We release a dataset containing 23,270 time-locked (0.7s) word-level EEG recordings acquired from 15 participants who read both text that was semantically relevant and irrelevant to self-selected topics.

See code repository for benchmark results. Datasheet is here: data repository.

Explanations of the variables:

  • event corresponds to a specific point in time during EEG data collection and represents the onset of an event (presentation of a word)
  • word is a word read by the participant
  • topic is the topic of the document to which the word belongs to
  • selected topic indicates the topic the participant has selected
  • semantic relevance indicates whether the word is semantically relevant (expressed as 1) or semantically irrelevant (expressed as 0) to the topic selected by the participant
  • interestingness indicates the participant's interest in the topic of a document
  • pre-knowledge indicates the participant's previous knowledge about the topic of the document
  • sentence number represents the sentence number to which the word belongs
  • eeg - brain recordings having a shape of 32 x 2001 for each word

The dataset can be downloaded and used as follows:

import numpy as np
from datasets import load_dataset

# Load the cleaned version of the dataset
d = load_dataset("VadymV/EEG-semantic-text-relevance", "cleaned")

# See the structure of the dataset
print(d)

# Get the first entry in the dataset
first_entry = d['train'][0]

# Get EEG data as numpy array in the first entry
eeg = np.array(first_entry['eeg'])

# Get a word in the first entry
word = first_entry['word']

We recommend using the Croissant metadata to explore the dataset.
