UIDAI - Address Formatting

I participated in an online hackathon hosted by the Unique Identification Authority of India for solving the problems related to the aadhar card. We solved a problem related to the addresses entered by the users where repetition was the major issue.

I was responsible for implementing a logic to map the given address against the CSV datasheet of the Indian Postal Service to validate the area/city/state address and check if any further changes are needed or not.

Moreover, we achieved the task by using fuzzy logic and the Levenshtein distance Algorithm which is a string-matching algorithm and implemented this in python.

We solved the issues like duplication, spelling correction, and missing fields, and removed special characters from the given address.
