How a Kolkata batch moves through the pipeline

  1. Step 1

    Ingest

    Bulk PDF intake from any source — scans, photos, government portals. Page splitting, de-skew, de-noise.

  2. Step 2

    OCR in the right script

    Models for Devanagari, Telugu, Tamil, Kannada, Malayalam, Bengali, Gujarati, Gurmukhi, Odia, Urdu and Latin scripts, tuned on Indian government and publishing layouts: tables, multi-column, mixed scripts.

  3. Step 3

    Structure to XML

    Fields, tables and hierarchy mapped to your schema — JATS, TEI, DocBook, ONIX, or a custom XSD. Validated on every file.

  4. Step 4

    Quality checks

    Automated confidence scoring plus human review of low-confidence pages. You get an accuracy report, not a promise.

  5. Step 5

    Deliver & search

    XML/EPUB/JSON/CSV delivery, or a ready-made search interface like the one we built for 2002 voter rolls.

Questions from Kolkata clients

Do you have an office in Kolkata?
We work with Kolkata clients remotely and on-site for pickup and scanning coordination. Processing runs on our servers in India; you never courier originals abroad.
Can you handle Bengali documents?
Yes. Bengali OCR is one of our core scripts (Bengali and Latin). We run a free 50-page sample first and send you the accuracy report before any commitment.
What do I get back?
Validated XML in your schema (JATS, TEI, DocBook, ONIX or custom), EPUB 3, JSON or CSV — plus an accuracy report and, if you want, a hosted search interface.
How is pricing worked out?
Per page, by script and scan quality, with a fixed quote after the sample batch. No per-seat software licence.
