Программы OCR с русским языком



2015-August. Possibilities in OCR and server automation:

    1. Output: one raw text OCRed file (including from images)

    2. Zoning: when an original document is intelligently broken into sections (articles/columns in newspapers; images/tables/text)

    3. Structuring: automatic separation of fields: author, title, main text, etc.

    4. Indexing: automated selection of index terms which comes as an addition to the main OCRed text: people/company names, product names, geographic locations, etc.

    5. Data mining: more advanced analysis and processing of OCRed text to establish dependencies, patterns, etc.

    + API

additional idea:

   - provide storage and keyword searching service over OCRed text. On-the-fly database of semi-structured data.. + image of original documents. Tobaccodocuments can serve as an example..

   - provide stable URL to docs;

    + possible back office for manual data structuring and metadata assignment
