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
- 98.95% 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
- 99.3% 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
- 95.0% (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.

Rail Road in the British Provinces.—The Canadians are pressing the construction of a great railway from Halifax to Detroit. Its proposed route is via the cities of St. John and Quebec, and along the valleys of the St. Johns and St. Lawrence. Efforts are to be made to procure a grant of £7,000,000 sterling from Parliament; and in case of success, eminent English capitalists stand ready to invest their funds in the enterprise.
