There is no good OCR for languages like Malayalam.

Hi Here are the answers What does "converted to Unicode" mean? Converted from what exactly? Do There is no good OCR for languages like Malayalam. So each scanned image is manually typed and proofread For example, See the 7th page of this book <http://idb.ub.uni-tuebingen.de/opendigi/CiXIV125b#p=7&tab=transcript>. You can see the scan image on the right and the transcribed text for that page on the left in the *Transcript *tab. This is done for 136 books, and total pages on these books are close to 25,700 pages. What would you want the script to do exactly? Pull the files from the Yes, this is what is required. Unicode migration we will handle separately. Shiju Alex On Sun, Dec 2, 2018 at 4:07 PM Andre Klapper &lt;aklapper(a)wikimedia.org&gt; wrote: > Hi, > Great!

The request in this post is not for creating an OCR for any language script; but to migrate certain Public Domain book scans from Tuebingen digital library to Wikimedia Commons. Also there is another task of migrating *already proofread Unicode text* to Wikisource. But to take up the Unicode migration first the scans need to be in Commons. I am making this request only because of the huge amount of pages that we need to handle. If it was just few hundreds of pages volunteers would have manually done it.
