OCR is not something we use very often, but sometimes it is useful or even necessary, when customer send us documents in hard copy or in a scanned graphic format.
The program we have used for the last few years is OmniPage Professional. We recently upgraded from OmniPage 15 to OmniPage 17. My first impressions are, on the whole, positive: OCR accuracy with documents not of the bast quality is improved, the program is much better at recognizing that stray dots on the page are not text (on the flip side, for Italian, this means that sometime the program does not recognize words such as "i" or "il", taking them as noise instead of characters).
An annoying defect I had not seen in the previous version is that the program sometimes puts the recognized characters on the wrong line in the target text.
On the whole, a useful program, and a real life saver when we need to translate repetitive documents that arrive to use in graphic form.
