-01'
The start publication date (yyyy-mm-dd)
• ed: date, optional, default current date
The end publication date (yyyy-mm-dd)
• save_file: ['y', 'n'],optional, default 'y'
Save the full text of cases as JSON file / return as a dictionary and save the rest of the data as a CSV file / return as a Pandas Dataframe object
• threads: ['csv', 'json'],optional, default 'csv'
Extracting the additional data takes a lot of time. The use of multi-threading can cut down this time. Even with this, the method may take a couple of minutes for a couple of hundred cases. A maximum number of 15 recommended, as this method may also affect the devices internet connection.
Default: 100

Examples

import cellar_extractor as cell

Below are examples for in-file saving:

cell.get_cellar(save_file='y', max_ecli=200, sd='2022-01-01', file_format='csv')
cell.get_cellar_extra(max_ecli='100, sd='2022-01-01', threads=15)

Below are examples for in-memory saving:

df = cell.get_cellar(save_file='n', file_format='csv', sd='2022-01-01', max_ecli=1000)
df,json = cell.get_cellar_extra(save_file='n', max_ecli=1000, sd='2022-01-01', threads=15)
