## Dataset Summary
NER-News-BIDataset is a dataset for named entity recognition (NER) in news articles, publicly released by the National Institute of Korean Language in 2023.   
The dataset is labeled with named entities specifically for news data.   
It consists of a total of 150,142 sentences, and entities are categorized into 150 labels for recognition.  

## Languages
Korean  

## Data Structure
DatasetDict({    
    train: Dataset({    
        features: ['input_ids', 'attention_mask', 'labels'],   
        num_rows: 120113   
    })   
    test: Dataset({   
        features: ['input_ids', 'attention_mask', 'labels'],   
        num_rows: 30029   
    })   
})     

### Data Instances
The dataset is provided in text format with train/test sets.   
Each instance represents a news article, and if there is an entity in the sentence, it is appropriately tagged with the corresponding label.   
In cases where a single entity is separated into multiple tokens, the first token is labeled as "B-entity" and the subsequent tokens are labeled as "I-entity" until the end.  

### Data Fields
input_ids: "A processed named entity corpus of news articles constructed in 2022" has been tokenized and represented with numerical values.  
label: Identified a total of 151 entities, including the 0th label (not an entity). If counting both "B-entity" and "I-entity" labels for each entity, there are a total of 301 labels. 
The labeling is done with numerical values.  
The 151 types of labels are as follows:  

|index|0|1|2|3|4|5|6|7|8|9|10|11|12|13|14|15|16|17|18|19|20|21|22|23|24|25|26|27|28|29|30|31|32|33|34|35|36|37|38|39|40|41|42|43|44|45|46|47|48|49|50|51|52|53|54|55|56|57|58|59|60|61|62|63|64|65|66|67|68|69|70|71|72|73|74|75|76|77|78|79|80|81|82|83|84|85|86|87|88|89|90|91|92|93|94|95|96|97|98|99|100|101|102|103|104|105|106|107|108|109|110|111|112|113|114|115|116|117|118|119|120|121|122|123|124|125|126|127|128|129|130|131|132|133|134|135|136|137|138|139|140|141|142|143|144|145|146|147|148|149|150|151|152|153|154|155|156|157|158|159|160|161|162|163|164|165|166|167|168|169|170|171|172|173|174|175|176|177|178|179|180|181|182|183|184|185|186|187|188|189|190|191|192|193|194|195|196|197|198|199|200|201|202|203|204|205|206|207|208|209|210|211|212|213|214|215|216|217|218|219|220|221|222|223|224|225|226|227|228|229|230|231|232|233|234|235|236|237|238|239|240|241|242|243|244|245|246|247|248|249|250|251|252|253|254|255|256|257|258|259|260|261|262|263|264|265|266|267|268|269|270|271|272|273|274|275|276|277|278|279|280|281|282|283|284|285|286|287|288|289|290|291|292|293|294|295|296|297|298|299|300|
