| ### Dataset Summary | |
| SwedMedNER is Named Entity Recognition dataset on medical text in Swedish. It consists three subsets which are in turn derived from three different sources respectively: the Swedish Wikipedia (a.k.a. wiki), Läkartidningen (a.k.a. lt), and 1177 Vårdguiden (a.k.a. 1177). While the Swedish Wikipedia and Läkartidningen subsets in total contains over 790000 sequences with 60 characters each, the 1177 Vårdguiden subset is manually annotated and contains 927 sentences, 2740 annotations, out of which 1574 are _disorder and findings_, 546 are _pharmaceutical drug_, and 620 are _body structure_. | |
| Texts from both Swedish Wikipedia and Läkartidningen were automatically annotated using a list of medical seed terms. Sentences from 1177 Vårdguiden were manuually annotated. | |
| ### Supported Tasks and Leaderboards | |
| Medical NER. | |
| ### Languages | |
| Swedish (SV). | |
| ## Dataset Structure | |
| ### Data Instances | |
| Annotated example sentences are shown below: | |
| ``` | |
| ( Förstoppning ) är ett vanligt problem hos äldre. | |
| [ Cox-hämmare ] finns även som gel och sprej. | |
| [ Medicinen ] kan också göra att man blöder lättare eftersom den påverkar { blodets } förmåga att levra sig. | |
| ``` | |
| Tags are as follows: | |
| - Prenthesis, (): Disorder and Finding | |
| - Brackets, []: Pharmaceutical Drug | |
| - Curly brackets, {}: Body Structure | |
| Data example: | |
| ``` | |
| In: data = load_dataset('./datasets/swedish_medical_ner', "wiki") | |
| In: data['train']: | |
| Out: | |
| Dataset({ | |
| features: ['sid', 'sentence', 'entities'], | |
| num_rows: 48720 | |
| }) | |
| In: data['train'][0]['sentence'] | |
| Out: '{kropp} beskrivs i till exempel människokroppen, anatomi och f' | |
| In: data['train'][0]['entities'] | |
| Out: {'start': [0], 'end': [7], 'text': ['kropp'], 'type': [2]} | |
| ``` | |
| ### Data Fields | |
| - `sentence` | |
| - `entities` | |
| - `start`: the start index | |
| - `end`: the end index | |
| - `text`: the text of the entity | |
| - `type`: entity type: Disorder and Finding (0), Pharmaceutical Drug (1) or Body Structure (2) | |
| ### Data Splits | |
| In the original paper, its authors used the text from Läkartidningen for model training, Swedish Wikipedia for validation, and 1177.se for the final model evaluation. | |
| ## Dataset Creation | |
| ### Curation Rationale | |
| ### Source Data | |
| - Swedish Wikipedia; | |
| - Läkartidningen - contains articles from the Swedish journal for medical professionals; | |
| - 1177.se - a web site provided by the Swedish public health care authorities, containing information, counselling, and other health-care services. | |

| ### Annotations | |
| #### Annotation process | |
| - A list of seed terms was extracted using SweMeSH and SNOMED CT; | |
| - The following predefined categories was used for the extraction: disorder & finding (sjukdom & symtom), pharmaceutical drug (läkemedel) and body structure (kroppsdel) | |
| - For _Swedish Wikipedia_, an initial list of medical domain articles were selected manually. These source articles as well as their linked articles were downloaded and automatically annotated by finding the aforementioned seed terms with a context window of 60 characters; | |
| - Articles from the _Läkartidningen_ corpus were downloaded and automatically annotated by finding the aforementioned seed terms with a context window of 60 characters; | |
| - 15 documents from _1177.se_ were downloaded in May 2016 and then manually annotated with the seed terms as support, resulting 2740 annotations. | |
