SciQ - Italian (IT)

This dataset is an Italian translation of SciQ. SciQ is a dataset for scientific questions, which were semi-automatically generated from an existing set of questions. The dataset is designed to test the ability of models to answer questions that require scientific knowledge.

Dataset Details

The dataset consists of science-related questions, where each question is associated with a correct answer and three possible distractors. The task is to predict the correct answer to the question. The dataset also provides a support passage for most questions, which can be used to answer the question.

The dataset includes the following splits:

  • Validation: 960 rows
  • Test: 956 rows

Differences with the original dataset

  • The number of instances in this dataset is smaller than the original dataset due to the translation process, during which some instances were filtered out.

Languages

This dataset is fully parallel between English and Italian. This allows us to have comparable evaluation setups and results across the two languages.

Translation Process

The translation has been carried out using 🍱 OBenTO-LLM, an open-source tool for LLM-based translation. The main motivation for using an open-source LLM is to encourage free, open, reproducible, and transparent research in LLM evaluation. See 🍱 OBenTO-LLM for more details on the translation process.

Model used to translate: [Unbabel/TowerInstruct-7B-v0.2] (https://huggingface.co/Unbabel/TowerInstruct-7B-v0.2)

Other Information

Dataset Format

This is an example that shows the format of the dataset, where:

  • id: a unique ID for each sample;
  • category: type of task;
  • input_text: the original English sentence in the dataset;
  • input_text_translation: the translation of the sentence in Italian;
  • choices: the original English choices;
  • choice_translations: the translation of the choices in Italian;
  • label: the index of the correct answer.
  • metadata: additional information about the question, including the correct answer, the explanation of how to solve the problem, and the annotated explanation.

Example of a question in SciQ

{
  "id": "sciq_2",
  "category": "question",
  "input_text": "A frameshift mutation is a deletion or insertion of one or more of what that changes the reading frame of the base sequence?",
  "input_text_translation": "Una mutazione frameshift è una delezione o un'inserzione di uno o più di cosa che cambia il quadro di lettura della sequenza di basi?",
  "choices": [
    "Nucleotides.",
    "Proteins.",
    "Carotenoids.",
    "Genes."
  ],
  "choice_translations": [
    "Nucleotidi.",

    "Carotenoidi.",
    "Geni."
  ],
  "label": 0,
  "metadata": {
    "passage": "A frameshift mutation is a deletion or insertion of one or more nucleotides that changes the reading frame of the base sequence. Deletions remove nucleotides, and insertions add nucleotides. Consider the following sequence of bases in RNA:.",
    "passage_translation": "Una mutazione di spostamento del marcatore è una eliminazione o un'inserzione di uno o più nucleotidi che cambia il marcatore di lettura della sequenza di basi. Le eliminazioni rimuovono i nucleotidi e le inserzioni ne aggiungono. Considerate la seguente sequenza di basi in RNA:."
