## Dataset Description

### Dataset Summary

- Dataset for Natural Language Inference in Hindi Language. Hindi Discourse Analysis (HDA) Dataset consists of textual-entailment pairs.
- Each row of the Datasets if made up of 4 columns - Premise, Hypothesis, Label and Topic.
- Premise and Hypothesis is written in Hindi while Entailment_Label is in English.
- Entailment_label is of 2 types - entailed and not-entailed.
- Entailed means that hypotheis can be inferred from premise and not-entailed means vice versa
- Dataset can be used to train models for Natural Language Inference tasks in Hindi Language.

### Supported Tasks and Leaderboards

- Natural Language Inference for Hindi

### Languages

- Dataset is in Hindi

## Dataset Structure

- Data is structured in TSV format. 
- train, test and dev files are in seperate files


### Dataset Instances

An example of 'train' looks as follows.

```
{'hypothesis': 'यह एक वर्णनात्मक कथन है।', 'label': 1, 'premise': 'जैसे उस का सारा चेहरा अपना हो और आँखें किसी दूसरे की जो चेहरे पर पपोटों के पीछे महसूर कर दी गईं।', 'topic': 1}


```
### Data Fields

- Each row contatins 4 columns - premise, hypothesis, label and topic.

### Data Splits

- Train : 31892
- Valid : 9460
- Test : 9970

## Dataset Creation

- We employ a recasting technique from Poliak et al. (2018a,b) to convert publicly available Hindi Discourse Analysis classification datasets in Hindi and pose them as TE problems
- In this recasting process, we build template hypotheses for each class in the label taxonomy
- Then, we pair the original annotated sentence with each of the template hypotheses to create TE samples.
- For more information on the recasting process, refer to paper https://www.aclweb.org/anthology/2020.aacl-main.71

### Source Data

Source Dataset for the recasting process is the BBC Hindi Headlines Dataset(https://github.com/NirantK/hindi2vec/releases/tag/bbc-hindi-v0.1)

#### Initial Data Collection and Normalization

-  Initial Data was collected by members of MIDAS Lab from Hindi Websites. They crowd sourced the data annotation process and selected two random stories from our corpus and had the three annotators work on them independently and classify each sentence based on the discourse mode.
- Please refer to this paper for detailed information: https://www.aclweb.org/anthology/2020.lrec-1.149/
- The Discourse is further classified into "Argumentative" , "Descriptive" , "Dialogic" , "Informative"  and  "Narrative" - 5 Clases.

#### Who are the source language producers?

Please refer to this paper for detailed information: https://www.aclweb.org/anthology/2020.lrec-1.149/

### Annotations

#### Annotation process

Annotation process has been described in Dataset Creation Section.

#### Who are the annotators?

Annotation is done automatically by machine and corresponding recasting process.

### Personal and Sensitive Information

No Personal and Sensitive Information is mentioned in the Datasets.

## Considerations for Using the Data

Pls refer to this paper: https://www.aclweb.org/anthology/2020.aacl-main.71

### Discussion of Biases

No known bias exist in the dataset.
Pls refer to this paper: https://www.aclweb.org/anthology/2020.aacl-main.71

### Other Known Limitations

No other known limitations . Size of data may not be enough to train large models

    abstract = "An NLP model{'}s ability to reason should be independent of language. Previous works utilize Natural Language Inference (NLI) to understand the reasoning ability of models, mostly focusing on high resource languages like English. To address scarcity of data in low-resource languages such as Hindi, we use data recasting to create NLI datasets for four existing text classification datasets. Through experiments, we show that our recasted dataset is devoid of statistical irregularities and spurious patterns. We further study the consistency in predictions of the textual entailment models and propose a consistency regulariser to remove pairwise-inconsistencies in predictions. We propose a novel two-step classification method which uses textual-entailment predictions for classification task. We further improve the performance by using a joint-objective for classification and textual entailment. We therefore highlight the benefits of data recasting and improvements on classification performance using our approach with supporting experimental results.",
