ruWorldTree

Task Description

RuWorldTree is a QA dataset with multiple-choice elementary-level science questions that evaluate the understanding of core science facts. The set is created based on the original English WorldTree dataset that provides a corpus of explanation graphs for elementary science questions. The set is a part of the TAPE benchmark that was redesigned to an instruction-based format and filtered.

Keywords: Logic, Reasoning, World Knowledge, Facts

Motivation

The WorldTree design was initially proposed in [1]. The WorldTree dataset starts the triad of the Reasoning and Knowledge tasks. The data includes the corpus of factoid utterances of various kinds, complex factoid questions, and a corresponding causal chain of facts from the corpus, resulting in a correct answer. The Russian RuWorldTree is an analog of WorldTree and is a part of the TAPE benchmark [2] that was redesigned to instruction format and filtered.

Dataset Description

Data Fields

• meta is meta-information about the task:
  • id is an integer containing the unique number of a sample;
  • exam_name is information about the source exam;
  • school_grade is the difficulty level;
  • knowledge_type is the type of knowledge one needs to solve the task;
• instruction is the instructional prompt specified for the current task;
• inputs is a dictionary containing the following input information:
  • question is the question of the test;
  • option_a is the option A;
  • option_b is the option B;
  • option_c is the option C;
  • option_d is the option D;
• outputs is the correct answer, which can be the following string values: "A", "B", "C", "D".

Prompts

We prepared ten different prompts of various difficulties for this task.

Examples of prompts are given below:

"{question}\nA. {option_a}\nB. {option_b}\nC. {option_c}\nD. {option_d}\nКакой ответ является правильным? В качестве ответа запишите только букву верного варианта: A, B, C или D без дополнительных объяснений.\nОтвет:"

"Опираясь на логику и общеизвестные факты, ответьте на вопрос: {question}\nA. {option_a}\nB. {option_b}\nC. {option_c}\nD. {option_d}\nВ качестве ответа запишите только букву верного варианта: A, B, C или D без дополнительных объяснений.\nОтвет:"

Dataset Creation

The questions for the dataset are taken from the original WorldTree dataset, which was sourced from the AI2 Science Questions V2 corpus, consisting of both standardized exam questions from 12 US states, and the AI2 Science Questions Mercury dataset, a set of questions licensed from a student assessment entity. The dataset mainly consists of automatic translation of the English WorldTree Corpus and human validation and correction. The samples that are part of the Big-Bench set were excluded from the TAPE version of the dataset and rewritten in instruction-based format.

Human Benchmark

Human Benchmark was measured on a test set with Yandex.Toloka project with overlap: 3 reviewers per task.

Results for Average Macro F1 and Accuracy are 93.5 / 93.5, respectively.
