We release a novel dataset containing 23,270 time-locked (0.7s) word-level EEG recordings acquired from participants who read both text that was semantically relevant and irrelevant to self-selected topics.
The raw EEG data and the datasheet are available at https://osf.io/xh3g5/.
See [code repository][1] for benchmark results.
EEG data acquisition:
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:
```py
import numpy as np
from datasets import load_dataset
# Load the cleaned version of the dataset
d = load_dataset("Quoron/EEG-semantic-text-relevance", "data")
# 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.
