## Dataset Description |
|
|
|
### Dataset Summary |
|
|
|
The *Historical Danish handwriting* dataset is a Danish-language dataset containing more than 11.000 pages of transcribed and proofread handwritten text. |
|
|
|
The dataset currently consists of the published minutes from a number of City and Parish Council meetings, all dated between 1841 and 1939. |
|
|
|
|
|
### Languages |
|
|
|
All the text is in Danish. The BCP-47 code for Danish is da. |
|
|
|
|
|
## Dataset Structure |
|
|
|
### Data Instances |
|
|
|
Each data instance represents a single scanned, segmented and transcribed physical page with handwritten text. |
|
|
|
|
|
### Data Fields |
|
|
|
- `image`: a jpeg image containing a scan of the original physical page |
|
- `doc_id`: internal id of parent document (collection of single pages) to which the page belongs |
|
- `sequence`: the specific pagenumber of the page within the parent document |
|
- `alto`: an xml-encoded string containing layout and content information of the physical page, stored in [ALTO XML, version 4.2](https://www.loc.gov/standards/alto/v4/alto-4-2.xsd) |
|
- `page`: an xml-encoded string containing layout and content information of the physical page, stored in [PAGE XML, version 2013-07-15](https://www.primaresearch.org/schema/PAGE/gts/pagecontent/2013-07-15/pagecontent.xsd) |
|
|
|
To uniquely identify a single page within the dataset, one can use the `doc_id` integer in combination with the `sequence` integer. |

## Dataset Creation |
|
|
|
### Curation Rationale |
|
|
|
The dataset originates from a need to make physical public protocols discoverable via fulltext search and filtering. |
|
|
|
|
|
### Source Data |
|
|
|
The source data consists of written minutes from different City and Parish Council meetings, dating from 1841 to 1939. |
|
|
|
|
|
#### Initial Data Collection and Normalization |
|
|
|
The original physical minutes where collected and curated as part of the legal mandate of the Public City Archives in Denmark. |
|
|
|
|
|
#### Who are the source language producers? |
|
|
|
The digitized and transcribed minutes were originally written by the secretaries of the individual City and Parish Councils. |
|
|
|
The layout segmentation and transcription of the digitized minutes is primarily done by volenteers and employees at the participating Danish city archives. |
|
|
|
All layout segmentation and transcription is done using the Transkribus platform, either through the desktop client or via the web-based interface. |
|
|
|
|
|
### Annotations |
|
|
|
#### Annotation process |
|
|
|
When using the Transkribus clients to segment and transcribe the scanned pages, it is possible to add TEI-tags to single words or whole paragraphs. |
|
|
|
These annotations have not been applied in any consistent manner, and should be ignored. |
|
|
|
|
|
#### Who are the annotators? |
|
|
|
The annotations are produced inside Transkribus by the volunteers and employees transcribing and proofreading the documents. |
|
|
|
|
|
### Personal and Sensitive Information |
|
|
|
No efforts were made to anonymize the data. |
|
|
|
The dataset might contain data that can be considered sensitive (e.g., data that reveals racial or ethnic origins, sexual orientations, religious beliefs, political opinions or union memberships, or locations; financial or health data; biometric or genetic data; forms of government identification, such as social security numbers; criminal history). |
|
|
|
|
|
## Additional Information |
|
|
|
### Dataset Curators |
|
|
|
The Danish handwriting dataset is curated by Aarhus City Archives, Denmark. |
|
|
|
