Description:

seamster 0.0.1

Seamster

High Performance Fuzzy Business Entity Matching
Motivation
The purpose of this package is to facilitate a broader goal of centralizing and standardizing publicly
available data on businesses. Juniper is doing this because we believe that the key to innovation
in Commercial Insurance underwriting lies in making public data accessible, reliable, and complete.
Features

Built on top of Pandas and Scipy to do parallelized calculation of string similarities.
Extensible Join class allows for custom joins

Installation
Seamster requires Python 3.5 or newer to run.
Python package
You can easily install Seamster using pip:
pip3 install seamster
Manual
Alternatively, to get the latest development version, you can clone this repository and then manually install it:
git clone git@gitlab.com:juniperlabs-foss/seamster.git
cd seamster
python3 setup.py install

Usage
import pandas as pd
from seamster.join_side import JoinSide
from seamster.join import NameZipEntTypeJoin

source1 = {
"id": [1, 2, 3, 4],
"names": [
"Subway",
"Blimpies",
"McDonalds Hamburguesas, Inc.",
"MacDonalds Hamburgers",
],
"zip": [80238, 80238, 80230, 80238],
"entity_type": ["llc", "llc", "corporation", "corporation"],
}

source2 = pd.DataFrame(
{
"id": [5, 6, 7],
"names": ["McDonalds Hamburgers Inc", "Burger King", "Wendys"],
"zip": [80238, 80238, 80230],
"entity_type": ["corporation", "llc", "inc"],
}
)

js_a = JoinSide(
data=pd.DataFrame(source1),
source="a",
entity_name_field="names",
id_field="id",
zip_field="zip",
entity_type_field="entity_type",
)
js_b = JoinSide(
data=pd.DataFrame(source2),
source="b",
entity_name_field="names",
id_field="id",
zip_field="zip",
entity_type_field="entity_type",
)

bs = NameZipEntTypeJoin(join_sides=(js_a, js_b))

df = bs.join(lower_bound=0.8)

print(df.to_dict(orient="records"))

TODO

Create transform class that can permute and enrich the dataframe (e.g., geolocation, )
Support for multiple fuzzy joins
