# dstc3

This is a text classification dataset. It is intended for machine learning research and experimentation.

This dataset is obtained via formatting another publicly available data to be compatible with our [AutoIntent Library](https://deeppavlov.github.io/AutoIntent/index.html).

## Usage

It is intended to be used with our [AutoIntent Library](https://deeppavlov.github.io/AutoIntent/index.html):

```python
from autointent import Dataset

dream = Dataset.from_datasets("AutoIntent/dstc3")
```

## Source

This dataset is taken from `marcel-gohsen/dstc3` and formatted with our [AutoIntent Library](https://deeppavlov.github.io/AutoIntent/index.html):


```python
from datasets import load_dataset
from autointent import Dataset

# load original data
dstc3 = load_dataset("marcel-gohsen/dstc3")

# extract intent names
dstc3["test"] = dstc3["test"].filter(lambda example: example["transcript"] != "")
intent_names = sorted(set(name for intents in dstc3["test"]["intent"] for name in intents))
intent_names.remove("reqmore")
dstc3["test"].filter(lambda example: "reqmore" in example["intent"])
name_to_id = {name: i for i, name in enumerate(intent_names)}

# parse complicated dstc format
def transform(example: dict):
return {
"utterance": example["transcript"],
"label": [name_to_id[intent_name] for intent_name in example["intent"] if intent_name != "reqmore"],
}
dstc_converted = dstc3["test"].map(transform, remove_columns=dstc3["test"].features.keys())

# format to autointent.Dataset
intents = [{"id": i, "name": name} for i, name in enumerate(intent_names)]
utterances = []
oos_utterances = []
for rec in dstc_converted.to_list():
if len(rec["label"]) == 0:
rec.pop("label")
oos_utterances.append(rec["utterance"])
else:
utterances.append(rec)
oos_records = [{"utterance": ut} for ut in set(oos_utterances)]
dstc_converted = Dataset.from_dict({"intents": intents, "train": utterances + oos_records})
```
