PaddleOCR format means that the annotations are saved into a txt file containing multiple annotations. One annotations is placed per line in the file. First, the format
|
| 34 |
+
contains a path to an image, then a separating "\t" character and then the transcription. An example of the format is shown below.

## Dataset Creation
|
| 53 |
|
| 54 |
### Source Data
|
| 55 |
|
| 56 |
+
The data is collected from Central Archives for Finnish Business (ELKA). It consists of various document types including letters, ship records, business publications etc. It
|
| 57 |
+
includes correspondence between companies, organizations and the public.
|
| 58 |
|
| 59 |
### Who are the source language producers?
|
| 60 |
|
| 61 |
+
Given the various types of archival material used in annotation, the scope of producers of the original texts is broad. It includes private individuals and employees of
|
| 62 |
+
different companies.
|
| 63 |
+
|
| 64 |
### Annotations
|
| 65 |
|
| 66 |
+
The textlines were first cropped out of the original image and then transcribed. If the transcription was unclear, the annotator marked it as either "somewhat unclear" or
|
| 67 |
+
"unclear". Unclear images were discarded, but the "somewhat discarded" images are presented here as in the "semi" annotation files. The rough estimate for "somewhat
|
| 68 |
+
unclear" class is that less than 100% and more than 50% of the characters are unclear.
|
| 69 |
+
|
| 70 |
### Who are the annotators?
|
| 71 |
|
| 72 |
+
Annotators were employees of National Archives of Finland and ELKA.
|
| 73 |
+
|
| 74 |
### Personal and Sensitive Information
|
| 75 |
|
| 76 |
+
The dataset is not anonymized, so individuals' names can be found in the dataset.
