What is this article about?
A canvass of deaths in the Conemaugh Valley flood found the loss of life much smaller than first estimated, with estimates ranging from about 5,000 to nearly 10,000, though exact figures remained uncertain.
Quality green show the numbers
Measured from the scan
— how cleanly the OCR engine read the characters
- Mean ink quality
- 99.0% The length-weighted average confidence across the OCR lines — the mean of exactly the per-line scores whose tails the two figures below report. Typical is 99%.
- Illegible ink
- 0.0% Text sitting in OCR-detected lines that scored below 80% confidence — very shaky reads. Weighted by line length, so one long bad line counts for more than a short one.
- Uncertain ink
- 0.0% Text in lines that scored 80–90% — somewhat shaky reads.
- Matches source
- 98.6% How closely the served text matches the raw OCR of the same boxes, letter by letter, after collapsing spacing and case. This measures agreement, not correctness: the OCR is often wrong and the extractor corrects it, so 100% does not mean perfect, and a low figure usually means poor scan text was rewritten rather than that text was lost (length vs source shows loss).
- Length vs source
- 99.0% Below 100% means text was dropped from the OCR; above means text was added to make it read.
Assembled by the extraction model
— whether the stitched-together text holds up; catches layout and segmentation errors, which the scores above cannot see
- Transcription confidence
- 98.0% (typical 96%) How cleanly the extractor could assemble what it was given. Low here with clean ink scores points at layout analysis — the characters were read correctly but grouped or ordered wrongly.
- Comprehension
- 95.0% Whether the piece reads coherently start to finish. Can stay high while transcription confidence drops, when only part of the component is affected.
Full Text
The Death Rate in the Conemaugh Valley.
The work of ascertaining the exact number of lives lost in the recent terrible flood which swept through the Conemaugh Valley is now probably nearly as complete as it will ever be. The canvass has shown that the number of those lost was very much smaller than was at first estimated.
Mr. Clark, who made a directory of Johnstown in this year, and who is therefore competent to some extent to speak upon the subject, thinks that not more than 5,000 lives were lost. Another authority of some standing puts the total 2,000 below this. And yet two or three days ago the doctors working at Johnstown agreed that the list of dead would be not less than 10,000. There are various other estimates, but the total loss of life in the valley, judging from the prevailing opinion among those engaged in the work of registration, will not fall far below 10,000.
