A year later.... it is no longer confined to OCR and indexing of obituaries. FS is now trying it on other records. I am currently looking at church records from the 1800s in the Philippines "indexed by computer". EVERY ONE of them has at least one transcription error. They also miss names that are spread across two lines (which happens regularly). It regularly fails to correctly identify the relationship of the principal person to other people in the record. It also indexes the names of public officials and priests, which usually have little genealogical value, which then just end up cluttering the index and source links.
Furthermore, if you attach one of these records as a source, the source detail does NOT show: (1) event type, (2) event date, (3) event place, even though that data has been captured. You have to review the attachment in the source linker and open the primary person's detail in order to see this information.
In my opinion, indexes done solely by computer, especially for handwritten text, are not yet ready to released directly for use. Better to have the computer do a first pass in the two-step indexing process, and then have a human review it.
My guess is that is the index editing tool is meant to not just correct individual records but also:
There are simply too many historical records waiting for processing, to do them all entirely by hand. And the backlog must be growing rapidly.
Machine intelligence and OCR is always a moving target
but one should consider the fact that the OCR technology that was used to transcribe the specific newspaper article could have occurred 20 years ago (originally) and has never changed since then (the transcription) . . . .
and comparing that technology to what is available today can be like night and day.
its not always easy to judge when something that we see today that turned out bad -
may have been the result of something that happened 20 years ago - or maybe more recent but with technology that was 20 year old technology.
so its not always easy to judge todays technology on what you see in a specific item today - when you don't know when and how it took place.
