lore-iris 0.0.1b0

Programmatic access to thousands of public documents.

Installation

You can install Lore's Iris API with pip.

pip install lore-iris

The API has been tested with python 3.8.

Setup

In order to use Iris you need to register for a free Iris API account. After registration you can access your token at https://api.iris.lore.ai/user.

You will be prompted to enter this token when you first use the API:

>>> from lore.iris import Client
>>> client = Client()
>>> results = client.search(docset_name="NEWS", query_string="covid")
Authorization failed.  Visit http://api.iris.lore.ai//user to get your token and then update your iris.yaml
Token: 
Updated to new token
Config file saved to /home/<username>/.config/iris/iris.yaml
>>> len(results)
100

Note that the initial search query will run upon entering a valid token.

Basic Usage

To access the API:

from lore.iris import Client
client = Client()

# run a search
results = client.search(
		docset_name="NEWS",
		query_string="covid",
		fuzzy=True
		)

To see the number of results:

# check number of results
print(len(results))

A "fuzzy" query will generally include more terms than the original search string:

>>> print(results.terms)
['covid', 'coronavirus', 'pandemic', 'covid-19', 'covid 19']

The results object is an iterator:

# get first result
first = next(results)
print(first)

You can iterate through all results but note that this will automatically generate additional queries to page through all results (by default a search generates max 100 results returned in pages of size 10):

# get all results
# NOTE: this will automatically fire additional paging queries
for idx,r in enumerate(results):
	print(f"{idx}. {r['display_name']} (lang [{r['language']}], {r['num_pages']} pages)")

Config

Iris reads its configuration from the file .config/iris/iris.yaml in your home directory:

irisapi:
    server: http://api.iris.lore.ai/
    token: <API_TOKEN>
    version: '0.1'

If this file is missing, Iris will use a default configuration without any token. If you try to access the API with this configuration you will be prompted to visit:

https://api.iris.lore.ai/user

where you will see your token. Copy this into the prompt and Iris will save your updated config file to .config/iris/iris.yaml in your homedir.

Testing
