### Dataset Summary
|
| 11 |
+
|
| 12 |
+
The zip file contains textlines and their annotations from AIDA-project. There are ~ 166k textlines that are mainly in Finnish language, but contain a little Swedish and
|
| 13 |
+
English and little French and German textlines. The textlines contains typewritten and also handwritten lines. Roughly 24 % of the lines are handwritten and the rest are

|
| 15 |
+
|
| 16 |
+
### Supported Tasks

|
| 19 |
+
|
| 20 |

### Languages

### Data Instances
|
| 27 |
+
|
| 28 |
+
The zip file contains two folders. Folder called text_lines contains all the text lines. The other folder called annotations contain the annotations in PaddleOCR format.
|
| 29 |
+
The annotations are divided into train, validation and test sets. In addition to this, the annotations are divided into handwritten, typewritten and ship, which contains
|
| 30 |
+
annotations of ship records that are mainly handwritten. Handwritten and typewritten annotations are also divided into best and semi files. Best means that the annotator has
|
| 31 |
+
understood every letter in the line as semi means that some character are not understood.
|
| 32 |
+
|
| 33 |
+
PaddleOCR format means that the annotations are saved into a txt file containing multiple annotations. One annotations is place per line in the file. First the format
|
| 34 |
+
contains path to the image, then a separating "\t" character and then the transcription. An example of the format is shown below.
|
| 35 |
+
|
| 36 |
+
0001.jpg\tHello World
|
| 37 |
+
0002.jpg\tThis is PaddleOCR format.
