Dataset Description

Dataset Summary

This is a dataset for NLG in task-oriented spoken dialogue systems with Czech as the target language. It originated as a translation of the English San Francisco Restaurants dataset by Wen et al. (2015). The domain is restaurant information in Prague, with random/fictional values. It includes input dialogue acts and the corresponding outputs in Czech.

Supported Tasks and Leaderboards

  • other-stuctured-to-text: The dataset can be used to train a model for data-to-text generation: from a desired dialogue act, the model must produce textual output that conveys this intention.

Languages

The entire dataset is in Czech, translated from the English San Francisco dataset by professional translators.

Dataset Structure

Data Instances

Example of a data instance:

{
  "da": "?request(area)",
  "delex_da": "?request(area)",
  "text": "Jakou lokalitu hledáte ?",
  "delex_text": "Jakou lokalitu hledáte ?"
}

Data Fields

  • da: input dialogue act
  • delex_da: input dialogue act, delexicalized
  • text: output text
  • delex_text: output text, delexicalized

Data Splits

The order of the instances is random; the split is roughly 3:1:1 between train, development, and test, ensuring that the different sections don't share the same DAs (so the generators need to generalize to unseen DAs), but they share as many generic different DA types as possible (e.g., confirm, inform_only_match etc.). DA types that only have a single corresponding DA (e.g., bye()) are included in the training set.

The training, development, and test set contain 3569, 781, and 842 instances, respectively.

Dataset Creation

Curation Rationale

While most current neural NLG systems do not explicitly contain language-specific components and are thus capable of multilingual generation in principle, there has been little work to test these capabilities experimentally. This goes hand in hand with the scarcity of non-English training datasets for NLG – the only data-to-text NLG set known to us is a small sportscasting Korean dataset (Chenet al., 2010), which only contains a limited number of named entities, reducing the need for their inflection. Since most generators are only tested on English, they do not need to handle grammar complexities not present in English. A prime example is the delexicalization technique used by most current generators. We create a novel dataset for Czech delexicalized generation; this extends the typical task of data-to-text NLG by requiring attribute value inflection. We choose Czech as an example of a morphologically complex language with a large set of NLP tools readily available.

Source Data

Initial Data Collection and Normalization

The original data was collected from the English San Francisco Restaurants dataset by Wen et al. (2015).

Who are the source language producers?

The original data was produced in interactions between Amazon Mechanical Turk workers and themed around San Francisco restaurants. This data was then translated into Czech and localized to Prague restaurants by professional translators.

Annotations

No annotations.

Personal and Sensitive Information
