+<!--- **Homepage:**  --->
+- **Repository:** 
+https://github.com/ltgoslo/norec_tsa
+- **Paper:** 
+[A Fine-Grained Sentiment Dataset for Norwegian](https://aclanthology.org/2020.lrec-1.618/)

+- **Point of Contact:** 
+--->
+
+### Dataset Summary
+The dataset contains tokenized Norwegian sentences where each token is tagged for sentiment expressed towards that token. The dataset is derived from the manually annotated [NoReC_fine](https://github.com/ltgoslo/norec_fine) with rich annotations for each sentiment expression in the texts.  
+The texts are a subset of the Norewegian Review Corpus  [NoReC](https://github.com/ltgoslo/norec).
+
+### Supported Tasks and Leaderboards
+[NorBench](https://github.com/ltgoslo/norbench) provides TSA evaluation scripts using this dataset, and a leaderboard comparing large language models for downstream NLP tasks in Norwegian.  
+
+### Languages
+Norwegian: Predominantly Bokmål written variant.

+
+## Dataset Structure
+The dataset comes in two flavours:
+- `binary` configuration yields labels with binary Positive / Negative sentiment description
+- `intensity` configuration yields labels with additional sentiment intensity, 1: Slight, 2: Standard, and 3: Strong.  
+
+The config is mandatory when loading the dataset and can be passed as a second positional parameter, e.g. `tsa_data = load_dataset("ltg/norec_tsa", "binary")`
+The dataset comes with predefined train, dev (vallidation) and test splits. 
+
+
+### Data Instances
+Config "binary" example instance:
+```
+{'idx': '701363-08-02',
+ 'tokens': ['Vi', 'liker', 'det', '.'],
+ 'tsa_tags': ['O', 'O', 'B-targ-Positive', 'O']}
+```
+Config "intensity"  example instance:
+```
+{'idx': '701363-08-02',
+ 'tokens': ['Vi', 'liker', 'det', '.'],
+ 'tsa_tags': ['O', 'O', 'B-targ-Positive-2', 'O']}
+```
+
+
+
+### Data Fields
+- idx(str): Unique document-and sentence identifier from [NoReC_fine](https://github.com/ltgoslo/norec_fine). The 6-digit document identifier can also be used to look up the text and its metadata in [NoReC](https://github.com/ltgoslo/norec).
+- tokens: (List[str]): List of the tokens in the sentence
+- tsa_tags: (List[str]): List of the tags for each token in BIO format. There is no integer representation of these in the dataset.
+
+
+
+
+### Data Splits
+```
+DatasetDict({
+    test: Dataset({
+        features: ['idx', 'tokens', 'tsa_tags'],
+        num_rows: 1272
+    })
+    train: Dataset({
+        features: ['idx', 'tokens', 'tsa_tags'],
+        num_rows: 8634
+    })
+    validation: Dataset({
+        features: ['idx', 'tokens', 'tsa_tags'],
+        num_rows: 1531
+    })
+})
+```
+
+## Dataset Creation
+
+### Curation Rationale
+The sentiment expressions and targets are annotated in NoReC_fine according to its  [annotation guidelines](https://github.com/ltgoslo/norec_fine/blob/master/annotation_guidelines/guidelines.md)
+
+Since a sentiment target may be the target of several sentiment expressions, these are resolved to a final sentiment polarity (and intensity) using the conversion script in [NoReC_tsa](https://github.com/ltgoslo/norec_tsa). There is no "mixed" sentiment category. When a target is the receiver of both positive and negative sentiment, the strongest wins. If a tie, the last sentiment wins.

+### Discussion of Biases
+The professional review texts in NoReC that NoReC_tsa is a subset from, are from a set number of Norwegian Publishing channels and from a set timespan that can be explored in the [NoReC metadata](https://raw.githubusercontent.com/ltgoslo/norec/master/data/metadata.json). Both language usage and sentiments expressed could have been more diverse with a more diverse set of source texts.
