Radix Analytics Pvt Ltd > Text Analytics > Searchable Contracts for Public Works Authority

Issues & Objectives

To develop ML based system for searching contents in contracts:

  • Contacts are present with the client in pdf format with scanned images
  • We have to convert it into readable formats and then index them in database
  • Our aim is to build a ML based system that can accurately find the search term in headings of the contracts

Results

  • API which takes contact number and search term as an input was built
  • It outputs the potential pages where the term could be found
  • The client’s team then integrates them in their PDF reader to enable direct search and read operations

Challenges

  • The Contacts PDFs needs to be run through an Optical Character Recognition system
  • We are only searching for topics/headings, therefore we only need to extract the headings from the text
  • Handling and Searching in a large amount of data

Solution

  • PDFs need to be OCR’d to load texts in it
  • Headings were extracted from the texts with a high recall using Tika
  • Headings were indexed in solr to determine top results
  • The top results are then passed to ML to determine the best match among them
  • MariaDB (SQL) database is used
  • The deployment framework is Flask API + Gunicorn
