PDF-Querying-using-TF-IDF-from-Scratch

Given a set of PDFs and the query, the most relevant pdf can be found with the help of TF-IDF. The code has not used any library to implement TF-IDF

Explanation

The code only uses pdfminer and glob libraries to read pdf and traverse a directory for pdf. The Tf-idf is done manually without using any library. To understand the code, please read the comments in the code.
